Project description:Cryptosporidium is a leading cause of diarrheal disease in children and an important contributor to early childhood mortality. The parasite invades intestinal epithelial cells and remodels them extensively including building an elaborate interface structure. How this occurs at the molecular level is largely unknown. Here, we generated a whole-cell spatial proteome of the Cryptosporidium sporozoite using the spatial proteomics technology hyperLOPIT. These data in combination with genetic and cell-biological experimentation enabled the discovery of the Cryptosporidium secreted effector proteome, including a new secretory organelle.
Project description:Cryptosporidium parvum is one of the most important opportunistic enteric parasites, causing severe diarrhea in immunocomprised human and animals. However, few effective control agents were available for this parasite. circular RNA (circRNA) was discovered to play key roles in many diseases, and the well-known regulatory mechanism for circRNAs is that act as miRNA sponges competitively binding to miRNAs to block miRNA-mRNA interaction. Here, using microarray assay, we investigated the expression profiles of circRNAs in HCT-8 cells after the infection of C. parvum IId subtype, the prevalent subtype of China. A total of 178 circRNAs were dysregulated expressed in HCT-8 cells at 24 h post infection (pi) of C. parvum IId subtype.
