Chemokines play an important role in the pathogenesis of non-small cell lung cancer (NSCLC). However, aberrant methylation of CXCL12 has not been examined in NSCLC. CXCL12 mRNA expression and methylation were examined in 17 NSCLC cell lines by RT-PCR and methylation-specific PCR (MSP). MSP was performed on 236 tumor specimens from NSCLC patients who received curative intent surgery. CXCL12 and ...
BACKGROUND To identify genes associated with hepatocellular carcinoma (HCC) pathogenesis, we developed a triple combination array strategy comprising methylation, gene expression, and single nucleotide polymorphism (SNP) array analysis. METHODS Surgical specimens obtained from a 68-year-old female HCC patient were analyzed by triple combination array, and identified Dynamin 3 (DNM3) as a cand...
Expression of the cadherin family member CDH13 (H-cadherin) is reduced in several human tumors, and it has been hypothesized that this gene functions as a tumor suppressor gene. Previously, we reported that the 5' region of CDH13 is frequently methylated in breast and lung cancers. Here we confirmed the promoter activity of 5' region of CDH13 by luciferase assay and examined its aberrant methyl...
Background and Objective: The DBC2 (deleted in breast cancer 2) or RhoBTB2 (Located on 8p21) is a tumor suppressor gene associated with tumorigenesis. Mutational studies of DBC2 at its promoter region in breast cancer revealed an important role for epigenetic changes contributing to its low expression. Epigenetic changes through hypermethylation of the promoter can cause the inactivation of DBC...
بررسی اثر سولفورموستارد بر وضعیت متیلاسیون پروموتر ژن FOXP3 در جانبازان شیمیایی با عوارض تأخیری ریوی
Background and Objective: Sulfur mustard (SM) is a toxic and chemical agent. The incidence of pulmonary complications and inflammatory processes play an important role in SM-exposed individuals. FOXP3 is one of the important factors in the development of chronic pulmonary diseases. FOXP3 gene promoter due to exposure to chemical and toxic materials leads to chronic pulmonary disease. In this st...
OBJECTIVE Mechanism of zoledronic acid on osteoblastic differentiation of mesenchymal stem cells (MSCs) has not fully understood. With the knowledge of some drugs mechanism that alter methylation pattern of some genes, the present research sets out to evaluate osterix (OSX) promoter methylation pattern during zoledronic acid-induced osteoblastic differentiation of MSCs. MATERIALS AND METHODS ...
This study was aimed at defining patterns of aberrant gene methylation in non-small cell lung cancer (NSCLC) in Chinese patients and its use in detecting cancer cells in bronchoalveolar lavage (BAL). The methylation-specific PCR (MSP) was used to study methylation of the p16, retinoic acid receptor-beta (RARbeta), death-associated protein (DAP) kinase, and O(6)-methylguanine-DNA-methyltransfera...
MOTIVATION DNA methylation is an epigenetic mechanism of gene regulation. Bisulfite- conversion-based PCR methods, such as bisulfite sequencing PCR (BSP) and methylation specific PCR (MSP), remain the most commonly used techniques for methylation mapping. Existing primer design programs developed for standard PCR cannot handle primer design for bisulfite-conversion-based PCRs due to changes in ...
background and objective: the dbc2 (deleted in breast cancer 2) or rhobtb2 (located on 8p21) is a tumor suppressor gene associated with tumorigenesis. mutational studies of dbc2 at its promoter region in breast cancer revealed an important role for epigenetic changes contributing to its low expression. epigenetic changes through hypermethylation of the promoter can cause the inactivation of dbc...
OBJECTIVE The present study was conducted to elucidate the prognostic prediction value of the methylation of the RASSF10 promoter in gastric cancer (GC). METHODS A total of 300 patients with GC revealed the methylation degrees of the DNA of the RASSF10 promoter. Methylation-specific PCR (MSP) analysis was performed to qualitatively detect the methylated degrees of the DNA of the RASSF10 promo...
