Expression of mismatch repair proteins in invasive and in situ carcinoma of the breast.
BACKGROUND Genetic instability is a characteristic feature of familial and sporadic breast carcinomas. It is not clear whether defects in the mismatch repair system accompany this instability. The purpose of this study was to explore the expression of two of the proteins encoded by the DNA mismatch repair genes, namely MLH1 and MSH2, in sporadic in situ and invasive breast carcinomas of various...
متن کاملBRAF mutation in endometrial carcinoma and hyperplasia: correlation with KRAS and p53 mutations and mismatch repair protein expression.
PURPOSE Although several gene abnormalities have been reported in endometrial carcinoma, the genetic alterations have not fully been elucidated. Recent studies have revealed frequent activating mutations of the gene for BRAF, an effector of Ras protein in the mitogen-activated protein kinase pathway, in several malignancies. However, the prevalence and significance of BRAF mutations in endometr...

متن کاملMismatch repair genes expression defects & association with clinicopathological characteristics in colorectal carcinoma
BACKGROUND & OBJECTIVES DNA mismatch repair gene (MMR) abnormalities are seen in 95 per cent of hereditary nonpolyposis colorectal cancer (HNPCC) and 10-15 per cent of sporadic colorectal cancers. There are no data on MMR abnormalities in Malaysian colorectal cancer patients. This study was aimed to determine the frequency of abnormal MMR gene protein expression in colorectal carcinoma in North...
متن کاملPancreatic ascariasis with periampullary carcinoma
Ascarias lumbricoides infestation is endemic in tropical countries. Most infections are asymptomatic, but it can produce a wide spectrum of manifestations including hepatobiliary and pancreatic complications. There are reports of association of biliary ascariasis with bilary malignancies in the past, but same is not known for pancreatic ascariasis. We report a case of association of periampulla...
