Second primary cancers after sporadic and familial colorectal cancer.
Second cancers were studied among 68,104 cases of colorectal cancer (CRC) from the Swedish Family-Cancer Database. A total of 1,113 patients received a diagnosis of second CRC; 25 of them had a family history of CRC. Cases of second CRC with a family history were diagnosed up to 10 years before sporadic cases. The relative risk (RR) of all second CRCs was 2.21 compared with the first CRC. Famil...
متن کاملMolecular pathogenesis of sporadic colorectal cancers
Colorectal cancer (CRC) results from the progressive accumulation of genetic and epigenetic alterations that lead to the transformation of normal colonic mucosa to adenocarcinoma. Approximately 75% of CRCs are sporadic and occur in people without genetic predisposition or family history of CRC. During the past two decades, sporadic CRCs were classified into three major groups according to frequ...
متن کاملCopy number abnormalities in sporadic canine colorectal cancers.
Human colorectal cancer (CRC) is one of the better-understood systems for studying the genetics of cancer initiation and progression. To develop a cross-species comparison strategy for identifying CRC causative gene or genomic alterations, we performed array comparative genomic hybridization (aCGH) to investigate copy number abnormalities (CNAs), one of the most prominent lesion types reported ...
متن کاملSubstrate-specific inhibition of RecQ helicase.
The RecQ helicases constitute a small but highly conserved helicase family. Proteins in this family are of particular interest because they are critical to maintenance of genomic stability in prokaryotes and eukaryotes. Eukaryotic RecQ helicase family members have been shown to unwind not only DNA duplexes but also DNAs with alternative structures, including structures stabilized by G quartets ...
متن کاملAltered expression of Lnc-OC1 and SIRT1 genes in colorectal cancer tissue
Backgrounds: SIRT1 plays an important role in many physiological processes, including metabolism, neuronal protection, senecence and inflammatory, by staging histones and multiple transcription factors. However, the complex mechanisms of SIRT1 signaling in tumors are not yet fully understood, as it acts as both an oncogen and a tumor suppressor. On the other hand, it has been shown that the Lnc...
