SPOP-containing complex regulates SETD2 stability and H3K36me3-coupled alternative splicing

Trimethylation of histone H3K36 is a chromatin mark associated with active gene expression, which has been implicated in coupling transcription with mRNA splicing and DNA damage response. SETD2 is a major H3K36 trimethyltransferase, which has been implicated as a tumor suppressor in mammals. Here, we report the regulation of SETD2 protein stability by the proteasome system, and the ...

Global histone modification profiling reveals the epigenomic dynamics during malignant transformation in a four-stage breast cancer model

Background Epigenetic regulation has emerged to be the critical steps for tumorigenesis and metastasis. Multiple histone methyltransferase and demethylase have been implicated as tumor suppressors or oncogenes recently. But the key epigenomic events in cancer cell transformation still remain poorly understood. Methods A breast cancer transformation model was established via stably ...

The Selective Activation of p53 Target Genes Regulated by SMYD2 in BIX-01294 Induced Autophagy-Related Cell Death

Transcription regulation emerged to be one of the key mechanisms in regulating autophagy. Inhibitors of H3K9 methylation activates the expression of LC3B, as well as other autophagy-related genes, and promotes autophagy process. However, the detailed mechanisms of autophagy regulated by nuclear factors remain elusive. In this study, we performed a drug screen of SMYD2-/- cells and ...
