DNA tetrahedrons unlock sharper cancer targeting with vitamin E tweak

Conventional cancer treatments, such as chemotherapy, often lack specificity and can damage both cancerous and healthy cells, leading to severe side effects. With this in mind, researchers at Indian Institute of Technology Gandhinagar (IITGN) have developed DNA nanostructures called tetrahedrons and modified them by attaching a vitamin E-derived molecule called alpha-tocopherol succinate (αT), which can disrupt vital functions inside cancer cells while acting protectively in healthy cells. By incorporating αT into the DNA tetrahedrons, the researchers significantly enhanced cellular uptake and improved anticancer efficacy, resulting in more selective and effective elimination of cancer cells.
