In order to determine the effects of Zinc deficient diet on oxidative stress in testis and epididymis, various parameters viz: total proteins, lipid peroxidation, hydroperoxides, antioxidant capacity and enzymatic activities are evaluated in rats fed on zinc deficient diet for 2, 4 and 6 weeks. Total proteins, water and lipid solouble antioxidant capacity decreased while lipid peroxidation (TBA...

Macroorchidism (i.e., enlarged testicles) and mental retardation are the two hallmark symptoms of Fragile X syndrome (FraX). The disease is caused by loss of fragile X mental retardation protein (FMRP), an RNA-binding translational regulator. We previously established a FraX model in Drosophila, showing that the fly FMRP homologue, dFXR, acts as a negative translational regulator of microtubule...

The aim of this study was to examine the effects of cadmium (Cd), incorporated in radish bulbs, on malondialdehyde and glutathione levels and on superoxide dismutase activity in the liver, kidneys and testes of male rats. The control animals were given diet containing ordinary radish bulbs for 4, 8 and 12 weeks, while contaminated animals were given diet containing Cd-polluted radish bulbs (1.1...

AIM To determine the biochemical effect of di-(2-ethylhexyl) phthalate (DEHP) on testes, liver, kidneys and pancreas on day 10 in the process of degeneration of the seminiferous epithelium. METHODS Diets containing 2% DEHP were given to male Crlj:CD1(ICR) mice for 10 days. The dose of DEHP was 0.90 +/- 0.52 mg/mouse/day. Their testes, livers, kidneys and pancreata were examined for detection ...

INTRODUCTION Persistent Mullerian duct syndrome (PMDS) is a rare type of male pseudohermaphroditism. Transverse testicular ectopia (TTE) is characterized by one testis moving to the opposite side and both testes traversing the same inguinal canal. CASE PRESENTATION An 11-month-old boy presented with bilateral cryptorchidism. The left testis was not palpable; the right testis was canalicular w...

Bisphenol A (BPA) is a widely studied typical endocrine-disrupting chemical, and one of the major new issues is the safe replacement of this commonly used compound. Bisphenol S (BPS) and bisphenol F (BPF) are already or are planned to be used as BPA alternatives. With the use of a culture system that we developed (fetal testis assay [FeTA]), we previously showed that 10 nmol/L BPA reduces basal...

BACKGROUND In most mammals, the testes provide a stable environment for spermatogenesis, which depends on a lower temperature than the core body temperature. It has been reported that mild testicular heating safely and reversibly suppresses spermatogenesis, and is under consideration for its potential application as a male contraceptive. Previously, we focused on the molecular mechanism of germ...

The expression of LDH-C (Lactate dehydrogenase C) gene is restricted in mature germ cells; however multiple splice variants of LDH-C expressed in human cancers and yak normal testes were reported recently. In order to know if there are any LDH-C splice variants in human normal testes, we set out to clone the putative variants in human and rat. Four splicing variants in human testes, 1 splicing ...

Cnot7 is a co-factor of transcription regulation, expressed in a variety of tissues including the lung, liver, thyroid gland, and testis. Our previous study (Nakamura et al., 2004) showed that deletion of the Cnot7 gene in mice caused almost no abnormal phenotypes except for male infertility, due to oligo-astheno-teratozoospermia. This study also showed that Cnot7-/- mouse germ cells transplant...
