Group 2 innate lymphoid cells (ILC-2s) regulate immune responses to pathogens, allergens, tissue remodeling and metabolic homeostasis in response to cytokines. Positive regulation of ILC-2s through ICOS has been recently elucidated but co-receptor mediated negative regulatory axis is yet to be defined.

View SamplesCD4+ T cell differentiation into multiple T helper lineages is critical for optimal adaptive immune responses. This report identified a novel intrinsic mechanism by which PD-1 signaling imparted regulatory phenotype to FoxP3+ Th1 cells (denoted as Tbet+iTregPDL1 cells) and iTregs. Tbet+iTregPDL1 cells were capable of preventing inflammation in murine models of experimental colitis and experimental graft versus host disease. PDL-1 binding to PD-1 imparted regulatory function to Tbet+iTregPDL1 cells and iTregs by specifically downregulating an endolysosomal protease asparaginyl endopeptidase (AEP)

View SamplesTo inhibit INS expression, we used shRNA to target the INS promoter. We find that knocking down INS expression with such an shRNA targeting the INS promoter significantly affects expression of 259 genes. Overall design: mRNA profiles of EndoC ßH1 with or without shRNA targetting INS promoter were generated by deep sequencing, in triplicate, using Illumina Hiseq 2500.

View SamplesGenetically engineered mouse models of cancer represent valuable biological tools that can be used to filter genome-wide expression datasets generated from human prostate tumours, and identify gene expression alterations that are functionally important to cancer development and progression. In this study, we have generated RNASeq data from tumours arising in two established mouse models of prostate cancer, PB-Cre/PtenloxP/loxP and p53loxP/loxPRbloxP/loxP, and integrated this with published human prostate cancer expression data to pinpoint cancer-associated gene expression changes that are conserved between the two species. In order to identify potential therapeutic targets, we then filtered this information for genes that are either known or predicted to be druggable. Using this approach, we identified the serine/threonine kinase MELK as a potential therapeutic target in prostate cancer. MELK was overexpressed in both human and murine prostate cancers, and high expression of MELK was associated with biochemical recurrence in prostate cancer patients. Overall design: 92 Samples

View SamplesTranscription is a major contributor to genome instability. A main cause of transcription-associated instability relies on the capacity of transcription to stall replication. Such genome instability is increased in RNAPII mutants.
RNA polymerase II contributes to preventing transcription-mediated replication fork stalls.
