Cards

Term
mtALH2
Definition
metabolizes nitrates to NO and S-nitrothiols
Term
Guanlyl cyclase
Definition
converts GTP to cGMP, activated by NO and S-nitrothiols
Term
CYP3A4
Definition
metabolizes ranolazine, statins
Term
CKMB
Definition
two dimers, starts to rise after 2h of MI, peaks at 24h, normal by 72h
Term
Troponin
Definition
in skeletal and cardiac m, elevated at same time as CKMB, remains elevated 7-10d
Term
HMG CoA Reductase
Definition
rate-limiting step in cholesterol synthesis, inhibited by statins and monacolins
Term
SREBP
Definition
activated by statins, upregulates LDL-R to increase serum LDL uptake
Term
PPAR-a
Definition
activated by Fibric Acid
Term
Thrombin
Definition
coverts fibrinogen to fibrin
Term
Factor XIIIa
Definition
cross-links adjacent fibrin monomers
Term
Plasmin
Definition
serine protease, digest fibrin, A-chain is lysine binding site, B-chain has enzymatic activity, indiscriminate fibrin lysis leads to systemic lytic state
Term
Plasminogen
Definition
inactive zymogen of plasmin, synthesized in liver, converted by cleavage of Arg560, binds fibrin ad lysine-rich residues at N-terminus
Term
a2-antiplasmin
Definition
binds same site as fibrin, fibrin-bound plasmin is protected, forms a covalent complex with plasmin
Term
Plasminogen Activators
Definition
serine proteases, released from ECs, rapidly cleared from blood, inhibited by PAI-1/2, convert plasminogen to plasmin, very poor activator without fibrin
Term
PAI-1/2
Definition
inhibit ternary fibrin/plasminogen/tPA complex
Term
JAG1
Definition
deleted in Alagille Syndrome
Term
PTPN11
Definition
deleted in Noonan Syndrome
Term

Definition
deleted in Holt-Oram syndrome
Term
22q11
Definition
deleted in DiGeorge Syndrome
