Aromatic hydrocarbon (AH) effects are mediated by binding of the AH receptor and its heterodimeric partner aromatic hydrocarbon nuclear translocator to specific response elements on DNA (AHREs). CYP1A2 expression is induced by AHs, yet AHREs have bee

Guinea pig CYP1A2 cDNA was isolated by RT-PCR from liver tissue of 3,3′-methylcholanthrene-treated guinea pigs. It shares considerable sequence identity with guinea pig CYP1A1 (nt 77%, aa 65%), but differs in levels of constitutive expression, func

Several immunochemical homologs of hepatic cytochromes P450 (CYPs) capable of steroid catabolism have been identified in the guinea pig adrenal cortex. Their predominance in males suggests a role in sex-differentiated metabolism of androgens. Therefo

Several cytochrome P450s have been identified in guinea pig adrenal microsomes which are distinct from the known steroidogenic P450s, c17 and c21, and are immunochemically related to cytochrome P450s found in liver. One, a 52 K protein related to P45

In the guinea pig adrenal the cells of the outer zone secrete high levels of steroid and respond to ACTH with increased synthesis of cholesterol and steroid. The outer zone consists of two cell types: zona fasciculata (ZF) and zona glomerulosa (ZG).

Steroid-secreting cells are characterized by abundant smooth endoplasmic reticulum whose membranes contain many enzymes involved in sterol and steroid synthesis. Yet they have relatively little morphologically identifiable rough endoplasmic reticulum

As have many institutions, the New York University School of Medicine (NYUSM) has instituted curriculum revisions that allow for increased independent study but impose significant time constraints on laboratory courses. Challenged by decreased labora

Steroid-secreting cells possess abundant smooth endoplasmic reticulum whose membranes contain many enzymes involved in sterol and steroid synthesis. In this study we demonstrate that adrenal smooth microsomal subfractions enriched in these membranes

Heterotopic adrenal tissue has been reported in multiple sites, but its functionality has seldom been assessed. In this case, immunocytochemistry was used to characterize adrenocortical tissue present in the subcapsular region of a nephrectomy specim

Guinea pig adrenal microsomes possess a distinctive cytochrome P450 that is immunochemically related to P4501 and correlates with microsomal capacity for xenobiotic metabolism. This 52K protein and the capacity for metabolizing compounds such as ethy
