Abstract

fetched live from OpenAlex

Abstract Natural Killer (NK) lymphocytes are innate immune cells, mainly known to eliminate cancerous and virus infected cells. The NCR1/NKp46 receptor is expressed specifically in the NK lineage. Activation of NK effector functions results when the receptor binds viral haemagglutinin or unidentified tumor ligands. Knockout studies have shown that the molecule is indispensible in the control of influenza infection, lymphoma growth, and the development of type I diabetes. Yet the molecular basis behind the specificity of NCR1 expression is unknown. We seek to uncover the genetic and epigenetic mechanisms that regulate human NCR1 transcription. Comparative genomics and transient luciferase assays suggest that crucial cis-regulatory elements are found within 300bp upstream of the gene. Within this proximal region, luciferase experiments also indicate the presence of a basal, non-specific promoter as well as a tissue-specific regulatory switch. Through bioinformatics and transcription factor RNA expression screens, RUNX3 was identified as a probable regulator of the switch. Chromatin immunoprecipitation (ChIP) studies were conducted to confirm RUNX3 binding in NK cells. A proteomics approach is currently underway to identify additional factors. Finally, preliminary ChIP data hints at transcriptional control by histone 3 lysine 4 methylation in blood lineages.

Not 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.
