Dr. James, a post doctoral scientist in the lab of Ruslan Rafikov at the University of Arizona, received the travel award to facilitate her participation in the SfRBM Conference on Redox Biology and Medicine, taking place November 20-23 in Las Vegas. Dr. James’ research, which he will be presenting as a poster, describes the NFU1G206C mutation induces a metabolic shift in the PASMC via excessive ROS production, resulting in a hyper-proliferative and apoptosis resistant phenotype, recapitulating pulmonary arterial hypertension (PAH) and presents a novel and first cellular model to study PAH. Dr. James stated that “the iCelligence radically changed the way we do research at our lab. Instead of time consuming growth kinetic assays which are prone to human error, we now have cell proliferation data from the iCelligence which closely corroborates with the proliferation patterns we observed in our mutant animals. This unique technology gave us insight to study unexplored ideas to effectively understand the disease.”
Ms. Adams, a doctoral student in the lab of Lindsey Shaw at the University of South Florida, received the travel award to facilitate her participation in the ASM Conference on Biofilms, taking place October 7-11 in Washington DC. Ms. Adams’ research, which she will be presenting as a poster, describes the use of a transposon library to identify genes involved in biofilm formation in Acinetobacter baumannii. Adams stated that the xCELLigence instrument is playing “a major role in my research, coupling the standard endpoint biofilm assay (crystal violet staining) with a real-time analysis of the attachment of the lead mutants that show distinct phenotypes. For the data to be presented at this conference, over 60 mutants have already been screened.” She went on to say “We will be continuing our screen and utilizing this invaluable assay to screen over 300 mutants to get a true understanding of the genes responsible for regulating biofilm formation in A. baumannii. Without the xCELLigence system, this project would not be possible as we are already finding unique phenotypes that have never been seen before in A. baumannii. To our knowledge, there is only a handful of genes proven to regulate biofilm formation and even in the earliest stages of this project we have been able to identify a plethora of novel regulators thanks to this unique system.” View Ms. Adams’ research poster here.
Ms. Vlachodimou, a Ph.D. candidate in the Department of Medicinal Chemistry at Leiden University (Netherlands), was selected for the oral and poster presentations that she will deliver at the Gordon Research Conference on Membrane Transport Proteins in June, 2018. Using an xCELLigence instrument, Ms. Vlachodimou has developed a whole cell label-free assay for monitoring the inhibition of membrane transporters. This approach provides a simple means of studying this class of proteins without having to use traditional techniques that involve radio-labeled ligands.
Dr. Warnes, the Flow Cytometry Core Facility manager at the Blizard Institute of Queen Mary London University, was selected for the oral presentation that he will deliver at the CYTO 2018 meeting taking place in April. Using the NovoCyte3000 flow cytometer, Dr. Warnes has developed a polychromatic immunophenotyping protocol capable of analyzing 80 different subpopulations of Jurkat cells displaying different levels of regulated cell death processes. In addition to assessing the levels of apoptosis, necroptosis, and autophagy, this protocol also evaluates ER stress, parthanatos, and DNA damage. Click here to view his full presentation.
ACEA congratulates Mr. Khokhar for winning the Fall 2017 Research Travel Award.
Mr. Khokhar was selected for his poster presentation which examines the impact of a matrix metalloproteinase, called sperm acrosomal SLLP1 binding (SAS1B), on breast cancer cell proliferation, migration, and invasion. Khokhar, who is a research scientist in the laboratory of Eusebio Pires at the University of Virginia, is using the xCELLigence DP instrument to evaluate the consequence of SAS1B expression on these different facets of breast cancer cell behavior. He’ll be showing this poster at the AACR annual conference April 14-18, 2018 in Chicago, click here to view his poster.
ACEA congratulates Dr. Mariam Ferrer for winning the Summer 2017 Research Travel Award.
