What's a GeneRIF?

The effect of dietary plant extracts and vegetable oils on hepatic SREBP-1c, Delta5 and Delta6 desaturases has been reported.
Title: Adding a purple corn extract in rats supplemented with chia oil decreases gene expression of SREBP-1c and retains Δ5 and Δ6 hepatic desaturase activity, unmodified the hepatic lipid profile.
testicular distribution of Delta5- and Delta6-desaturase and stearoyl-CoA desaturase 1 and 2 shows that all four desaturases seem to be localized in the Sertoli cells, with far lower expression in germ cells
Title: Expression and regulation of delta5-desaturase, delta6-desaturase, stearoyl-coenzyme A (CoA) desaturase 1, and stearoyl-CoA desaturase 2 in rat testis.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
