Background: Calotropis gigantea (family: Asclepiadaceae) has been known to contain cardiac glycosides. The C. gigantea extracts have been reported as cytotoxic to a few cancer cell lines. The present study was designed to examine the effect of Calotropis gigantea methanolic extract (CGME) on the growth and apoptosis in human breast carcinoma cell line (MCF-7 cells).Methods: The study was ...

Electrophoresis of proteins, especially seed proteins, and karyological studies are useful techniques for determining species and solving the problems of modern taxonomy. The present study was carried out on two species of the Apocynaceae family, Rhazya stricta Decasine and Nerium 01eancder.L. Seed samples of these two genera were taken from the south-east of Iran and SDS-PAGE analysis of th...
