Rag GTPases are cardioprotective by regulating lysosomal function. [PDF]

open access: yes, 2014
The Rag family proteins are Ras-like small GTPases that have a critical role in amino-acid-stimulated mTORC1 activation by recruiting mTORC1 to lysosome.

Lysosome-endosome fusion and lysosome biogenesis [PDF]

open access: yesJournal of Cell Science, 2000
ABSTRACT Recent data both from cell-free experiments and from cultured cells have shown that lysosomes can fuse directly with late endosomes to form a hybrid organelle. This has a led to a hypothesis that dense core lysosomes are in essence storage granules for acid hydrolases and that, when the former fuse with late endosomes, a hybrid ...

Regulators of Lysosome Function and Dynamics in Caenorhabditis elegans

open access: yesG3: Genes, Genomes, Genetics, 2017
Lysosomes, the major membrane-bound degradative organelles, have a multitude of functions in eukaryotic cells. Lysosomes are the terminal compartments in the endocytic pathway, though they display highly dynamic behaviors, fusing with each other and with

Beyond self-eating: The control of nonautophagic functions and signaling pathways by autophagy-related proteins. [PDF]

open access: yes, 2017
The identification of conserved autophagy-related proteins (ATGs) that mediate bulk degradation of cytosolic material laid the foundation for breakthroughs linking autophagy to a litany of physiological processes and disease conditions.

Neuronal lysosomes [PDF]

open access: yesNeuroscience Letters, 2019
Lysosomes support diverse cellular functions by acting as sites of macromolecule degradation and nutrient recycling. The degradative abilities of lysosomes are conferred by a lumen that is characterized by an acidic pH and which contains numerous hydrolases that support the breakdown of major cellular macromolecules to yield cellular building blocks ...

Lysosomal Physiology [PDF]

open access: yesAnnual Review of Physiology, 2015
Lysosomes are acidic compartments filled with more than 60 different types of hydrolases. They mediate the degradation of extracellular particles from endocytosis and of intracellular components from autophagy. The digested products are transported out of the lysosome via specific catabolite exporters or via vesicular membrane trafficking.

Merkel cell polyomavirus large T antigen disrupts lysosome clustering by translocating human Vam6p from the cytoplasm to the nucleus [PDF]

open access: yes, 2011
Merkel cell polyomavirus (MCV) has been recently described as the cause for most human Merkel cell carcinomas. MCV is similar to simian virus 40 (SV40) and encodes a nuclear large T (LT) oncoprotein that is usually mutated to eliminate viral replication ...

Lysosome

open access: yesJournal of Inborn Errors of Metabolism and Screening, 2016
Since Christian de Duve first described the lysosome in the 1950s, it has been generally presented as a membrane-bound compartment containing acid hydrolases that enables the cell to degrade molecules without being digested by autolysis.

Lysosome-mediated processing of chromatin in senescence [PDF]

open access: yes, 2013
Cellular senescence is a stable proliferation arrest, a potent tumor suppressor mechanism, and a likely contributor to tissue aging. Cellular senescence involves extensive cellular remodeling, including of chromatin structure. Autophagy and lysosomes are

Inositol Triphosphate Signaling Triggers Lysosome Biogenesis Via Calcium Release from Endoplasmic Reticulum Stores

open access: yesContact, 2022
Lysosomes serve as cellular degradation and signaling centers that coordinate the turnover of macromolecules with cell metabolism. The adaptation of cellular lysosome content and activity via the induction of lysosome biogenesis is therefore key to cell ...
