Approach to Design of Potent RNA Interference-Based Preparations Against Hepatocellular Carcinoma-Related Genes

Area of Science:

• Oncology
• Molecular Biology
• Bioinformatics

Background:

• Hepatocellular carcinoma (HCC) presents a significant global health challenge with high mortality rates.
• Conventional therapies for HCC often show limited efficacy due to tumor heterogeneity.
• There is a need for novel therapeutic strategies, including targeted gene silencing.

Purpose of the Study:

• To develop a computational framework for designing potent small interfering RNAs (siRNAs) against genes driving HCC.
• To investigate the efficacy of synthetic siRNAs targeting integrin beta 1 (ITGB1) and CD47 mRNA in HCC.

Main Methods:

• Utilized a software algorithm for designing unmodified and modified siRNAs targeting ITGB1 and CD47.
• Performed solid-phase synthesis of selected siRNA candidates.
• Validated siRNA efficacy through in vitro gene expression suppression assays.

Main Results:

• Successfully designed and synthesized potent siRNAs targeting ITGB1 and CD47 mRNA.
• Demonstrated significant gene expression suppression, achieving over 50-fold reduction in target mRNA levels in vitro.
• Validated the potential of RNA interference as a therapeutic strategy for HCC.

Conclusions:

• The developed siRNA design framework offers a robust method for targeting HCC-implicated genes.
• Synthetic siRNAs targeting ITGB1 and CD47 show strong potential for inhibiting HCC progression.
• This approach represents a promising advancement in the development of targeted therapies for hepatocellular carcinoma.
