Mechanism of gender-divergent UDP-glucuronosyltransferase mRNA expression in mouse liver and kidney.
UDP-glucuronosyltransferases (UGTs) catalyze the addition of glucuronic acid to endo- and xenobiotics, increasing hydrophilicity and enhancing elimination. Gender-divergent glucuronidation rates are observed in humans and rats, and gender differences in UGT mRNA levels have been observed in rodents. The purpose of this study was to establish the hormonal regulation of gender-dependent Ugt mRNA ...
Animals generated by systematic mutagenesis and routine breeding are often infertile because they lack germ cells, and maintenance of such lines of animals has been impossible. We found a hermaphrodite infertile mouse in our colony, a genetic male with an abnormal Y chromosome lacking developing germ cells. We tried to clone this mouse by conventional nuclear transfer but without success. ES ce...
• Adult mouse displayed increased motor activity after postnatal corticosterone injections. A better rotorod acquisition was obtained in adult Postnatal injections facilitated visomotor control mouse. altered cerebellar morphology Glucocorticoids are involved the developing brain but, excessive amounts, may depress its growth and cause psychomotor development disorders. To test long-term vulner...
The DAZ (Deleted in AZoospermia) and DAZLA (DAZ-like autosomal) genes may be determinants of male infertility. The DAZ gene on the long arm of the human Y chromosome is a strong candidate for the 'azoospermia factor' (AZF). Its role in spermatogenesis is supported by its exclusive expression in testis, its deletion in a high percentage of males with azoospermia or severe oligospermia, and its h...
Previously we described a transgenic mouse model [FVB/NTg(CYP3A4-luc)Xen] using a reporter construct consisting of 13 kilobases of the human CYP3A4 promoter driving the firefly luciferase gene in the inbred FVB/N mouse strain. Here we report regulation of the same CYP3A4-luc reporter gene in a transgenic outbred mouse strain (CD-1) and in a transgenic rat (Sprague-Dawley). Basal reporter expres...
Purpose: The aim of this study was to investigate the effect of buserelin on apoptosis of male germ cells induced by busulfan in adult male mice. Materials and Methods: Male adult NMRI mice were divided into four group of eight each. Group 1 (control) administered PBS for 21 days subcutaneously, group 2 given 0.4 mg buserelin for 21 days subcutaneously, group 3 given single dose of 30 mg/kg bus...
LHRH-stimulated LH and FSH secretion was studied in hemipituitaries, in vitro, obtained from several dystrophic mouse mutants (male : 129/ReJ-dy ; 129B6F1/J\x=req-\ dy; C57BL/6J-dy and C57BL/6J-dy2J; female: 129B6F1/J-dy)and a dystrophic hamster mutant (male and female CHF-147). Without exception, pituitary tissue from dystrophic animals released significantly more FSH than did tissue obtained ...
Most human aneuploidies originate maternally, due in part to the presence of highly stringent checkpoints during male meiosis. Indeed, male sterility is common among aneuploid mice used to study chromosomal abnormalities, and male germline transmission of exogenous DNA has been rarely reported. Here we show that, despite aberrant testis architecture, males of the aneuploid Tc1 mouse strain prod...
Male germ cell development includes mitotic and meiotic cell divisions that are followed by dramatic morphological changes resulting in the production of spermatozoa. Genetic evidence has indicated that the DAZ family genes are critical for successful male germ cell development in diverse animals as well as humans. In the present study, we investigated the cellular functions of Dazl in the mous...
