Are immune responses pivotal to cancer patient's long term survival? Two clinical case-study reports on the effects of Morinda citrifolia (Noni).
Dr. Desmond K.W. Wong
There are abundant claims of benefit from cancer patients' use of noni but no well-documented clinical reports in peer reviewed journals. The author examined 2 such claims through interview, and review of medical records and pathology slides. The author concludes that these cases are valuable experiences and hope to stimulate interest in noni research as an important part of adjuvant immunotherapy for cancer.

Effect of juice from Morinda citrifolia (noni) on gastric emptying in male rats.
Pu, H.F., et al
Male rats were given noni by gavage at levels of 0.25, 1, or 4 mL/kg once per day for 1 or 7 days," explained H.F. Pu and coauthors at National Yang-Ming University in Taipei. The rats in the control group were given water, while the rats in the experimental group were fasted overnight before measurement of gastrointestinal motility. The results suggest that oral noni inhibits gastric emptying in male rats via a mechanism involving stimulation of CCK secretion and CCK1 receptor activation.

Regulation of anthraquinone biosynthesis in cell cultures of Morinda citrifolia
Stalman M.; Koskamp A-M.; Luderer R.; Vernooy J.H.J.; Wind J.C.; Wullems G.J.; Croes A.F.
Cell cultures of Morinda citrifolia L. are capable of accumulating substantial amounts of anthraquinones. Chorismate formed by the shikimate pathway is an important precursor of these secondary metabolites. Isochorismate synthase (EC 5.4.99.6), the enzyme that channels chorismate into the direction of the anthraquinones, is involved in the regulation of anthraquinone biosynthesis. Other enzymes of the shikimate pathway such as deoxy-D-arabino-heptulosonate 7-phosphate synthase (EC 4.1.2.15) and chorismate mutase (EC 5.4.99.5) do not play a regulatory role in the process. The accumulation of anthraquinones is correlated with isochorismate synthase activity under a variety of conditions, which indicates that under most circumstances the concentration of the branchpoint metabolite chorismate is not a rate-limiting factor. Anthraquinone biosynthesis in Morinda is strongly inhibited by 2,4-D, but much less by NAA. Both auxins inhibit the activity of isochorismate synthase proportionally to the concomitant reduction in the amount of anthraquinone accumulated. However, the correlation between enzyme activity and rate of biosynthesis is less clear when the activity of the enzyme is very high. In this case, a limiting concentration of precursor may determine the extent of anthraquinone accumulation. Partial inhibition of chorismate biosynthesis by glyphosate leads to less anthraquinone accumulation, but also to a reduction in ICS activity. The complexity of the interference of glyphosate with anthraquinone biosynthesis is illustrated by the effect of the inhibitor in cell cultures of the related species Rubia tinctorum L. In these cells, glyphosate leads to an increase in anthraquinone content and a concomitant rise in ICS activity. All data indicate that the main point of regulation in anthraquinone biosynthesis is located at the entrance of the specific secondary route.

Inhibition of angiogenic initiation and disruption of newly established human vascular networks by juice from Morinda citrifolia (noni)
Conrad A. Hornick, Amy Myers, Halina Sadowska-Krowicka, Catherine T. Anthony, Eugene A. Woltering, Halina Sadowska-Krowicka
We tested the effects of noni juice in a three-dimensional fibrin clot matrix model using human placental vein and human breast tumor explants as sources for angiogenic vessel development. Noni in concentrations of 5% (vol/vol) or greater was highly effective in inhibiting the initiation of new vessel sprouts from placental vein explants, compared with initiation in control explants in media supplemented with an equivalent amount of saline. These concentrations of noni were also effective in reducing the growth rate and proliferation of newly developing capillary sprouts. When used at a concentration of 10% in growth media, noni was able to induce vessel degeneration and apoptosis in wells with established capillary networks within a few days of its application. We also found that 10% noni juice in media was an effective inhibitor of capillary initiation in explants from human breast tumors. In tumor explants which did show capillary sprouting, the vessels rapidly degenerated (2-3 days) in those exposed to media supplemented with 10% noni.

Antioxidative activity of extracts from Mengkudu (Morinda citrifolia L.) root, fruit and leaf.
ZIN, Z. M., ABDUL-HAMID, A., OSMAN, A.
This study was conducted to evaluate the antioxidative activity of extracts from different parts of Mengkudu (Morinda citrifolia L.), including leaf, fruit and root. Methanol and ethyl acetate were used as solvents and antioxidative effects measured by a ferric thiocyanate method (FTC) and thiobarbituric acid test (TBA). Roots showed the highest activity of the parts tested. The results suggest that several compounds contribute to antioxidative activity of different parts of Mengkudu. Activity in the roots may be due to both polar and non-polar compounds but, in the leaf and fruit, only to non-polar compounds.

An Immunomodulatory Polysaccharide-Rich Substance from the Fruit Juice of Morinda citrifolia (Noni) with Antitumour Activity
ANNE HIRAZUMI AND EIICHI FURUSAWA
The fruit juice of Morinda citrifolia (noni) contains a polysaccharide-rich substance (noni-ppt) with anti-tumor activity. Therapeutic administration of noni-ppt significantly increased survival time of tumor bearing mice. Results also suggested the possibility that noni-ppt may suppress tumor growth through activation of the host immune system. Noni-ppt was also capable of stimulating the release of several cytokines from immune cells. Improved survival time and curative effects occurred when noni-ppt was combined with sub-optimal doses of standard chemotherapeutic agents, suggesting important clinical applications of noni-ppt as a supplemental agent in cancer treatment.

Antitumor Studies of a Traditional Hawaiian Medicinal Plant, Morinda citrifolia (Noni), In Vitro and In Vivo.
HIRAZUMI, ANNE, Y.
The fruit juice of Morinda citrifolia L. (Noni) contains a polysaccharide-rich precipitate (noni-ppt) with antitumor activity in the Lewis Lung (LLC) peritoneal carcinomatosis model. Noni-ppt was capable of stimulating the release of several mediators from murine effector cells. The pattern of release of these mediators suggested that noni-ppt may promote both a non-specific and Th1 cell mediated antitumor response. Therapeutic administration of noni-ppt demonstrated significant suppression of S.180 ascites growth in allogenic animals, without being substantially cytotoxic to these cells in vitro. Improved survival time and curative effects occurred when noni-ppt was combined with sub-optimal doses of the standard chemotherapeutic agents.

Morinda citrifolia (noni) juice was shown to have antitumor activity on Lewis Lung carcinoma in mice. The ethanol precipitate (noni-ppt) was not directly toxic to cancer cells. Instead, it acts indirectly by enhancing the host immune system involving macrophages or lymphocytes. Noni-ppt had a beneficial effect when combined with sub-optimal doses of chemotherapeutic agents. This suggests a possibility of clinical application of noni-ppt in cancer treatment.
