GCN2 in proteostasis: structural logic, signalling networks and disease
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.

Exercise‐related microRNAs cel‐miR‐249‐3p and cel‐miR‐77‐5p in C. elegans regulate lifespan, fitness, mitochondrial morphology and membrane potential. Although lacking direct mammalian orthologs, H2O2‐induced microRNAs mmu‐miR‐181a‐5p and mmu‐miR‐378a‐3p regulate myogenesis, autophagy, mitochondrial content and respiration in murine myoblasts ...

Mitochondria can be transferred from bone marrow cells to cancer cells in acute myeloid leukaemia and multiple myeloma, boosting tumour energy production, growth, and drug resistance. This review highlights key transfer mechanisms and shows how targeting mitochondrial movement and dynamics may offer new therapeutic strategies to limit cancer ...

Proteomic analysis of cellular models of neurodegeneration and mitochondrial dysfunction [PDF]
Mitochondrial dysfunction is thought to contribute to neurodegenerative processes. As an example, dysfunction of complex I of the electron transport chain has been observed in Parkinson’s disease patients and 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine (

Arsenite methyltransferase 3 is required for mitochondrial function and hepatic lipid metabolism
AS3MT is a protein that helps the body process arsenic, a naturally occurring toxin found in water and soil. We discovered it also helps cells make and use energy properly. Without AS3MT, cells' mitochondria do not work well, leading to fatty liver and reduced activity. Increasing AS3MT in liver cells restores energy and protects against arsenic damage,

Long‐read sequencing‐based atlas of tissue‐specific expression of DNM1L transcript variants
Targeted long‐read sequencing resolves full‐length DNM1L (Drp1) isoforms and reveals conserved, tissue‐specific expression patterns across human and mouse tissues. Functional assays show that Drp1 isoforms differ in their ability to drive mitochondrial fission, independent of abundance, with specific exons modulating activity.

Ubiquitin and ubiquitin‐like modifications in the endoplasmic reticulum stress response
Endoplasmic reticulum (ER) stress activates various proteostasis control processes, including the unfolded protein response, ribosome‐associated quality control, and ER‐associated degradation. Ubiquitin and ubiquitin‐like modifications dynamically regulate these processes to determine cell fate, promoting adaptation or inducing cell death.

The Role of Oxidative Stress in Periodontitis
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Analysis of mitochondrial DNA variation in the Egyptian population and its implications for forensic DNA analysis [PDF]
The genetic sequence of human mitochondrial DNA (mtDNA) is of particular interest to forensic investigations involving human identification, as well as population genetics.
