Project description:The established cell lines RT4, 5637 and T24 from human bladder TCC were obtained from the Cell Bank of the Federal University of Rio de Janeiro, Brazil. The 5637 cells harbor two TP53 mutations, at codon 72 (Arg . Pro) and codon 280 (Arg . Thr).T24 cells contain a TP53 allele encoding an in-frame deletion of tyrosine 126. Both cell lines were established from high-grade bladder tumors. No specific mutations were detected in RT4 cells, which had been established from a low-grade papillary bladder tumor. The RT4 and T24 cell lines were maintained in DulbeccoM-^Rs modified EagleM-^Rs medium (Sigma-Aldrich, Inc, St Louis, MO, USA), and the 5637 cells were kept in Roswell Park Memorial Institute medium (Sigma-Aldrich). Both media were supplemented with 10% fetal bovine serum (Cultilab Ltd, Campinas, Brazil), 100 U/mL penicillin G (Sigma-Aldrich), 100 U/mL streptomycin (Sigma-Aldrich) and 1% kanamycin sulfate (Amresco, Branded Products Group, Solon, OH, USA); cells were cultured at 37M-:C in an atmosphere of 5% CO2. A pooled reference design was chosen. More specifically, each array was hybridized with the same reference sample labeled with Cy5, while the experimental samples (control or treated) were labeled with Cy3.

Project description:For the assessment of host response dynamics to SARS-CoV and SARS-CoV-2 infections in human airway epithelial cells at ambient temperature corresponding to the upper or lower respiratory tract. We performed a temporal transcriptome analysis on human airway epithelial cell (hAEC) cultures infected with SARS-CoV and SARS-CoV-2, as well as uninfected hAEC cultures, incubated either at 33°C or 37°C. hAEC cultures were harvested at 24, 48 72, 96 hpi and processed for Bulk RNA Barcoding and sequencing (BRB-seq), which allows a rapid and sensitive genome-wide transcriptomic analysis in a highly multiplexed manner. Transcriptome data was obtained from a total of 7 biological donors for pairwise comparisons of SARS-CoV or SARS-CoV-2 virus-infected to unexposed hAEC cultures at respective time points and temperatures.

Project description:The SARS-CoV-2 virus is continuously evolving, with appearance of new variants characterized by multiple genomic mutations, some of which can affect functional properties, including infectivity, interactions with host immunity, and disease severity. The rapid spread of new SARS-CoV-2 variants has highlighted the urgency to trace the virus evolution, to help limit its diffusion, and to assess effectiveness of containment strategies. We propose here a PCR-based rapid, sensitive and low-cost allelic discrimination assay panel for the identification of SARS-CoV-2 genotypes, useful for detection in different sample types, such as nasopharyngeal swabs and wastewater. The tests carried out demonstrate that this in-house assay, whose results were confirmed by SARS-CoV-2 whole-genome sequencing, can detect variations in up to 10 viral genome positions at once and is specific and highly sensitive for identification of all tested SARS-CoV-2 clades, even in the case of samples very diluted and of poor quality, particularly difficult to analyze.
