Abstract

fetched live from OpenAlex

We sequenced the promoter and coding regions of PCK1 encoding cytosolic phosphoenolpyruvate carboxykinase from genomic DNA of subjects with type 2 diabetes mellitus (DM). We found nine single nucleotide polymorphisms (SNPs) that were present with varying allele frequencies and pairwise linkage disequilibrium relationships in different ethnic groups. The -232C-->G promoter SNP was within a cis-acting element required for basal and cAMP-mediated PCK1 gene transcription. The expression of a luciferase reporter construct containing -232G in three different cell lines showed significantly increased basal expression with no down-regulation by insulin compared with a construct containing -232C. The odds ratios for type 2 DM among subjects with one or two copies of -232G compared with -232C/C homozygotes were 1.9 (95% confidence interval, 1.2-3.0) in a Canadian aboriginal sample and 2.8 (95% confidence interval, 1.7-4.7) in a Caucasian sample. Thus, we report a promoter SNP in PCK1 that was resistant to down-regulation by insulin in vitro and was associated with type 2 DM in two independent study samples.

Teacher imitation

Not 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.
