Introduction: Nowadays, there is special interest in finding a new contraceptive drug with high safety and fewer side effects. Investigations have shown that dill (Anethum graveolens L.) can be used either as a menstrual cycle regulator or contraceptive. Since cell surface terminal sugars have crucial roles in oocyte maturation, fertilization and implantation, in this study we investigated the ...
The expression patterns of folate receptor (FR) isoforms, alpha and beta, in normal and malignant male and female reproductive tissues is described. The significance of the receptor in reproductive and developmental physiology is discussed. The potential value of the receptor expressed in malignant tissues including ovarian and endometrial cancers as a diagnostic marker and a therapeutic target...
Circadian rhythms in physiology and behavior are known to be influenced by the estrous cycle in female rodents. The clock genes responsible for the generation of circadian oscillations are widely expressed both within the central nervous system and peripheral tissues, including those that comprise the reproductive system. To address whether the estrous cycle affects rhythms of clock gene expres...
Aging is an important feature of animal biology characterized by progressive, degenerative changes in somatic and reproductive tissues. The rate of age-related degeneration is genetically controlled, since genes that influence lifespan have been identified. However, little is known about genes that affect reproductive aging or aging of specific somatic tissues. To identify genes that are import...
The posttranscriptional gene regulation mediated by microRNA plays an important role in the development and function of male and female reproductive organs and germ cells in mammals, including cattle. In the present study, we identified novel and differentially expressed miRNAs in the testis and ovary in Holstein cattle by combining the Solexa sequencing with bioinformatics. In total 100 and 10...
BACKGROUND Estrogen is known to have important effects on both reproductive and non-reproductive tissues. Moreover, there is increasing interest in developing compounds that may have selective effects on bone versus reproductive tissues. METHODS Since mouse models are often used in these studies, we administrated increasing doses of estradiol (E2) (0 to 500 microg/kg/day) by slow release pell...
