Vascular presentation of cystathionine beta‐synthase deficiency in adulthood [PDF]

open access: yesJournal of Inherited Metabolic Disease, 2010
AbstractSeveral recent studies describing a solely vascular presentation of cystathionine beta‐synthase (CBS) deficiency in adulthood prompted us to analyze the frequency of patients manifesting with vascular complications in the Czech Republic. Between 1980 and 2009, a total of 20 Czech patients with CBS deficiency have been diagnosed yielding an ...

Low frequency dynamics of Cystathionine beta-synthase [PDF]

open access: yesBiophysical Journal, 2009
Femtosecond coherence spectroscopy is used to study the low frequency dynamics of cystathionine beta-synthase (CBS). CBS is a pyridoxal-5′-phosphate-dependent heme enzyme with cysteine and histidine axial ligands that catalyzes the condensation of serine and homocysteine to form cystathionine.

Cystathionine beta-synthase (CBS) contributes to advanced ovarian cancer progression and drug resistance. [PDF]

open access: yesPLoS ONE, 2013
Epithelial ovarian cancer is the leading cause of gynecologic cancer deaths. Most patients respond initially to platinum-based chemotherapy after surgical debulking, however relapse is very common and ultimately platinum resistance emerges. Understanding

One-carbon cycle alterations induced by Dyrk1a dosage

open access: yesMolecular Genetics and Metabolism Reports, 2014
Hyperhomocysteinemia due to cystathionine beta synthase deficiency confers diverse clinical manifestations. It is characterized by elevated plasma homocysteine levels, a common amino acid metabolized by remethylation to methionine or transsulfuration to ...

Ocular manifestations of homocystinuria due to cystathionine beta-synthase deficiency: A rare case report with genetic analysis

open access: yesTNOA Journal of Ophthalmic Science and Research, 2020
Microspherophakia is a developmental lens anomaly characterized by increased anteroposterior diameter and reduced equatorial diameter, which predisposes to secondary glaucoma. A 12-year-old boy presented with diminution of vision.

satmut_utils: a simulation and variant calling package for multiplexed assays of variant effect

open access: yesGenome Biology, 2023
The impact of millions of individual genetic variants on molecular phenotypes in coding sequences remains unknown. Multiplexed assays of variant effect (MAVEs) are scalable methods to annotate relevant variants, but existing software lacks ...

Sex-specific dysregulation of cysteine oxidation and the methionine and folate cycles in female cystathionine gamma-lyase null mice: a serendipitous model of the methylfolate trap

open access: yesBiology Open, 2015
In addition to its role in the endogenous synthesis of cysteine, cystathionine gamma-lyase (CGL) is a major physiological source of the vasorelaxant hydrogen sulfide.

Homocystinuria due to cystathionine beta synthase deficiency

open access: yesIndian Journal of Dermatology, Venereology and Leprology, 2008
A two year-old male child presented with cutis marmorata congenita universalis, brittle hair, mild mental retardation, and finger spasms. Biochemical findings include increased levels of homocysteine in the blood-106.62 micromol/L (normal levels: 5.90-16 micromol/L).

A continuous spectrophotometric assay for human cystathionine beta-synthase [PDF]

open access: yesAnalytical Biochemistry, 2005
We report a new continuous spectrophotometric assay for human cystathionine beta-synthase (hCBS). This assay relies upon the finding that hCBS will take cysteamine in place of L-homocysteine, thereby producing thialysine. Thialysine is, in turn, decarboxylated by lysine decarboxylase, releasing CO2 that is monitored by the sequential action of ...

Memantine Protects From Exacerbation of Ischemic Stroke and Blood Brain Barrier Disruption in Mild But Not Severe Hyperhomocysteinemia

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Hyperhomocysteinemia is a risk factor for ischemic stroke; however, a targeted treatment strategy is lacking partly because of limited understanding of the causal role of homocysteine in cerebrovascular pathogenesis.
