Cellular Aging, Senescence and Autophagy Processes in Osteoarthritis
Bibliographic record
Abstract
Osteoarthritis (OA) is the most common form of arthritis and a huge health and financial burden. The prevalence and incidence of OA are likely to rise due to increasing life expectancy. Although the link between aging and OA is well established, little is known about the mechanisms by which aging contributes to OA development. In recent years, progress has been made in understanding the molecular mechanisms of chondrocyte aging and senescence. Aging and senescent chondrocytes display a senescence-associated secretory phenotype (SASP) associated with increased secretion of pro-inflammatory mediators, extracellular matrix degrading enzymes and oxidative stress, all of which can contribute to the development and progression of OA. There is also evidence that autophagy, an essential homeostatic process, declines with aging and during OA. This review will focus on our current understanding of chondrocyte aging, senescence, and autophagy and their potential roles in the development and progression of OA. An understanding of these processes would be very useful in devising strategies to treat OA or to delay its development.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
