The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
FEBS Letters, EarlyView.This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Conserved regulation of autophagosome-lysosome fusion through YKT6 phosphorylation
Autophagy Reports, 2023 YKT6 is a SNARE (Soluble N-ethylmaleimide-Sensitive Fusion Protein Attachment Protein Receptor) protein governing membrane fusion events of several cellular organelles.

Molecular Oncology, EarlyView.Here, we demonstrate that HS1BP3 interacts with Cortactin through a proline‐rich region (PRR3.1) and show that this interaction, and HS1BP3 itself, promote cancer cell proliferation and invasion. Inhibition of this interaction leads to build‐up of TKS5 in multivesicular endosomes and altered secretion of CD63 and CD9, providing an explanation for the ...

Assays to Monitor Autophagy in Saccharomyces cerevisiae
Cells, 2017 Autophagy is an intracellular process responsible for the degradation and recycling of cytoplasmic components. It selectively removes harmful cellular material and enables the cell to survive starvation by mobilizing nutrients via the bulk degradation of

Membrane Contact Sites in Autophagy
Cells, 2022 Eukaryotes utilize different communication strategies to coordinate processes between different cellular compartments either indirectly, through vesicular transport, or directly, via membrane contact sites (MCSs).

A novel autophagy inhibitor, bTBT, disturbs autophagosome formation
, 2023 Macroautophagy (hereafter, autophagy) is a form of intracellular degradation in which autophagosome formation is systematically coordinated by multiple processes involving numerous autophagy-related gene (ATG) proteins. Autophagy-modulating compounds are

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization
Molecular Oncology, EarlyView.In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

The critical role of dysregulated autophagy in the progression of diabetic kidney disease
Frontiers in Pharmacology, 2022 Diabetic kidney disease (DKD) is one of the major public health problems in society today. It is a renal complication caused by diabetes mellitus with predominantly microangiopathy and is a major cause of end-stage renal disease (ESRD).
