MicroRNAs

3.0K
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...

mTOR Signaling and Cancer Progression

3.8K
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.
The mTOR pathway or the...

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Prostate cancer (PCa) is a growing health concern with increasing prevalence.
  • Current diagnostic methods like PSA testing and DRE have limitations in precision.
  • Altered microRNA (miRNA) expression is observed in PCa patients, indicating potential biomarker utility.

Purpose of the Study:

  • To review miRNA expression patterns in prostate cancer patients.
  • To explore the role of miRNAs in PCa diagnosis and prognosis.
  • To investigate the application of miRNAs in PCa treatment strategies, including integration with Traditional Chinese Medicine (TCM).

Main Methods:

  • Literature review of studies on miRNA expression in prostate cancer.
  • Analysis of research on miRNA biomarkers for PCa diagnosis and prognosis.
  • Examination of studies on miRNA-targeted therapies and their integration with TCM.

Main Results:

  • Specific miRNAs exhibit altered expression levels in PCa, suggesting diagnostic and prognostic potential.
  • miRNAs show promise in TCM for syndrome differentiation and treatment effectiveness assessment.
  • miRNA-targeted therapies are advancing, enabling personalized PCa treatment.

Conclusions:

  • miRNAs represent promising biomarkers for prostate cancer diagnosis and prognosis.
  • Integrating miRNAs with TCM offers novel therapeutic avenues for PCa.
  • Targeting miRNAs facilitates personalized and precise treatment strategies for prostate cancer.
