To determine the basis for unexpected differences in CYP1A1 inducing potencies and efficacies for the diet-derived indole derivative, indolo[3,2-b]carbazole (ICZ) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), we conducted a systematic analysis of events involved in the induced expression of CYP1A1 in murine hepatoma-derived cell lines (Hepa-1). In(More)
Fructose found in modern diets as a constituent of the disaccharide sucrose is absorbed by a well-characterized absorptive system integrating enzymatic hydrolysis of the disaccharide and transfer of the resulting two monosaccharides through the apical membrane of the epithelial cell. The increasing use of high-fructose syrups and crystalline fructose(More)
To identify susceptibility loci for non-Hodgkin lymphoma subtypes, we conducted a three-stage genome-wide association study. We identified two variants associated with follicular lymphoma at 6p21.32 (rs10484561, combined P = 1.12 x 10(-29) and rs7755224, combined P = 2.00 x 10(-19); r(2) = 1.0), supporting the idea that major histocompatibility complex(More)
The current options for treating breast cancer are limited to excision surgery, general chemotherapy, radiation therapy, and, in a minority of breast cancers that rely on estrogen for their growth, antiestrogen therapy. The naturally occurring chemical indole-3-carbinol (I3C), found in vegetables of the Brassica genus, is a promising anticancer agent that(More)
Studies have linked the consumption of broccoli and other cruciferous vegetables to a reduced risk of breast cancer. The phytochemical indole-3-carbinol (I3C), present in cruciferous vegetables, and its major acid-catalyzed reaction product 3,3'-diindolylmethane (DIM) have bioactivities relevant to the inhibition of carcinogenesis. In this study, the effect(More)
Diffuse large B cell lymphoma (DLBCL) is the most common lymphoma subtype and is clinically aggressive. To identify genetic susceptibility loci for DLBCL, we conducted a meta-analysis of 3 new genome-wide association studies (GWAS) and 1 previous scan, totaling 3,857 cases and 7,666 controls of European ancestry, with additional genotyping of 9 promising(More)
We investigated the mechanism of ligand-independent activation of the estrogen receptor (ER) by 3,3'-diindolylmethane (DIM), a promising anticancer agent derived from vegetables of the Brassica genus, in Ishikawa and HEC-1B human endometrial cancer cells. DIM stimulated the activity of an ER-responsive reporter by over 40-fold, equivalent to the maximum(More)
Genome-wide association studies (GWAS) have previously identified 13 loci associated with risk of chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL). To identify additional CLL susceptibility loci, we conducted the largest meta-analysis for CLL thus far, including four GWAS with a total of 3,100 individuals with CLL (cases) and 7,667 controls.(More)
Previous studies have shown that the absorption of fructose is aided by simultaneous ingestion of glucose. The aim of the present study was to reproduce this finding in vitro to better understand the mechanism of the effect of glucose on absorption of fructose. The phenomena could not be reproduced with everted sleeves of rat intestine or brush border(More)
Indole-3-carbinol (I3C), a naturally occurring compound of Brassica vegetables, has promising anticancer properties and activates an anti-proliferative pathway that induces a G1 cell cycle arrest of human breast cancer cells. A microarray analysis of I3C treated versus untreated MCF-7 breast cancer cells revealed that I3C increased expression of the(More)
