OBJECTIVE To determine the efficacy of anti-tumor necrosis factor therapy (etanercept) for treating endometriosis in baboons. DESIGN A randomized, placebo-controlled, blinded study using the baboon endometriosis model. SETTING Southwest National Primate Research Center. ANIMAL(S) Twelve female baboons with spontaneous peritoneal endometriosis. (More)
There is extensive knowledge of androgen receptor (AR) signaling in cancer cells, but less regarding androgen action in stromal cells of the tumor microenvironment. We report here the genome-wide effects of a stromal cell specific molecular adapter and AR coregulator, hydrogen peroxide-inducible gene 5 (Hic-5/TGFB1I1), on AR function in prostate(More)
Solid tumors have an increased reliance on Hsp70/Hsp90 molecular chaperones for proliferation, survival and maintenance of intracellular signaling systems. An underinvestigated component of the chaperone system is the tetratricopeptide repeat (TPR)-containing cochaperone, which coordinates Hsp70/Hsp90 involvement on client proteins as well as having diverse(More)
Androgen receptor (AR) signaling in stromal cells is important in prostate cancer, yet the mechanisms underpinning stromal AR contribution to disease development and progression remain unclear. Using patient-matched benign and malignant prostate samples, we show a significant association between low AR levels in cancer associated stroma and increased(More)
In breast cancer, progesterone receptor (PR) positivity or abundance is positively associated with survival and treatment response. It was initially believed that PR was a useful diagnostic marker of estrogen receptor activity, but increasingly PR has been recognised to play an important biological role in breast homeostasis, carcinogenesis and metastasis.(More)
Peroxidases are heme-containing enzymes released by activated immune cells at sites of inflammation. To-date their functional role in human health has mainly been limited to providing a mechanism for oxidative defence against invading bacteria and other pathogenic microorganisms. Our laboratory has recently identified a new functional role for peroxidase(More)
Prostate cancer has, for decades, been treated by inhibiting androgen signalling. This is effective in the majority of patients, but inevitably resistance develops and patients progress to life-threatening metastatic disease - hence the quest for new effective therapies for 'castrate-resistant' prostate cancer (CRPC). Studies into what pathways can drive(More)
BACKGROUND Improving our ability to predict cancer progression and response to conservative or radical intent therapy is critical if we are to prevent under or over treatment of individual patients. Whereas the majority of solid tumors now have a range of molecular and/or immunological markers to help define prognosis and treatment options, prostate cancer(More)
