L-Ascorbic acid affect the DNA methytransferase expression in Mouse Embryonic Fibroblasts
Bibliographic record
Abstract
Introduction: Induced pluripotent stem cells (iPSCs) can be generated from different source of cells with different efficiencies. Two DNA methyltransferases DNMT1 and DNMT3A have been shown to regulate epigenetically the gene expression involved in cell viability and reprogramming. L-ascorbic acid (L-AA) is a chemical factor that can accelerate reprogramming. Here, we sought to investigate the effect of L-AA on DNMT1 and DNMT3A expressions. Materials and Methods: First, mouse embryonic fibroblasts at passage 3 were cultured in the presence of 10 µg/ml L-AA days for 5 days. Then, DNMT1 and DNMT3A expressions were determined using real-time PCR at days 3 and 5. Results: It was showed that L-AA could enhance DNMT-1 expression which involve in cell viability and decrease the DNMT3A which involve in cell differentiation. Conclusion: The results therefore suggest a new insight into L-AA mechanism impact on reprogramming process.

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.
