WebJan 1, 1990 · Key Words: crossllnking, aging, differential scanning calorimetry INTRODUCTION ACCORDING TO the crosslinking theory, aging is caused by the progressive linking together of large vital molecules. When many such molecules in a cell get linked together into huge tangles, intracellular transport is impeded. WebDNA cross-linking can in turn lead to various effects of aging, especially cancer. [20] Other cross-linking can occur between fat and protein molecules, which leads to wrinkles.
