Background Poly cystic ovarian syndrome (PCOS) is known as a common endocrine disorder in women at reproductive ages and may cause developmental abnormality in oocyte. ERK has found as a regulator protein of Gap junctions (GJ) function and the level of exchanges between two neighbors cells, for example oocyte and surrounding cumulus cells (CCs) in the mammalian ovary. Such exchange is essential...

The aldehyde reagent methoxyamine is able to interact with apurinic/apyrimidinic sites formed in vivo within cells and displays both an anti-cytotoxic and an antimutagenic activity on N-ethyl-N'-nitro-N-nitrosoguanidine-induced DNA damage in Chinese hamster ovary cells. To clarify the underlying mechanism we have examined the mutational spectra induced by N-ethyl-N'-nitro-N-nitrosoguanidine alo...

To clarify the underlying mechanism we have examined the mutational spec tra induced by A'-ethyl-W-nitro-A'-nitrosoguanidin...

Objective: The possible toxicity of drugs in pregnancy should be tested before their use in pregnant patients. In the present study, we aimed to evaluate the safety of phytovagex, a pessary formulation of Nigella sativa (N. sativa), which is already in clinical use for vaginal fungal infection. Materials and Methods: The pregnant rats were treated intravaginal with physiological saline (vehicle...

Mammalian ovary development undergoes important changes during the perinatal period, moment when follicles are assembled and start to develop in a process not well known, involving endocrine and paracrine factors. In order to investigate the effect of two different hormonal environments on the early development of the ovary, we used an autologous transplant model in which Syrian hamster fetal o...

To explore the function of kaempferol on lung cancer cell A549 and microRNA-199 variation is objective study. The proliferation was detected by counting kit-8. expression mammalian target rapamycin, phosphorylated light chain 3-?/?, beclin-1, B-cell lymphoma 2 2-associated X protein showed Western blot. determined quantitative polymerase reaction. adenocarcinomic human alveolar basal epithelial...

The origin decision point (ODP) was originally identified as a distinct point during G1-phase when Chinese hamster ovary (CHO) cell nuclei experience a transition that is required for specific recognition of the dihydrofolate reductase (DHFR) origin locus by Xenopus egg extracts. Passage of cells through the ODP requires a mitogen-independent protein kinase that is activated prior to restrictio...
