Organs age at different rates, yet the protective mechanisms contributing to decelerated aging in certain tissues remain unclear. Applying cross-tissue comparisons to molecular readouts of aging, here we report that the intervertebral disc (IVD) ages …
This review examines how C. elegans worms switch their mitochondrial energy-production machinery to survive low-oxygen or toxic conditions, and how mild damage to this system can actually extend lifespan. The findings suggest conserved cellular stress-response …
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 …
Methionine restriction (MR) extends the lifespan and healthspan of numerous eukaryotic organisms, but the molecular mechanisms at play are unclear. Here we find that the ability of MR to extend the budding yeast chronological 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 …
Ribosomes consist of approximately 80 distinct ribosomal proteins and rRNA. The genes encoding these ribosomal components are among the most highly expressed in growing cells. Changes in ribosome composition, such as those induced by oxidative …
Researchers found that corylin, a flavonoid from a traditional medicinal plant, extended lifespan and improved stress resistance in C. elegans worms by activating two key proteins that enhance cellular housekeeping and mitochondrial health. While promising, …
Centrosome amplification is frequently associated with chromosomal instability and tumor progression, but how cells coordinate centriole assembly with the control of centrosome numbers and quality remains poorly understood. TIAM1 is a RAC1 guanine nucleotide exchange …
During mitotic growth, Saccharomyces cerevisiae cells age by dividing asymmetrically producing young daughter cells while retaining age-associated damage in the mother cell, which will eventually become senescent. Gametogenesis naturally and completely resets precursor cell lifespan, …
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 …
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 …
Researchers reviewed how people who live to 100+ maintain surprisingly youthful immune function despite extreme age, resisting the chronic inflammation and immune decline that typically accompany aging. They identified several biological mechanisms—including controlled inflammatory pathways, …
Lysosomal dysfunction is a prominent feature of neurodegeneration and aging, yet how primary defects in lysosomal trafficking are converted into progressive cellular decline remains poorly understood. Niemann Pick disease type C (NPC), caused by impaired …
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. …
This review examines cellular senescence (aging cells that stop dividing) in muscle regeneration, finding that senescent cells play a dual role: they can briefly help repair muscle after injury, but when they accumulate in aging …
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 …
This review examines how lysosomes—cellular recycling centers—actively regulate aging through two newly discovered signaling pathways (lysosomal surveillance response and transgenerational lysosomal signaling) and the protein TFEB. These findings suggest targeting lysosomal activity could be a …
PURPOSE: Apigenin, is a plant derived flavone found in parsley, celery and some spices. It has fascinated a lot of researchers because of its anti-viral, anti-bacterial, anti-inflammatory and above all its anti-cancer abilities. This review …
Aging is characterized by progressive loss of proteostasis, and heat shock transcription factor 1 (HSF1) is the master regulator of the cellular stress response, making it an attractive pharmacological target for interventions aimed at extending …
