Analysis of Human Thyroid Cancer-1 and Annexin V as Pro-Survival cDNA Sequences in Saccharomyces Cerevisiae
Bibliographic record
Abstract
Overexpressing a mouse Bax cDNA in yeast cells induces cell death. When heterologously expressed in yeast cells overexpression of a mouse cDNA encoding Bax, human Thyroid Cancer-1 (TC-1) or annexin V (ANXA5) suppresses the Bax induced cell death. My goal was to characterize the anti-Programmed Cell Death (anti-PCD) potential of these human cDNA sequences. In addition to rescuing Bax-expressing cells, I found that TC-1 and ANXA5 are pro-survival sequences that protect yeast from other death-inducing stresses including copper sulfate. TC-1 also prevented the deleterious effects caused by over-expression of a number of endogenous yeast pro-apoptotic sequences, including the YCA1 encoded metacaspase; the YBH3 encoded Bcl-2 Homology domain 3 protein, the NUC1 encoded DNase, as well as the apoptosis-inducing factor encoded by AIF1. Even though the protective effects were more pronounced in rescued cells over-expressing YBH3 and YCA1, TC-1 could still protect yeast mutant strains lacking YBH3 and YCA1 from the growth inhibitory effects of copper sulfate. Our results demonstrate that TC-1 and ANXA5 are pro-survival sequences that are able to attenuate stress-induced programmed cell death.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
