- Description
This study showed that long interspersed element-1 (LINE-1) ORF2p expression is almost undetectable in human cancers. LINE-1 is the major driver of mobile DNA activity in humans. When expressed, LINE-1 loci produce bicistronic transcripts encoding two proteins essential for retrotransposition, ORF1p and ORF2p. ORF2p expression is not well characterized in human tissues and cell lines. For the study,...

- 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...
