Targeting androgen receptor (AR) with antiandrogen Enzalutamide increases prostate cancer cell invasion yet decreases bladder cancer cell invasion via differentially altering the AR/circRNA-ARC1/miR-125b-2-3p or miR-4736/PPARγ/MMP-9 signals.

Cell Death Differ 2021 Jun 14. Epub 2021 Jun 14.

George Whipple Lab for Cancer Research, Departments of Pathology, Urology, Radiation Oncology and The Wilmot Cancer Institute, University of Rochester Medical Center, Rochester, NY, USA.

Androgen-deprivation therapy (ADT) via targeting androgens/androgen receptor (AR) signals may suppress cell proliferation in both prostate cancer (PCa) and bladder cancer (BCa), yet its impact on the cell invasion of these two urological cancers remains unclear. Here we found targeting androgens/AR with either the recently developed antiandrogen Enzalutamide (Enz) or AR-shRNAs led to increase PCa cell invasion, yet decrease BCa cell invasion. Mechanistic dissection revealed that suppressing androgens/AR signals could result in differential alterations of the selective circular RNAs (circRNAs) as a result of differential endogenous AR transcription.

Differential gene regulation in DAPT-treated Hydra reveals candidate direct notch signalling targets.

J Cell Sci 2021 Jun 14. Epub 2021 Jun 14.

Ludwig Maximilians-University Munich, Germany, Biocenter, 82152 Planegg-Martinsried, Großhaderner Str. 2, Germany.

In Hydra, Notch inhibition causes defects in head patterning and prevents differentiation of proliferating nematocyte progenitor cells into mature nematocytes. To understand the molecular mechanisms by which the Notch pathway regulates these processes we performed RNAseq and identified genes that are differentially regulated in response to 48 hours of treating the animals with the Notch-inhibitor DAPT. To identify candidate direct regulators of Notch-signalling, we profiled gene expression changes that occur during subsequent restoration of Notch-activity and performed promoter analyses to identify RBPJ transcription factor binding sites in the regulatory regions of Notch-responsive genes.
