Transcription Factor Antagonism Controls Enteroendocrine Cell Specification from Intestinal Stem Cells

Scientific Reports, 2017
The balanced maintenance and differentiation of local stem cells is required for Homeostatic renewal of tissues. In the Drosophila midgut, the transcription factor Escargot (Esg) maintains undifferentiated states in intestinal stem cells, whereas the ...

Escargot Restricts Niche Cell to Stem Cell Conversion in the Drosophila Testis

Cell Reports, 2014
Stem cells reside within specialized microenvironments, or niches, that control many aspects of stem cell behavior. Somatic hub cells in the Drosophila testis regulate the behavior of cyst stem cells (CySCs) and germline stem cells (GSCs) and are a ...

BTB-Zinc Finger Oncogenes Are Required for Ras and Notch-Driven Tumorigenesis in Drosophila. [PDF]

PLoS ONE, 2015
During tumorigenesis, pathways that promote the epithelial-to-mesenchymal transition (EMT) can both facilitate metastasis and endow tumor cells with cancer stem cell properties.

NNMT Orchestrates Metabolic‐Epigenetic Reprogramming to Drive Macrophage‐Myofibroblast Transition in Hypertrophic Scarring

Advanced Science, EarlyView.
In macrophage‐myofibroblast transition, upregulated NNMT depletes S‐Adenosylmethionine‌ (SAM) and nicotinamide adenine dinucleotide(NAD+), thereby triggering epigenetic reprogramming via Histone H3 Lysine 27 acetylation (H3K27ac) accumulation at the promoter region of master transcription factor Prrx1.

YKT6 Promotes Bladder Cancer Progression by Stabilizing β‐catenin Through USP7‐Mediated Deubiquitination

Advanced Science, EarlyView.
The SNARE protein YKT6 is upregulated in bladder cancer (BLCA), correlating with poor prognosis. YKT6 promotes tumor proliferation and metastasis by activating Wnt/β‐catenin signaling. It recruits Ubiquitin‐Specific Peptidase 7 (USP7) to deubiquitinate and stabilize β‐catenin, enhancing its nuclear accumulation and driving oncogenic gene expression ...

METTL1‐Mediated M7G tRNA Modification Promotes Residual Liver Regeneration After Hepatectomy via Translational Control

Advanced Science, EarlyView.
METTL1 and its mediated m7G tRNA modification are significantly up‐regulated after partial hepatectomy (PHx). Overexpression of METTL1 improves the efficiency of liver regeneration after PHx, increases the proliferation of hepatocytes, and accelerates the recovery of liver function.

Nuclear Factor I‐B Delays Liver Fibrosis by Inhibiting Chemokine Ligand 5 Transcription

Advanced Science, EarlyView.
This study identifies the transcription factor Nuclear Factor I‐B (NFIB) as a key suppressor of liver fibrosis. NFIB expression declines during hepatic stellate cell activation, and its overexpression reduces fibrosis in mice models. The mechanism involves NFIB directly repressing chemokine C─C motif ligand 5 (CCL5), thereby alleviating oxidative ...

Elemene Augments the Effects of Anti‐PD‐1 Immunotherapy on Hepatocellular Carcinoma by Regulating the miR‐130a‐5p/SPP/MHC‐I Axis

Advanced Science, EarlyView.
Elemene increases SPP expression by competitively binding with miR‐130a‐5p to suppress SPP mRNA degradation. This led to more antigen/MHC‐I complexes being expressed on the cell surface, which consequently facilitated the recognition and killing of HCC cells by CTLs and enhancing the antitumor immune efficacy of anti‐PD‐1.
