Upregulation of constitutively-active androgen receptor splice variants (AR-Vs) has been implicated in AR-driven tumor progression in castration-resistant prostate cancer. To date, functional studies of AR-Vs have been focused mainly on their ability to regulate gene expression independent of the full-length AR (AR-FL). Here, we showed that AR-V7 and ARv567es, two major AR-Vs, both facilitated ...
Androgen receptor (AR) signaling is essential for cancer cell proliferation throughout much, if not all, of the course of a patient’s journey through prostate cancer. Discovery of the AR in the late 1960s prompted development of antiandrogen drugs that competitively inhibit binding of androgens to the AR ligandbinding domain (LBD), leading to conformational changes in AR that disrupt its functi...
Two novel oral drugs that target androgen signaling have recently become available for the treatment of metastatic castration-resistant prostate cancer (mCRPC). Abiraterone acetate inhibits the synthesis of the natural ligands of the androgen receptor, whereas enzalutamide directly inhibits the androgen receptor by several mechanisms. Abiraterone acetate and enzalutamide appear to be equally ef...
BACKGROUND The androgen-receptor isoform encoded by splice variant 7 lacks the ligand-binding domain, which is the target of enzalutamide and abiraterone, but remains constitutively active as a transcription factor. We hypothesized that detection of androgen-receptor splice variant 7 messenger RNA (AR-V7) in circulating tumor cells from men with advanced prostate cancer would be associated with...
Introduction: Androgen deprivation therapy (ADT) with androgen receptor axis-targeted (ARAT) is the standard of care provided to patients metastatic prostate cancer. While effective, it results in sequelae, such as loss skeletal muscle mass. In this study, we compared sarcopenic effects abiraterone and enzalutamide, two ARATs used treat Methods: Our cohort comprised 55 diagnosed hormone-naive c...
Enzalutamide in chemo-naïve castration-resistant prostate cancer: effective for most but not for all
Continued research in the treatment of castration-resistant prostate cancer (CRPC) has allowed for a clearer understanding of this disease entity and further treatment advances. In a study recently published by Beer et al. in the New England Journal of Medicine, another advance to treatment was demonstrated for the androgen receptor (AR) signaling inhibitor, enzalutamide, in patients with chemo...
Active surveillance (AS) is a widely recognized and utilized option by which prostate cancer patients with less aggressive tumors on diagnosis defer immediate traditional conventional therapy (surgery, radiation) and undergo close monitoring by a physician for any clinical or pathologic changes. The juxtaposition of low- to intermediate-risk elderly patients between effective and conventional t...
Prostate cancer (PCa) is the most common malignancy among Western men and the second leading-cause of cancer related deaths. For men who develop metastatic castration resistant PCa (mCRPC), survival is limited, making the identification of novel therapies for mCRPC critical. We have found that deficient lipid oxidation via carnitine palmitoyltransferase (CPT1) results in decreased growth and in...
