A mTORC1-mediated cyst(e)ine sensing mechanism governing GPX4 synthesis and ferroptosis
Molecular & Cellular Oncology, 2021 Ferroptosis is a cell death mechanism triggered by lipid peroxidation. Our recent study linked cyst(e)ine availability with glutathione peroxidase 4 (GPX4) protein synthesis and ferroptosis mitigation via a Rag-mechanistic target of rapamycin complex 1 ...

RhoA regulates the mechanistic target of rapamycin complex 1 (mTORC1)
The FASEB Journal, 2013 The mTORC1 signaling pathway plays a vital role in integrating signals generated by hormones and nutrients to control cell growth and metabolism. The point of integration of many of the input signals from hormones is the GTPase activating protein complex TSC1/2 that acts to repress the mTORC1‐stimulatory activity of the small GTPase Rheb.

The crosstalk between MYC and mTORC1 during osteoclastogenesis
Frontiers in Cell and Developmental Biology, 2022 Osteoclasts are bone-resorbing cells that undergo extensive changes in morphology throughout their differentiation. Altered osteoclast differentiation and activity lead to changes in pathological bone resorption.

Thioredoxin-1 maintains mechanistic target of rapamycin (mTOR) function during oxidative stress in cardiomyocytes [PDF]
, 2017 Thioredoxin 1 (Trx1) is a 12-kDa oxidoreductase that catalyzes thiol-disulfide exchange reactions to reduce proteins with disulfide bonds. As such, Trx1 helps protect the heart against stresses, such as ischemia and pressure overload.

Mechanistic target of rapamycin (mTOR) signaling genes in decapod crustaceans: cloning and tissue expression of mTOR, Akt, Rheb, and S6 kinase in the green crab, Carcinus maenas, and blackback land crab, Gecarcinus lateralis [PDF]
, 2014 Mechanistic target of rapamycin (mTOR) controls global translation of mRNA into protein by phosphorylating p70 S6 kinase (S6K) and eIF4E-binding protein-1. Akt and Rheb, a GTP-binding protein, regulate mTOR protein kinase activity. Molting in crustaceans
