An inherited deficiency of a metalloendopeptidase (meprin) activity occurs in kidneys of many inbred mouse strains. To clarify whether meprin protein is present in low-activity strains and determine the distribution of meprin in kidneys of mice with high- and low-meprin activities, kidney slices were stained through the use of the indirect immunoperoxidase technique and examined by light and electron microscopy. Light microscopy at high dilutions of anti-meprin IgG confirmed the brush border localization of meprin in high-meprin activity strains and revealed no detectable cross-reactive material in low-meprin activity strains. However, light and electron microscopy studies that use lower dilutions of anti-meprin immunoglobulin G (IgG) revealed cross-reactivity in low-activity strains, also at the luminal surface of the proximal tubules. Studies at lower magnifications indicated that meprin is primarily associated with the juxtamedullary region of the kidney in both high- and low-activity strains. Western blots of urinary proteins showed significant amounts of meprin-like proteins, but only in the urine of mice with high-meprin activity. The low activity of meprin in some inbred mouse strains is not associated with the presence of the protein in compartments of kidney cells other than the brush border or with secretion of the protein into the urine.

ABSTRACT Forty-four inbred and four randombred rat strains and 20 inbred mouse strains were examined for their Ah phenotype by determining the induction of liver microsomal aryl hydrocarbon (benzo[a]pyrene) hydroxylase activity (EC 1.14.14.1) by intraperitoneal treatment with either β-naphthoflavone or 3-methylcholanthrene. All 48 rat strains were found to be Ah-responsive. The maximally induced hydroxylase specific activities of the ALB/Pit, MNR/Pit, MR/Pit, SHR/Pit, and Sprague-Dawley strains were of the same order of magnitude as the basal hydroxylase specific activities of the ACI/Pit, F344/Pit, OKA/Pit, and MNR/N strains. Six of the 20 mouse strains were Ah-nonresponsive (i.e. lacking the normal induction response and presumably lacking detectable amounts of the Ah receptor). The basal hydroxylase specific activities of the BDL/N, NFS/N, STAR/N, and ST/JN mouse strains were more than twice as high as the maximally induced hydroxylase specific activity of the CBA/HT strain.——To date, 24 Ah-nonresponsive mouse strains have been identified, out of a total of 68 known to have been characterized. The reasons for not finding a single Ah-nonresponsive inbred rat strain—as compared with about one Ah-nonresponsive inbred mouse strain found for every three examined—remain unknown.
