Abstract |
Apoptosis-inducing activity of synthetic CDCA derivatives, HS-1199 and HS-1200, on gastric cancer cell line SNU-1 cells was explored. CDCA derivatives demonstrated various apoptosis hallmarks, such as mitochondrial changes, activation of caspase, DNA fragmentation, and nuclear condensation. Importantly, the orphan receptor Nur77 (TR3) was shown to translocate from the nucleus to mitochondria at the early time points after CDCA derivatives treatment. These data support the theory that CDCA derivatives-induced apoptosis of SNU-1 gastric cancer cell lines is mediated by mitochondria and caspase, and, at least in part, by Nur77.
