A role for Wnt-4 in adrenal gland development and function is pointed to, and some cells that are positive for Cyp21, which is normally expressed only in the adrenal glands, are found in the gonads of WNT-4-deficient embryos, indicating that Wnt -4 may play a role in cell migration or in the sorting of adrenal and gonadal cells during early development.
Mechanisms of atrial and brain natriuretic peptide release from rat ventricular myocardium: effect of stretching.

It is indicated that stretch stimulates both ANP and BNP secretion from hypertropic ventricular myocytes, and the results suggest that protein kinase-C may be involved in stretch-induced ventricular ANP release, whereas the influx of extracellular calcium may not be necessary.

It is concluded that apela is present in the adult heart, is upregulated in post-infarction cardiac remodeling, and increases cardiac contractility in an ERK1/2-dependent manner.
Molecular heterogeneity has a major impact on the measurement of circulating N-terminal fragments of A- and B-type natriuretic peptides.

Molecular heterogeneity of the circulating forms causes a serious risk of preanalytical errors in assays for NT-proBNP and, to a lesser extent,NT-proANP.
Hypoxia inducible factor regulates the cardiac expression and secretion of apelin

It is shown that hypoxia increases the apelin expression in rat myocardium and in cultured cardiomyocytes, suggesting a role for apelin as a potential marker for acute cardiac Hypoxia with a possible compensatory role in myocardial tissue suffering from oxygen deprivation.
Involvement of transcriptional and posttranscriptional mechanisms in cardiac overload-induced increase of B-type natriuretic peptide gene expression.

It is demonstrated that the early increase of BNP mRNA levels by mechanical stretch results from increased transcriptional activation and is independent of protein synthesis, suggesting that protein kinase C and tyrosine kinases activities may be involved in coupling cardiac overload to alterations in atrial BNP synthesis.
Brain natriuretic peptide in plasma, atria, and ventricles of vasopressin- and phenylephrine-infused conscious rats.

The present study shows that pressure overload rapidly stimulates BNP gene expression in the hearts of normal and hypertensive rats, and locally generated BNP in the heart muscle may play a significant role in cardiac adaptation to acute changes in mechanical load.

Ghrelin induces vasoconstriction in the rat coronary vasculature without altering cardiac peptide secretion.

The first evidence that ghrelin has a coronary vasoconstrictor action that is dependent on Ca(2+) and PKC is provided and the observation that immunoreactive gh Relin is found in cardiac tissue suggests the presence of a local cardiacghrelin system.
