- Abstract
- Apoptosis, a form of programmed cell death, is a critical defence mechanism against the formation and progression of
cancer and acts by eliminating potentially deleterious cells without causing such adverse effects, as inflammatory response
and ensuing scar formation. Therefore, targeting apoptotic pathways becomes an intriguing strategy for the development
of chemotherapeutic agents. In last decades, marine natural products, such as sesterterpenoids, have played an important
role in the discovery and development of new drugs. Interestingly, many of these compounds have a strong potential as
anticancer drugs by inhibiting cell proliferation and/or inducing cell death. In the present study, we investigated the effects
of scalaradial and cacospongionolide, two sesterterpenoids from Cacospongia scalaris and Fasciospongia cavernosa marine
sponges, on the apoptotic signalling pathway in three different human tumoral cells. Results were obtained by using DNA
fragmentation, comet and viability assays, quantification of the mitochondrial transmembrane potential and Western blot.
The T47D (human breast carcinoma), A431 (human epidermoid carcinoma), HeLa (human cervix carcinoma) and HCT116
(human colon carcinoma) cells were incubated for 24 h with scalaradial or cacospongionolide. Treatment of T47D cells with
scalaradial or cacospongionolide for 24 h brought about a significant increase in DNA migration as well as fragmentation.
Moreover, incubation of HCT116 and HeLa cells with scalaradial or cacospongionolide for 24 h caused an increased
expression of pro-apoptotic proteins. Furthermore, scalaradial or cacospongionolide, added to HCT116 and HeLa cells
overnight, induced a significant and concentration-dependent loss of mitochondrial transmembrane potential, an early
apoptosis signalling event. These effects paralleled with those achieved with p50 and p65, NF-kB subunits, nuclear level. In
conclusion, scalaradial and cacospongionolide, by determining human cancer cell apoptosis, may represent new promising
compounds to inhibit cancer cell proliferation. (literal)
