Fructose-1,6-bisphosphate and aldolase mediate glucose sensing by AMPK [PDF]
葡萄糖是生物中最基本、最主要的营养物质,它不仅是机体能量的主要来源,也是生物质合成的主要原料。因此,葡萄糖的水平对于生物体是极其重要的。然而,在生活中,体内葡萄糖水平的波动是十分常见的,这是因为我们不可能每时每刻都在摄入葡萄糖:睡一大觉、剧烈运动几个小时或者太忙了没时间吃饭,都会引起葡萄糖水平的显著下降。这时,机体能够触发一套有效的过程应对这类“不利情况”,其中最为关键的就是激活“代谢的核心调节”——AMPK。在葡萄糖水平下降时,被激活的AMPK能够迅速启动脂肪、蛋白质的分解代谢,关闭它们的合成代谢 ...

PHGDH is required for germinal center formation and is a therapeutic target in MYC-driven lymphoma.
comprehensive characterization of the role of the serine synthesis pathway in germinal center B cells lymphomas derived from these cells. We demonstrate that upregulation of a functional serine synthesis cell activation the center reaction.

Decoding Key Nodes in the Metabolism of Cancer Cells: Sugar & Spice and All Things Nice [PDF]
In the past 5 years, a convergence of studies has resulted in a broad appreciation in the cancer research community that reprogramming of cellular metabolism may be more central to cancer than appreciated in the past 30 years.

Metabolomic changes during cellular transformation monitored by metabolite-metabolite correlation analysis and correlated with gene expression. [PDF]
To investigate metabolic changes during cellular transformation, we used a 1H NMR based metabolite-metabolite correlation analysis (MMCA) method, which permits analysis of homeostatic mechanisms in cells at the steady state, in an inducible cell ...

Therapeutic arginine starvation in ASS1-deficient cancers inhibits the Warburg effect
Argininosuccinate Synthetase 1 deficiency induces dependence on extracellular arginine for continued cellular growth and survival. Arginine starvation inhibits the Warburg effect and diverts glucose into serine biosynthesis, while simultaneously ...

Local lung hypoxia determines epithelial fate decisions during alveolar regeneration. [PDF]
After influenza infection, lineage-negative epithelial progenitors (LNEPs) exhibit a binary response to reconstitute epithelial barriers: activating a Notch-dependent ΔNp63/cytokeratin 5 (Krt5) remodelling program or differentiating into alveolar type II
