O-GlcNAc transferase inhibits visceral fat lipolysis and promotes diet-induced obesity
Nature Communications, 2020 Post-translational O-linked β-N acetylglucosamine (O-GlcNAc) modification acts as a nutrient-sensing mechanism. Here the authors report that O-GlcNAc transferase inhibits adipose tissue lipolysis via O-GlcNAcylation of the lipid droplet protein perilipin

Protective effect of stromal Dickkopf-3 in prostate cancer: opposing roles for TGFBI and ECM-1 [PDF]
, 2018 Aberrant transforming growth factor–β (TGF-β) signaling is a hallmark of the stromal microenvironment in cancer. Dickkopf-3 (Dkk-3), shown to inhibit TGF-β signaling, is downregulated in prostate cancer and upregulated in the stroma in benign prostatic ...

KMT2A promotes melanoma cell growth by targeting hTERT signaling pathway. [PDF]
, 2017 Melanoma is an aggressive cutaneous malignancy, illuminating the exact mechanisms and finding novel therapeutic targets are urgently needed. In this study, we identified KMT2A as a potential target, which promoted the growth of human melanoma cells ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

RASGRP4 is a key factor in the KRAS activation mediated by SOS in tumor Y1 adrenocortical cell lines
Scientific ReportsThe Y1 mouse adrenocortical carcinoma cell line presents amplification of the KRas oncogene and high-basal levels of KRAS-GTP mediated by the GEF SOS. In this research, we developed a dynamic model based on ordinary differential equations of the KRAS-GTP

Mutual inhibition between PTEN and PIP3 generates bistability for polarity in motile cells
Nature Communications, 2018 PIP3 and its phosphatase (PTEN) are enriched mutually exclusively on the anterior and posterior membranes of eukaryotic motile cells. Here authors manipulate PIP3 level and use single-molecule imaging to show that PIP3 suppresses the membrane ...

Glucose deprivation activates a metabolic and signaling amplification loop leading to cell death. [PDF]
, 2012 The altered metabolism of cancer can render cells dependent on the availability of metabolic substrates for viability. Investigating the signaling mechanisms underlying cell death in cells dependent upon glucose for survival, we demonstrate that glucose ...
