Regulation of cystathionine gamma-lyase/H2S system and its pathological implication
Bibliographic record
Abstract
Hydrogen sulfide (H2S) is a highly diffusible gasotransmitter, that influence cellular and organ functions by a number of different mechanisms. Cystathionine gamma-lyase (CSE) is one major H2S-producing enzyme with L-cysteine as the main substrate in mammalian cells. Since the discovery of endogenously-produced H2S as a biological mediator, there has been an explosion of interest in CSE expression and regulation. CSE expression and activity and ultimately the amount of H2S synthesis is controlled by a complex integration of transcriptional, post-transcriptional and post-translational mechanisms. Considering the key role that CSE/H 2 S system plays in both health and diseases, a better understanding of the regulation of CSE/H 2 S system will help us to develop novel and more effective strategies to target CSE and alter H2S production inside cells. In this review, we summarize the altered expression and activity of CSE and abnormal H2S production in various pathophysiological conditions. The current knowledge on the signaling and regulatory pathways for CSE expression and H2S production are also elucidated. As such, our understanding of the pathogenesis of human diseases will be better achieved and the corresponding new therapy can be devised.

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.
