During its intensive division, a tumor cell synthesizes its components, including fatty acids, hence the increased expression of SCD in tumors, e.g., observed in human hepatocellular carcinoma [83], anaplastic thyroid carcinoma [84], breast cancers [85], prostate cancers [85], or lung adenocarcinoma [86]. This evidence concerns the gene SCD and thyroid gland undifferentiated (anaplastic) carcinoma.
