- Description
Previous study showed that PIM1 phosphorylates the androgen receptor (AR), the primary therapeutic target in prostate cancer. This study examined the mechanism how PIM1 phosphorylation of AR alters its transcriptional activity. They identified the AR co-activator, 14-3-3 ζ, as an endogenous PIM1 substrate in LNCaP cells. Rapid immunoprecipitation and mass spectrometry of endogenous proteins on chromatin...

- Description
This study performed a chemical genetic screen to identify PIM1 substrates in prostate cancer cells. They identified 25 previously unknown PIM1 substrates and their phosphorylation sites. Among the identified PIM1 substrates, N-Myc Downstream-Regulated Gene 1 (NDRG1) was shown to be as an inhibitor of metastasis. The study demonstrated that PIM1 phosphorylation of NDRG1 reduced its stability, nuclear...

MPC309 Modulates Androgen Receptor Transcriptional Activity to Inhibit Therapy-Resistant Prostate Cancer
- Authors
- Justine HabaultJeffrey A. SchneiderSusan HaRachel Ruoff14 more author(s)...
- Description
Prostate cancer cells depend on the androgen receptor (AR) for survival and proliferation. This study examined the antitumor effects of compound MPC309, a trivalent display of ethisterone conjugated to a peptoid oligomer backbone that binds to the AR with nanomolar affinity. First, a structure-activity relationship study was performed to improve multivalent peptoid conjugate potency. Then, the impact...
