AIMS: The present study is designed to consider a role for the circadian clock
protein Per1 in the regulation of the endothelin axis in mouse kidney, lung,
liver and heart. Renal endothelin-1 (ET-1) is a regulator of the epithelial
sodium channel (ENaC) and blood pressure (BP), via activation of both endothelin
receptors, ETA and ETB. However, ET-1 mediates many complex events in other
tissues. MAIN METHODS: Tissues were collected in the middle of murine rest and
active phases, at noon and midnight, respectively. ET-1, ETA and ETB mRNA
expressions were measured in the lung, heart, liver, renal inner medulla and
renal cortex of wild type and Per1 heterozygous mice using real-time quantitative
RT-PCR. KEY FINDINGS: The effect of reduced Per1 expression on levels of mRNAs
and the time-dependent regulation of expression of the endothelin axis genes
appeared to be tissue-specific. In the renal inner medulla and the liver, ETA and
ETB exhibited peaks of expression in opposite circadian phases. In contrast,
expressions of ET-1, ETA and ETB in the lung did not appear to vary with time,
but ET-1 expression was dramatically decreased in this tissue in Per1
heterozygous mice. Interestingly, ET-1 and ETA, but not ETB, were expressed in a
time-dependent manner in the heart. SIGNIFICANCE: Per1 appears to regulate
expression of the endothelin axis genes in a tissue-specific and time-dependent
manner. These observations have important implications for our understanding of
the best time of day to deliver endothelin receptor antagonists.
