MicroRNA 138 upregulation is associated with decreasing levels of CCND1 gene expression and promoting cell death in human prostate cancer cell lines
Bibliographic record
Abstract
This research intended to discover the significance of miR-138 on the espression profile, proliferation, and the associated regulatory mechanisms in prostate cancer (PCa). RT-qPCR was applied to compare the expression of miR-138 in the PCa cells with a non-cancer cell line, as well as PCa tissue samples with benign prostatic hyperplasia (BPH) samples. The expression of miR-138 notably diminished in PCa tissues and cell lines. Afterward, formerly documented genes, along with bioinformatics analysis, suggested seven possible target genes of miR-138. Among them, CCND1 seemed to have higher expression in the PCa cell lines and tissues. Also, the negative correlation of miR-138 and CCND1 in PCa cell line and tissues was validated using Pearson correlation. CCDN1 was revealed to be the target gene of miR138 in the PC3 cell line based on the results of the luciferase reporter gene assay. Over-expression of miR138-5p suppressed the expression of CCDN1 in PCa cell lines as exhibited by RT-qPCR. Finally, the results of the MTT assay exhibited the inhibitory impact of miR-138 on the proliferative capacities in PCa cell lines. Our research introduces miR-138 as a negative regulator of CCDN1 in the progression of PCa with an inhibitory impact on the proliferation rate of prostate cancer (PCa) cell lines. This regulatory mechanism could be utilized for the design and target selection of remedial miRNA-based approaches.

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.
