ABSTRACT

PREMISE OF THE STUDY: Novel and cost-effective microsatellite markers were developed to explore the population genetics, biogeographic structure, and evolutionary history of the prized Euro-Asian wild edible ectomycorrhizal fungus Tricholoma matsutake (Tricholomataceae). METHODS AND RESULTS: Eighteen new polymorphic simple sequence repeat loci, detected from a microsatellite-enriched genomic library, were used to characterize 131 individuals from eight T. matsutake populations. The number of alleles ranged from two to 10, with averages of 1.42 to 3.22. Levels of observed and expected heterozygosity ranged from 0.00-1.00 and from 0.00-0.83, with mean values of 0.21 and 0.26, respectively. In total, 50% of the loci showed interspecific transferability and polymorphism in the related species T. equestre. CONCLUSIONS: These newly developed markers will aid research into the genetic diversity and population structure of T. matsutake. They can also be used in other species of Tricholoma.

ABSTRACT

BACKGROUND/AIM: Dendritic cell-based vaccine therapy for renal cell carcinoma is effective but requires improvement. Here we explored whether combination therapy with dendritic cell-based vaccine and anti-CD69 antibody can enhance antitumor efficacy in renal cell carcinoma-bearing mice. MATERIALS AND METHODS: Balb/c mice were challenged subcutaneously with murine renal cell carcinoma (Renca) cells. On day 3 after tumor cell inoculation, tumor-bearing mice either were left untreated or were treated with Renca tumor lysate-pulsed dendritic cells (i.e. dendritic cell-based vaccine), anti-CD69 antibody, or a combination of Renca tumor lysate-pulsed dendritic cells with anti-CD69 antibody. The mice were sacrificed on day 28. Tumor volume was measured for analysis of antitumor efficacy. Spleens were excised to evaluate antitumor immunological responses by measuring the proliferation and activation of T cells, which have the capacity to recognize and destroy tumor cells. RESULTS: Combination treatment with Renca tumor lysate-pulsed dendritic cells and anti-CD69 antibody resulted in significant decreases in tumor volume and significant increases in T-cell proliferation and activity, compared with no treatment or either treatment alone. CONCLUSION: These findings indicate that anti-CD69 antibody can potentiate antitumor efficacy of dendritic cell-based vaccine. The augmented therapeutic efficacy conferred by the combination therapy may be associated with increased T-cell proliferation and activity.
