ABSTRACT
Relationship between family-3A cytochrome P-450-dependent (troleandomycin inhibitable) and maternal environmental-dependent systolic blood pressure (SBP) was investigated in spontaneously hypertensive rats (SHR). Adult SHR nursed by foster or natural SHR mothers had indistinguishable SBP. Troleandomycin reduced 50% of Wistar-Kyoto (WKY)-SHR strain difference in SBP. SHR having WKY foster mothers had SBP similar to troleandomycin-reduced SHR levels, which was unaffected by troleandomycin. The two components of SBP elevation appear identical. Because observations of others demonstrated that WKY fostered to SHR show no SBP increase, the maternally dependent/troleandomycin-sensitive component of SBP elevation may reflect epistatic interaction between genes determining maternal differences and offspring sensitivity, respectively.
