Cortical‐Hypothalamic Assembloids Uncover the Cortical Regulation of Hypothalamic Responses to Fatty Acid

open access: yesCell Proliferation, EarlyView.
By assembling cortical‐hypothalamic circuits, we show that cortical input protects hypothalamic neurons from fatty acid‐induced damage, which activates PGC1α to boost mitochondrial function. This reveals a cortico‐hypothalamic axis that defends against metabolic stress.

A Specific tRNA Half, 3'tiRNA‐GlyGCC, Regulates Hypoxic Pulmonary Artery Smooth Muscle Cell Proliferation via Myrf‐Mediated Endoplasmic Reticulum Stress

open access: yesCell Proliferation, EarlyView.
A schematic diagram illustrating how 3′tiRNA‐GlyGCC promotes the endoplasmic reticulum stress (ERS) and proliferation in hypoxic pulmonary artery smooth muscle cells (PASMCs) by inhibiting the expression of myelin regulatory factor (Myrf), ultimately leading to pulmonary hypertension (PH).

Lysine l‐Lactylation: Bridging Metabolism, Chromatin and Disease

open access: yesCell Proliferation, EarlyView.
Enzymatic regulation of KL‐la. The enzymatic regulation of KL‐la involves two distinct pathways for L‐lactate accumulation: intracellular production through glycolysis‐derived pyruvate conversion by lactate dehydrogenase (LDH) or direct cellular uptake via monocarboxylate transporters (MCTs). These L‐lactate pools fuel two distinct lactylation pathways—

Dermatologic Toxicities Associated With Novel Pan‐RAS/RAF Inhibitors

open access: yesJournal of Cutaneous Pathology, EarlyView.
ABSTRACT Background The mitogen‐activated protein kinase (MAPK) pathway plays a key role in cell‐cycle regulation and tumor progression in cancer. Dermatologic toxicities (DTs) to newer pan‐RAS (RMC‐6236) and pan‐RAF (LXH254/naporafenib) inhibitors are emerging.

GCN2 in proteostasis: structural logic, signalling networks and disease

open access: yesThe FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.
