Project description:We expanded our previously reported transcriptome profiling of K-562 cells (GSE85187) by analyzing the global transcriptional change upon rescue of endogenous MYB knock down (KD) with SUMO-conjugation deficient mutant of MYB (2KR-MYB) and SUMO-binding deficient mutant of MYB (ANAA-MYB) in comparison with K-562 cells treated with siGENOME non-targeting siRNA (GSE85187) , endogenous MYB KD treated with si2992 (GSE85187), rescue of endogenous MYB KD with wild-type MYB (GSE85187) and rescue of endogenous MYB KD with D152V mutant of MYB (GSE85187).

Project description:Recent genetic studies in mice have established a key role for the nuclear receptor coregulator Trim24 in liver tumor suppression and provided evidence that Trim24 suppresses hepatocarcinogenesis by inhibiting retinoic acid receptor alpha (Rara)-dependent transcription and cell proliferation. However, it is unknown which downstream targets of Rara regulated by Trim24 are critical for tumorigenesis. We report here that loss of Trim24 results in the overexpression of interferon (IFN)/STAT pathway genes in the liver, a process that occurs early in tumorigenesis and is more pronounced in tumors, despite the enhanced expression, late in the disease, of negative regulators such as Usp18, Socs1 and Socs2. Remarkably, Rara haplodeficiency, which was previously shown to suppress tumor development in Trim24-/- mice, also suppresses overexpression of the IFN/STAT pathway, thus providing evidence for a cross-pathway control that may be relevant to the transformation process. Biochemical studies revealed that Trim24 binds to the retinoic acid (RA)-responsive element in the Stat1 promoter in a RA-dependent manner and represses RA-induced transcription from this promoter. Together, these results identify Trim24 as a novel regulator of the IFN/STAT pathway and indicate that Trim24-mediated repression of the IFN/STAT signaling through Rara inhibition may play a critical role in preventing liver cancer. Generation of Trim24-/- mice has been described previously (Khetchoumian et al., 2007) by gene disruption. To generate compound mutant mice with a single allele of Rara deleted in the Trim24 -/- mutant background, we crossed Trim24 -/- mice with Rara+/- mice. The resulting Trim24+/- Rara+/- mice were generated in the hybrid (C57BL/6 (60%), 129/Sv (40%)) genetic background. These double heterozygous Trim24+/- Rara+/- mice were intercrossed to generate Trim24 -/-, Trim24 -/- Rara+/- and wild-type mice. Transcriptional profiling of mice at 5-weeks and 14-weeks of age.

Project description:SPO11-promoted DNA double-strand breaks (DSBs) formation is a crucial step for meiotic recombination, and it is indispensable to detect the broken DNA ends accurately for dissecting the molecular mechanisms behind. Here, we report a novel technique, named DEtail-seq (DNA End tailing followed by sequencing), that can directly and quantitatively capture the meiotic DSB 3’ overhang hotspots at single-nucleotide resolution.

Project description:TRIM24 and TRIM33 interact to form a corepressor complex that suppresses murine hepatocellular carcinoma (HCC). TRIM24 and TRIM33 cooperatively repress retinoic acid receptor dependent activity of VL30 retro-transposons in hepatocytes in vivo. In TRIM24 knockout hepatocytes, VL30 long terminal repeats (LTRs) generate enhancer (e)RNAs and act as surrogate promoter and enhancer elements deregulating expression of neighbouring genes. We show that a VL30 LTR-derived eRNA is essential to activate the lipocalin 13 gene in hepatocytes in vivo. A further consequence of VL30 de-repression is the accumulation of retro-transcribed VL30 DNA in the cytoplasm of TRIM24-mutant hepatocytes and activation of the viral defence/interferon response. VL30 activation therefore modulates gene expression via the enhancer activity of the LTRs and by activation of the interferon response. Both of these processes are genetically linked to HCC development suggesting that VL30 repression by TRIM24 plays an important role in tumour suppression.
