Ganoderic acid D can inhibit the growth of numerous cancer cell lines and it inhibits HeLa human cervical carcinoma cells with an IC 50 of 17.3 mM. Ganoderic acid D (1-50 μM; 24-72 hours) reduces the cell survival rate in a dose- and time-dependent manner. Ganoderic acid D (10, 50 μM; 24, 48 hours) induces G2/M phase arrest. Ganoderic acid D (10, 50 μM; 24, 48 hours) induces a morphological change typical of apoptosis in HeLa cells. Ganoderic acid D (10 μM; 48 hours) up-regulates 14-3-3E and PRDX3. Cell Viability Assay Cell Line: HeLa human cervical carcinoma cell line (CCL-2) Concentration: 1, 5, 10, 20, 50 μM Incubation Time: 24, 48, 72 hours Result: Reduced the cell survival rate in a dose- and time-dependent manner and had an IC 50 value of 17.3 μM for 48 hours treatment. Cell Cycle Analysis Cell Line: HeLa human cervical carcinoma cell line (CCL-2) Concentration: 10, 50 μM Incubation Time: 24, 48 hours Result: Induced G2/M phase arrest. Displayed a cell cycle profile with an elevated G2/M cell population after 24-h treatment with 10 μM. Apoptosis Analysis Cell Line: HeLa human cervical carcinoma cell line (CCL-2) Concentration: 10, 50 μM Incubation Time: 48 hours Result: Induced a morphological change typical of apoptosis in HeLa cells. Western Blot Analysis Cell Line: HeLa human cervical carcinoma cell line (CCL-2) Concentration: 10 μM Incubation Time: 48 hours Result: Up-regulated 14-3-3E and PRDX3.
