To evaluate the anti-colitic effect of lactic acid bacteria by cDNA microarray analysis, a lactic acid bacteria mixture (LM) consisting of Lactobacillus brevis HY7401, L. suntoryeus HY7801 and Bifidobacterium longum HY8004 was orally administered to dextran sulfate (DSS)-induced colitic mice and the expression profile of numerous genes was assessed. DSS treatment caused colitic outcomes such as inflammation and colon shortening. DSS also up-regulated the expression of inflammation-related genes: pro-inflammatory and chemotactic cytokines, including IL-1beta, TNF-alpha, IL-6, CCL2, CCL4, CCL7, CCL24, CXCL1, CXCL2, CXCL5, CXCL9 and CXCL10, and their receptors CCR3 and CCR7, and other colitis-related genes such as COX-2, PAP, MMP family, S100a8, S100a9 and DEFA1. LM treatment inhibited the mRNA expression of inflammation-related and tissue remodeling genes induced by DSS as well as the colitic symptoms. LM inhibition for the DSS-induced expression of the representative inflammatory markers, IL-1beta, TNF-alpha and COX-2, was supported by quantitative real-time polymerase chain reaction analysis. These findings suggest that LM ameliorates DSS-induced colitis by regulating inflammatory-related cytokines as well as tissue remodeling genes.

Canine osteosarcoma is an aggressive primary bone tumor that shows metastasis to distal regions and is associated with a high mortality rate. However, the pathophysiological mechanisms of canine osteosarcoma are not well characterized. In addition, development of prognostic factors and novel therapeutic agents is necessary to efficiently treat osteosarcoma. Therefore, we studied the effects of myricetin, an antioxidant found in berries, nuts, teas, wine, and vegetables, on apoptosis and signal transduction in the canine osteosarcoma cell lines, D-17 and DSN. Results of the present study demonstrated that treatment with myricetin decreased cell proliferation and DNA replication, while it increased apoptotic DNA fragmentation in D-17 and DSN cells. In addition, it increased generation of ROS, lipid peroxidation, and depolarization of MMP in both D-17 and DSN cells. Myricetin treatment activated phosphorylation of AKT, p70S6K, ERK1/2, JNK, and p90RSK in canine osteosarcoma cells. Moreover, inhibition of PI3K and MAPK using LY294002, U0126, or SP600125, in addition to myricetin treatment, effectively suppressed cell proliferation compared to treatment with myricetin or each inhibitor alone. Therefore, we concluded that myricetin may be a potentially effective and less toxic therapeutic agent to prevent and control progression of canine osteosarcoma.
