BACKGROUND Hypermethylation of the promoter region of the RAS association domain family 1A gene (RASSF1A) occurs widely in hepatocellular carcinoma (HCC) tissues. While the diagnostic performance of the use of RASSF1A methylation as a serum or plasma marker in patients with HCC has varied largely in the literature,we confirmed the clinical application value of serum RASSF1A methylation for HBV ...
This study assessed the clinical efficacy of the neoadjuvant chemotherapy TAC scheme in treatment of patients with locally advanced breast cancer, and the value of the level of Ras association domain family 1A (RASSF1A) gene methylation and the Wnt inhibitory factor (WIF)-1 gene in tissue and serum of patients in clinical outcome prediction. In total, 126 patients were consecutively selected to...
As the most lethal gynecological malignancy, ovarian cancer has attracted much attention over the past few decades; however, the early detection of this malignancy has been largely unsuccessful. The aim of this study was to determine the effects of Ras-association domain family 1, isoform A (RASSF1A) on ovarian cancer and to elucidate the molecular mechanisms responsible for these effects. The ...
Background: Epigenetic silencing of the RAS association domain family 1A (RASSF1A) tumor suppressor gene promoter has been demonstrated in renal cell carcinoma (RCC) as a result of promoter hypermethylation. Contradictory results have been reported for RASSF1A methylation in normal kidney, thus it is not clear whether a significant difference between RASSF1A methylation in normal and tumor cell...
Ras association domain family 1A (RASSF1A) is one of the most epigenetically silenced elements in human cancers. Localized on chromosome 3, it has been demonstrated to be a bone fide tumor suppressor influencing cell cycle events, microtubule stability, apoptosis, and autophagy. Although it is epigenetically silenced by promoter-specific methylation in cancers, several somatic nucleotide change...
The epigenetic inactivation of tumor suppressor genes may play an important role in the development and progression of many cancer types, including lung cancer. Therefore, we investigated the association between the aberrant promoter methylation of 2 genes: the Death-Associated Protein Kinase (DAPK) and the Ras Association Domain Family 1A (RASSF1A) by using methylation-specific PCR, and the cl...
BACKGROUND The purpose of this study was to investigate the prognostic significance of methylation of RAS association domain family protein 1 (RASSF1A) in the promoter region for patients with stage II and III colorectal cancer (CRC) receiving oxaliplatin-based chemotherapy. MATERIAL AND METHODS There were 108 eligible CRC patients and 78 healthy controls included in this study. Methylation-spe...
Penile Squamous Cell Carcinoma (SCC) is a rare cancer with poor prognosis and limited response to conventional chemotherapy. The genetic and epigenetic alterations of Epidermal Growth Factor Receptor (EGFR)-RAS-RAF signaling in penile SCC are unclear. This study aims to investigate four key members of this pathway in penile SCC. We examined the expression of EGFR and RAS-association domain fami...
Breast cancer, the most common malignancy in women, emerges through a multistep process, encompassing the progressive sequential evolution of morphologically distinct stages from a normal cell to hyperplasia (with and without atypia), carcinoma in situ, invasive carcinoma and metastasis. The success of treatment of breast cancer could be greatly improved by the detection at early stages of canc...
