Expression of cholinesterases and their anchoring proteins in rat heart
Bibliographic record
Abstract
Acetylcholine (ACh)-mediated vagal transmission as well as nonneuronal ACh release are considered cardioprotective in pathological situations with increased sympathetic drive such as ischemia-reperfusion and cardiac remodeling. ACh action is terminated by hydrolysis by the cholinesterases (ChEs), acetylcholinesterase, and butyrylcholinesterase. Both ChEs exist in multiple molecular variants either soluble or anchored by specific anchoring proteins like collagen Q (ColQ) anchoring protein and proline-rich membrane anchoring protein (PRiMA). Here we assessed the expression of specific ChE molecular forms in different heart compartments using RT-qPCR. We show that both ChEs are expressed in all heart compartments but display different expression patterns. The acetylcholinesterase-T variant together with PRiMA and ColQ is predominantly expressed in rat atria. Butylcholinesterase is found in all heart compartments and is accompanied by both PRiMA and ColQ anchors. Its expression in the ventricular system suggests involvement in the nonneuronal cholinergic system. Additionally, two PRiMA variants are detected throughout the rat heart.

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.
