Huperzine A, a novel cholinesterase inhibitor, was found to inhibit the N-methyl-D-aspartate (NMDA) receptors in the brain. In this study, the mechanisms of the NMDA receptor inhibition were investigated using [3H]dizocilpine (MK-801) binding in synaptic membrane of rat cerebral cortex. Changing the concentrations of L-glutamate and L-glycine did not alter(More)
Superior kidding rate is an important economic trait in production of meat goat, and ovulation rate is the precondition of kidding rate. MicroRNAs (miRNAs) play critical roles in almost all ovarian biological processes, including folliculogenesis, follicle development, follicle atresia, luteal development and regression. To find out the different ovarian(More)
Ovarian follicular development and hormone secretion are complex and coordinated biological processes which will usually be altered during pregnancy. Ovarian function is tightly regulated by a multitude of genes, and also by some specific miRNAs. It is necessary to identify the differentially expressed miRNAs in the ovaries of pregnant and non-pregnant(More)
Pluripotent stem cells from domesticated animals have potential applications in transgenic breeding. Here, we describe induced pluripotent stem (iPS) cells derived from bovine fetal fibroblasts by lentiviral transduction of Oct4, Sox2, Klf4 and c-Myc defined-factor fusion proteins. Bovine iPS cells showed typical colony morphology, normal karyotypes,(More)
Induced pluripotent stem cells (iPSCs) are somatic cells reprogrammed by ectopic expression of transcription factors or small molecule treatment, which resemble embryonic stem cells (ESCs). They hold great promise for improving the generation of genetically modified large animals. However, few porcine iPSCs (piPSCs) lines obtained currently can support(More)
We have developed a new multichannel spectral imaging laser scanning confocal microscope for effective detection of multiple fluorescent labeling in the research of biological tissues. In this paper, the design and key technologies of the system are introduced. Representative results on confocal imaging, 3-dimensional sectioning imaging, and spectral(More)
BACKGROUND Many groups of Gram-negative bacteria cause diseases harmful to sheep. TLR4 is an important Toll-like receptor (TLR) which responds to common Gram-negative bacterial infections. Activation of TLR4 leads to the induction of inflammatory responses, which is a linkage between the innate and adaptive immune systems. A vector pTLR4-3S was constructed(More)
Adipose-derived stem cells (ADSCs), a subset of mesenchymal stem cells, have promising potential for regenerative medicine applications. However, the efficient culture of mouse adipose-derived stem cells (mADSCs) is complicated or impracticable and many properties of mADSCs are still unknown. Here, we report that vitamin C (Vc) is available for the(More)
A vector expressing human lysozyme (pBC1-hLYZ-GFP-Neo) was evaluated for gene and protein expression following liposome-mediated transformation of C-127 mouse mammary cancer cells. Cultures of G418-resistant clones were harvested 24–72 h after induction with prolactin, insulin and hydrocortisone. Target gene expression was analyzed by RT-PCR and Western(More)
