The role of the nucleus in the control of mitochondrial precursor proteins in yeast. [PDF]
Abstract Mitochondria are essential organelles of eukaryotic cells, with vital roles in energy production, biosynthesis of macromolecules, and intracellular signaling. Their function depends on a complex proteome with proteins targeted to different mitochondrial sub‐compartments.

HSF1–DBC1 axis drives prostate cancer progression by activating a metastatic transcriptional program [PDF]
Heat shock factor 1 (HSF1) is a key stress-protective transcription factor that acts as a guardian of proteostasis. HSF1 also plays multifaceted roles in tumor-associated processes including proliferation and metastasis.

Holding but not folding: How a single charge flip uncouples the DNAJC7-Hsp70 relay in amyotrophic lateral sclerosis. [PDF]
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.

Lactobacillus paracasei L9 Ameliorates Pulmonary Fibrosis in Aged Mice via Gut-Lung Axis-Mediated Regulation of Immune Cell Migration. [PDF]
Oral administration of Lactobacillus paracasei L9 (L9) reshapes the gut microbiota, specifically increasing the abundance of short‐chain fatty acid (SCFA)‐producing bacteria (e.g., Blautia), thereby leading to a significant elevation of serum propionic acid (97% increase) and butyric acid (193% increase).

HSF1: Primary Factor in Molecular Chaperone Expression and a Major Contributor to Cancer Morbidity
Heat shock factor 1 (HSF1) is the primary component for initiation of the powerful heat shock response (HSR) in eukaryotes. The HSR is an evolutionarily conserved mechanism for responding to proteotoxic stress and involves the rapid expression of heat ...

HSF1 protects cells from cadmium toxicity by governing proteome integrity
Background: Cadmium toxicity has been associated with disruption of protein homeostasis by interfering with protein folding processes. Heat shock factor 1 (HSF1) coordinates the rapid and extensive cellular response to maintain proteomic balance facing ...

Loss of heat shock factor 1 promotes hepatic stellate cell activation and drives liver fibrosis
Liver fibrosis is an aberrant wound healing response that results from chronic injury and is mediated by hepatocellular death and activation of hepatic stellate cells (HSCs).
