Research Abstract |
The investigation of the telomere lengths in the esophageal epithelium revealed that there is no difference among the ALDH genotype in telomere lengths, but the epithelium has short telomeres in the large iodine-unstained lesions with multiplicity. Telomere shortening may not generate cancer directly, but may create conditions under which SCC can develop more easily, depending on subsequent exposure to carcinogens.
