Tinnitus involves peripheral auditory damage and aberrant central plasticity, with dysregulated BDNF signaling linking injury to compensation. Yet, direct evidence connecting BDNF/AKT/mTOR pathway activation to behavioral phenotypes is limited. This study examined BDNF/AKT/mTOR expression in …
Skin aging is a multifactorial, dynamically regulated biological process modulated by the synergistic interplay of intrinsic genetic programming and extrinsic environmental stressors. Chronological skin aging is dominated by molecular signatures such as telomere attrition, mitochondrial …
Aortic dissection (AD) is a catastrophic cardiovascular syndrome with an in-hospital mortality of more than 90%. We previously identified oxidative inactivation of sarcoplasmic/endoplasmic reticulum Ca2+-ATPase 2 (SERCA2) at cysteine 674 (C674) as a driver of …
Resistance to therapeutic agents represents a critical barrier in the clinical management of triple-negative breast cancer (TNBC), necessitating novel therapeutic strategies. We discovered that mammalian target of rapamycin (mTOR) and glutaminase 1 (GLS1) mediated glutamine …
Disulfidptosis, a recently identified form of regulated cell death driven by toxic intracellular disulfide accumulation and subsequent collapse of the actin cytoskeleton, represents a promising therapeutic vulnerability in hepatocellular carcinoma (HCC), particularly for tumors exhibiting …
Given the involvement of long non-coding RNA-differentiation antagonizing non-protein coding RNA (lncRNA DANCR) in osteoporosis (OP), this study aimed to investigate its role in osteogenic differentiation (OD) of bone marrow mesenchymal stem cells (BMSCs) and …
Tauopathies are neurodegenerative diseases characterized by the presence of hyperphosphorylated tau (p-tau) and neurofibrillary tangles. Autophagy is a critical self-degradation mechanism that preserves cellular homeostasis and function, including the clearance of misfolded proteins. Autophagy is …
Cerebral amyloid angiopathy (CAA) is characterized by the deposition of amyloid {beta} fibrils (A{beta}) within walls of the cerebrovasculature and contributes to intracerebral hemorrhage, ischemic stroke, and cognitive dysfunction in patients with Alzheimers disease (AD) …
The health risks of polypropylene plastic, a major food-grade polymer, are often underestimated. Current evidence indicates that infants and young children may ingest millions of polypropylene microplastic particles (PP-MPs) daily, accompanied by co-exposure to di(2-ethylhexyl) …
Multiple sclerosis (MS) is a chronic autoimmune disease characterized by demyelination, neuroinflammation, and progressive neurodegeneration. The mechanistic target of rapamycin (mTOR) pathway plays a key role in regulating immune responses, cell metabolism, autophagy, and repair …
BACKGROUND: Diabetic kidney disease (DKD) is a leading cause of end-stage renal disease, with proximal tubule fibrosis being a key pathological feature. Our previous study identified significant upregulation of cytosolic nonspecific dipeptidase 2 (CNDP2) in …
AIMS: Numerous preclinical studies suggested that targeted inhibition of mammalian target of rapamycin (mTOR) may be beneficial for the treatment of osteoporosis. However, the relevance of these findings to human populations remains unclear. We hypothesized …
Homeobox C9 (HOXC9) is aberrantly expressed in multiple malignancies; however, its functional role in esophageal squamous cell carcinoma (ESCC) remains elusive. This study investigated the expression, function, and underlying molecular mechanisms of HOXC9 in ESCC. …
Cellular metabolism is precisely regulated in response to nutrient availability. As an extremely energy-consuming anabolic process, ribosome biogenesis should be tightly controlled in response to nutrient supply. However, how the nucleolus responds to different nutrient …
Non-small cell lung cancer (NSCLC) remains a leading cause of cancer-related deaths worldwide, highlighting the urgent requirement for innovative therapeutic strategies. Cytisine N-methylene-(4',5,7-trihydroxy)-isoflavone (named CNI3), a natural derivative of cytisine N-isoflavone isolated from Sophora alopecuroides …
Researchers found that a protein called pitp-1 acts as a brake on longevity by activating mTOR signaling—a key aging pathway. Disabling pitp-1 in neurons extended lifespan, improved muscle function, and boosted stress resistance in C. …
Adult stem cells are essential for maintaining tissue homeostasis and facilitating tissue repair. The ability of aged stem cells to generate functional progeny declines, which is closely associated with the onset and progression of age-related …
Biallelic pathogenic variants in STRADA (STE20-related adaptor alpha), an upstream regulator of the mechanistic target of rapamycin (mTOR) pathway, result in megalencephaly, drug-resistant epilepsy, and severe intellectual disability. This study explores how mTOR pathway hyperactivity …
Researchers gave aging mice rapamycin and found it prevented the normal decline in movement and motor control, with females benefiting more than males. The benefits appear linked to reduced oxidative stress and cellular stress in …
Despite multiple therapeutic strategies, a significant proportion of psoriatic patients fail to achieve complete/sustained disease clearance, highlighting the need for effective adjuvant or alternative therapy. Melittin, the main component in bee venom, exhibits valuable anti-inflammatory …
