Exposure to hypobaric hypoxia causes oxidative damage to male rat reproductive function. The aim of this study was to evaluate the protective effect of a blueberry extract (BB-4) in testis of rats exposed to hypobaric hypoxia. Morphometric analysis, cellular DNA fragmentation, glutathione reductase (GR), and superoxide dismutase (SOD) activities were evaluated. Our results showed that supplemen...
Mammalian spermatogenesis occurs in a precise and coordinated manner in the seminiferous tubules. One of the attempts to understand the detailed biological process during mammalian spermatogenesis at the molecular level has been to identify the testis specific genes followed by study of the testicular expression pattern of the genes. From the subtracted cDNA library of rat testis prepared using...
Hedgehog (Hh) signalling has a crucial role in testis development. Sertoli cell-derived desert hedgehog (DHH) guides the formation of testis cords and differentiation of foetal-type Leydig cells. Dhh mutant mice are infertile due to a block in germ cell differentiation, hypogonadism and hypoandrogenism. Hh signalling pathway components are also expressed in postnatal testis. In the rat testis t...
We analyzed the gene and protein expression of serologically defined colon cancer antigen 8. Gene expression was upregulated in the maturing rat testis, and was localized to the spermatocytes. Protein was detected in the spermatids and at the sites of mRNA expression. Specific expression of colon cancer antigen 8 was observed in the maturing rat testis.
23 Iron is essential for male fertility and disruptions in iron balance lead to impairment of testicular 24 function. The divalent metal transporter DMT1 is a key modulator of transferrin and non-transferrin 25 bound iron homeostasis. As a first step in determining the role of DMT1 in the testis, we have 26 determined the pattern of DMT1 expression in the developing and adult rat testis. Northe...
Introduction: Methotrexate (MTX) is a chemotherapeutic agent that used for the treatment of a variety of tumors and inflammatory diseases. Methotrexate cause defective cogenesis, spermatogenesis, fertility impairment and different pathological changes on testis laboratory animals. The aim of this study was to investigate the effect of methotrexate administration on morphometerical changes...
Iron is essential for male fertility, and disruptions in iron balance lead to impairment of testicular function. The divalent metal transporter DMT1 is a key modulator of transferrin- and non-transferrin-bound iron homeostasis. As a first step in determining the role of DMT1 in the testis, we have characterized the pattern of DMT1 expression in the developing and adult rat testis. Northern blot...
BACKGROUND The high mobility group box chromosomal protein 1 (HMGB1) was originally shown to be a nuclear DNA-binding protein that activates transcription and promotes differentiation. More recently, there have been reports that HMGB1 may also function as a pro-inflammatory and antibacterial factor. The aim of this study was to investigate the testicular expression and antibacterial functions o...
