Human Medullary Thyroid Carcinoma: A Source and Potential Target for Relaxin‐Like Hormones
Bibliographic record
Abstract
We investigated the expression of H1, H2 relaxin and INSL-3, mRNA and protein, and LGR7 and LGR8 transcripts in human C-cell hyperplasia, primary medullary thyroid carcinoma (MTC) tissues, MTC metastases, and the human MTC-TT and mouse MTC-M cell lines. Relaxin-like peptide hormones were detected in C-cell hyperplasia and in MTC tissues, but were absent in human normal parafollicular C-cells of benign goiter tissues. In contrast to calcitonin, mRNA, and immunoreactive protein, no differences in the expression of relaxin and INSL3 were observed in MTC tissues of different pTNM classification or between primary and metastatic MTC tissues studied. All MTC tissues constitutively expressed LGR7 and LGR8 transcripts. Thus, relaxin-like hormones appear to be present early during C-cell hyperplasia and potentially functional relaxin/INSL3 ligand-receptor systems are present in human MTC tissues and in MTC cell lines.

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.
