Abstract:
Bcl-2, an antiapoptotic protein, is considered as a potential target in cancer treatment since its oncogenic potential has been proven and is well documented. Antisense technology and RNA interference (RNAi) have been used to reduce the expression of the Bcl-2 gene in many types of cancer cells and are effective as adjuvant therapy along with the chemotherapeutic agents. The lack of appropriate delivery systems is considered to be the main hurdle associated with the RNAi. In this review, we discuss the antiapoptotic Bcl-2 protein, its oncogenic potential, and various approaches utilized to target Bcl-2 including suitable delivery systems employed for successful delivery of siRNA.
Insights
Bcl-2 protein is a cancer target. RNA interference (RNAi) can reduce Bcl-2 expression, but effective delivery systems are needed for this cancer therapy approach.
Area of Science:
- Oncology
- Molecular Biology
- Biotechnology
Background:
- Bcl-2 is an antiapoptotic protein with proven oncogenic potential, making it a significant target in cancer therapy.
- Antisense technology and RNA interference (RNAi) are established methods for downregulating Bcl-2 gene expression.
- These RNA-based strategies have shown efficacy as adjuvant therapies alongside traditional chemotherapeutic agents.
Purpose of the Study:
- To review the role of the antiapoptotic Bcl-2 protein in oncogenesis.
- To discuss various therapeutic strategies targeting Bcl-2.
- To highlight the challenges and advancements in delivery systems for RNAi-based cancer therapies.
Main Methods:
- Literature review of studies on Bcl-2 function, oncogenic potential, and therapeutic targeting.
- Analysis of different approaches for modulating Bcl-2 expression, including antisense technology and RNA interference (RNAi).
- Examination of various delivery systems designed for small interfering RNA (siRNA) in cancer treatment.
Main Results:
- Bcl-2 overexpression contributes to cancer cell survival and resistance to apoptosis.
- RNAi offers a promising strategy to inhibit Bcl-2, potentially sensitizing cancer cells to treatment.
- The efficacy of RNAi is significantly limited by the lack of efficient and specific delivery systems for siRNA.
Conclusions:
- Targeting Bcl-2 is a viable strategy for cancer treatment.
- RNA interference presents a powerful tool for Bcl-2 gene silencing.
- Development of effective siRNA delivery systems is crucial for advancing RNAi-based cancer therapies.
