Prevention of Renal Ischemic Injury by Silencing the Expression of Renal Caspase 3 and Caspase 8
Bibliographic record
Abstract
BACKGROUND: Apoptotic pathways mediated by caspases play a critical role in renal ischemia-reperfusion injury (IRI). Downregulation of the caspase cascade, using small interfering RNA (siRNA) to silence the expression of caspase 3 and caspase 8, may have substantial therapeutic potential for limiting renal injury. METHODS: IRI was induced in mice by clamping of the renal vein and artery for 25 or 35 min at 37 degrees C. Caspase 3 and caspase 8 (caspase 3/8) siRNA was administrated by hydrodynamic injection. Quantitative polymerase chain reaction (PCR) and immunohistochemistry were used to analyze the gene silencing efficacy, and the therapeutic effects of siRNA were evaluated by renal function analysis, histological examination, and overall survival of mice suffering from IRI. RESULTS: In this study, we have shown, using quantitative PCR, that IRI is associated with increased levels of renal caspase 3/8 mRNA. Mice treated with caspase 3/8 siRNA showed a significant down-regulation in kidney expression of caspase 3/8 at both, transcriptional and protein levels. Kidney function in IRI was protected by siRNA therapy, as levels of blood urea nitrogen and creatinine were significantly reduced in mice treated with siRNA. Histological examination demonstrated that tissue injury caused by IRI was significantly reduced as a result of caspase 3/8 siRNA treatment. Furthermore, survival data showed that more than 70% of mice in siRNA-treated groups survived until the end of the eight-day observation period. CONCLUSION: Herein, we have demonstrated the therapeutic potential of using siRNA to knock down the expression of caspases and prevent acute renal injury.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
