  • Studies by Kwang Hyun Cha et al., Natural Products Research Center, Korea, has found that semipurified extracts of C. ellipsoideaand C. vulgaris inhibited HCT116 cell growth in a dose-dependent manner, yielding IC50values of 40.73 ± 3.71 and 40.31 ± 4.43 μg/mL, respectively. In addition, treatment with both chlorella extracts enhanced the fluorescence intensity of the early apoptotic cell population in HCT116 cells. C. ellipsoidea extract produced an apoptosis-inducing effect almost 2.5 times stronger than that of the C. vulgaris extract. These results indicate that bioactive xanthophylls of C. ellipsoidea might be useful functional ingredients in the prevention of human cancers. (More)
  • Research by Kuniaki Tanaka et al., Research Laboratories, Chlorella Industries co.Ltd., Japan, have found that a glycoprotein extract (CVS), derived from the unicellular green alga Chlorella vulgaris, strain CK22, exhibited a pronounced antitumor effect against both spontaneous and experimentally induced metastasis. Inhibition of tumor metastasis was enhanced when intratumor administration of CVS was followed by s.c. injection of CVS. The antitumor activity of CVS was reflected in antigen-specific, T-cell-mediated immunity. Both CD4 and CD8 T cells contributed to the antimetastatic effects, as shown by in vivo depletion experiments with anti-T-cell subset antibodies. (More)
  • Research by Yasmin Anum Mohd Yusof et al., Department of Biochemistry, Malaysia, have found that Chlorella vulgaris decreased the number of viable HepG2 cells in a dose dependent manner when HepG2 liver cancer cells and WRL68 normal liver cells were treated with various concentrations (0-4 mg/ml) of hot water extract of C. vulgaris after 24 hours incubation. Thus Chlorella may have anti-cancer effects. (More)
  • Jing-Gung Chung et al., Department of Biological Science and Technology, Taiwan, ROC, conducted an experiment where The effects of 80% ethanolic extract derived from commercial granule chlorella (GPE) on cell viability, invasion capacity and apoptosis in human hepatoma cell line (Hep G2 cells) were investigated. The results demonstrated that GPE decreased cell viability, induced apoptosis and showed invasion inhibitory effects in the Hep G2 cells. (More)
  • Studies by Suhaniza Sulaiman et al., Department of Biochemistry, Malaysia, have shown that liver cancer induced rats when treated with Chlorella vulgaris for 8 to 12 weeks, they showed increased levels of super oxide dismutase (SOD), glutathi0ne peroxidase (GPx) and malondialdehyde  (MDA). Thus Chlorella vulgaris may have a protective role in liver cancer induced rats by compensating the activities of antioxidant enzymes and by reducing lipid peroxidation. (More)
  • In a study by LI YAN-JUN et al., Department of Biochemistry and Molecular Biology, China, a gene of Chlorella vulgaris CvFad3 was made to express in a eukaryotic expression vector to form a recombinant and it was transfected into breast cancer cell MCF-7.
