G-protein coupled receptors may have a role in mediating the antiepileptogenic effect of low-frequency stimulation (LFS) on kindling acquisition. This effect is accompanied by changes at the intracellular level of cAMP. In the present study, the effect of rolipram as a phosphodiesterase inhibitor on the antiepileptogenic effect of LFS was investigated. Meanwhile, the expression of αs- and αi-subunit of G proteins and regulators of G-protein signaling (RGS) proteins following LFS application was measured. Male Wistar rats were kindled by perforant path stimulation in a semi-rapid kindling manner (12 stimulations per day) during a period of 6days...

BACKGROUND: Catamenial epilepsy is a common central nervous system disease in female, which is influenced by the 17-β-estradiol (estrogen) level during the menstrual cycle. Low level (<0.05ng/ml) of estrogen normally accompanies with the perimenstrual classification of catamenial epilepsy, however, without clear mechanism. In previous studies, estrogen has been demonstrated to possess widely regulatory effects on potassium channels. Here, the effect of 17-β-estradiol on modulating inwardly rectifying K(+) (Kir) currents was investigated in cultured hippocampal neurons...

Neurotrophin 3 (NT-3) is an important factor for promoting prenatal neural development, as well as regeneration, axogenesis and plasticity in postnatal life. Therapy with NT-3 was reported to improve the condition of patients suffering from degenerative diseases and traumatic injuries, however, the disadvantage of NT-3 protein delivery is its short half-life, thus our alternative approach is the use of NT-3 gene therapy. In this study, the bone marrow stromal cells (BMSCs) were isolated from adult rats, cultured for 4 passages and transfected with either pEGFP-N1 or a constructed vector containing murine proNT-3 (pSecTag2/HygroB-murine proNT-3) using Lipofectamine 2000 followed by Hygromycin B (200mg/kg)...

Activation of hepatic stellate cells (HSCs) plays a pivotal role in the development of liver fibrosis. C1q/tumor necrosis factor-related protein 3 (CTRP3), a member of CTRPs, was involved in fibrosis. However, little is known about the role of CTRP3 in liver fibrosis. This study aimed to determine its role in liver fibrosis and explore the possible mechanism. Our results demonstrated that CTRP3 was lowly expressed in liver fibrosis tissues and activated HSCs. Overexpression of CTRP3 inhibited the proliferation and migration of HSCs, as well as suppressed the expression of extracellular matrix (ECM) in transforming growth factor-β1 (TGF-β1)-stimulated HSC-T6 cells...

The molecular mechanisms underlying the growth and metastasis of colorectal cancer (CRC) remain largely unknown. Sulfatase-2 (SULF2) was found to play critical roles in human cancers. Recent study reported that SULF1/2 overexpression resulted in increased viability and proliferation, and augmented cell migration in CRC cells. However, the expression of SULF2 and its underlying molecular mechanisms in CRC remain unknown. In this study, we found that the expressions of SULF2 in CRC tissues and cell lines were significantly increased compared to control groups...

Methanol-induced retinal toxicity, frequently associated with elevated free radicals and cell edema, is characterized by progressive retinal ganglion cell (RGC) death and vision loss. Previous studies investigated the effect of photomodulation on RGCs, but not the visual cortex. In this study, the effect of 670nm Light-Emitting Diode (LED) therapy on RGCs and visual cortex recovery was investigated in a seven-day methanol-induced retinal toxicity protocol in rats. Methanol administration showed a reduction in the number of RGCs, loss of neurons (neuronal nuclear antigen, NeuN+), activation of glial fibrillary acidic protein (GFAP+) expressing cells, suppression of brain-derived neurotrophic factor (BDNF+) positive cells, increase in apoptosis (caspase 3+) and enhancement of nitric oxide (NO) release in serum and brain...

BACKGROUND AND PURPOSE: Doxorubicin (DOXO) is a highly effective anticancer drug but its clinical application is impeded by cardiotoxicity. Asymptomatic diastolic dysfunction can be the earliest manifestation of DOXO cardiotoxicity. Therefore, a search for therapeutic intervention that can interfere with early manifestations and possibly prevent late cardiotoxicity is warranted. Increased DOXO-dependent reactive oxygen species may explain, in part, Ca(2+) and Na(+) overload that contributes to diastolic dysfunction and development of heart failure...

Widespread presence of cadmium in soil and water systems is a consequence of industrial and agricultural processes. Subsequent accumulation of cadmium in food and drinking water can result in accidental consumption of dangerous concentrations. As such, cadmium environmental contamination poses a significant threat to human health. Development of microbial biosensors, as a novel alternative method for in situ cadmium detection, may reduce human exposure by complementing traditional analytical methods. In this study, a multiplex cadmium biosensing construct was assembled by cloning a single-output cadmium biosensor element, cadRgfp, and a constitutively expressed mrfp1 onto a broad-host range vector...

Our work in Sprague Dawley rats has shown rapid alterations in neuroimmune gene expression (RANGE) in the hippocampus and paraventricular nucleus of the hypothalamus (PVN). These manifest as increased interleukin (IL)-6 and IκBα, and suppressed IL-1β and tumor necrosis factor alpha during acute ethanol intoxication. The present studies tested these effects across the lifespan (young adulthood at 2-3 months; senescence at 18 and 24 months), as well as across strain (Fischer 344) and sex. The hippocampus revealed age-dependent shifts in cytokine expression (IL-6, IL-1β, and monocyte chemoattractant protein 1), but no changes were observed in the PVN at baseline or following ethanol...
