miR-100-5p inhibition induces apoptosis in dormant prostate cancer cells and prevents the emergence of castration-resistant prostate cancer.

Carcinoma of the prostate is the most common cancer in men. Treatment of aggressive prostate cancer involves a regiment of radical prostectomy, radiation therapy, chemotherapy and hormonal therapy. Despite significant improvements in the last decade, the treatment of prostate cancer remains unsatisfactory, because a significant fraction of prostate cancers develop resistance to multiple treatments and become incurable.

The role of epigenetics and long noncoding RNA MIAT in neuroendocrine prostate cancer.

Neuroendocrine prostate cancer (NEPC) is the most lethal prostatic neoplasm. NEPC is thought to originate from the transdifferentiation of AR-positive adenocarcinoma cells. We have previously shown that an epigenetic/noncoding interactome (ENI) orchestrates cancer cells' plasticity, thereby allowing the emergence of metastatic, drug-resistant neoplasms.

The epigenetic/noncoding origin of tumor dormancy.

Cancer stem cells (CSCs) have been implicated as the seeds of treatment resistance and metastasis, which are the most deadly features of a neoplasm. However, an unequivocal definition of the CSC phenotype is still missing. A common feature of normal and aberrant stem cells is their ability to enter a prolonged dormant state.

The long non-coding RNA PCGEM1 is regulated by androgen receptor activity in vivo.

Background: Long non-coding RNAs (lncRNAs) can orchestrate oncogenic or tumor-suppressive functions in cancer biology. Accordingly, PCGEM1 and PRNCR1 were implicated in progression of prostate cancer (PCa) as transcriptional co-regulators of the androgen receptor (AR). However, these findings were recently refuted asserting that neither gene physically binds to the AR.