Dr. Ferrer was selected for her poster presentation on the real-time analysis of bacterial biofilms, which she presented at the Eurobiofilms conference in Amsterdam over the week of September 19-22, 2017. Working in the lab of Dr. Alex Mira at the Center for Advanced Research in Public Health in Valencia, Spain, Ferrer is helping to pioneer the use of xCELLigence® for pure and applied studies of the surface attached bacterial communities known as biofilms, which play a major role in human infections. When compared with their free-floating lifestyle, bacteria within an immobilized biofilm display altered gene expression profiles and dramatically increased antibiotic resistance. Screening for new antibiotics and quantitatively evaluating the efficacy of drugs against different species in the biofilm state is expected to improve the efficiency with which these infections are treated.
ACEA congratulates Dr. Lara Campana and Dr. Ellen Menkhorst for winning the Spring 2017 Research Travel Award.
Dr. Campana was selected for her podium presentation entitled “A high throughput screening flow cytometry approach for the study of cell signaling in phagocytosing macrophages”, which she presented at the CYTO2017 conference in Boston, MA during the week of June 10-14. As a postdoctoral fellow in Stuart Forbes’ lab within the MRC Centre for Regenerative Medicine at the University of Edinburgh, Campana developed an assay for the facile tracking of macrophage phagocytosis of apoptotic thymocytes using flow cytometry. Beyond identifying macrophages that have engulfed thymocytes, the assay permits tracking of specific signaling cascades via intracellular phosphoproteins. The efficiency of this assay opens up the possibility of screening for small molecule modulators of phagocytosis in a high throughput manner.
Dr. Menkhorst was awarded for her podium presentation entitled “Fetal-maternal crosstalk in the decidua: Invasive trophoblast promote endometrial stromal fibroblast decidualization”, which she will deliver at the Society for the Study of Reproduction meeting taking place July 13-16 in Washington, DC. As a postdoctoral fellow in Embryo Implantation at the Hudson Institute of Medical Research in Melbourne, AUSTRALIA, Menkhorst’s work focuses on understanding how the extravillous trophoblast induces remodeling of the uterine lining in order to facilitate trophoblast invasion. Using xCELLigence Real-Time Cell Analysis (RTCA) she has characterized the impact that trophoblast-secreted factors have on endometrial stromal cells, and vice versa. Because trophoblast invasion/implantation is essential for fetal health and maturation, understanding these details may lead to novel means of preventing miscarriage and preeclampsia.
ACEA congratulates Dr. Calum Robb and Dr. Rentian Wu for winning the Winter 2017 Research Travel Award.
Dr. Robb, a postdoctoral fellow in the laboratory of Dr. Adriano Rossi at the University of Edinburgh Medical School, was selected for his poster entitled “Flow cytometric assessment, quantification and regulation of human neutrophil extracellular traps” which he will present at the CYTO 2017 Conference being held June 10-14 in Boston, MA. Beyond their well characterized role as phagocytes, granulocytic neutrophils are also able to ensnare and neutralize pathogens using a secreted extracellular fibril matrix consisting of DNA, histones, and a variety of anti-bacterial proteins. Though the employment of these neutrophil extracellular traps (NETs) is thought to be an evolutionarily ancient defense strategy, the mechanisms regulating this process are not yet fully understood. With the goal of elucidating these mechanisms, Robb developed a NovoCyte® flow cytometer-based assay that enabled him to track changes in NET formation when key proteins or pathways were pharmacologically modulated. Using this approach, Robb probed the roles of superoxide anion, intracellular calcium pools, and the phospholipase C pathway in NET formation. The efficiency and versatility of Robb’s assay are expected to accelerate the rate of progress in this relatively new field.
Dr. Wu, a postdoc in the lab of Dr. Robert Diasio at the Mayo Clinic, was selected for his poster entitled “Trimethylation and acetylation of histone H3K27 modulates 5-fluorouracil response by regulating DPYD expression” which he will present at the 2017 American Association for Cancer Research meeting taking place April 1-5 in Washington D.C. Though it is one of the most widely used chemotherapy drugs, the antimetabolite 5-fluorouracil (5-FU) displays substantial variability in its efficacy and toxicity among patients. This variability is due, at least in part, to differences in the activity of DPD, the enzyme which initiates the catabolic degradation of 5-FU to inactive metabolites. Though mutations in the DPD gene can affect 5-FU metabolism, these variants are rare and cannot by themselves explain the variation in DPD activity that is observed among patients. In search for the cause of variable DPD activity, Wu used the xCELLigence® Real-Time Cell Analyzer in combination with both chemical inhibitors and genetic approaches to demonstrate that the DPD gene is epigenetically regulated by histone modification at promoter and enhancer regions. This new layer of information has the potential to help clinicians predict more accurately how a patient will respond to 5-FU treatment.
