Homozygous disruption of P450 side-chain cleavage (CYP11A1) is associated with prematurity, complete 46,XY sex reversal, and severe adrenal failure

, 2005
Disruption of the P450 side-chain cleavage cytochrome (P450scc) enzyme due to deleterious mutations of the CYP11A1 gene is thought to be incompatible with fetal survival because of impaired progesterone production by the fetoplacental unit.

Cefdinir reprograms Gram‐positive bacteria to synergize with lysozyme against superbugs

mLife, EarlyView.
Abstract Multidrug‐resistant (MDR) bacteria pose a critical global health threat, urgently requiring solutions. Cefdinir, the highest‐selling third‐generation cephalosporin but one now facing clinical obsolescence due to escalating resistance, is conventionally classified as a nascent cell wall synthesis inhibitor.

Branched‐Chain Amino and Keto Acids Reduce Hepatocyte Lipid Droplet Size and Number via Distinct Proteomic Pathways

PROTEOMICS, EarlyView.
ABSTRACT Branched‐chain amino acids (BCAA) and their corresponding keto acids (BCKA) have been associated with changes in hepatic lipid metabolism and the resulting alterations in intracellular triglyceride concentrations. In this study, we utilized a previously established hepatocyte model to investigate the impact of BCAA and BCKA supplementation on ...

Severe combined adrenal and gonadal deficiency caused by novel mutations in the cholesterol side chain cleavage enzyme, P450scc

, 2008
Context: Mitochondrial cytochrome P450scc converts cholesterol to pregnenolone in all steroidogenic tissues. Although progesterone production from the fetally-derived placenta is necessary to maintain pregnancy to term, four patients with mutations in ...

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

Environmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

Cytochrome P-450 mediated N-dealkylation.

, 2018
An investigation into the physico-chemical and molecular mechanical properties of tertiary amines which predispose them to rapid metabolism by cytochrome P-450 has been undertaken. A series of tertiary amines based on the common 2-(2,4-dichlorophenoxy)-N-
