PIKFYVE-dependent regulation of MTORC1 and TFEB
Autophagy Reports, 2022 TFEB (transcription factor EB) is essential for the upregulation of gene expression required for macroautophagy/autophagy and lysosomal function. Under nutrient-rich conditions, TFEB is inactivated by MTOR (mechanistic target of rapamycin kinase) complex

p38 regulates the tumor suppressor PDCD4 via the TSC-mTORC1 pathway
Cell Stress, 2021 Programmed cell death protein 4 (PDCD4) exerts critical functions as tumor suppressor and in immune cells to regulate inflammatory pro-cesses. The phosphoinositide 3-kinase (PI3K) promotes degradation of PDCD4 via mammalian target of rapamycin complex 1 (

Micro(RNA) Managing by mTORC1 [PDF]
Molecular Cell, 2015 In this issue of Molecular Cell, Ye et al. (2015) demonstrate that mTORC1 globally regulates miRNA biogenesis under nutrient-rich conditions via the E3 ubiquitin ligase Mdm2, which promotes Drosha degradation.

A Novel Combination Therapy Approach Targeting STAT3 and Autophagy in Glioblastoma
Autophagy Reports, 2022 The aggressive brain cancer glioblastoma (GBM) is notoriously resistant to radiotherapy and chemotherapy, which drives tumor recurrence and relapse. GBM cells are highly addicted to STAT3 (signal transducer and activator of transcription 3) and STAT3 ...

Cytoprotective Activated Protein C Averts Nlrp3 Inflammasome–Induced Ischemia-Reperfusion Injury Via Mtorc1 Inhibition [PDF]
, 2017 Cytoprotection by activated protein C (aPC) after ischemia-reperfusion injury (IRI) is associated with apoptosis inhibition. However, IRI is hallmarked by inflammation, and hence, cell-death forms disjunct from immunologically silent apoptosis are, in ...

Suppressing mTORC1 on the lysosome [PDF]
The EMBO Journal, 2017 The mechanistic target of rapamycin, mTOR, is a protein kinase that integrates environmental and nutritional inputs into regulation of cell growth and metabolism. Key outputs of mTOR signalling occur from the lysosome membrane in the form of the multi‐subunit mTOR complex 1 (mTORC1), which phosphorylates multiple targets. While class I phosphoinositide

p16: cycling off the beaten path
Molecular & Cellular Oncology, 2019 p16INK4A (hereafter called p16) is a faithful cellular ally in the fight against tumorigenesis. Although its canonical pathway through retinoblastoma (RB) is well delineated, RB-independent functions for p16 are beginning to emerge. Here we summarize non-

RETREG3/FAM134C phosphorylation by CSNK2 regulates reticulophagy during starvation
Autophagy Reports, 2022 Starvation is the most potent physiological inducer of autophagy, the catabolic process which degrades unessential cytosolic components to sustain cellular homeostasis and survival.

Metabolic crosstalk: molecular links between glycogen and lipid metabolism in obesity. [PDF]
, 2014 Glycogen and lipids are major storage forms of energy that are tightly regulated by hormones and metabolic signals. We demonstrate that feeding mice a high-fat diet (HFD) increases hepatic glycogen due to increased expression of the glycogenic ...
