Collagen Triple Helix Repeat Containing 1 Promotes Melanoma Cell Adhesion and Survival
Bibliographic record
Abstract
BACKGROUND: The extracellular protein collagen triple helix repeat containing 1 (CTHRC1) is aberrantly upregulated in melanoma and most human solid cancers. However, its role in cancer remains unknown. OBJECTIVE: In this study, we investigated the functional impact of CTHRC1 on melanoma cells in vitro. METHODS: Stable clones of cultured melanoma cells expressing different amounts of CTHRC1 protein were generated and evaluated to characterize their growth, survival, and attachment ability as well as their sensitivity to chemotherapy. RESULTS: In cultured MMAN and MMRU melanoma cells, increased expression of CTHRC1 protein resulted in morphologic cell changes, enhanced cell adhesion to culture surfaces, increased cell proliferation, and decreased apoptosis. Furthermore, decreased CTHRC1 expression through antisense inhibition enhanced temozolomide sensitivity. CONCLUSION: CTHRC1 expression influences cellular processes, including cell adhesion and survival. Additionally, CTHRC1 inhibition may represent a potential method for decreasing melanoma resistance to conventional chemotherapy.

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.
