Reduced NCOR2 expression accelerates androgen deprivation therapy failure in prostate cancer

Gerard Llimos Aubach

This study addresses the roles of nuclear receptor corepressor 2 (NCOR2) in prostate cancer (PC) progression in response to androgen deprivation therapy (ADT). Reduced NCOR2 expression significantly associates with shorter disease-free survival in patients ...

Separable Effects for Causal Inference in the Presence of Competing Events

Mats Julius Stensrud

In time-to-event settings, the presence of competing events complicates the definition of causal effects. Here we propose the new separable effects to study the causal effect of a treatment on an event of interest. The separable direct effect is the treatm ...

The miR-96 and RAR gamma signaling axis governs androgen signaling and prostate cancer progression

Gerard Llimos Aubach

Expression levels of retinoic acid receptor gamma (NR1B3/RARG, encodes RAR gamma) are commonly reduced in prostate cancer (PCa). Therefore, we sought to establish the cellular and gene regulatory consequences of reduced RAR gamma expression, and determine ...

An extended regulatory landscape drives Tbx18 activity in a variety of prostate-associated cell lineages

Christopher Chase Bolt, Soumya Negi

The evolutionarily conserved transcription factor, Tbx18, is expressed in a dynamic pattern throughout embryonic and early postnatal life and plays crucial roles in the development of multiple organ systems. Previous studies have indicated that this dynami ...

Characterization of cancer stem cell subpopulations from patient-derived xenografts of advanced prostate cancer

Markus Germann, Marina Bice Manuela Menna

Androgen-deprivation therapy is the standard treatment for prostate cancer. Despite the initial response, a fraction of cases manifest progression to castration-resistant prostate cancer. PCa recurrence is possibly due to androgen-independent cancer stem c ...
