Association of Polymorphisms in the Genes of Angiotensinogen and Angiotensin Receptors With Risk for Basal Cell Carcinoma.

Background/aim: Basal cell carcinoma (BCC) has been genetically associated with an increased expression of angiotensin-converting enzyme (ACE), an important factor of the renin-angiotensin system which produces vasoconstrictor angiotensin II. Other factors of this system include angiotensinogen (AGT) and angiotensin receptors AGTR1, AGTR2. We investigated the possible association of BCC with genetic variability in the AGT, AGTR1 and AGTR2 genes.

Effect of thrombosis-related gene polymorphisms upon oral cancer: a regression analysis.

It is well-known that there is an interplay between hemostasis, thrombosis and cancer. Functional DNA polymorphisms in genes encoding factors related to thrombosis have been associated with increased risk for oral squamous cell carcinoma (OSCC). The present study investigated the possible combinatory effect of 10 such polymorphisms as primary risk predictors for OSCC in a European population.

Association of angiotensin-converting enzyme gene insertion/deletion polymorphism with decreased risk for basal cell carcinoma.

The incidence of basal cell carcinoma (BCC) is significantly reduced in individuals treated with inhibitors of angiotensin I-converting enzyme (ACE) that produces angiotensin II. The objective of this study was to investigate the possible association of a functional polymorphism in the ACE gene, which affects its transcription, with risk for BCC. In DNA samples of 92 patients with BCC and 103 healthy controls of Greek origin and comparable age and gender, we studied the ACE gene insertion/deletion (I/D) polymorphism.
