MicroRNAs

23.5K
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 Retinoblastoma Gene

4.5K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Glioblastoma treatment requires novel therapeutic targets for precision medicine.
  • MicroRNA-144-5p (miR-144-5p) demonstrates anti-tumor effects in various cancers.
  • Ginsenoside Rd is a compound with potential therapeutic applications.

Purpose of the Study:

  • To investigate the anti-tumor effects of ginsenoside Rd on glioblastoma.
  • To elucidate the molecular mechanism involving miR-144-5p and Toll-like receptor 2 (TLR2) in glioblastoma.
  • To identify potential new therapeutic targets for glioblastoma.

Main Methods:

  • Cell proliferation and migration assays were performed on glioblastoma cells treated with ginsenoside Rd.
  • Expression levels of miR-144-5p and Toll-like receptor 2 (TLR2) were analyzed.
  • miR-144-5p inhibition was used to assess its role in ginsenoside Rd's effects.

Main Results:

  • Ginsenoside Rd significantly reduced glioblastoma cell proliferation and migration.
  • Ginsenoside Rd treatment led to increased miR-144-5p levels and decreased TLR2 expression.
  • Inhibition of miR-144-5p partially reversed the anti-proliferative and TLR2-downregulating effects of ginsenoside Rd.

Conclusions:

  • Ginsenoside Rd exerts anti-tumor effects in glioblastoma through the miR-144-5p/TLR2 regulatory axis.
  • The identified ginsenoside Rd/miR-144-5p/TLR2 pathway represents a novel target for glioblastoma diagnosis and therapy.
  • This study provides a basis for developing precision medicine strategies against glioblastoma.
