Mammalian reproductive strategies: genes, photoperiod and latitude.
This paper considers how and why natural selection might promote or block the photoperiodic regulation of a mammal's reproduction. The factors most important in making this decision would seem to be the following: life expectancy, length of the female's cycle, feeding strategy, the presence or absence of survival mechanisms like hibernation, and the nature of the seasonal challenges offered by ...
متن کاملPhytoestrogen Biological Actions on Mammalian Reproductive System and Cancer Growth
Phytoestrogens are a family of diverse polyphenolic compounds derived from nature plant that structurally or functionally mimic circulating estrogen in the mammalian reproductive system. They induce estrogenic and anti-estrogenic effects in the brain-pituitary-gonad axis (a principal endocrine system involving in reproductive regulation) and peripheral reproductive organs. The dichotomy of phyt...
متن کاملP-65: Maternal Effect Genes in Mammalian Reproduction
Background: Regulation of gene expression in mammalian embryos is not completely known. Pre-implantation embryos need maternal RNA and proteins synthesized during oogenesis, to regulate development before mater-embryo transition, as the grown oocyte and the 1-cell zygote are transcriptionally silent. There are some oocyte-specific genes called maternal effect genes which may account for this ea...
متن کاملMammalian reproductive tract mucins.
Mucin glycoproteins are major constituents of the glycocalyx that covers mucosal epithelium. Two broad classes of mucins exist: membrane-associated and secretory. Of the secreted mucins, those with cysteine-rich regions are thought to polymerize through disulphide bonds. Among these gel-forming mucins are MUC2, MUC5AC, MUC5B and possibly MUC6. MUC7 lacks cysteine-rich domains and is thought to ...
متن کاملMammalian Olfaction, Reproductive
Although for many animals olfactive perceptions must be the most important source of information about the state of their environment, we know relatively little about this chemoreceptive sensory system. The fact that our own sense of smell is comparatively rudimentary has certainly contributed to the relative lack of attention that olfactory behaviour and physiology have received. Our smelling ...
