Project description:Targeted molecular therapy has yielded remarkable outcomes in certain cancers, but specific therapeutic targets remain elusive for many others. As a result of two independent RNA interference (RNAi) screens, we identified pathway dependence on a member of the JAK tyrosine kinase family, TYK2, and its downstream effector STAT1 in T-cell acute lymphoblastic leukemia (T-ALL). Gene knockdown experiments consistently demonstrated TYK2 dependence in both T-ALL primary specimens and cell lines, and a small-molecule inhibitor of JAK kinase activity induced T-ALL cell death. Activation of this TYK2-STAT1 pathway in T-ALL cell lines occurs by gain-of-function TYK2 mutations or activation of IL-10 receptor signaling, and this pathway mediates T-ALL cell survival through upregulation of the anti-apoptotic protein BCL2. These findings indicate that in many T-ALL cases, the leukemic cells are dependent upon the TYK2-STAT1-BCL2 pathway for continued survival, supporting the development of molecular therapies targeting TYK2 and other components of this pathway. Human T-ALL cell line JURKAT cells were transduced with TYK2 (TYK2#2 or #3), STAT1 (STAT1#2 or #3) or control shRNAs (GFP and Luc). Experiment was done in biological duplicate ("dup1" and "dup2") . A total of 12 RNA samples (4 control, 4 TYK2 knockdown and 4 STAT1 knockdown) were used for microarray gene expression analysis.

Project description:Single-nucleus RNA sequencing (snRNA-seq) was used to profile the transcriptome of 16,015 nuclei in human adult testis. This dataset includes five samples from two different individuals. This dataset is part of a larger evolutionary study of adult testis at the single-nucleus level (97,521 single-nuclei in total) across mammals including 10 representatives of the three main mammalian lineages: human, chimpanzee, bonobo, gorilla, gibbon, rhesus macaque, marmoset, mouse (placental mammals); grey short-tailed opossum (marsupials); and platypus (egg-laying monotremes). Corresponding data were generated for a bird (red junglefowl, the progenitor of domestic chicken), to be used as an evolutionary outgroup.

Project description:The LEDGF transcript from the PSIP1 gene was knocked down in Jurkat cells using RNAi technology. The resulting Jurkat-derived cell line (Jurkat-siJK2) was compared to a control cell line (wild type Jurkat) using microarray analysis. Genes identified as being modulated by LEDGF were preferential targets of HIV integration. Keywords: effects of gene knockdown
