Abstract

fetched live from OpenAlex

The expression of the DNA mismatch repair proteins hMSH2 and hMLH1 and p21(waf1) the cyclin G1 inhibitor, may determine response of adult cancers to anti-cancer drugs, that include alkylating agents and platinum-based drugs. The role of DNA mismatch repair proteins (hMSH2 and hMLH1) and p21(waf1) in pediatric tumor responses to chemotherapy and irradiation is described in the present study of 23 pediatric solid cancers (4 wilms' tumors, 9 neuroblastomas, 3 hepatoblastomas, 3 lymphomas and 4 sarcomas) using immunohistochemical methods. Immunostaining was scored for intensity (0-3) and extent (0-3). Most tumors stained strongly for hMSH2 and weakly or negative for hMLH1. All the hMLH1 negative tumors (1 wilms', 1 hepatoblastoma, 1 sarcoma, 2 lymphomas and 2 neuroblastomas) achieved complete response. p21(waf1) negative and positive tumors achieved relatively similar treatment response. The results suggest that the expression of DNA mismatch repair proteins hMLH1 and hMSH2, and p21(waf1) do not influence individual cancer responses to treatment and the results may reflect the use of multiple drugs and irradiation that cause many different types of DNA damage.

Teacher imitation

Not 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.
