BACKGROUND & OBJECTIVE Matrix metalloproteinases (MMPs) play an important role in invasion and metastasis of cancers. CD147, an inducer of MMPs, can activate the expression of multiple MMPs in cancer cells and interstitial cells. This study was to investigate the correlations of CD147 and MMP-2 expressions in tumor and adjacent tissue to metastasis,(More)
BACKGROUND & OBJECTIVE Deletions and translocations involving the short arm of chromosome 3 (3p14) have been observed frequently in esophageal cancer. Fragile histidine triad (FHIT) gene is located in 3p14.2, and its deletion or abnormal expression was found in many kinds of cancers. The study was to investigate the alterations of FHIT gene, and its(More)
AIM To study the relationship between Survivin and PTEN expression and lymph node metastasis, depth of invasion and prognosis of gastric cancer patients in China. METHODS Specimens of gastric cancer tissue were collected from the Affiliated Hospital of Jianghan University. All the 140 patients had complete examination data. All lymph nodes were found by(More)
Epidemiological evidence suggests that cigarette smoke induces squamous metaplasia in human tracheobronchial epithelium that can progress to lung squamous carcinoma. But it is not well understood how tracheobronchial epithelial cells transduce the signals that mediate cigarette smoke-induced squamous differentiation or squamous metaplasia. In the present(More)
AIM To evaluate whether the combination of recombinant chicken fibroblast growth factor receptor-1 (FGFR-1) protein vaccine (cFR-1) combined with low-dose gemcitabine would improve anti-tumor efficacy in a mouse CT26 colon adenocarcinoma (CT26) model. METHODS The CT26 model was established in BABL/c mice. Seven days after tumor cell injection, mice were(More)
BACKGROUND & OBJECTIVE p53 gene plays an important role in regulating cell cycle, maintaining completeness of cellular genomes, inducing cell differentiation and apoptosis. p53 gene mutation occurs usually in gliomas, especially astrocytomas. This study was to investigate p53 gene mutation and its correlation to the development of glioma. METHODS p53 gene(More)
To investigate the roles of glycogen synthase kinase 3beta (GSK3beta) and adenomatous polyposis coli (APC) protein in wound repair of airway epithelial cells (AECs), we established a wound model of airway epithelium in vitro. Then the following tests were undertaken: (1) Western blot was used to detect the levels of total GSK3beta and phosphorylated(More)
BACKGROUND & OBJECTIVE Being downstream targets of the phosphatase and tensin homolog deleted on chromosome ten (PTEN) and epidermal growth factor receptor (EGFR) pathways, serine/threonine kinase AKT, nuclear factor-kappaB (NF-kappaB) and signal transducer and activator of transcription-3 (STAT3), play important roles in cell proliferation, apoptosis and(More)
The effect of glycogen synthase kinase 3beta (GSK3beta) has been repeatedly implicated in cell proliferation, but studies on the effect of GSK3beta in different cell lines with different stimuli have drawn different conclusions. To investigate the direct effect of GSK3beta on cell growth in human lung adenocarcinoma cell line A549, we changed its activity(More)
Human MLH1 is one of the DNA mismatch repair genes and located in chromosome 3p21.3. Alterations of the MLH1 were associated with various kinds of human tumors. The present study was to investigate allelic loss of MLH1 and microsatellite instability (MSI) in esophageal squamous cell carcinomas (ESCC), and to estimate the correlation between MSI status and(More)
