OncoVV‑shHSP70, a vaccinia virus silencing HSP70, demonstrated potent antitumor efficacy in colorectal cancer cell lines, as well as in syngeneic, xenograft, and humanized mouse models. In cell lines, oncoVV‑shHSP70 promoted viral oncolysis and cytokine production through a self‑reinforcing cycle of ROS‑autophagy. In both CT26 and SW620‑humanized mouse

The endoplasmic reticulum membrane protein complex (EMC) is an evolutionarily conserved, multi‐subunit transmembrane protein complex crucial to membrane protein biogenesis and cellular protein quality control. This review systematically examines the structure, functions and disease‐associated regulatory mechanisms of EMC across multiple organ systems ...

Novel curcumin‐derived M4 binds HSP70's ATPase domain, disrupting HSP70‐mediated lysosomes‐autophagy pathway to inhibit TNBC growth and metastasis, and synergizes with paclitaxel for potent combination therapy. ABSTRACT Structural modification of curcumin yielded a novel series of 1,4‐pentadien‐3‐one oxime ether derivatives, among which compound M4 ...

The ribosome‐associated complex regulates cytosolic translation upon mitoprotein‐induced stress
Defects in mitochondrial protein import trigger a stress response. The contribution of translation regulation to such a response is only partially understood. We demonstrate that the deletion of mitochondrial surface proteins (TOM70/TOM71) leads to defects in mitochondrial biogenesis and slow growth.

The ALS‐associated E425K mutation uncouples DNAJC7 from the Hsp70 chaperone cycle
DNAJC7 is a J‐domain protein that plays a key role in protein quality control by regulating Hsp70 activity and preventing protein aggregation. We find that the ALS‐associated E425K mutation in DNAJC7 disrupts productive interaction and activation of Hsp70, thereby blocking the transfer and refolding of client proteins such as TDP‐43.

Here, we report the role of extracellular vesicles (EVs) released from melanoma cells constitutively expressing MHC class II in the regulation of immune cell functions and melanoma metastasis. In particular, we observed an increased localization of HLA‐DRα, CAM receptors, PD‐L1, and STAT3 signaling proteins in the EVs.

Proteostasis ensures proper protein folding, modification, and degradation, while its impairment triggers ER stress. Chronic ER stress and maladaptive UPR via the CHOP–ERO1 axis remodel ERMCs, altering calcium signaling and mitochondrial metabolism.

Proteostasis of organelles in aging and disease
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

In this issue, Elmaleh et al. demonstrate that the E425K mutation in DNAJC7, associated with amyotrophic lateral sclerosis, selectively abolishes one of a co‐chaperone's dual functions. High‐resolution NMR confirmed that the mutation leaves the protein's structure intact while paralyzing its communication with the Hsp70 machinery.
