Project description:To investigate the function of Desertliving Cistanche herb in the postmenopausal osteoporosis, we established ovariectomized rats in which both ovaried were removed.We performed gene expression profiling alalysisi using date obtained from RNA-seq of ovariectomized rats of postmenopausal osteoporosis.

Project description:To assess the changes in circulating microRNA (miRNA) expression profiles associated with the potential osteoprotective effect of diosgenin (DIO) in ovariectomized (OVX) rats.
Project description:Appropriate nutrition during early development is essential for optimal bone mass accretion; however, linkage between early nutrition, childhood bone mass and prevention of bone loss later in life has not been extensively studied. In this report, we have demonstrated several fundamental issues in the field. 1) A significant prevention of ovariectomy (OVX) -induced bone loss from adult rats can occur with only 14 days consumption of a blueberry-containing diet immediately prior to puberty. 2) The molecular mechanisms underlying these effects involve increased myosin production and preserved a shuttle for transcription factors such as Runx2 from cytoplasm to nucleolus which stimulates osteoblast differentiation and reduces mesenchymal stromal cell senescence. 3) The effects of blueberry diet on preserving fidelity of osteoblast differentiation also overcome reduced osteoblast differentiation and activity due to OVX-induced degradation of collagen matrix. Bone quality was compared among casein control diet sham operated, casein diet ovariectomized, long term BB diet ovariectomized, and short term BB diet ovariectomized female rats
Project description:Epilepsy in women is often accompanied by hormonal disturbances including irregular cycles and premature onset of menopause. Decline in estrogen levels results in increased risk for neurodegenerative diseases, with strong participation of chronic inflammation. We have shown that estradiol (EB) has neuroprotective effects against seizure-induced damage in the sensitive hilar region of hippocampal dentate gyrus associated with neuropeptide Y (NPY) upregulation. Here, we quantify the alterations caused by kainic acid-induced status epilepticus in the glutamatergic, GABAergic, dopaminergic, cholinergic and serotonergic synapse transcriptomes of dentate gyrus of ovariectomized female rats and the recovery effects of the EB replacement. Our data indicate that the EB replacement reduces the number of significantly regulated genes in seizured ovariectomized female rats by about 45%. The new measure Pathway Restoration Efficiency (PRE) indicates the dopaminergic synapse to be the most protected (65%) and the GABAergic synapse the least protected (37%) by the EB replacement.
Project description:This study is designed to compare and contrast the temporal and spatial changes in bone formation rates and transcriptional profiles in cortical and cancellous bone cell populations enriched by laser capture microdissection (LCM) in ovariectomized rats administered Scl-Ab by subcutaneous injection for up to 26 consecutive weeks, followed by a recovery period of up to 18 weeks.

Project description:Uterine tissue is highly responsive to estrogen, which plays a mayor role in sympathetic innervation remodeling in myometrium; Microarrays were used to investigate which estrogen resposive myometrial proteins can be involved in innervation modulation Experiment Overall Design: Mature female rats were ovariectomized, than treated with estradiol benzoate or vechicle, myometrial samples were analyzed 6 or 24 h after treatment
