Recent evidence indicates that small noncoding RNA molecules known as microRNAs (miRNAs) can function as tumor suppressors and oncogenes. Mutation, misexpression, and altered mature miRNA processing are implicated in carcinogenesis and tumor progression. Because SNPs in pre-miRNAs could alter miRNA processing, expression, and/or binding to target mRNA, we(More)
Small, noncoding RNA molecules, called microRNAs (miRNAs), are thought to function as either tumor suppressors or oncogenes. Common single-nucleotide polymorphisms (SNPs) in miRNAs may change their property through altering miRNA expression and/or maturation, and thus they may have an effect on thousands of target mRNAs, resulting in diverse functional(More)
microRNAs (miRNA) are a new class of non-protein-coding, small RNAs that function as tumor suppressors or oncogenes. They participate in diverse biological pathways and function as gene regulators. Recently, we conducted a survey of common single nucleotide polymorphisms (SNP) in miRNA sequences and reported that, among four SNPs (rs2910164, rs2292832,(More)
Fibroblast growth factor receptor 2 (FGFR2) belongs to the FGFR family, which plays an important role in cell growth, invasiveness, motility and angiogenesis. In human breast cancer, expression of FGFR2 is estrogen receptor (ER)-dependent and correlates with a lower rate of apoptosis. Recently, whole-genome association studies have identified several(More)
Antitumor T lymphocytes play a pivotal role in immunosurveillance of malignancy. The CTL antigen 4 (CTLA-4) is a vital negative regulator of T-cell activation and proliferation. This study examined whether genetic polymorphisms in CTLA-4 are associated with cancer susceptibility. A two-stage investigation using haplotype-tagging single nucleotide(More)
PURPOSE Accumulative evidence suggests that interleukin-12 (IL-12) plays a central role in the Th1 responses and thus participates in the carcinogenesis of human papillomavirus-related cervical cancer. We hypothesized that potentially functional polymorphisms in IL12A and IL12B may individually and jointly contribute to cervical cancer risk. EXPERIMENTAL(More)
PURPOSE The PALB2 gene has an essential role in BRCA2-mediated DNA double-strand break repair and intra-S phase DNA damage checkpoint control, and its mutations are moderately associated with breast cancer susceptibility. This study was designed to investigate the common variants of PALB2 and their association with breast cancer risk. EXPERIMENTAL DESIGN(More)
OBJECTIVE Laminin-5 is required in RAS and NF-kappaB blockade induced tumorigenesis of human squamous cell carcinoma and a marker of invasiveness in cervical lesions. MicroRNA-218 (miR-218) can target laminin-5 beta3 (LAMB3), but suppressed by HPV-16 E6 protein. Therefore, we hypothesized that single nucleotide polymorphisms (SNPs) in pri-miR-218 and LAMB3(More)
Lung adenocarcinomas are more commonly associated with brain metastases (BM). Epidermal growth factor receptor (EGFR) mutations have been demonstrated to be both predictive and prognostic for patients with lung adenocarcinoma. We aimed to explore the potential association between EGFR mutation and the risk of BM in pulmonary adenocarcinoma patients. Data of(More)
Long-term human papillomavirus (HPV) infection is a prerequisite for cervical cancer. IL-1β and IL-1Ra expression levels play an important role in cervical carcinogenesis. Several functional genetic variants in IL1B and IL-RN have been reported to be associated with IL-1β expression and cancer susceptibility. In the current study, we hypothesized that(More)
