Cell Stress, 2021 Cellular adaptation to stress is a crucial homeostatic process for survival, metabolism, physiology, and disease. Cells respond to stress stimuli (e.g., nutrient starvation, growth factor deprivation, hypoxia, low energy, etc.) by changing the activity ...

mTORC1 maintains metabolic balance [PDF]
Cell Research, 2015 Anticancer therapeutics aimed at the inhibition of mTORC1 activity shift metabolism to favor the degradation of extracellular proteins. Recently Thompson and colleagues demonstrated a novel regulatory mechanism whereby mTORC1 plays a distinct role as a key regulator of metabolism depending on the environmental nutrient status.

Clinical and Experimental Hypertension, 2023 Background In-stent restenosis hardly limits the therapeutic effect of the percutaneous vascular intervention. Although the restenosis is significantly ameliorated after the application of new drug-eluting stents, the incidence of restenosis remains at a

Differential effects of selective inhibitors targeting the PI3K/AKT/mTOR pathway in acute lymphoblastic leukemia [PDF]
, 2013 Purpose: Aberrant PI3K/AKT/mTOR signaling has been linked to oncogenesis and therapy resistance in various malignancies including leukemias. In Philadelphia chromosome (Ph) positive leukemias, activation of PI3K by dysregulated BCR-ABL tyrosine kinase ...

Glutaminolysis Activates Rag-mTORC1 Signaling [PDF]
Molecular Cell, 2012 Amino acids control cell growth via activation of the highly conserved kinase TORC1. Glutamine is a particularly important amino acid in cell growth control and metabolism. However, the role of glutamine in TORC1 activation remains poorly defined. Glutamine is metabolized through glutaminolysis to produce α-ketoglutarate.

PRAS40 suppresses atherogenesis through inhibition of mTORC1-dependent pro-inflammatory signaling in endothelial cells [PDF]
, 2019 Endothelial pro-inflammatory activation plays a pivotal role in atherosclerosis, and many pro-inflammatory and atherogenic signals converge upon mechanistic target of rapamycin (mTOR).

Covalent targeting of the vacuolar H+-ATPase activates autophagy via mTORC1 inhibition. [PDF]
, 2019 Autophagy is a lysosomal degradation pathway that eliminates aggregated proteins and damaged organelles to maintain cellular homeostasis. A major route for activating autophagy involves inhibition of the mTORC1 kinase, but current mTORC1-targeting ...

médecine/sciences, 2013 mTOR (mammalian target of rapamycin), a protein kinase highly conserved, is the catalytic subunit of two complexes, mTORC1 and mTORC2. These complexes are regulated by amino acids availability, by insulin and growth factors signaling pathways. Thus, mTORC1 and mTORC2 complexes are essential sensors of the cellular nutrient and energy levels in living ...

Metabolic signaling directs the reciprocal lineage decisions of αβ and γδ T cells [PDF]
, 2018 Wiring metabolic signaling circuits in thymocytes Cell differentiation is often accompanied by metabolic changes. Yang et al. report that generation of double-positive (DP) thymocytes from double-negative (DN) cells coincides with dynamic regulation of ...

Deletion of Tsc2 in nociceptors reduces target innervation, ion channel expression, and sensitivity to heat [PDF]
, 2018 The mechanistic target of rapamycin complex 1 (mTORC1) is known to regulate cellular growth pathways, and its genetic activation is sufficient to enhance regenerative axon growth following injury to the central or peripheral nervous systems.
