Cancer Gene Therapy Breakthrough: Nanoliposomes Show Potential in Treating Bladder Cancer

Strategic Insights

— 2 min read

Researchers from Baqiyatallah University of Medical Sciences in Tehran, Iran, have made a significant breakthrough in cancer gene therapy, demonstrating the potential of nanoliposomes in treating bladder cancer. A study published in Biochemistry and Biophysics Reports has shown that the inhibition of miR-21 and miR-373, two microRNAs involved in cancer development, can lead to significant changes in gene expression profiles in bladder cancer cells.

In the study, researchers encapsulated antisense oligonucleotides (ASOs) targeting miR-21 and miR-373 in liposomes and exposed bladder cancer cells (HTB-9) to the nanoliposomes. The results showed a significant reduction in miR-21 and miR-373 expression in cells exposed to the nanoliposomes, as well as a decrease in the expression of eight additional genes involved in cancer development. The study concluded that the inhibition of miR-21 and miR-373 can impact the expression profile of a gene network in bladder cancer, highlighting the potential of antimir technology as a strategy to regulate gene expression in cancer cells.
