COVID 19 in a family with rare genetic disease of the nervous system

Неврология, нейропсихиатрия, психосоматика, 2022
We present familial tuberous sclerosis (TS) case complicated by COVID-19. COVID-19 aggravates the course of TS and may lead to a fatal outcome. We review the role of mTORC1 (mechanistic/mammalian Target of Rapamycin Complex 1) in the development and ...

Cellular Uptake, Metabolism and Sensing of Long-Chain Fatty Acids

Frontiers in Bioscience-Landmark, 2023
Fatty acids (FAs) are critical nutrients that regulate an organism’s health and development in mammal. Long-chain fatty acids (LCFAs) can be divided into saturated and unsaturated fatty acids, depending on whether the carbon chain contains at least 1 ...

Osteocyte TSC1 promotes sclerostin secretion to restrain osteogenesis in mice [PDF]

Open Biology, 2019
Osteocytes secrete the glycoprotein sclerostin to inhibit bone formation by osteoblasts, but how sclerostin production is regulated in osteocytes remains unclear.

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 ...

Nuclear receptor subfamily 1 group D member 1 suppresses the proliferation, migration of adventitial fibroblasts, and vascular intimal hyperplasia via mammalian target of rapamycin complex 1/β-catenin pathway

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

Survival of intracellular pathogens in response to mTORC1- or TRPML1-TFEB-induced xenophagy

Autophagy Reports, 2023
Intracellular pathogens establish persistent infections by generating reservoirs that protect them from the action of antibiotics and the host immune response.

GRASPing the unconventional secretory machinery to bridge cellular stress signaling to the extracellular proteome

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 ...

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 ...

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 ...

Metformin alters signaling induced crosstalk and homeostasis in the carcinogenesis paradigm “Epistemology of the origin of cancer”

4 open, 2019
The anti-hyperglycemic drug, Metformin, is effective in treating early stages of diabetes and has been associated with a 37% decrease in cancer incidence. While the precise mechanisms for the anti-cancer effects of Metformin remain to be elucidated, this
