HERG K+ channel, a regulator of tumor cell apoptosis and proliferation.
Bibliographic record
Abstract
The human ether-a-go-go related gene (HERG) encodes K+ channel identified as a molecular target for mutations underlying some forms of the long Q-T syndrome, a lethal cardiac arrhythmia. Recent studies revealed that HERG is abundantly expressed in a variety of tumor cells. Yet, the role of HERG in tumor cells had remained unclear. Here, we show that HERG conductance markedly promotes H2O2-induced apoptosis of various tumor cells, whereas HERG expression facilitates the tumor cell proliferation caused by tumor necrosis factor (TNF) ligand (TNF-alpha). Immunostaining and immunocoprecipitation reveal coexpression of HERG and TNF receptor 1 on the cytoplasmic membrane, which is correlated with greater activities of nuclear transcription factor, nuclear factor-kappaB, in HERG-expressing tumor cells. Our data suggest that HERG K+ channel is a regulator of tumor cell proliferation and apoptosis and provide a potential new target for cancer therapy.

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.
