Recent advancements in biotechnology have taken a leap towards revolutionizing cancer treatment, thanks to pioneering research from the Hebrew University of Jerusalem. A team led by Dr. Raphael I. Benhamou, including researchers Elias Khaskia and Dipak Dahatonde, has developed an innovative smart drug tailored to target a unique RNA structure vital for the survival of certain cancer cells. This approach could transform cancer treatment by tackling the disease right at its molecular root.
The research zeroes in on TERRA, an RNA molecule implicated in maintaining chromosomal stability. In specific cancer cells, TERRA is hijacked to sustain their aggressive growth and division. The novel drug employs a sophisticated technology known as RIBOTAC (Ribonuclease-Targeting Chimera) to locate and dismantle TERRA within these cancer cells, all while sparing the healthy RNA.
At the core of RIBOTAC technology is a small molecule that specifically targets the G-quadruplex, a distinctive folding pattern present in TERRA RNA. This target molecule lures the cell’s own RNase L enzyme, which proceeds to degrade the TERRA RNA, effectively unraveling the cancer cells’ lifecycle. In laboratory tests with cancer cell lines such as HeLa and U2OS, this method succeeded in significantly reducing TERRA levels and slowing cancer proliferation.
This new strategy marks a pivotal shift in oncology by shifting the therapeutic focus towards RNA. Traditionally, cancer therapies have largely concentrated on proteins, but targeting RNA offers new avenues for tackling diseases that once seemed insurmountable. “Instead of only focusing on proteins, we’re now learning how to target the RNA that controls them,” Dr. Benhamou explained, emphasizing the transformative potential that lies in this research.