We would like to congratulate Dr. Miriam Butler and Dr. Jason Maynes for winning the ACEA Research Travel Award for Spring 2016.
Dr. Butler, a postdoctoral fellow working in the labs of Dr. Paul Rennie and Dr. Artem Cherkasov at the Vancouver Prostate Centre, was selected for her work entitled “Discovery and characterization of small molecules targeting the DNA binding ETS domain of ERG in prostate cancer”, which she will present as a poster at the AACR meeting taking place April 1-5 in Washington DC. Chromosomal rearrangements which cause overexpression of the ERG transcription factor are associated with aggressive disease (including enhanced metastatic potential) and occur in 50% of prostate cancers. Dr. Butler’s work has focused on using rational in silico screening methods to identify drugs capable of disrupting ERG’s DNA binding capabilities. Subsequent analyses of drug candidates demonstrated one molecule, VPC-18005, to directly bind ERG and disrupt its interaction with DNA. VPC-18005 was also shown to inhibit cell invasion and migration (using the xCELLignece RTCA) in ERG-expressing cells, and to reduce metastasis in zebrafish xenograft models.
Dr. Maynes, Director of Research, Anesthesia and Pain Medicine at the Hospital for Sick Children in Toronto, was selected for his work entitled “Measuring Clinical Cardiac Effect and Toxicity”, which he will present in a podium talk at the QMB Meeting taking place March 16-17 in Shanghai. Using iPSC-derived cardiac tissue in conjunction with cardiomyocyte functional analysis using impedance monitoring by xCELLigence RTCA, the Maynes group studies cardiac disease, cardiac drug effects and cancer chemotherapy-induced cardiac dysfunction. Beyond mechanistic analyses, they conduct high-throughput drug screening to identify agents that attenuate or eliminate these disease phenotypes.
We would like to congratulate Dr. Slobodan Culina, a post-doctoral researcher at INSERM (France), and Dr. Scott Boitano, a Professor of Physiology at The University of Arizona Health Sciences (USA), for winning the ACEA Research Travel Award for Spring 2016.
Dr. Culina is awarded for his presentation entitled “Lack of central tolerance facilitates the emergence of high avidity antigen-experienced ZnT8-reactive CD8+ T cells in type 1 diabetic patients”, which was presented at the FOCIS 2016 Annual Meeting June 22-25, 2016. In this study, Dr. Culina utilized the xCELLigence Real-Time Cell Analysis (RTCA) system to quantify the dynamic killing activities of beta cell antigen specific CD8+ T cells (from Type 1 Diabetic patients and healthy subjects) against adherent pancreatic beta cells.
Dr. Boitano is awarded for his talk entitled “Drug development for protease-activated receptor 2 (PAR2)”, which was presented at the 3rd Conference on Impedance-Based Cellular Assays, August 9 – 12, 2016. PAR2 is associated with a variety of inflammatory conditions, including asthma and pain. Elucidation of PAR2 signaling contributions to disease has been hindered by the lack of potent, efficacious antagonists, and/or biased-ligand signaling agonists and antagonists. The team led by Dr. Boitano utilized the xCELLigence impedance-based cellular assay as the primary, high capacity screening tool for discovering novel PAR2 ligands. Read Dr. Boitano’s latest publication here.
We would like to congratulate Dr. Farah Sheikh, an associate professor in the Department of Medicine at University of California San Diego, for winning the ACEA Research Travel Award for Winter 2016.
