Title E-cigs and cancer: Early warning in oral cells
Description E-cigs and cancer: Early warning in oral cells Besaratinia emphasized that the molecular changes seen in the study aren’t cancer, or even pre-cancer, but rather an early warning of a process that could potentially lead to cancer if unchecked. The researchers looked at gene expression in oral cells collected from 42 e-cigarette users, 24 cigarette smokers and 27 people who didn’t smoke or Vape Wholesale. Gene expression is the process by which instructions in our DNA are converted into a functional product, such as a protein. Certain alterations in gene expression can lead to cancer. They focused on oral epithelial cells, which line the mouth. More than 90 percent of smoking-related cancers originate in epithelial tissue, and oral cancer is associated with tobacco use. Both smokers and vapers showed abnormal expression, or deregulation, in a large number of genes linked to cancer development. Twenty-six percent of the deregulated genes in e-cig users were identical to those found in smokers. Some deregulated genes found in e-cig users, but not in smokers, are nevertheless implicated in lung cancer, esophageal cancer, bladder cancer, ovarian cancer and leukemia. Besaratinia and his team plan to replicate his findings in a larger group of subjects and explore the mechanisms that cause gene deregulation. He’s also launching another experiment in which smokers switch to e-cigs; he wants to see whether any changes in gene regulation occur after the switch. “For the most part, the participants are as curious as we are to know whether these products are safe,” he said. In addition to Besaratinia, the study’s other authors are first author Stella Tommasi, Andrew Caliri, Amanda Caceres, Debra Moreno, Meng Li, Yibu Chen and Kimberly Siegmund, all of USC.u2022eney7485yyWEEEEDD
