24 Apr 2018 --- Acyclic retinoid, an artificial compound derived from vitamin A, may prevent the reoccurrence of liver cancer tumors. The vitamin A compound targets one common class of liver cancer cells, hepatocellular carcinoma (HCC), which are indicative of a highly lethal cancer with an extremely high rate of recurrence and relapse. The study proves how the acyclic retinoid can slow the growth of the cancer: by targeting levels of the dangerous MYCN in cells, this is true even amongst highly treatment-resilient “cancer stem cells.”
