DDAH1

Some search terms matched

DDAH1 encodes an enzyme that breaks down asymmetric dimethylarginine, or ADMA. ADMA inhibits nitric oxide synthase; DDAH1 is part of its clearance system, not the inhibitor itself. Also called: Clearing ADMA helps preserve nitric oxide sig…

F5

Some search terms matched

F5 encodes coagulation factor V. The well-characterized Factor V Leiden variant, rs6025, can make factor V less responsive to an anticoagulant control mechanism, increasing susceptibility to venous clots. It does not mean the body cannot ma…

HMGB1

Some search terms matched

HMGB1 normally has functions inside the cell nucleus. When released outside cells in particular settings, it can act as a damage-associated molecular pattern, or DAMP, participating in inflammatory signaling. Also called: A cellular protei…

Best match puts all-term matches before partial matches and related reading. Identical social posts and matching long titles across other sources are grouped when access is the same. Search covers published titles, descriptions, available article text, report overviews, and the full text of the nutrient, gene and learning-essential reference pages. Books, uploaded chapters and downloads-page reports are searchable through selected editorial guides and topic names; the original files and full book text are not published. Full Drive reports are not copied into search. Substack subscriber titles and public summaries are included; full subscriber content opens on Substack. Video transcripts are added when available.
