Differential expression of microRNA-2b with potential target coding P25 in the fifth instar larvae posterior silk gland of the silkworm
Bibliographic record
Abstract
MicroRNAs (miRNAs) are a class of non-protein coding small RNAs that regulate a gene expression at the post-transcriptional level. Using in silico screening, we found that the 3'-untranslated regions of the P25 gene mRNA are perfectly complementary to nucleotides 2-8 at the 5' end of the miRNA-2b (miR-2b). The expression of miR-2b and the P25 gene in posterior silk gland of the fifth instar larval silkworm was investigated using real-time PCR detection method. The results indicated that expression of the P25 gene was very high in the posterior silk gland during the fifth instar larvae, whereas a level of miR-2b sharply decreased until reaching the lowest one on the 8th day. The expression patterns of miR-2b and P25 gene indicate that miR-2b might act as a fine-tuning regulator of expression of the P25 gene at the post-transcriptional level.

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.