Dr. Sheikh is awarded for her research using patient-derived induced pluripotent stem cells (iPSCs) to model the disease arrhythmogenic right ventricular cardiomyopathy (ARVC). ARVC results from defects of the desmosomal cell-cell junction and gives rise to a broad spectrum of symptomatic severities. Sheikh’s work aimed to determine whether iPSCs from ARVC patients could recapitulate phenotypes associated with early stages of the disease. Using ACEA Bioscience’s xCELLigence RTCA Cardio instrument, which monitors cardiomyocyte contraction strength and periodicity in real-time and without the use of labels, Sheikh was able to show strong correlation between the behavior of patient’s hearts and their derivative cardiomyocyte cell lines. This “disease in a dish” model system now opens the door for Sheikh and colleagues to further explore the molecular mechanisms underlying ARVC, and to probe for therapeutic interventions. Dr. Sheikh will be presenting her work at the Keystone Symposium, focused on Cardiac Development, Regeneration and Repair, taking place April 3-7 in Snowbird, Utah.
We would like to congratulate James Murray, a doctoral student under Dr. James Murphy in the Mitochondrial Biology & Radiation Research Centre at the Institute of Technology Sligo (Ireland), for winning the ACEA Research Travel Award for Fall 2015.
James Murray is awarded for his research on novel anticancer drug hybrids, wherein two chemotherapeutic compounds are covalently tethered to one another to form a single molecule with two different modes of action. Citing that the 20% oxygen atmosphere that human cells are typically cultured in does not reflect in vivo oxygen concentrations of 3-5%, or the hypoxic environment of tumors (~1%), Murray used the xCELLigence® RTCA DP system to evaluate the effect of drug hybrids on tumor and non-tumor cell lines under hypoxic conditions. ACEA’s impedance-based label-free xCELLigence RTCA assay was chosen over alternative viability assays such as MTT (which monitors mitochondrial activity) due to the effect that varying oxygen concentration can have on cellular metabolism. RTCA detected not only drug-induced changes in cell number but also the kinetics of drug action. Murray commented that “RTCA was invaluable in defining optimal seeding densities and drug concentration range and enabled us to detect instances of cell recovery which may otherwise have been overlooked”. He will be presenting this work, entitled “Selective anticancer activity of novel endoperoxide-naphthalimide hybrid compounds in vitro”, at the Irish Association for Cancer Research Annual meeting (IACR) in Ireland, February 25-26, 2016. His latest publication can be viewed here: “In vitro oxygen availability modulates the effect of artesunate on HeLa cells” (Anticancer Res. 2014 Dec;34(12):7055-60).
We would like to congratulate Hannah Yong, a doctoral student in the Perinatal Medicine Pregnancy Research Centre at The Royal Women’s Hospital (Australia), and Canan Schumann (Pharm.D.), a doctoral student in the Department of Pharmaceutical Sciences at Oregon State University (USA), for winning the ACEA Research Travel Award for Summer 2015.
Ms. Yong is awarded for her research on the manner in which the stromal cells of the uterus regulate the function of trophoblast cells during placentation (after embryo implantation). Yong used the xCELLigence® RTCA DP system to evaluate the effect that media conditioned by decidualised endometrial stromal cells has on fetal extravillous trophoblast cells. Yong demonstrated that reduced expression of the activin receptor ACVR2A in the stromal cells significantly increases adhesion, proliferation, migration and invasion of the trophoblast cells. She presented this work, entitled “Altered activin receptor ACVR2A expression in pre-eclampsia contributes to abnormal placentation”, at the International Federation of Placenta Associations meeting in Brisbane, Australia, September 8-11, 2015.
Dr. Schumann is awarded for his research on combining gene therapy and traditional chemotherapy to increase the efficacy of cancer treatment regimes. Specifically, Schumann has studied a combination therapy involving siRNA-mediated knockdown of the DJ-1 oncogene along with cisplatin administration. Using xCELLigence® real-time impedance monitoring he has demonstrated that this combined therapy is more effective at killing cancer cells than either therapy alone. Schumann recently presented this work at the American Association of Pharmaceutical Scientists’ annual meeting in Orlando, Florida on October 25-29, 2015. His poster entitled “A Nanomedicine Based Combinatorial Approach for the Treatment of Ovarian Cancer Using Gene and Chemotherapy” can be viewed here.
We would like to congratulate Dr. Filomain Nguemo, a group leader at the University of Cologne Medical School, and Dr. Lu Han, a postdoctoral researcher at the University of Pittsburgh, for winning th ACEA Research Travel Award for Spring 2015.
