Caspase 12 in Calnexin-Deficient Cells
Bibliographic record
Abstract
We investigated a role for calnexin, caspase 12, and Bap31 in endoplasmic reticulum stress-induced apoptosis in calnexin-deficient mouse embryonic fibroblasts and a calnexin-deficient human T cell line (NKR). We showed that calnexin-deficient mouse embryonic fibroblasts are relatively resistant to endoplasmic reticulum stress-induced apoptosis. Western blot analysis demonstrated that both wild-type and calnexin-deficient cells contained a caspase 12 protein. Caspase 12 expression was slightly inhibited in calnexin-deficient cells, and the protein carried out specific cleavage in the presence of thapsigargin. Immunoprecipitation experiments revealed that in the endoplasmic reticulum, caspase 12 forms complexes with Bap31 and calnexin. Treatment of wild-type cells with thapsigargin induced apoptosis and cleavage of Bap31. However, in the absence of calnexin, there was no significant cleavage of Bap31. There was also a negligible processing of caspase 8 in these cells. This work indicates that calnexin may play a role in modulating the sensitivity of a cell to apoptosis induced by endoplasmic reticulum stress, in conjunction with caspase 12 and Bap31.

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.
