The invention relates to a nutritive composition which consists of resveratrol and yeast glucan and has the function of health protection. The nutritive composition overcomes the defects of poor treatment effect and toxic and side effects by adopting Western medicines for hyperglycemic and hypolipemic treatment in the prior art. The resveratrol is an important plant antitoxin and has the functions of antioxidation, prevention and treatment of cardiovascular diseases, prevention of cancer, antivirus and immunoloregulation; the yeast glucan has the functions of clearing intestine, regulating the blood sugar, reducing cholesterin, improving the immunity and so on; and when the two types of immunomodulator, namely the resveratrol and the yeast glucan, are combined and applied, Cdc42 expression is obviously improved, and the resveratrol and the yeast glucan have stronger synergism. For example, the resveratrol and the yeast glucan express obvious synergistic effect in monocytes and neutrophilic granulocytes, and three cytokines (IL-1, IL-6 and TNF-alpha) are obviously lifted; and the nutritive composition influences the restoring activity of spleen cells and fluorouracil-induced leucocytopenia.

The present invention relates to molecules which function as modulators (i.e., inhibitors and agonists) of the Ras-homologous (Rho) family of small GTPases (e.g. Rac, Cdc42 and Rho GTPases) and their use to treat diseases, including cancers (including solid tumors-medulloblastoma, ovarian, breast, head and neck, testicular, prostate among others and hematologic malignancies-B cell lymphoma, where these GTPases are overexpressed or hyperactivated), sporadic and genetic diseases where activation of Rho GTPases plays a pivotal role (Menkes disease, rheumatoid arthritis, atherosclerosis, diabetes (type 1), Huntington's disease and Alzheimer's disease) which are mediated through these proteins. Compounds according to the present invention may also be used as a therapy for the treatment of Entamoeba spp. or Acanthamoeba spp, infections, especially including Entamoeba histolytica.

The present invention relates to compositions and methods useful in studying or modulating melanin pigmentation in the skin. Particularly, the invention relates to compositions comprising a substance capable of modulating the activity or expression of ALK6 (SEQ ID 2) or Cdc42 which in turn are capable of modulation of the transfer of melanin from melanocytes to keratinocytes and potentially from keratinocytes to keratinocytes. The invention also relates to assays for identifying such compositions, and methods of modulating skin pigmentation.

The present invention relates to improvement of epithelial or endothelial barrier function by increasing a level of myotonic dystrophy kinase-related Cdc42-binding kinases a (MRCKalpha) in one or more cells in the barrier.

The invention relates to a method for the treatment of cancer by changing the intracellular activity of cdc42. The activity can be increased by treatment with small molecules, for instance, treatment with non-hydrolyzable GTP-analogues of cdc-42. Also, the activity can be increased by inhibiting nm23-H1 and / or nm23-H2, which are factors having an inhibitory effect on the expression and / or activity of cdc-42. It is also shown that a decrease in the intracellular activity of cdc-42 has a beneficial effect. Further embodiments of the invention are the compounds for use in such methods, pharmaceutical preparations comprising such compounds and use of such compounds for the preparation of a medicament for treatment of cancer.
