The complexities of respiratory chain biogenesis and maintenance in yeast mitochondria
Protein Science, Volume 35, Issue 4, April 2026.Abstract Mitochondrial oxidative phosphorylation is the most efficient way of energy conversion for eukaryotic cells. It is executed by a series of high‐molecular weight enzyme complexes in the inner mitochondrial membrane that were acquired during endosymbiosis at the root of eukaryotic evolution.

Prohibitin 1 modulates mitochondrial function of Stat3 [PDF]
Cellular Signalling, 2014 Mitochondrial dysfunction in intestinal epithelial cells (IEC) is thought to precede the onset of inflammatory bowel diseases (IBD). Expression of Prohibitin 1 (PHB), a mitochondrial protein required for optimal electron transport chain (ETC) activity, is decreased in mucosal biopsies during active and inactive IBD.

Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants
Advanced Science, Volume 13, Issue 14, 9 March 2026.In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium

Advanced Science, Volume 13, Issue 16, 18 March 2026.Metastatic invasion emerges when tumor‐intrinsic programs and microenvironmental forces converge on mitochondrial quality control. A context‐stratified framework links mtROS, mtDNA integrity, mechanics and nutrient/oxygen cues to fission–fusion remodeling, mtUPR and mitophagy.

The prohibitin-binding compound fluorizoline induces apoptosis in chronic lymphocytic leukemia cells through the upregulation of NOXA and synergizes with ibrutinib, 5-aminoimidazole-4-carboxamide riboside or venetoclax [PDF]
, 2018 Fluorizoline is a new synthetic molecule that induces apoptosis by selectively targeting prohibitins. In the study herein, the pro-apoptotic effect of fluorizoline was assessed in 34 primary samples from patients with chronic lymphocytic leukemia ...

“Prohibitin”g CRAF/MAPK Activation with Rocaglamides
Chemistry & Biology, 2012 Interaction with prohibitin (PHB) is required for full activation of CRAF kinase, the central member of the highly conserved RAS-CRAF-MAPK pathway. In this issue of Chemistry & Biology, Polier et al. show that the natural anti-tumor compounds rocaglamides target the CRAF-PHB interaction to disrupt the MAPK pathway leading to proliferation block in ...

MedComm – Oncology, Volume 5, Issue 1, March 2026.Ageing acts as a double‐edged sword in cancer. In the elderly, open chromatin, immunosenescence, and chronic inflammation drive SASP (IL‐6, MMPs), MDSC accumulation and T‐cell suppression, fostering tumor‐promoting microenvironments and limited therapeutic benefit.
