New insights into tuberous sclerosis complex: from structure to pathogenesis
Frontiers in Cell and Developmental BiologyTuberous sclerosis complex is a genetic disorder characterised by the formation of benign tumours in multiple organs, primarily due to pathogenic variants in the TSC1 and TSC2 tumour suppressor genes. These genes encode hamartin and tuberin, respectively,

Lysosomal Regulation of mTORC1 by Amino Acids in Mammalian Cells
Biomolecules, 2017 The mechanistic target of rapamycin complex 1 (mTORC1) is a master regulator of cell growth in eukaryotic cells. The active mTORC1 promotes cellular anabolic processes including protein, pyrimidine, and lipid biosynthesis, and inhibits catabolic ...

Frontiers in Molecular Biosciences, 2022 Rapamycin is an immunosuppressant macrolide that exhibits anti-proliferative properties through inhibiting the mTOR kinase. In fact, the drug first associates with the FKBP12 enzyme before interacting with the FRB domain of its target.

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).

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer
Molecular Oncology, EarlyView.PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

Implication of mTOR Signaling in NSCLC: Mechanisms and Therapeutic Perspectives
Cells, 2023 Mechanistic target of the rapamycin (mTOR) signaling pathway represents a central cellular kinase that controls cell survival and metabolism. Increased mTOR activation, along with upregulation of respective upstream and downstream signaling components ...

A rapamycin-sensitive signaling pathway contributes to long-term synaptic plasticity in the hippocampus [PDF]
, 2002 Many forms of long-lasting behavioral and synaptic plasticity require the synthesis of new proteins. For example, long-term potentiation (LTIP) that endures for more than an hour requires both transcription and translation.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Evidence that hematopoietic stem cell function is preserved during aging in long-lived S6K1 mutant mice [PDF]
, 2016 The mechanistic target of rapamycin (mTOR) signalling pathway plays a highly conserved role in aging; mice lacking ribosomal protein S6 kinase 1 (S6K1-/-) have extended lifespan and healthspan relative to wild type (WT) controls. Exactly how reduced mTOR
