In heterologous expression systems, KCNE2 has been demonstrated to interact with multiple α-subunits of voltage-dependent cation channels and modulate their functions. However, the physiological and pathological roles of KCNE2 in cardiomyocytes are poorly understood. The present study aimed to investigate the effects of bidirectional modulation of KCNE2 expression on action potential (AP) durat...

In light of previous observations that the range of arterial pressures over which cerebral blood flow is autoregulated differs dramatically in neonates and adults, the present experiments explored the hypothesis that pressure-induced intrinsic arterial tone is regulated differently in neonatal and adult cerebral arteries. In cannulated and pressurized endothelium-intact mouse cerebral arteries ...

objective: it is hypothesized that stem cells have the capability to form tumors after transplantation. spermatogonial stem cells have proliferation potency and colonization ability related to express pluripotency genes such as c-myc. the primary aim of this study is to investigate tumorigenicity ability of these cells after in vitro cultivation and inoculation in athymic animals. methods: sper...

Transmembrane 29 (Tmem29) gene with unknown function is a located on the X chromosome of mouse genome. The showed differential expression in Vannucci neonatal hypoxic-ischemic brain model. We found expresses different molecular forms, including group long non-coding RNA forming family transcripts. It was predominantly expressed testes, brain, and kidney mouse. In vitro identification functional...

Lysophosphatidic acid (LPA) known as a serum-derived growth factor, is involved in several cell physiological functions in the female reproductive system including: oocyte maturation, in vitro fertilization and embryo implantation by its transmembrane G protein-coupled receptors. The aim of the present study was to examine the effect of LPA on in vitro follicular development o...

PURPOSE Between days 8 and 14 of neonatal development, the corneal stroma of the mouse undergoes critical changes in tissue thickness, cell density, and light scattering. The authors investigate the stromal matrix structure in wild-type and lumican-deficient corneas in this developmental phase. METHODS Wild-type (n = 44) and lumican-deficient (n = 42) mouse corneas at neonatal days 8, 10, 12,...

Exposure of mice to a high dose of estrogens including diethylstilbestrol (DES) during the neonatal period modifies the developmental plan of the genital tract, which leads to various permanent changes in physiology, morphology and gene expression. These changes include development of an abnormal vaginal epithelium lined with hyperplastic mucinous cells accompanied by Tff1 gene expression in mi...

purpose: the purpose of this study is to model cryptosporidiosis in laboratory animals. the parasites were inoculated into animalsand thenmultiplied. the process of proliferation was compared to controlcryptosporidiosis in humans. materials and methods: twenty-five laboratory mice (4-7 days of age) and twenty-five laboratory rats (5 days of age) were assigned to the category i while the categor...

the aim of this sutdy is to prepare histocompatability y(hy) antibody in female mouse at the first phase (current study), and to separate mouse embryos with regard to their sex, to be able to obtain offsprings of disired sex, by means of hy antibody, at the second phase. totally 421 balb/c inbred mice were used. antibodies were produced in females by intraperitonial injections of spleen and tes...

Introduction Hematopoiesis in mouse fetal liver starts at 10 days of gestation and begins to decline after 15 days of gestation [1]. During postnatal hematopoietic involution, hepatocyte volume rapidly increases, and four types of specialized junctions; i.e., adherens junctions, desmosomes, tight junctions and gap junctions, appear to be fully developed in liver cells [2]. Neonatal livers exami...
