Ras oncogene mutation in multiple myeloma
The frequency of ras (H-, K-, and N-ras) and c-myc oncogenes was investigated in multiple myeloma (MM). By means of the polymerase chain reaction (PCR)/oligonucleotide hybridization method, DNA from 56 tumor biopsies was analyzed for the presence of activating mutations involving codons 12 and 61 of the H-, K-, and N-ras genes and codon 13 of the N-ras gene. Mutations, involving the N- or K-ras...
متن کاملConcurrent mutation in exons 1 and 2 of the K-ras oncogene in colorectal cancer.
The K-ras gene is frequently mutated in colorectal cancer and has been associated with tumor initiation and progression; approximately 90% of the activating mutations are found in codons 12 and 13 of exon 1 and just under 5% in codon 61 located in exon 2. These mutations determine single aminoacidic substitutions in the GTPase pocket leading to a block of the GTP hydrolytic activity of the K-ra...
متن کاملK-ras Mutation in Colorectal Cancer, A Report from Southern Iran
There are very few studies about K-ras mutations in colorectal cancer (CRC) from developing countries such as Iran. It is therefore essential to conduct studies to learn about the molecular signature of such tumors, allowing the determination of an appropriate management plan. In the present study, we aimed to determine the frequency and types of K-ras mutations among patients with CRC in Iran....
متن کاملMutation of RAS oncogene in atomic bomb radiation-exposed leukemia.
To determine what the role of RAS oncogene is in radiation-induced leukemia, we investigated the frequency of mutations and the sites of the base substitution of activated N- and K-RAS oncogenes in 25 leukemic patients who had been exposed to the atomic bomb and compared the results with those for 47 non-exposed leukemic patients. To detect the presence of mutated RAS oncogene, we used the PCR ...
متن کاملClinical significance of K-ras oncogene activation in ampullary neoplasms.
AIMS To investigate the prevalence of K-ras codon 12 point mutations in ampullary neoplasms, to explore their clinical usefulness, and to test whether the detection of these mutations could be used to identify ampullary malignancies at an early stage. METHODS Forty one tumour specimens from 28 patients with ampullary neoplasms were analysed for activating point mutations in K-ras codon 12 usi...
