Phosphorylation of AktSer473/Ask1Ser83 in Trolox-induced suppression of doxorubicin-induced changes in rat cardiomyocytes
Bibliographic record
Abstract
To examine the modulatory effects of the antioxidant Trolox in the interplay of Akt and apoptosis signal-regulating kinase (Ask) 1 in doxorubicin (Dox)-induced oxidative stress (OS). METHODS: Rat cardiomyocytes were treated with Dox (5 M) or Trolox (20 M) for 24 h, or were pretreated with Trolox (20 M) for 4 h before treatment with Dox (5 M) for 24 h, and were compared with cardiomyocytes without any treatment. For the Akt inhibition study, cardiomyocytes were pretreated overnight with the phosphoinositol 3-kinase/Akt inhibitor wortmannin (1 M) before treatment with Dox, Trolox or Trolox + Dox. The gain and loss of Akt gene function with HA-tagged constitutively active Akt1 or dominant-negative mutant Akt1 (T308A; S473A) was also studied in the cardiomyocytes under all treatment conditions. Cells exposed to various treatment conditions were analyzed for OS, apoptotic and antiapoptotic proteins, and phosphorylation of Ask1 Ser83 , Ask1 Thr845 and Akt Ser473 .

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
