In contrast, in the enhancing tumor region, the ELOVL2 expression positively correlated with the number of cigarette packs smoked per year, the ELOVL4 expression positively correlated with height, the ELOVL7 expression negatively correlated with age, and the ELOVL5 expression positively correlated with body weight and BMI. This evidence concerns the gene ELOVL2 and neoplasm.
