We analyzed the ability of interferon (IFN)-gamma knockout mice (GKO) to reject a colon carcinoma transduced with interleukin (IL)-12 genes (C26/IL-12). Although the absence of IFN-gamma impaired the early response and reduced the time to tumor onset in GKO mice, the overall tumor take rate was similar to that of BALB/c mice. In GKO mice, C26/IL-12 tumors had a reduced number of infiltrating le...

We previously reported that oral ingestion of Lentinula edodes mycelia (L.E.M.) extract can inhibit the growth of a subcutaneously established melanoma in a T cell-dependent manner via mitigation of regulatory T cell (Treg)-mediated immunosuppression. In this study, we tested the antitumor effect and mechanism of oral ingestion of L.E.M. extract f...

The structural and electronic properties of C24-2nBn Nn and M@ C24-2nBn Nn (M= alkaline and earth alkaline metals; n=3 and 6) molecules are studied using the Density Functional Theory (DFT). It was found that the most interaction is in M@ C24-2nBn Nn complexes (M=Be, Mg; n=3 and 6). The negative nucleus-independent chemical shifts confirm that C24-2nBn Nn (n=3 and 6) cages exhibit aromatic char...

alkaline complexes by X-ray crystallography,8) Seyeral studies on the chemical modification of the monensin skeleton have been reported, either on the Ci-Cs carboxylic moiety,9・iO) or at the C,,-hydroxyl group,ii) fo11owing the isolation of antibiotics X-14667A and Bi2) (monensin C26-phenethyl urethans). We have shown that the C26-chloro-4 phenyl urethan derivative had a transport selectivity, ...

[D]-H6L9, as a pH-responsive anti-microbial peptide (AMP), has been evidenced by us to be an excellent choice in tumor microenvironment-responsive delivery as it could render liposomes responsive to the acidified tumor microenvironment. However, [D]-H6L9-modified liposomes could not actively target to tumor area. Therefore, integrin αvβ3-targeted peptide RGD was co-modified with [D]-H6L9 onto l...

We investigated the effects of combining tacrolimus and azole antifungal agents in azole-resistant strains of Candida albicans by comparing the accumulation of [3H]itraconazole. The CDR1-expressing resistant strain C26 accumulated less itraconazole than the CaMDR-expressing resistant strain C40 or the azole-sensitive strain B2630. A CDR1-expressing Saccharomyces cerevisiae mutant, DSY415, showe...

Fungal sphingolipids contain ceramide with a very-long-chain fatty acid (C26). To investigate the physiological significance of the C26-substitution on this lipid, we performed a screen for mutants that are synthetically lethal with ELO3. Elo3p is a component of the ER-associated fatty acid elongase and is required for the final elongation cycle to produce C26 from C22/C24 fatty acids. elo3delt...

We evaluated whether antibody response correlates with tumor therapy by cytokine gene-modified tumor cell vaccines. To characterize the antibody (Ab) response against a known antigen, colon carcinoma C26 cells and C26 variants engineered to produce interleukin (IL) 12 or IL-4 were further transduced to express the human tumor-associated antigen gp38 folate receptor (FR) alpha. Irradiated IL-12-...
