白色念珠菌芽管的延伸形成细长的菌丝是破坏宿主细胞的必要条件。梭白念珠菌特异性基因EED1在这种延伸和维持丝状生长中起着至关重要的作用。在塑料表面上生长期间,eed1Δ细胞未能将芽管延伸成长丝状,并且在孵育3小时后切换回酵母生长。EED1的表达受转录因子Efg1的调控,EED1的异位过表达可恢复Efg1Δ的表达。eed 1 Δ在口腔组织感染过程中的转录谱显示菌丝相关基因的下调,包括编码另一个关键转录因子的UME 6。EED1或UME6的异位过表达挽救了eed1Δ的表达和损伤潜力。在UME6过表达过程中的转录谱确定了由Eed1或Ume6调控的基因子集。这些数据表明,Eed 1和Ume 6在调节菌丝生长的维持的途径中起作用,从而抑制菌丝到酵母的转变并允许C.上皮组织内的白色念珠菌。
The extension of germ tubes into elongated hyphae by Candida albicans is essential for damage of host cells. The C. albicans-specific gene EED1 plays a crucial role in this extension and maintenance of filamentous growth. eed1Δ cells failed to extend germ tubes into long filaments and switched back to yeast growth after 3 h of incubation during growth on plastic surfaces. Expression of EED1 is regulated by the transcription factor Efg1 and ectopic overexpression of EED1 restored filamentation in efg1Δ. Transcriptional profiling of eed1Δ during infection of oral tissue revealed down-regulation of hyphal associated genes including UME6, encoding another key transcriptional factor. Ectopic overexpression of EED1 or UME6 rescued filamentation and damage potential in eed1Δ. Transcriptional profiling during overexpression of UME6 identified subsets of genes regulated by Eed1 or Ume6. These data suggest that Eed1 and Ume6 act in a pathway regulating maintenance of hyphal growth thereby repressing hyphal-to-yeast transition and permitting dissemination of C. albicans within epithelial tissues.