Dr. Filomain Nguemo is awarded for his upcoming KEYNOTE lecture entitled “Application of the xCELLigence System and Stem Cells for Medicinal Plant Extract Safety and Efficacy Assessment”, which he will be presenting at the 2nd International Conference of RUAD-EURD on June 9-11, 2015. In his presentation he will discuss the utility of the xCELLigence® RTCA Cardio system in conjunction with stem cells for assessing the effect of medicinal plant extracts.

Dr. Lu Han is awarded for her poster entitled “Study of Familial Hypertrophic Cardiomyopathy Using Patient Specific Induced Pluripotent Stem Cells” which was presented at the Weinstein Cardiovascular Development Conference on April 30 – May 2, 2015. She used the xCELLigence® RTCA Cardio system to analyze the abnormal electrophysiological properties of HCM cardiomyocytes in a monolayer. Dr. Han’s analysis included a comparison of the arrhythmogenic events in both control and HCM CMs, and an evaluation of the effect of multiple drug treatments over 24 hours.

Dr. Michael J. Smout, a research officer at James Cook University, and Dr. Mukerrem Betul Yerer-Aycan, an associate professor at the University of Erciyes in Turkey, are the two winners of the Spring 2014 Grant.
Dr. Michael Smout was awarded for his podium presentation entitled “A granulin growth factor secreted by the carcinogenic liver fluke, opisthorchis viverrini, and ITS role in wound healing and carcinogenesis”, which he presented at the International Congress of Parasitology (ICOPA) XIII on August 10-15, 2014 in Mexico City, Mexico. Dr. Smout used xCELLigence real-time cell analysis in conjunction with other technologies like gene silencing to demonstrate a carcinogenic effect for a novel granulin growth factor secreted by the liver parasite, Opisthorchis viverrini.
Dr. Mukerrem Betul Yerer-Aycan was awarded for her podium presentation entitled “Prediction of mechanism of some natural anticancerogen agents by using kinetic cell based morphological screening”, which she presented at the 4th World Congress on Cancer Science & Therapy on October 20-22, 2014 in Chicago, IL, USA. She used the xCELLigence technology to detect the biological activities of natural compounds. Based on impedance-based Time-dependent Cell Response Profiles (TCRP), in comparison to those of the 2000 chemical compounds reported in an earlier study ( Chem Biol 2009; 16 (7): 712-723), she was able to identify novel mechanisms of action for many of the compounds tested.
Monica Charpentier, a graduate student with Dr. Stuart S. Martin at the University of Maryland School of Medicine, and Dr. Babu Sajesh, a post doctoral fellow in the lab of Dr. Kirk McManus at Manitoba Institute of Cell Biology, are the two winners of the Winter 2014 Grant.
Monica Charpentier was awarded for her poster presentation entitled “Breast tumor stem cells have Increased microtentacles promote reattachment and that can be targeted therapeutically with curcumin“, which she presented at the Keystone Symposia: Stem Cells and Cancer February 2-7, 2014 in Alberta Canada. She demonstrated that real-time monitoring of cell reattachment with xCELLigence can be used to study how breast tumor cells use plasma membrane microtentacles to reattach during metastasis. The xCELLigence technology provided a novel method to differentiate between stem-like and non-stem-like cancer cells, as well as a platform to test potential cancer therapies. Click the links to read more about her poster and 2014 publication in Cancer Research.
Dr. Babu Sajesh was awarded for his poster presentation entitled “Synthetic lethal RAD54B-deficient colorectal killing of cells by targeting SOD1 cancer”, which he presented at the 2014 AACR Annual Meeting on April 5-9, in San Diego, CA, USA. Dr. Sajesh used xCELLigence RTCA technology to detect cell proliferation and death induced by SOD1 inhibitors in different genetic backgrounds. He demonstrated that RAD54B deficiency causes increased sensitivity to SOD1 inhibition. The label-free nature of the RTCA assay proved advantageous in that it enabled them to avoid potential artifacts associated with using a nuclear dye. Read his poster and 2013 publication in Genetics.
