Abstract

fetched live from OpenAlex

Necroptosis triggers an inflammatory cascade associated with antimicrobial defense. No prospective human study has yet explored the role of necroptosis in colorectal cancer development. We conducted quantitative analysis of biomarkers for necroptosis [transient receptor potential cation channel subfamily M member 7 (TRPM7) and phosphorylated mixed lineage kinase domain-like protein], inflammation [cyclooxygenase-2 (COX-2)], apoptosis [BCL2-associated X (BAX) and terminal deoxynucleotidyl transferase dUTP nick end labeling], and cell proliferation (Ki67). This was done using tissue microarray biospecimens from the Cooperative Human Tissue Network and rectal biopsies from a longitudinal study within the Personalized Prevention of Colorectal Cancer Trial. In the human colorectal adenoma-carcinoma sequence, we observed an inverse expression trend between BAX and TRPM7; TRPM7 decreased from normal mucosa to small and large adenomas but significantly increased in early colorectal cancer stages (Ptrend = 0.004). It maintained high levels through all cancer stages. An increased COX-2 intensity in the epithelium was noted during tumorigenesis (Ptrend = 0.02) and was significantly associated with an elevated risk of metachronous polyps (odds ratio = 3.04; 95% confidence interval, 1.07-8.61; Ptrend = 0.02). The combined composite index scores of TRPM7 and COX-2 were strongly linked to 6- to 47-fold increased risks for metachronous adenoma/serrated polyps, whereas combined scores of phosphorylated mixed lineage kinase domain-like protein or TRPM7 with BAX were associated with an 11.5- or 13.3-fold elevated risk for metachronous serrated polyps. In conclusion, our findings suggest that COX-2 expression within normal-looking colorectal mucosa is significantly associated with an increased risk of metachronous colorectal polyp. Furthermore, our results propose the hypothesis that synergistic interactions among necroptosis, inflammation, and apoptosis could play a pivotal role in human colorectal tumorigenesis. Prevention Relevance: Our findings suggest that COX-2 expression and combined scores of COX-2, TRPM7, and BAX hold promise for predicting the risk of metachronous polyps and could potentially serve as a tool for assessing the effectiveness of chemopreventive agents in preventing colorectal cancer during intervention trials.

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.
