Prevalence of K-RAS mutations and CA125 tumor marker in patients with ovarian carcinoma
Background: Ovarian carcinoma is one of the leading causes of cancer-related death among females. K-ras codon 12 mutations are commonly occurring mutations in different types of cancers and leads to resistance against anti-EGFR therapeutics. Hence, determination of mutations in k-ras gene is crucial for predicting response to anti-EGFR therapies. This study aimed to evaluate the prevalence of k...
متن کاملK-Ras and H-Ras Activation Promote Distinct Consequences
A considerable amount of evidence indicates that Ras signaling contributes to the development of endometrial cancer. We previously demonstrated that endometrial cancer cells carrying oncogenic [Val]K-ras were susceptible to apoptosis. The present study examined the role of K-and H-Ras in the induction of apoptosis using rat endometrial cells (RENT4 cells). We found that constitutively activated...
متن کاملK-ras gene mutations in normal colorectal tissues from K-ras mutation-positive colorectal cancer patients.
K-ras gene mutations have been reported as early events in colorectal tumorigenesis, but their role in tumor initiation and development is still unclear. To analyze and compare K-ras mutational patterns between colorectal tissues at different stages of tumor progression in individual patients, 65 colorectal tissue samples, including carcinoma, adenoma, histologically normal mucosa, submucosal m...
متن کاملK-ras and Dpc4 mutations in chronic pancreatitis: case series.
AIM To assess whether alterations in the K-ras, p53, and DPC4 genes are present in pancreatitis, a potential precancerous condition that can progress to pancreatic adenocarcinoma. To investigate the alterations occurring at hot spots of K-ras (exon 1), p53 (exons 5 and 7), and DPC4 (exons 8, 10 and 11). METHODS In 10 patients with acute and 22 with chronic pancreatitis, without pancreatic int...
متن کاملK-ras mutations in stools and tissue samples from patients with malignant and nonmalignant pancreatic diseases.
Mutant-enriched PCR and reverse dot blot hybridization in microplates were applied for examining K-ras status in stools and tissue samples from patients with pancreatic tumors and chronic pancreatitis. In tissue samples, K-ras mutations were found in 32 of 35 cases of ductal adenocarcinoma, in 5 of 7 periampullary cancers, in 1 cystadenocarcinoma, and in 3 of 5 patients with chronic pancreatiti...
