Abstract

fetched live from OpenAlex

2473 Trigonella foenum graecum (fenugreek) is traditionally used to treat disorders such as high cholesterol, diabetes, wounds, inflammation, and gastrointestinal ailments. Recently we have shown that diosgenin a major constituent of fenugreek inhibit human colon cancer cell growth and induce apoptosis and suppress the carcinogen-induced colonic aberrant crypt foci in rats (CEBP, 13: 1-7, 2004). However, there are no studies indicating disogenin indeed inhibits carcinoma formation in established animal models of colon cancer. The present double-blind study was designed to assess the potential chemopreventive properties of diosgenin on azoxymethane (AOM)-induced rat colon carcinogenesis. Colonic adenocarcinomas were chosen as chemopreventive efficacy end point. In addition, we assessed the markers of proliferation and apoptosis in colonic tumors and normal appearing crypt to understand the mechanism of tumor growth inhibition of diosgenin. Male F344 rats at 7-weeks of age were fed the control (AIN-76A diet) and one week later, rats received s.c. injections of AOM (15 mg/kg body wt., once weekly for 2 weeks) or equal volume of normal saline (vehicle). One week after the carcinogen treatment groups of rats fed experimental diets containing 0 or 0.1% of diosgenin and continued on the experimental diets for 48 weeks and sacrificed. Colon tumors were evaluated histopathologically and expression levels of markers associated with proliferation and apoptosis were determined in colon tumors and normal appearing colon. Administration of diosgenin significantly suppressed both invasive and non-invasive colon tumor incidence up to 60% (p

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.
