DNA methylation has been largely involved in the regulation of tissue-specific gene expression. The aim of the study was to determine the methylation pattern of steroid 5 alpha-reductase genes 1 and 2...
We have examined the structure of the major ribosomal RNA (rRNA) genes in the hamster sperm nucleus, using fluorescent in situ hybridization (FISH). The rRNA genes are present as tandemly repeated...
The gene for the sperm adhesion molecule 1 (PH-20), SPAM1, has been known to be testis-specific and exclusively haploid expressed. We show that in mice, the 2 common isoforms of the protein (Spam1...
Throughout spermatogenesis, germ cells move progressively from the basal to the adluminal compartment, which is accompanied by continual disassembly and reassembly of intercellular junctions sugge...
Leptin-deficient (ob/ob) male mice are morbidly obese and exhibit impaired reproductive function. The objective of this study was to assess the effect of a leptin deficiency on testicular morphology...
Globozoospermia, or round-headed sperm syndrome, is a unique form of male infertility characterized by sperm possessing a round head, lack of an acrosome, and a disorganized midpiece and tail. It ...
Previously, we examined the relationship between protamine gene variations and human male infertility. In this study, we show specific variability in the transition nuclear protein genes (TNPs) of...
The developing prostate gland is regulated by its hormonal milieu, most notably androgens, which dictate its growth and differentiation (Price, 1936; Lasnitzki and Mizuno, 1980). In addition, the ...
One role of the hedgehog (hh) signaling pathway during development is to assist in establishing pattern orientation in the embryo. The structure and function in the adult epididymis is highly patter...
Complementary DNA microarray and quantitative polymerase chain reaction were used as tools for discovering genes that are differentially expressed in the mouse under normal physiological condition...
Normal sperm production (spermatogenesis), maturation (spermiogenesis), delivery to and passage through the female genital tract (ejaculation and sperm transport), and function (capacitation, egg pene...
Using differential display reverse transcriptase–polymerase chain reaction (DDRT-PCR) we identified transcripts encoding for the RNA helicase mDEAH9, Ran binding protein 5 (RanBP5), and 3 novel comp...
