Prohibitins are ubiquitous, evolutionarily conserved proteins that are mainly localized in mitochondria. The mitochondrial prohibitin complex comprises two subunits, PHB1 and PHB2. These two proteins assemble into a ring-like macromolecular structure at the inner mitochondrial membrane and are implicated in diverse cellular processes: from mitochondrial biogenesis and function to cell death and...
BACKGROUND Identifying novel tumor biomarkers to develop more effective diagnostic and therapeutic strategies for patients with ACC is urgently needed. The aim of the study was to compare the proteomic profiles between adrenocortical carcinomas (ACC) and normal adrenocortical tissues in order to identify novel potential biomarkers for ACC. METHODS The protein samples from 12 ACC tissues and t...
Prohibitin ring complexes in the mitochondrial inner membrane regulate cell proliferation as well as the dynamics and function of mitochondria. Although prohibitins are essential in higher eukaryotes, prohibitin-deficient yeast cells are viable and exhibit a reduced replicative life span. Here, we define the genetic interactome of prohibitins in yeast using synthetic genetic arrays, and identif...
Autophagic responses specific for damaged or superfluous mitochondria are crucial for the maintenance of cellular and organismal homeostasis. Recent data demonstrate that components of the inner mitochondrial membrane that are unmasked upon outer membrane permeabilization facilitate the autophagic destruction of the organelle.
prohibitins are chaperone proteins highly conserved among eukaryotes. many different functions have been attributed to prohibitins depending on their tissue expression and sub-cellular localization. prohibitins play a major role in mitochondrial physiology, regulating the stability and the processing of both respiratory chain complex subunits and opa1, a mitochondrial fusion regulating protein....
Expression of prohibitin 1 (PHB), a multi-functional protein in the cell, is decreased during inflammatory bowel disease (IBD). Little is known regarding the regulation and role of PHB during intestinal inflammation. We examined the effect of tumor necrosis factor alpha (TNF), a cytokine that plays a central role in the pathogenesis of IBD, on PHB expression and the effect of sustained PHB exp...
Proteolytic cleavage of the dynamin-like guanosine triphosphatase OPA1 in mitochondria is emerging as a central regulatory hub that determines mitochondrial morphology under stress and in disease. Stress-induced OPA1 processing by OMA1 triggersmitochondrial fragmentation, which is associated with mitophagy and apoptosis in vitro. Here, we identify OMA1 as a critical regulator of neuronal surviv...
