OBJECTIVE To investigate the effect of endogenous brain derived neurotrophic factor (BDNF) on GAP-43 expression in the anterior horn of the spinal cord in rats following sciatic nerve injury. METHODS BDNF antibody was injected intraperitoneally in rats with crushing injury of the sciatic nerve, and the control rats received normal saline only after(More)
The mood stabilizers lithium, valproate and lamotrigine are traditionally used to treat bipolar disorder. However, accumulating evidence suggests that these drugs have broad neuroprotective properties and may therefore be promising therapeutic agents for the treatment of neurodegenerative diseases, including stroke. Lithium, valproate and lamotrigine exert(More)
BACKGROUND Recent studies have linked chemotherapy resistance to the altered expression of microRNAs (miRNAs). Thus, miRNA-based approaches to modulating sensitivity to temozolomide (TMZ) may overcome chemoresistance. The aim of the present study was to investigate whether miR-136 could modulates glioma cell sensitivity to TMZ. METHODS The proliferation(More)
In order to reduce the dimensionality of feature vector space and reduce the computing complexity of categorization, each document of the train set is summarized automatically and two approaches to text categorization based on these summaries are proposed: in the first approach, the text summarization is directly used for feature selection and(More)
To investigate the underlying molecular mechanisms of pituitary tumor by using the microarray expression profiles of pituitary tumor and normal tissue samples. The gene expression profile of GSE26966 was downloaded from Gene Expression Omnibus, including nine normal samples and 14 pituitary tumor samples. The differentially coexpressed genes (DEGs) were(More)
miR-132 was found to be overexpressed in glioma; however, its clinical significance has not been investigated. In the present study, we evaluated the association between miR-132 and clinicopathological parameters and prognosis. Quantitative real-time PCR was used to analyze the expression of miR-132 in 113 cases of glioma and 36 cases of normal brain(More)
Chemotherapy drugs themselves may act as stressors to induce adaptive responses to promote the chemoresistance of cancer cells. Our previous research showed that sirtuin 1 (SIRT1) was overexpressed in pancreatic cancer patients and deregulation of SIRT1 with RNAi could enhance chemosensitivity. Thus, we hypothesized that SIRT1 might facilitate(More)
