Androgen Receptor-Induced Integrin α6β1 and Bnip3 Promote Survival and Resistance to PI3K Inhibitors in Castration-Resistant Prostate Cancer

Integrins α6β1 and Bnip3 were found to promote survival of castration-resistant prostate cancer cells selectively on laminin through the induction of autophagy and mitophagy.

The MD Anderson Prostate Cancer Patient-Derived Xenograft Series (MDA PCa PDX) Captures the Molecular Landscape of Prostate Cancer and Facilitates Marker-Driven Therapy Development

Scientists studied two cell line-derived xenografts and the first 80 patient-derived xenografts (PDXs) derived from 47 human prostate cancer donors. Of these, 47 PDXs derived from 22 donors were working models and could be expanded either as cell lines or PDXs.

Biological Effect Evaluation of Glutathione-Responsive Cyclodextrin-Based Nanosponges: 2D and 3D Studies

The effect of glutathione-responsive β-cyclodextrin-based nanosponges (GSH-NS) on cell growth was evaluated on multicellular spheroids and a comparison of the GSH-NS cell growth inhibitory activity was performed between 2D and 3D cell cultures.

Targeting the ERG Oncogene with Splice-Switching Oligonucleotides as a Novel Therapeutic Strategy in Prostate Cancer

In VCaP prostate cancer cells, both splice-switching oligonucleotides were effective at inducing exon 4 skipping, which resulted in a reduction of overall ERG protein levels up to 96 hours following a single transfection.

NIH’s New Sexual-Harassment Rules Are Still Too Weak, Say Critics

On 24 June, the US National Institutes of Health (NIH) described the actions it will take when alerted to reports of unsafe behavior, including restricting scientists from peer-review panels, holding back pending grants and refusing university requests to transfer funding to other institutions in cases where a harasser changes jobs.
