Story summary
- Okayama University researchers demonstrated that Archaerhodopsin 3 (AR3) can induce apoptosis in cancer cells when exposed to green light.
- They inserted AR3 genes into mouse colorectal and melanoma cancer cell lines and observed over 40% and 60% cell death, respectively, due to increased alkalinity.
- In vivo tests showed tumors expressing AR3 were 65% to 75% smaller after laser exposure.
