Insights

RNA interference therapy shows promise for Ewing's sarcoma by targeting the EWS/FLI-1 fusion gene. Effective delivery systems are crucial for this novel treatment approach.

Area of Science:

  • Oncology
  • Molecular Biology
  • Gene Therapy

Background:

  • Ewing's sarcoma is characterized by a specific chromosomal translocation involving the EWS and ETS genes.
  • This unique EWS/FLI-1 fusion gene presents a viable target for therapeutic intervention.

Purpose of the Study:

  • To explore the potential of RNA interference (RNAi)-based therapies for Ewing's sarcoma.
  • To review different RNAi modalities and delivery systems for effective tumor targeting.

Main Methods:

  • Summarized RNAi mechanisms and therapeutic products (siRNA, shRNA, bi-shRNA).
  • Reviewed effective delivery systems for systemic RNAi therapy.
  • Assessed preclinical silencing strategies targeting EWS/FLI-1 sequences.

Main Results:

  • Demonstrated effectiveness of various silencing strategies against EWS/FLI-1 in preclinical models.
  • Identified promising delivery systems for RNAi-based therapeutics.

Conclusions:

  • RNAi-based therapeutics offer a testable and achievable strategy for managing Ewing's sarcoma.
  • Targeting the EWS/FLI-1 fusion gene with RNAi holds significant therapeutic potential.

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...

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...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
