WebClassic homocystinuria is due to mutations in the enzyme cystathionine beta synthase (CBS), leading to failure of conversion of homocysteine to cystathionine. Serum homocysteine is greatly increased in plasma (up to 100-fold) as is plasma methionine, and homocysteine is excreted in the urine. 1 The disorder is inherited in an autosomal ... WebMay 19, 2024 · Consistently, serum deoxycholic acid and lithocholic acid (FXR antagonists) were increased, and tauro-β-muricholic acid (FXR activation elevated) was reduced in CSE LKO. CSE/H 2 S promoted a post-translation modification (sulfhydration) of FXR at Cys138/141 sites, thereby enhancing its activity to modulate expression of target genes …
