Mitochondrial Homeostasis in Pancreatic β Cell Function: Mechanisms and Therapeutic Targets for Diabetes

open access: yesJournal of Diabetes, Volume 18, Issue 5, May 2026.
This review highlights mitochondrial dysfunction as a central driver of pancreatic β cell failure in diabetes, caused by disrupted mitochondrial quality control (MQC), oxidative stress, and impaired organelle communication. Emerging therapies, such as DRAK2 inhibitors and metabolic reprogramming agents, show promise in restoring β cell function by ...

VDAC electronics: 1. VDAC-hexo(gluco)kinase generator of the mitochondrial outer membrane potential

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2014
The simplest mechanism of the generation of the mitochondrial outer membrane potential (OMP) by the VDAC (voltage-dependent anion channel)-hexokinase complex (VHC), suggested earlier, and by the VDAC-glucokinase complex (VGC), was computationally analyzed.

Preoperative Beta‐Hydroxy‐Beta‐Methyl‐Butyrate Supplementation Reduces Mitochondrial Dynamics Proteins and Preserves Hepatic Mitochondrial Function After Partial Hepatectomy in Mice

open access: yesActa Physiologica, Volume 242, Issue 5, May 2026.
ABSTRACT Aim The liver exhibits a remarkable regenerative capacity, enabling this organ to maintain homeostasis even after significant injury. However, hepatic regeneration requires sufficient energy to sustain cellular hypertrophy and proliferation, thus ensuring efficient tissue repair.

Ketamine effect on intracellular and mitochondrial calcium mobilization [PDF]

open access: yes, 2016
The suppressive effects of ketamine on intracellular calcium has been reported in a variety of cells although the mechanisms involved are not well understood.

Nanosilicates Enhanced Periodontal Angiogenesis by Regulating Microtubule Dynamic‐Mediated STAT3 Pathway

open access: yesCell Proliferation, Volume 59, Issue 5, May 2026.
Nanosilicates triggered MAP4‐dependent microtubule remodelling via the ROS/MAPK pathway, shifting microtubules into a dynamic active state, which subsequently promoted activation of the STAT3 pathway, ultimately facilitating periodontal angiogenesis.

Emerging Role of Ferroptosis in Diabetes and Associated Complications: When Metabolic Dysregulation Meets Cell Death

open access: yesCell Proliferation, Volume 59, Issue 5, May 2026.
This study identifies ferroptosis as a key driver of diabetes and its complications via iron metabolism and lipid peroxidation, elucidates organelle interactions underlying cell vulnerability, and provides insights for targeted therapies against metabolic disorders.

Cell‐Type‐Dependent Metabolic Compensation Preserves Photoreceptor Survival Through Pyruvate Kinase Isoform Balance

open access: yesThe FASEB Journal, Volume 40, Issue 7, 15 April 2026.
We investigated the roles of PKM2, PKM1, and LDHA in retinal metabolism and structural integrity. In the normal retina, these enzymes are maintained at defined levels that support photoreceptor function. Rod‐specific deletion of LDHA, alone or with PKM2, caused age‐dependent degeneration, as PKM1 induction did not reach levels comparable to PKM2.

Broad activation of the ubiquitin-proteasome system by Parkin is critical for mitophagy [PDF]

open access: yes, 2011
Parkin, an E3 ubiquitin ligase implicated in Parkinson's disease, promotes degradation of dysfunctional mitochondria by autophagy. Using proteomic and cellular approaches, we show that upon translocation to mitochondria, Parkin activates the ubiquitin ...

Integrins engage mitochondrial function for signal transduction by a mechanism dependent on Rho GTPases. [PDF]

open access: yes, 2002
We show here the transient activation of the small GTPase Rac, followed by a rise in reactive oxygen species (ROS), as necessary early steps in a signal transduction cascade that lead to NFkappaB activation and collagenase-1 (CL-1)/matrix ...

Changes in membrane lipids drive increased endocytosis following Fas ligation [PDF]

open access: yes, 2017
Once activated, some surface receptors promote membrane movements that open new portals of endocytosis, in part to facilitate the internalization of their activated complexes.
