AIM The cell cycle regulator cyclin D1 (CCND1) is a critical regulator of the G1/S phase transition and plays an important part in several tumor types. This study aimed at investigating the association of CCND1 with and examining the interaction among CCND1 genotype and individual smoking habit in nasopharyngeal carcinoma susceptibility. PATIENTS AND(More)
The aim of this study was to evaluate the association and interaction of genotypic polymorphism in methylenetetrahydrofolate reductase (MTHFR) with smoking habits and oral cancer in Taiwan. Two well-known polymorphic variants of MTHFR, C677T (rs1801133) and A1298C (rs1801131), were analyzed in association with oral cancer risk, and their joint effects with(More)
UNLABELLED The aim of this study was to evaluate the association of polymorphic genotypes in the cyclooxygenase 2 gene (COX2), which is reported to be overexpressed in prostate tumors, with Taiwan prostate cancer patients. MATERIALS AND METHODS Six polymorphic variants of COX2 were analyzed for their association with prostate cancer susceptibility. A(More)
Nasopharyngeal carcinoma (NPC) is a multifactorial type of cancer, and cytokines driving the immune response seem to be disturbed in patients with NPC. Interleukin-10 (IL10) is an immunosuppressive cytokine which may facilitate carcinogenesis by down-regulating interferon-gamma production and supporting tumor escape from the immune response. We propose that(More)
Hepatocellular carcinoma (HCC) is a worldwide neoplasm for which early diagnosis is difficult and the prognosis is usually poor. Overexpression of cyclooxygenase 2 (COX-2) has been suggested to be associated with hepatocarcinogenesis. Although several COX-2 inhibitors have been used in hepatoma therapy, the genetic background between COX-2 and HCC remains(More)
Interleukin-10 (IL10) is an immunosuppressive cytokine which may facilitate carcinogenesis by down-regulating interferon-gamma production and supporting tumor escape from the immune response. Polymorphisms within the promoter of IL10 gene may not only contribute to differential IL10 expression levels among individuals but also to oral cancer susceptibility.(More)
AIM Hepatocellular carcinoma (HCC), the fifth most common cancer worldwide, has high prevalence and mortality rates in Taiwan. Tumor necrosis factor-α (TNFα), an important proinflammatory cytokine, is involved in multiple physiological and pathogenic phenomena that lead to the destruction and dysregulation of tissues. The present study aimed to evaluate the(More)
BACKGROUND/AIM Renal cell carcinoma (RCC) accounts for approximately 3% of all cancer-related mortalities worldwide and the risk factors for the development of RCC have not yet been fully elucidated. Mounting proteomic evidence suggests that inflammatory process plays a role in RCC etiology and interleukin-10 (IL-10) is an important immunosuppressive(More)
AIM Japanese and American groups reported that single nucleotide variation of caveolin-1 gene (CAV1) plays an important role in breast cancer risk. The aim of this study was to evaluate the association of six polymorphic genotypes of CAV1, which is reported to be overexpressed in tumors, with breast cancer within a Taiwanese population. PATIENTS AND(More)
BACKGROUND Caveolin-1 (Cav-1), which has been proposed as a candidate tumor suppressor, plays a regulatory role in several signaling pathways. High expression of Cav-1 in nasopharyngeal carcinoma (NPC) may enhance tumor cell migration and correlate with poor prognosis of the patients, while the genetic alterations of Cav-1 during nasopharyngeal(More)
