Sources: 2. Developments: 2. Researchers are developing new experimental methods to increase the precision of cancer therapies and reduce systemic toxicity. In Japan, scientists from RIKEN and the Institute of Science Tokyo have demonstrated a proof of concept for synthesizing anti-cancer compounds directly within tumor cells. This method utilizes carbon monoxide, which is found at higher levels in certain cancer cells, as a substrate to trigger a reaction involving a palladium metal catalyst and albumin. Laboratory tests on various human cancer cell lines showed the production of phenanthridinone derivatives and the inhibition of cancer cell growth, though researchers noted the technology requires further testing to improve selectivity and safety. In the United States, a separate approach led by Dr. David Rusling involves using synthetic DNA molecules, specifically triplex-forming oligonucleotides and a synthetic DNA base known as Z, to target cancer-linked genes. This technique aims to bind to specific, difficult-to-reach GC-rich regions of the genome to control gene activity. ## Timeline ### 2026-11-04: Researchers develop new methods for targeted cancer gene and cell treatment New research highlights two innovative cancer treatment strategies: using synthetic DNA to target specific genes and utilizing carbon monoxide produced by tumors to trigger internal drug production. 2 sources. https://clstr.news/cluster/researchers-develop-new-methods-for-targeted-cancer-gene-and-cell-treatment ### 2026-10-25: Japanese researchers develop method to produce anti-cancer compounds inside tumor cells Japanese scientists have developed a way to use carbon monoxide within cancer cells to trigger the internal production of anti-cancer compounds, showing promise in laboratory tests. 2 sources. https://clstr.news/cluster/japanese-researchers-develop-method-to-produce-anti-cancer-compounds-inside-tumor-cells --- Cite as: Advancements in targeted cancer treatment research.
