Illumina HiSeq 2000
Description
Transcriptional profiling of murine dendritic cells stimulated with LPS and IFNg after shRNA knockdown of redox regulators. Overall design: shRNA targeting redox regulators were delivered to bone marrow derived dendritic cells. Cells were stimulated with LPS and IFNg prior to transcriptional profiling by RNAseq over a time course. Each sample sequenced on two Illumina lanes.

Description
We performed a genome-scale CRISPR screen in a KRAS-mutant pancreatic cancer cell line treated with the MEK inhibitor trametinib, and found that loss of the transcriptional repressor CIC confers resistance to MEK inhibition. We determined that CIC loss also confers resistance to MEK or BRAF inhibition in lung cancer, colorectal cancer, and melanoma cell lines with mutant RAS or BRAF. CIC is a transcriptional repressor that is phosphorylated and inhibited by the MAPK pathway. We hypothesized that inhibition of the MAPK pathway would lead to activation of CIC and repression of CIC target genes. Loss of CIC would therefore restore expression of these genes, conferring drug resistance. To identify the relevant CIC target genes that mediate trametinib resistace, we generated 4 Cas9-expressing cell lines from different lineages and with different RAS or RAF mutations, and generated control (gGFP) or CIC-knockout (gCIC) cell lines. We treated cells with DMSO or trametinib for 24 hours, and performed NRA-seq. We found that trametinib treatment reduces expression of at least one member of the PEA3 family of ETS transcription factors (ETV1, ETV4, and ETV5) in all cell lines assessed, and that loss of CIC results in maintained expression of these genes despite MEK inhibition. We further validated that ETV1, 4, and 5 expression was necessary for resistance mediated by CIC loss; and that ETV1, 4, or 5 expression was sufficient to confer trametinib resistance. Overall design: 4 Cas9-expressing human cancer cell lines (A549, CALU1, HCT116, PATU8902) were used to generate 3 isogenic cell lines with intact CIC (gGFP-1) or knocked out CIC (gCIC-1 or gCIC-2). Each of these 12 cell lines were treated with DMSO or trametinib for 24 hours (duplicates)

Description
Transfection of dsDNA into many mammalian cell types indues the production of type I interferons and interferon-stimulated genes. We performed an siRNA screen to identify genes involved in this innate immune response, and identified Abcf1.

Description
CD8+ T cells can be reprogrammed for better persistence and robust effector function in TME. By performing an in vivo pooled CRISPR-Cas9 mutagenesis screening of metabolism-associated factors, we identify Regnase-1 as a major negative regulator of antitumor responses, whose deficiency results in drastically increased CD8+ T cell accumulation in tumors

Description
The five DLBCL cell lines were treated with R406 to assess the signature of SYK inhibition. In previous studies, R406 decreased the proliferation and induced apoptosis of these surface Ig+ cell lines. In the previous studies, R406 inhibited the autophosphorylation of SYK 525/526 and SYK-dependent phosphorylation of BCR signaling components such as BLNK.