ACEA also presented an honorable mention to Dr. Jacques-Aurélien Sergent, a Nanotoxicologist at Solvay in Belgium. His poster entitled “Impedancemetry and toxicology of nanomaterials: a review on an emerging alternative method” was presented at Nanotoxicology 2014 on April 23-26. See his poster here.
Dr. Kate Berezowski, a graduate student with Dr. Yu (Dorothy) Huang at Alberta Centre for Toxicology, Department of Physiology and Pharmacology, University of Calgary, was awarded for her poster presentation entitled “Development of an In Vitro Microelectric Sensing Technique to Assess Cell Cytotoxicity of Ocular Irritants” which she will be presenting at the 53rd Annual SOT meeting on March 24-27, in Phoenix, Arizona, USA.
The Draize Rabbit Eye Test is currently the most widely accepted method for assessing ocular irritancy of chemicals. However, due to a variety of limitations and concerns with the test, along with changes to legislation, such as the European Union Cosmetics directive regarding the use of experimental animals, alternative methods are being developed at a rapid pace, none of which can singularly replace the Draize Rabbit Eye Test. The study led by Berezowski in Huang’s lab sought to develop and optimize a high throughput in vitro assay using the xCELLigence RTCA system to measure the potential of chemicals, mixtures and commercial products to cause eye irritation. The time-dependent IC50’s derived from RTCA analyses show good correlation with historical Draize data, demonstrating the xCELLigence RTCA technology to be a high throughput, reproducible alternative to an ocular irritation test.
Dr. Sarah Steinbach, a postdoctoral fellow in the lab of Dr. Mansoor Husain at the University Health Network in Canada, received an honorable mention for the Fall 2013 award for her innovative use of the xCELLigence system. Her poster entitled “Human patient-specific SKP-derived vascular smooth muscle cells carry signatures of type II diabetes” was presented at American Heart Association Scientific Session. Dr. Steinbach successfully utilized xCELLigence RTCA technology to quantitatively evaluate the contraction of PS-VSMC derived from clinical samples. This builds upon her earlier findings which were published as “Directed differentiation of skin-derived precursors into functional vascular smooth muscle cells.”
Dr. Asif Iqbal, a postdoctoral fellow at University of Oxford All in UK, was awarded for his poster presentation entitled “The use of label free electrical impedance sensing technologies for real time analysis of primary murine macrophage chemotaxis and signaling” at the 11th World Congress on Inflammation 2013 in Natal, RN, Brazil.
Dr. Iqbal’s work demonstrated that the xCELLigence systems can effectively monitor dose dependent migration, adhesion and spreading of large numbers of primary murine macrophages toward a range of CC chemokines and other chemoattractants. His work demonstrates that ACEA’s Cell Invasion and Migration (CIM) plate, which is used with the xCELLigence DP system, provides a rapid and reproducible means of monitoring macrophage chemotaxis in a label-free and real-time manner. His latest work was published in PLoS ONE, March 2013; 8 (3), e58744.
Dr. Kerry Manton, a Research Fellow at All Queensland University of Technology in Australia, was awarded for her poster presentation entitled “Stratum basale keratinocyte cell surface glycoprotein expression of the CDCP1 during epidermogenesis and ITS role in keratinocyte migration” at the TEMTIA Meeting in 2013 Alicante, Spain.
Primary human cells are notoriously variable in their responses to different stimuli. The real-time data acquisition of the xCELLigence system enabled Dr. Manton to monitor the cell migration rates continuously, thereby removing experimental variability. Her novel approach to studying epidermal wound healing is highlighted in the British Journal of Dermatology, March 2013; 168 (3), 496-503.
An Associate Professor at Georgetown University Medical Center was awarded for his research presentation entitled “Prevention of osteosarcoma metastasis by inhibiting ezrin” at the Symposium on Paediatric Cancer Research at the INTERFACE 2013 in Vienna, Austria.
The invasion assay described in his work is based on the disruption of endothelial barrier functions as the co-cultured tumor cells invade through the HUVEC monolayer. The cell barrier function disruption leads to a sharp decrease in the cell index that directly correlates with the invasive capacity of tumor cells. For technical details, please see Dr. Üren’s video publication (J. Exp Vis, 2011;(50), e2792.)
