The effective treatment for cerebral ischemia has not yet been established. Hepatocyte growth factor (HGF) is a potent pleiotropic cytokine that is involved in cell and tissue regeneration, including in the central nervous system. Studies have demonstrated that an exogenous administra­tion of HGF protects brain tissue from ischemic damage. In response to binding to the receptor cMet, HGF activates the downstream signaling pathways (including the phospha­tidylinositol 3-kinase/Akt, Ras/MAPK and signal transducer and activator of transcription pathways) which leads to various cellular responses involved in angiogenesis, glial scar forma­tion, antiapoptosis and neurogenesis. The purpose of this review is to summarize the present understanding of the thera­peutic potential of HGF in cerebral ischemia. © 2015, Spandidos Publications. All rights reserved.

Source of support: Departmental sources Background: The aim of this study was to evaluate the effect of when silencing HOTAIR in ovarian cancer skov3 cells on proliferation, migration, and invasion, and to elucidate the mechanism by which this occurs. Material/Methods: We detected the mRNA level of HOTAIR (HOX antisense intergenic RNA) and MAPK1 (mitogen-activated protein kinase 1) in ovarian cancer SKOV3, ES-2, OVCAR3, A2780, and COC1 cell lines. We detected the mRNA level of HOTAIR and MAPK1 in ovarian SKOV3 when transected with miR-1, miR-214-3p, or miR-330-5p. We detected the mRNA and protein level of MAPK1 when silencing HOTAIR. We detected the expression of HOTAIR when silencing MAPK1. Then we detected the proliferation, migration, and invasion in ovarian cancer skov3 after silencing HOTAIR or MAPK1. Results: The expression of HOTAIR and MAPK1 in ovarian SKOV3, ES-2, and OVCAR3 increased compared with A2780 and COC1 cells (P<0.05). The mRNA level of HOTAIR and MAPK1 in ovarian SKOV3 decreased when transected with miR-1, miR-214-3p, or miR-330-5p compared to negative control (p<0.05). The mRNA and protein level of MAPK1 was decreased when silencing HOTAIR and the mRNA level of HOTAIR was decreased when silencing MAPK1 (p<0.05). The proliferation, migration, and invasion was inhibited in ovarian SKOV3 after silencing HOTAIR or MAPK1 (p<0.05). Conclusions: HOTAIR can promote proliferation, migration, and invasion in ovarian SKOV3 cells as a competing endogenous NA. © Med Sci Monit, 2015.

Infantile spasms are a severe epileptic encephalopathy with a variety of etiologies that occur in infancy and early childhood. Subjects with infantile spasms are at a higher risk for evolving into intractable epileptic spasms, tending to be refractory to conventional antiepileptic drugs. Genetic polymorphisms of the P-glycoprotein-encoding gene ABCB1 are suspected to be associated with pharmacoresistance phenotypes in epilepsy patients. Conflicting findings have been reported in different populations; few studies have explored whether this apparent association is affected by other host factors, such as specific epilepsy syndrome. We performed a case-control study to determine whether the risk of infantile spasms is influenced by common ABCB1 polymorphisms in a Han Chinese children’s population consisting of 91 patients and 368 healthy individuals. DNA was isolated from whole blood, and three genetic polymorphisms (C1236T, G2677T/A, and C3435T) were assayed by PCR-RFLP. There were significant differences in the distributions of 3435TT [P = 0.001; odds ratio = 2.47; 95% confidence interval (CI) = 1.44-4.27] and 3435CT [P < 0.001; odds ratio = 0.28; 95%CI = 0.15-0.54] genotypes between infantile spasm cases and controls. No significant differences were observed in allelic and haplotypic frequencies of ABCB1 polymorphisms between the two groups. This study demonstrated that variations in the C3435T gene play an important role in the pathogenesis of infantile spasms in the Han Chinese population; 3435TT is associated with increased risk of having this epilepsy syndrome. © FUNPEC-RP.

We evaluated the relationship between total serum immunoglobulin E (IgE) levels and pregnancy outcome in a prospective cohort study focusing on fetal growth restriction (FGR). Sixty women with FGR and twenty with normal singleton pregnancy were enrolled during their third trimester. Infants were followed up for 6 months. Blood samples were obtained from pregnant women during the third trimester; cord blood samples were also taken. Six months after birth, blood samples were obtained from infants. Demographic and baseline characteristics were compared between groups. Birth weight, length and head circumference of neonates in the FGR group were lower than those in the control group. Total serum IgE level was significantly increased in third-trimester pregnant women with FGR compared with normal group (P < 0.05). However, this trend was not observed in the cord blood at birth or peripheral blood of 6-month-old infants. The prevalence of atopic eczema between the 2 groups was similar. Linear regression analysis revealed that the IgE level in the third trimester was negatively correlated with birth weight (P < 0.05). Higher serum IgE level in the cord blood was signifcantly associated with an increased risk of being small for gestational age (P < 0.05). In conclusion, IgE levels in the third trimester of pregnancy and cord blood are strongly related to birth outcomes of FGR. © FUNPEC-RP
