Chromosome 3p21.3 region is frequently (>90%) deleted in lung and other major human carcinomas. We subdivided 3p21.3 into LUCA and AP20 subregions and discovered frequent homozygous deletions (10-18%) in both subregions. This finding strongly implies that they harbor multiple tumor suppressor genes involved in the origin and/or development of major(More)
RASSF1A, a major member of the RASSF1 gene family, is silenced by promoter methylation at a high frequency in a large number of human solid tumors. Controlled expression of RASSF1A reverts the tumorigenic phenotype of several human cancer cell lines. Here we investigated another main isoform, RASSF1C, and compared it with RASSF1A in the gene inactivation(More)
Near-infrared fluorescence (NIRF) imaging is an attractive modality for early cancer detection with high sensitivity and multi-detection capability. Due to convenient modification by conjugating with moieties of interests, NIRF probes are ideal candidates for cancer targeted imaging. Additionally, the combinatory application of NIRF imaging and other(More)
Bamboo is a kind of biological composite reinforced by unidirectional long fibers. The cleavage strength along grain of bamboo internode is low; however, the existence of bamboo node can hinder the propagation of interlaminar crack to make up for the defect of weak opening mode fracture toughness along interlamination. In this article, the double cantilever(More)
BACKGROUND Previous work has shown reduced expression levels of let-7 in lung tumors. But little is known about the expression or mechanisms of let-7a in prostate cancer. In this study, we used in vitro and in vivo approaches to investigate whether E2F2 and CCND2 are direct targets of let-7a, and if let-7a acts as a tumor suppressor in prostate cancer by(More)
BACKGROUND Many different genetic alterations are observed in cancer cells. Individual cancer genes display point mutations such as base changes, insertions and deletions that initiate and promote cancer growth and spread. Somatic hypermutation is a powerful mechanism for generation of different mutations. It was shown previously that somatic(More)
Initial analysis identified the NPRL2/G21 gene located in 3p21.3C, the lung cancer region, as a strong candidate tumor suppressor gene. Here we provide additional evidence of the tumor suppressor function of NPRL2/G21. The gene has highly conserved homologs/orthologs ranging from yeast to humans. The yeast ortholog, NPR2, shows three highly conserved(More)
To search for a method for treatment of bilateral temporal lobe epilepsy (BTLE), we report one patient with BTLE experienced bilateral stereotactic radiofrequency amygdalohippocampectomy (SAHE). Neuropsychological examinations were performed before and 5 days, and 6, 18, and 48 months after operation. No seizure occurred in the follow-up time, and no(More)
CD147, also named extracelluar matrix metalloproteinase inducer (EMMPRIN), has been proved to be involved in the invasion and metastasis processes of tumor cells in many types of cancers. To determine the role of CD147 in the invasiveness properties of prostate cancer, we successfully downregulated CD147 by RNA interference (RNAi) technology, in PC-3 cell(More)
BACKGROUND LIM and SH3 protein 1 (LASP-1) is a specific focal adhesion protein that is known to be involved in numerous biological and pathological processes. LASP-1 overexpression has been described in several types of cancers, but its expression and role in clear cell renal cell cancer (ccRCC) remains unknown. METHODS Using immunohistochemistry, we(More)
