Mutation Analysis of TP53 Tumor Suppressor Gene in Colorectal Cancer in Patients from Iran (Kerman Province)
Objective(s) P53 is an important tumor suppressor, which is mutated in later stages of many cancers and leads to resistance to chemotherapy. The aim of this study was to reveal mutations of TP53 in colorectal cancer in Kerman province. Materials and Methods A total of Forty-three colon cancer specimens as paraffin block or fresh tissues, which passed stage IIIA, were selected. Three exons 5,...
متن کاملSOX7: from a developmental regulator to an emerging tumor suppressor.
SOX7 belongs to the SOX (SRY-related HMG-box) family of transcription factors that have been shown to regulate multiple biological processes, such as hematopoiesis, vasculogenesis and cardiogenesis during embryonic development. Recent studies indicate that several SOX family members play important roles in tumorigenesis. In this review, we introduce SOX7 gene and protein structures, and discuss...
متن کاملDNA methylation of tumor suppressor genes in hepatocellular carcinoma
The basic unit of chromatin is a nucleosome included an octamer of the four core histones and 147 base pairs of DNA. Posttranslational histones modifications affect chromatin structure resulting in gene expression changes. CpG islands hypermethylation within the gene promoter regions and the deacetylation of histone proteins are the most common epigenetic modifications. The aberrant patterns of...
متن کاملA candidate tumor suppressor gene, H37, from the human lung cancer tumor suppressor locus 3p21.3.
Frequent allelic loss and homozygous deletions within chromosome 3p in human lung cancers have suggested that the 3p21.3 (370-kb) region contains a critical tumor suppressor gene(s) (TSG). With the exact identity/characteristics of such a gene(s) still unconfirmed, a lack of inactivating structural mutations in the expressed genes contained within this region may indicate that the 3p TSG(s) do ...
متن کاملThe RASSF1A tumor suppressor.
RASSF1A (Ras association domain family 1 isoform A) is a recently discovered tumor suppressor whose inactivation is implicated in the development of many human cancers. Although it can be inactivated by gene deletion or point mutations, the most common contributor to loss or reduction of RASSF1A function is transcriptional silencing of the gene by inappropriate promoter methylation. This epigen...
