(Submitter supplied) The Mediator complex functions as a control center orchestrating diverse signalings, gene activities, and biological processes. However, how Mediator subunits determine distinct cell fates remains to be fully elucidated. Here, we show that Mediator MED23 controls the cell fate preference that directs differentiation into smooth muscle cells (SMCs) or adipocytes. Med23-deficiency facilitates SMC differentiation but represses adipocyte differentiation from the multipotent mesenchymal stem cells. more...

(Submitter supplied) We examined how MED23 regulates SRF-targeted genes by comparing WT and Med23 KO mouse embryonic fibroblasts (MEFs) in the presence or absence of serum-stimulation (for 30 and 90 min). To investigate whether MAL antagonizes MED23 in the adipocyte lineage program, we compared the gene expression changes resulting from Mal overexpression (oxMal) and Med23 deficiency (siMed23) in 10T1/2 cell.

(Submitter supplied) The Mediator complex orchestrates multiple transcription factors with the Pol II apparatus for precise transcriptional control. However, its interplay with the surrounding chromatin remains poorly understood. Here, we analyze differential histone modifications between WT and MED23-/- (KO) cells and identify H2B mono-ubiquitination at lysine 120 (H2Bub) as a MED23-dependent histone modification. Using tandem affinity purification and mass spectrometry, we find that MED23 associates with the RNF20/40 complex, the enzyme for H2Bub, and show that this association is critical for the recruitment of RNF20/40 to chromatin. more...

(Submitter supplied) K-RAS activating mutations occur frequently in non-small cell lung cancer (NSCLC), leading to aberrant activation of Ras-MAPK signaling pathway that contributes to the malignant phenotype. However, the development of Ras-targeted therapeutics remains challenging. Here, we show that MED23, a component of the multisubunit Mediator complex that is known to integrate signaling and gene activities, is selectively important for Ras-active lung cancer. more...

(Submitter supplied) We sequenced mRNA from 12 single newborn mouse calvaria tissues ( from 3 control and 3 Med23-/- cKO mice from a litter; 3 wildtype and 3 Runx2+/- mice from another litter) to investigate the correlation between Med23 and Runx2 in terms of affect on the mRNA level by their deficiencies. We find there is a positiove correlation in gobal gene expression affected by defiencies of the two genes.

(Submitter supplied) Skeletal muscle stem cells (MuSC), also called satellite cells, are indispensable for maintenance and regeneration of adult skeletal muscles. Yet, a comprehensive picture of the regulatory events controlling the fate of MuSC is missing. Here, we determine the proteome of MuSC to design a loss-of-function screen, and identify 120 genes important for MuSC function including the arginine methyltransferase Prmt5. more...

(Submitter supplied) Mediator complex function as an integrative hub for transcriptional regulation. Here we show that Mediator subunit MED23 regulate glucose and lipid metabolism via FOXO1 in liver. Here, we have generated a liver-specific Med23-knockout (LMKO) mouse and found that Med23-deletion in liver improved glucose and lipid metabolism, as well as insulin responsiveness, and prevented diet-induced obesity. Mechanistically, MED23 participated in gluconeogenesis and cholesterol synthesis by interacting with FOXO1. more...

(Submitter supplied) Affymetrix MOE430A arrays. Mouse embryonic fibroblasts (MEFs) from E11 passaged through crisis. Starved in 0.5% FBS for 16 h then stimulated by 20% serum final concentration for 30 minutes. The purpose was to identify genes affected by the loss of MED23 protein (subunit of the mediator complex). Samples were assayed in duplicate (Set 1 and Set 2) for starved state and serum state cells.

(Submitter supplied) MED23, a subunit of the Mediator coactivator complex, is important for the expression of a subset of MAPK/ERK pathway-dependent target genes; however, the genes in this subset varies between cell types. MAPK/ERK pathway-dependent processes are essential for T-cell development and function, but whether MED23 has a role in this context is unknown. We generated Med23 conditional knockout mice and induced Med23 deletion in early T cell development using the lineage specific Lck-Cre transgene. more...

(Submitter supplied) The differentiation and regeneration of skeletal muscle from myoblasts to myotubes involves myogenic transcription factors, such as myocardin-related transcription factor A (MRTF-A) and serum response factor (SRF). In addition, post-transcriptional regulation by miRNAs is required during myogenesis. Here we provide evidence for novel mechanisms regulating MRTF-A during myogenic differentiation. Endogenous MRTF-A protein abundance and activity decreased during C2C12 differentiation, which was attributable to miRNA-directed inhibition. more...

(Submitter supplied) Unraveling the mechanisms underlying early neural differentiation of ESCs is crucial to the cell-based therapies of neurodegenerate diseases. Neural fate acquisition is proposed to be controlled by a “default” mechanism, for which the molecular regulation is not well understood. In this study, we investigated the functional roles of Mediator Med23 in pluripotency and lineage commitment of embryonic stem cells (ESCs). more...

(Submitter supplied) Abstract: Transcription factors (TFs) play key roles in regulating differentiation and function of stem cells, including muscle satellite cells (MuSCs), a resident stem cell population responsible for postnatal regeneration of the skeletal muscle. Sox11 belongs to the Sry-related HMG-box (SOX) family of TFs that play diverse roles in stem cell behavior and tissue specification. Analysis of single-cell RNA-sequencing (scRNA-seq) datasets identify a specific enrichment of Sox11 mRNA in differentiating but not quiescent MuSCs. more...

(Submitter supplied) We previously showed that STAT3 regulates myoblast differentiation in cell culture models, yet its role in adult muscle satellite cells (MuSC) in vivo was less well characterized. When Stat3 was conditionally deleted in MuSC, muscle development and adult MuSC formation were not affected. However, with repeated muscle injuries, the number of the quiescent MuSC in STAT3-null mice decreased and the regeneration was delayed, suggesting defective MuSC maintenance. more...
