Insights

Long non-coding RNAs (lncRNAs) are increasingly implicated in prostate cancer (PCa) development. Dysregulated lncRNAs offer potential as biomarkers for aggressive PCa and novel therapeutic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Prostate cancer (PCa) remains a leading cause of cancer-related deaths in men.
  • The precise etiology of PCa is not fully understood despite advances in genomic and epigenetic research.
  • Long non-coding RNAs (lncRNAs) have emerged as key regulators of gene expression, particularly through epigenetic mechanisms.

Purpose of the Study:

  • To summarize current knowledge on the roles of lncRNAs in prostate cancer.
  • To highlight the potential of lncRNAs as biomarkers for aggressive PCa.
  • To explore lncRNAs as novel therapeutic targets in PCa.

Main Methods:

  • Review of accumulated evidence on lncRNA dysregulation in PCa.
  • Analysis of functional studies implicating lncRNAs in prostate carcinogenesis.
  • Examination of lncRNA targeting of key signaling pathways and epigenetic mechanisms.

Main Results:

  • Hundreds of lncRNAs are dysregulated in prostate cancer.
  • lncRNAs contribute to PCa by targeting pathways like PTEN/AKT and androgen receptor signaling.
  • lncRNAs are involved in chromatin remodeling complexes relevant to PCa.

Conclusions:

  • lncRNAs play significant roles in the development and progression of prostate cancer.
  • Dysregulated lncRNAs show promise as diagnostic and prognostic biomarkers for aggressive PCa.
  • Targeting lncRNAs represents a potential novel therapeutic strategy for prostate cancer treatment.

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Types of RNA

Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

MicroRNAs

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...
