Mitochondria are complex organelles critical to the maintenance of cellular homeostasis. Central to this regulation are Prohibitins (PHBs), a novel set of proteins involved in several mitochondrial quality control pathways, including protein folding, biogenesis, and mitophagy. PHBs mediate various cellular responses including cell survival and myogenesis, suggesting that their roles are intricate and multifaceted. While evidence suggests that PHBs facilitate mitochondrial homeostasis, their exact mechanism of action remains unclear. Elucidating the precise mechanisms driving PHB-mediated adaptations will ultimately enable the development of therapeutic strategies aimed towards the treatment of age-related diseases, characterized by mitochondrial perturbations.

This review comprehensively summarizes the current understanding of ubiquitin-specific protease 30 (USP30), covering its structural characteristics, functions in cellular processes, associations with diseases, diagnostic and therapeutic strategies, as well as controversies and future perspectives. USP30, a deubiquitinating enzyme, plays crucial roles in mitochondrial quality control, autophagy regulation, and cellular homeostasis. It is implicated in the progression of several malignancies, including hepatocellular carcinoma, breast carcinoma, and glioblastoma, as well as neurodegenerative disorders such as Parkinson's disease.

Sciatica, often resulting from lumbar disc herniation or nerve compression, disrupts electrical signal transmission, leading to muscle atrophy, mitochondrial dysfunction, and impaired energy metabolism. This study explored the therapeutic effects of Fu's subcutaneous needling (FSN) in a chronic constriction injury (CCI) rat model, assessing its impact on neuropathic pain, muscle mass, and structural integrity. Histological and ultrastructural analyses demonstrated that FSN alleviated hypersensitivity, reduced muscle atrophy, preserved mitochondrial density, and maintained glycogen storage.

Diabetic foot ulcers (DFUs) are a serious complication of diabetes, characterized by delayed wound healing, recurrent infection, and risk of amputation. Mitochondrial dysfunction has emerged as a central pathological mechanism underlying impaired wound healing. Persistent hyperglycemia triggers a cascade of mitochondrial abnormalities like disrupted calcium homeostasis, excessive ROS production, impaired autophagy, increased apoptosis, and imbalanced mitochondrial dynamics.

Background: After spinal cord injury (SCI), pro-inflammatory microglia accumulate and impede axonal regeneration. We explored whether secreted protein acidic and rich in cysteine (Sparc) restrains microglial inflammation and fosters neurite outgrowth.
Methods: Mouse microglial BV2 cells were polarized to a pro-inflammatory phenotype with lipopolysaccharides (LPSs).

Sarcopenia is the progressive loss of skeletal muscle mass, strength, and function, significantly contributing to frailty, disability, and mortality in aging populations. As life expectancy rises, sarcopenia presents a growing public health challenge, increasing healthcare costs, and diminishing quality of life. Despite its prevalence, sarcopenia is often underdiagnosed due to limitations in current diagnostic tools, including the lack of standardized cut-off values and reliance on physical performance tests.
