Gene expression profiling of the bovine gastrointestinal tract
Bibliographic record
Abstract
Basal gene expression levels across the bovine gastrointestinal tract (GI) were examined in an attempt to formulate genetic explanations for the differences in function that are known or thought to exist between the various regions. Gene expression along the tract was studied through the random sequencing of a total of 16 412 clones from seven tissue-specific cDNA libraries spanning its length. The expressed sequence tags (ESTs) within each library were clustered to reduce clone redundancy and obtain longer consensus sequences. BLASTN and BLASTX searches against the NCBI human RefSeq databases were used to find putative matches for the bovine sequences and gene ontology assignments were made. Notable similarities and differences in gene expression were observed among the various compartments of the GI tract of the bovine. Many of the prominent transcripts have yet to be reliably identified and the prominence of others may be worthy of further examination. This collection of ESTs represents an important resource for the future construction of a GI tract specific microarray for further gene expression studies.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
