Journal ArticleDOI
Analgesic and anti-inflammatory drug use and risk of bladder cancer: a population based case control study
Joan Fortuny,Manolis Kogevinas,Michael S. Zens,Alan R. Schned,Angeline S. Andrew,John A. Heaney,Karl T. Kelsey,Margaret R. Karagas +7 more
TL;DR: An elevated odds ratio was found associated with reported use of phenacetin-containing medications, especially with longer duration of use, and regular use of any NSAID was associated with a statistically significant decrease in bladder cancer risk.
Journal ArticleDOI
Distinct arsenic metabolites following seaweed consumption in humans
Vivien F. Taylor,Zhigang Li,Vicki Sayarath,Thomas J. Palys,Kevin R. Morse,Rachel A. Scholz-Bright,Margaret R. Karagas +6 more
TL;DR: Assessment ofThio-DMAE and thio-DMAA are unique products of arsenosugar breakdown, thus assessment of these compounds may help to identify dietary intake of arsenic from seaweed from other exposure pathways.
Journal ArticleDOI
Distinct patterns of DNA methylation in conventional adenomas involving the right and left colon
Devin C. Koestler,Jing Li,John A. Baron,Gregory J. Tsongalis,Lynn F. Butterly,Martha Goodrich,Corina Lesseur,Margaret R. Karagas,Carmen J. Marsit,Jason H. Moore,Angeline S. Andrew,Amitabh Srivastava +11 more
TL;DR: Results indicate distinct patterns of DNA methylation, independent of CIMP genes, in adenomas of the right and left colon.
Journal ArticleDOI
Expression of tumor suppressive microRNA-34a is associated with a reduced risk of bladder cancer recurrence.
Angeline S. Andrew,Carmen J. Marsit,Alan R. Schned,John D. Seigne,Karl T. Kelsey,Jason H. Moore,Laurent Perreard,Margaret R. Karagas,Lorenzo F. Sempere +8 more
TL;DR: It is demonstrated that a functional tumor suppressive role for miR‐34a in cultured urothelial cells, including reduced matrigel invasion and growth in soft agar, highlights the need for further clinical studies of miR-34a as a guide for recurrence screening and as a possible candidate therapeutic target in the bladder.
Journal ArticleDOI
A case-control study of occupational exposure to metalworking fluids and bladder cancer risk among men
Joanne S. Colt,Melissa C. Friesen,Patricia A. Stewart,Park Donguk,Alison Johnson,Molly Schwenn,Margaret R. Karagas,Karla R. Armenti,Richard Waddell,Castine Verrill,Mary H. Ward,Laura E. Beane Freeman,Lee E. Moore,Stella Koutros,Dalsu Baris,Debra T. Silverman +15 more
TL;DR: Exposure to straight MWFs was associated with a significantly increased bladder cancer risk, as was employment in non-metalworking jobs with possible exposure to mineral oil, which strengthens prior evidence for mineral oil as a bladder carcinogen.
