Summary
Neuroendocrine prostate cancer (NEPC) arises from prostate cancer (PCa) under therapy. MicroRNAs (miRNAs) are key epigenetic regulators driving NEPC development, offering potential diagnostic and therapeutic targets.
Area of Science:
- Oncology
- Molecular Biology
- Epigenetics
Background:
- Therapy-induced neuroendocrine prostate cancer (t-NEPC) is an aggressive variant of prostate cancer (PCa) emerging under androgen receptor (AR)-targeted therapies.
- NEPC is characterized by lineage switching to neuroendocrine differentiation (NED), exhibiting neuronal markers and poor survival rates.
- The molecular mechanisms of NED and NEPC development are complex, hindering effective diagnosis and treatment.
Purpose of the Study:
- To review the role of microRNAs (miRNAs) in the development of neuroendocrine prostate cancer (NEPC).
- To highlight miRNAs as crucial epigenetic regulators in NEPC.
- To explore the potential of miRNAs as diagnostic biomarkers and therapeutic targets for NEPC.
Main Methods:
- Literature review focusing on studies investigating miRNAs in NEPC.
- Analysis of genetic alterations associated with NEPC, including RB1, TP53, AURKA, NMYC, and EZH2.
- Examination of cellular processes like epithelial-mesenchymal transition (EMT) and cancer stemness in NED.
Main Results:
- MicroRNAs (miRNAs) play diverse roles as oncogenes and tumor suppressors in driving NEPC.
- miRNAs are involved in intercellular communication via extracellular vesicles, contributing to lineage switching.
- Studies indicate miRNAs are critical epigenetic players in therapy-induced NEPC.
Conclusions:
- MicroRNAs are central to the development of neuroendocrine prostate cancer (NEPC).
- miRNAs influence key cellular processes like EMT and stemness, driving neuroendocrine differentiation (NED).
- miRNAs show significant promise as novel diagnostic biomarkers and therapeutic targets for NEPC.

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

3.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
