Abstracts of Presentations at the Association of Clinical Scientists 143 < sup > rd < /sup > Meeting Louisville, KY May 11-14,2022
Conclusion: These assays are suitable for routine diagnostic. The UltraFast NextGenPCR is the fastest with average time (30mins), followed by Agilent (2 hrs) and MassArray (6hrs). Upon completion of this activity, participants should be able to examine, measure and compare results from different assays for SARS detection, evaluate and diagnose accurately, as well as being able to plan, organize and recommend a diagnostic procedure for diagnostic laboratory. Key words: SARS-CoV-2, RNA extraction, RT-PCR, limit of detection, quantification cycle, COVID-19, in vitro diagnostic tests, Agilent, Massarray, Ultrafast. [20] From t...

Single-cell RNA profiling identifies diverse cellular responses to EWSR1/FLI1 downregulation in Ewing sarcoma cells
ConclusionsWe show that time-dependent changes induced by suppression of oncogenicEWSR1/FLI1 expression induces dormancy, with different subpopulation dynamics. Cells re-entering the proliferative cycle show enhanced stem-like characteristics, whereas those remaining dormant for prolonged periods appear to survive through autophagy. Cells with these characteristics identified in exponentially growing cell populations and in tumor xenografts may confer drug resistance and could potentially contribute to metastasis.

Fusion protein EWS-FLI1 is incorporated into a protein granule in cells
We examined EWSR1 and EWS-FLI1 activity in Ewing sarcoma cells by siRNA-mediated knockdown and RNA-seq analysis. More transcripts were affected by the EWSR1 knockdown than expected and these included many EWS-FLI1 regulated genes. We reevaluated physical interactions between EWS-FLI1, EWSR1, and RNA Pol II, and employed a cross-linking based strategy to investigate protein assemblies associated with the proteins. The LC domain of EWS-FLI1 was required for the assemblies observed to form in cells. These results offer new insights into a protein assembly that may enable EWS-FLI1 to bind its wide network of protein partners a...

Role of Tropomyosin-related kinase B receptor and brain-derived neurotrophic factor in cancer.
Abstract The tropomyosin-related kinase B (TrkB) receptor is a member of the neurotrophic tyrosine kinase receptors family and, together with the brain-derived neurotrophic factor (BDNF), plays an important role in the development of breast cancer, lung cancer, neuroblastoma, colorectal cancer, leukemia, cervical cancer, gallbladder cancer, gastric cancer, kidney cancer, Ewing's sarcoma, esophageal cancer, and head and neck cancer. Overexpression of these two factors has been associated with increased processes involved in carcinogenesis, such as invasion, migration, epithelial-mesenchymal transition (EMT), angiog...
