Project description:Cryptosporidiosis is a zoonotic disease caused by infection with the oocyst of Cryptosporidium in human and animals. MicroRNA (miRNA) emerges as important player in regulating the innate immune response against parasitic infection. Here, we compared miRNA profiles of the glandular stomach of Cryptosporidium muris (C. muris) infected and un-infected BALB/c mice using microarray sequencing. A total of 10 miRNAs (including 3 upregulated and 7 downregulated miRNAs) with significant expression differences (|FC| ≥ 2 and P value test < 0.05) were screened after C. muris infected the glandular stomach of BALB/c mice for 8 hours. MiRWalk and miRDB online bioinformatics software were used to predict the target genes of differentially expressed miRNAs. Gene Ontology (GO) and KEGG enrichment analyses were performed for annotate the target genes. GO terms indicates that many are associated with the relevant generic transcription and ion transport. In addition, the KEGG analyses showed that the target genes were strictly related to a diverse types of tumor disease progression and the antipathogen immunity pathway. In the current study, we first reported the changes of miRNA expression profile in glandular stomach of BALB/c mice at the early phase of C. muris invasion. As such, dysregulation of miRNA expression profile may contribute to our understanding of the Cryptosporidiosis pathology. The result reported in this paper provide a new perspective into the miRNA regulatory mechanisms of Cryptosporidiosis, which may help to develop effective control strategies against Cryptosporidium.

Project description:Cryptosporidium parvum has been reported to induce digestive adenocarcinoma in a rodent model of chronic cryptosporidiosis. In the current study, the transcriptomes of C. parvum infected ileo-caecal regions of mice developing tumours were analysed to identifie potential genes involved in development of cancer

Project description:It has been reported that Cryptosporidium parvum, a species of a protozoan frequently isolated from humans and animals, is able to induce digestive adenocarcinoma in a rodent model. Consistently, some epidemiological studies have reported an association with cryptosporidiosis in patients with colorectal adenocarcinoma. However, the correlation between cryptosporidiosis and human digestive cancer remains unclear at this time, and it is not known whether this intracellular parasite, considered an opportunistic agent, is able to induce gastrointestinal malignancies in humans. In order to add new arguments for a probable association between cryptosporidiosis and digestive human cancer, the main aim of this study is to determine prevalence and to identify species of Cryptosporidium among a French digestive cancer population.

Project description:Cryptosporidium parvum is an important zoonotic parasitic disease worldwide, but the molecular mechanisms of the host–parasite interaction are not fully understood. Noncoding microRNAs (miRNAs) are considered key regulators of parasitic diseases. Therefore, we used microarray, qPCR, and bioinformatic analyses to investigate the intestinal epithelial miRNA expression profile after Cryptosporidium parvum infection.Twenty miRNAs were differentially expressed after infection (four upregulated and 16 downregulated). Further analysis of the differentially expressed miRNAs revealed that many important cellular responses were triggered by Cryptosporidium parvum infection, including cell apoptosis and the inflammatory and immune responses.This study demonstrates for the first time that the miRNA expression profile of human intestinal epithelium cells is altered by C. parvum infection. This dysregulation of miRNA expression may contribute to the regulation of host biological processes in response to C. parvum infection, including cell apoptosis and the immune responses. These results provide new insight into the regulatory mechanisms of host miRNAs during cryptosporidiosis, which may offer potential targets for future C. parvum control strategies.
