Project description:The aim of the study was to identify differentially expressed genes during Gonadal Sex Determination in cattle. We performed a Rna-Seq analysis of XX and XY gonads during sex determination on embryonic days 35 (D35), 39 (D39) and 43 (D43). RNA-seq libraries were prepared from grouped gonads from D35, D39 and D43 males and females.
Project description:We report the differential expression of circRNAs between T-BEAS-2B cells (cadmium-transformed BEAS-2B cells) and C-BEAS-2B cells (passage-matched control BEAS-2B cells) by high-throughput sequencing. T-BEAS-2B cells are BEAS-2B cells transformed by cadmium at 2.0 μM for twenty weeks, and C-BEAS-2B cells are their passage-matched control. RNAs were sequenced on Illumina HiSeq Xten platform in triplicates, and expressions of circRNAs were calculated by TPM (transcripts per kilobase of exon model per million mapped reads). Clean data per sample exceeds 10 GB. We find 235 significantly up-regulated circRNAs and 271 significantly down-regulated circRNAs in T-BEAS-2B cells relative to C-BEAS-2B cells. Our work provides clues and evidence for exploring the mechanism of circRNAs in cadmium carcinogenesis.
Project description:To profile the human substrate degradome of the SARS-CoV-2 main viral protease and to investigate whether 3CLpro cleavage of cellular substrates dampens host antiviral responses induced by type I interferons, we treated BEAS-2B cells with interferon-alpha (N = 3), interferon-beta (N = 3), or vehicle (N = 3), retrieve and exposed native proteome extracts from human embryonic kidney to 3CLpro cleavage. Then, N Terminal Amine Labeling of Substates (TAILS) was used to identify the substrates. Here, heavy [+34] isotope dimethyl labeling is performed at the whole protein level in the 3CLpro-exposed samples, and the P1' side of substrates substrates was revealed by comparing to the samples exposed to inactive mutant labeled with ligh [+28 Da] dimethyl.
Project description:BEAS-2B cells are human bronchial epithelial cells, and often used as a in vitro model for the detection of potential pulmonary toxicity of chemicals. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated genes after treated with chemical substance
