Intravital microscopy analysis of the mesenteric venules showed that leukocyte rolling velocity was markedly decreased and numbers of adherent cells were increased in the mutant mice.
WebDeficiency of cystathionine beta-synthase (CBS) is a genetic disorder of transsulfuration resulting in elevated plasma homocyst(e)ine and methionine and decreased cysteine. Affected patients have multisystem involvement, which may include light skin and hair. ... Copper sulfate restored homocyst(e)ine-inhibited tyrosinase activity when added to ... WebMar 6, 2012 · In most cases, homocystinuria is caused by reduced activity of an enzyme known as cystathionine beta-synthase and this results in CBS deficiency. Infants who develop homocystinuria due to CBS deficiency (which is also known as classical homocystinuria) may fail to grow, or grow longer too fast, often have difficulty with gain …
WebOur previous study demonstrated that cystathionine β synthase (CBS) is highly expressed in the cumulus–oocyte complex during ovulation. However, the role of CBS during oocyte maturation remains uncertain. In this study, a small-interfering (si) RNA interference (siRNA) approach was used to investigate the potential role of CBS during oocyte maturation.
