In contrast, those genes that were actually upregulated or increased by way of a lack of sleep, were genes associated with the promotion of tumors, genes associated with long-term chronic inflammation within the body, and genes associated with stress, and, as a consequence, cardiovascular disease.
În contrast, acele gene care au fost activate sau le-a crescut activitatea din cauza lipsei de somn, au fost genele asociate  cu dezvoltarea de tumori, genele asociate cu inflamaţia cronică şi genele asociate cu stresul şi drept consecinţă,  cu bolile cardiovasculare.
