ATF4–histone 2‐hydroxyisobutyrylation feedback loop drives sepsis‐induced inflammation
Background and Purpose The role and mechanisms of lysine 2‐hydroxyisobutyrylation (Khib) in the acute inflammatory phase of sepsis remain unclear. We investigated the function and underlying

Targeting ATF4 alters SOD1 aggregation in mutant SOD1 transgenic mice.
Histological characterization of ATF4−/−/SOD1G86R spinal cord. (A) Immunofluorescence analysis of NeuN and Olig2 staining in spinal cord tissue derived from ATF4+/+, ATF4+/+/SOD1G86R and ATF4−/−/SOD1G86R at the late disease stage.

Proteostasis in the regulation of pancreatic islet cell plasticity
Adaptive proteostasis integrates protein synthesis, folding, trafficking, and degradation through ISR, UPR, ER stress responses, autophagy, and proteasomal degradation. In pancreatic islet cells, this coordinated network preserves protein quality, secretory function, proliferation, and survival, enabling adaptation to metabolic stress and aging while ...

ATF4 transcriptional activities during UPR are Siah1/2-dependent.
(A) Siah2 expression augments ATF4 protein levels. WT MEFs were transfected either with control or Siah2 expression vectors, and 24 h later the cells were collected. Harvested proteins were analyzed for ATF4, Siah2 and β-actin.

One day of environment‐induced heat stress causes injury to the murine kidney
Abstract Environment‐induced heat stress (EIHS) results from sustained body temperature elevation owing to prolonged exposure to heat and humidity. We hypothesized that EIHS would cause kidney injury and cellular dysfunction. To test this hypothesis, female C57 mice were exposed to EIHS (n = 14; 37.6°C, 42.0% relative humidity) or thermoneutral (TN ...

Abstract Venetoclax combined with hypomethylating agents has improved treatment for older or unfit patients with acute myeloid leukaemia (AML), but resistance and relapse remain common. This review analyses the rationale for combining venetoclax with inhibitors of histone deacetylase (HDAC).

Cells adapt to proteostatic and metabolic stresses, in part, through stress activated eIF2α kinases that stimulate the translation of ATF4. Stress-induced ATF4 translation is regulated through elements at ATF4 mRNA’s 5’ leader.

Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.
