(author), Goldbohm, R.A. (author), Schalken, J.A. (author), van den Brandt, P.A. (author)We investigated whether smoking is associated with mutations in the Von Hippel-Lindau (VHL) gene in 337 cases of sporadic renal cell carcinoma (RCC) among 120 852 people followed for 11.3 years; the findings suggest that smoking causes RCC independently of VHL gene mutations. © 2006 Cancer Research.

(author), Groot, J.de (author), Roberts, S. (author), Maroudas, A. (author)We have used the racemization of aspartic acid as a marker for the "molecular age" of aggrecan components of the human intervertebral disc matrix (aggregating and non-aggregating proteoglycans as well as the different buoyant density fractions of aggrecan). By measuring the D/L Asp ratio of the various aggrecan species as a function of age and...article 2006

The apoE isoforms circulate in different plasma concentrations, but plasma concentrations of the same isoform also differ between individuals. Whereas the isoforms have been associated with cardiovascular disease,...article 2006

(author)Alcohol has been hypothesized to promote ovarian carcinogenesis by its potential to increase circulating levels of estrogen and other hormones; through its oxidation byproduct, acetaldehyde, which may act as a cocarcinogen; and by depletion of folate and other nutrients. Case-control and cohort studies have reported conflicting results relating...article 2006
