Insights

Circular RNAs (circRNAs) show potential as therapeutic targets for glioblastoma multiforme (GBM), a deadly brain cancer. This study explores how circRNAs influence GBM development and resistance to therapy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Glioblastoma multiforme (GBM) is an aggressive, often incurable brain cancer with poor patient survival rates.
  • Therapeutic resistance in GBM stems from cellular heterogeneity and genetic alterations affecting critical cellular processes.
  • Novel therapeutic strategies, including combination therapies, are urgently needed to combat GBM.

Purpose of the Study:

  • To investigate the molecular and cellular mechanisms of circular RNAs (circRNAs) in glioblastoma pathogenesis.
  • To understand the role of circRNAs in regulating GBM development, proliferation, apoptosis, invasion, and chemoresistance.
  • To explore circRNAs as potential therapeutic targets for GBM treatment.

Main Methods:

  • Review and analysis of current literature on circRNAs and GBM.
  • Discussion of signaling pathways (PI3K/Akt/mTOR, Wnt/β-catenin, MAPK) involved in circRNA-mediated GBM pathophysiology.
  • Examination of circRNAs' roles in angiogenesis and metastasis in GBM.

Main Results:

  • Circular RNAs (circRNAs) can act as either tumor suppressors or oncogenes in glioblastoma.
  • circRNAs are implicated in regulating key cancer processes including cell proliferation, apoptosis, invasion, and chemoresistance.
  • Specific signaling pathways and metastatic processes are influenced by circRNAs in GBM.

Conclusions:

  • circRNAs represent promising therapeutic targets for overcoming glioblastoma resistance.
  • Understanding circRNA mechanisms provides insights into GBM pathophysiology.
  • Targeting circRNAs may offer novel strategies for improving GBM patient outcomes.

Experimental RNAi02:15

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

MicroRNAs01:22

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...

RNA Interference01:23

RNA Interference

RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

Regulated mRNA Transport02:22

Regulated mRNA Transport

In eukaryotes, transcription and translation are compartmentalized; an mRNA is first synthesized in the nucleus and then selectively transported to the cytoplasm for protein synthesis. Before transport, a pre-mRNA undergoes several steps of post-transcriptional modifications including splicing, 5' capping, and the addition of a poly-adenine tail. Various proteins bind to the pre-mRNA during these modifications. The mRNA transport takes place with the help of multiple proteins playing...

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:
