Project description:We demonstrate that global effects of TRIM71 on the cellular transcriptome of mouse embryonic stem cells (mESCs) are largely attributable to its RNA binding activity, and map the transcriptome-wide targets of wild-type TRIM71, NHL domain mutant TRIM71, and RING domain mutant TRIM71.
Project description:We demonstrate that global effects of TRIM71 on the cellular transcriptome of mouse embryonic stem cells (mESCs) are largely attributable to its RNA binding activity. We observe that target repression by TRIM71 in mESCs occurs predominantly through transcript degradation. We identify a core set of targets consistently regulated by TRIM71 in different human and mouse cell lines.
Project description:In order to identify MBNL1-dependent changes in MBNL1 target transcript stability, MBNL1 levels in MDA-MB-231 breast cancer cells were stably knocked-down using short-hairpin RNAs. The cells were then treated with alpha-amanitin to inhibit transcription, RNA was isolated at 0 and 9 hours post-alpha-amanitin treatment, and the samples were transcriptomically profiled.
Project description:We report that Trim71 mutation does not lead to significant changes within the core regulatory network of mES cells, however, there is an upregulation of specific genes involved in neural differentiation. We thus conclude that Trim71 KO mES cells are poised for differentiation.
