Abstract
Glioblastoma is the most common primary brain tumor in adults and one of its hallmarks is resistance to apoptosis. Acyl-CoA: cholesterol acyltransferase (ACAT) is an intracellular membrane-bound enzyme that uses cholesterol and long chain fatty acyl-CoA as substrates to produce cholesteryl esters. The presence of cholesteryl esters in glioblastoma may be related to vascular and/or cell neoplastic proliferation in the tumor mass, two prerequisites for tumor cell growth. ACAT activity has been detected in glioblastoma cell homogenates. The present study is the first report on the effect of Avasimibe, a specific inhibitor of ACAT, on glioma cell lines (U87, A172 and GL261). Our results showed that Avasimibe inhibited ACAT-1 expression and cholesterol ester synthesis in glioma cell lines. Moreover, Avasimibe inhibited the growth of the cells by inducing cell cycle arrest and induced apoptosis as a result of caspase-8 and caspase-3 activation. Also, Our findings provide proof of principle that targeting ACAT-1 with the inhibitor Avasimibe could be an efficient therapy in the treatment of glioblastoma.

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 it
