Osteoarthritis (OA) is an age-related cartilage degenerative disease, and chondrocyte senescence has been extensively studied in recent years. Increased numbers of senescent chondrocytes are found OA cartilage. Selective clearance a post-traumatic osteoarthritis (PTOA) mouse model ameliorated development, while intraarticular injection cells induced OA. However, the means extent to which affects remain unclear. Here, we review latent mechanism propose potential therapeutic methods target OA-related senescence, with emphasis on immunotherapies. Natural killer (NK) participate elimination multiple organs. A relatively comprehensive discussion presented that section. Risk factors for ageing, obesity, metabolic disorders mechanical overload. Determining relationship between known risk will help elucidate pathogenesis identify optimal treatments.

Abstract Mitochondria play an important role in maintaining cardiac homeostasis by supplying the major energy required for excitation–contraction coupling as well controlling key intracellular survival and death pathways. Healthy mitochondria generate ATP molecules through aerobic process known oxidative phosphorylation (OXPHOS). Mitochondrial injury during myocardial infarction (MI) impairs OXPHOS results excessive production of reactive oxygen species (ROS), bioenergetic insufficiency, contributes to development cardiovascular diseases. Therefore, mitochondrial biogenesis along with proper quality control machinery, which removes unhealthy is pivotal health. Upon damage network, components are recruited segregate target aberrant proteins degradation elimination.

Here, we provide overview recent studies describing mechanistic pathways underlying main focus on cells. In addition, this review demonstrates potential effects dysregulation disease.

Oxidative stress plays a pivotal role in developing and accelerating retinal diseases including age‐related macular degeneration (AMD), glaucoma, diabetic retinopathy (DR), vein occlusion (RVO). An excess amount of reactive oxygen species (ROS) can lead to functional morphological impairments pigment epithelium (RPE), endothelial cells, ganglion cells (RGCs). Here we demonstrate that edaravone, free radical scavenger, decreased apoptotic cell death, oxidative damage DNA lipids, angiogenesis through inhibiting JNK p38 MAPK pathways AMD, DR, RVO animal models. These data suggest the therapeutic strategy for targeting may be important treatment these ocular diseases, edaravone useful treating associated with stress.

Published: May 21, 2020

Mitochondria undergo dynamic fusion/fission, biogenesis and mitophagy in response to stimuli or stresses. Disruption of mitochondrial homeostasis could lead cell senescence, although the underlying mechanism remains unclear. We show that deletion phosphatase PGAM5 leads accelerated retinal pigment epithelial (RPE) senescence vitro vivo. Mechanistically, is required for fission through dephosphorylating DRP1. increased fusion decreased turnover. As results, cellular ATP reactive oxygen species (ROS) levels are elevated, mTOR IRF/IFN-β signaling pathways enhanced, leading senescence. Overexpression Drp1 K38A S637A mutant phenocopies rescues activation PGAM5-/- cells, respectively. Young but not aging Pgam5-/- mice resistant sodium iodate-induced RPE death. Our studies establish a link between defective fission, age-dependent oxidative stress response, which have implications age-related diseases.

Aging is a degenerative, biological, time-dependent, universally conserved process thus designed as one of the highest known risk factors for morbidity and mortality. Every individual has its own aging mechanisms both environmental conditions (75%) genetics (25%) account aging. Several theories have been proposed until now but not even single theory solves this mystery. There are still some queries un-answered to scientific community regarding behind However, oxidative stress (OST) considered famous that sees mitochondria leading organelles which largely contribute process.
