Inhibition Mechanism of Rohdea Rothon hypha formation by Candida albicans
Objective To investigate the inhibition mechanism of rohdea roth on hyphae formation by Candida albicans.Methods MTT assay was used to detect the minimum inhibitory concentration(MIC)and minimum fungicidal concentration(MFC)of C.albicans.The inhibitory effect of fungicidal adherence was detected by MTT assay.Inverted fluorescence microscope was used to observe effect on hyphae formation.The influence on Efg1 and Hwp1gene expression were detected by RT-PCR method.Results MIC and MFC of C.albicans were 16 mg/mL and 32 mg/mL, respectively.The inhibitory effects of rohdea roth on C.albicans adherence and hyphae formation were significantly inhibited,and the concentration was dose-dependent.After the concentration of 16 mg/mL acted on C.albicans for 6 h, hyphae disappeared completely.The results of RT-PCR showed that the gene expression of Efg1 and Hwp1 could be inhibited by rohdea roth.Compared with the control group,the expression of Efg1 and Hwp1in the experimental groupwere reduced by 84.18% and 59.57%(P<0.01).Conclusion The inhibitory effect of rohdea roth on the adherence and hyphae formation of C.albicans is mainly through inhibiting the expression of Efg1 and Hwp1genes.
