MiR-96 Downregulates REV1 and RAD51 to Promote Cellular Sensitivity to Cisplatin and PARP Inhibition
Bibliographic record
Abstract
Cell survival after DNA damage relies on DNA repair, the abrogation of which causes genomic instability. The DNA repair protein RAD51 and the trans-lesion synthesis DNA polymerase REV1 are required for resistance to DNA interstrand cross-linking agents such as cisplatin. In this study, we show that overexpression of miR-96 in human cancer cells reduces the levels of RAD51 and REV1 and impacts the cellular response to agents that cause DNA damage. MiR-96 directly targeted the coding region of RAD51 and the 3'-untranslated region of REV1. Overexpression of miR-96 decreased the efficiency of homologous recombination and enhanced sensitivity to the PARP inhibitor AZD2281 in vitro and to cisplatin both in vitro and in vivo. Taken together, our findings indicate that miR-96 regulates DNA repair and chemosensitivity by repressing RAD51 and REV1. As a therapeutic candidate, miR-96 may improve chemotherapeutic efficacy by increasing the sensitivity of cancer cells to DNA damage.

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.
