Project description:We compared the gene expression stimulated with fungal extracts from Aspergillus (A.) fumigatus, Alternaria (A.) alternata, or Penicillium (P.) notatum in NCI-H292 (a human bronchial epithelial cell line) to search Allergic bronchopulmonary mycosis (ABPM)-related genes. We identified a mucin-related MUC5AC gene, the expression of which was selectively induced by A. fumigatus.

Total RNA from NCI-H292 cells stimulated for 24 h with the A. fumigatus, A. alternata, or P. notatum fungi extracts was extracted and subjected to microarray analysis. Each experiments were perfomed once for each stimulus.

Project description:Eosinophilia is associated with various persisting inflammatory diseases and often coincides with chronic fungal infections or fungal allergy as in case of allergic bronchopulmonary aspergillosis (ABPA). However, the interactions between eosinophils and fungal pathogen leading to release of inflammatory mediators from eosinophils are poorly understood. Therefore, we established a co-culture system of mouse bone marrow derived eosinophils (BMDE) with Aspergillus fumigatus (Af) that we used in part to analyse transcriptional regulation induced by Af.

Project description:Purpose: Aflatoxin B1 is the most toxic and carcinogenic compound in nature produced by Aspergillus fungi. In our study, we applied RNA-seq to compare the transcriptomic profiles of Aspergillus flavus strains in the presence and absence of medicinal plant Zanthoxylum bungeanum. Methods: mRNA profiles of Aspergillus flavus supplemented with 250 µg/ml of methanolic extract fraction (treated samples) or DMSO (control samples) were generated in triplicate, by an Illumina platform using paired-end 150 bp sequencing strategy. Clean paired-end reads were mapped to the reference genome of A. flavus NRRL3357. Gene expression quantification was calculated by FPKM (Fragments Per Kilobase of transcript sequence per Millions base pairs sequenced). The differentially expressed genes (DGEs) between the control and test samples were analyzed using the DESeq2 R package. Results: RNA-seq produced 24.5–32.1 million clean paired-end reads (150 bp read length) per sample and most of them (83–91%) were uniquely mapped to the reference genome of A. flavus NRRL3357. Eighty-two percent of genes displayed FPKM value ≥1 and were thus classified as expressed genes. Ninety-six percent of the expressed genes were expressed both in the control and test groups whereas 2.3% and 1.8% of the genes were expressed only in the control or test group, respectively. With the combination of FPKM fold change ≥2 and adjusted p-value <0.05, we found in total 950 DEG’s. Among them, 515 genes were downregulated and 435 genes were upregulated. We used FungiFun software to analyze the functions of the DEGs based on FunCat pathways and categories. About half of the DEG’s had a relevant annotation in the FunCat database, and 60–70% of the annotated DEG’s were found to be enriched in specific functional pathways. Conclusions: we showed that simple organic extracts from Z. bungeanum inhibit both the growth and aflatoxin production by Aspergillus flavus. The repression of AF pathway is mediated by global regulators instead of pathway specific regulators AflR or AflS. Consistently, the expression of Velvet complex, a prominent regulator of fungal secondary metabolism and development, was substantially reduced. Natural compound extracts from Z. bungeanum have potential to facilitate the development of safe and economical control strategies that shutdown aflatoxin production in aflatoxigenic Aspergillus species.

Project description:Most of Colorectal cancer (CRC) diagnosed are candidates for surgical resection with curative intent, although colorectal surgery is associated with some complications that could be life-threatening. Antibiotic prophylaxis is commonly used prior to the admission for the prevention of postoperative complications. However, this intervention can change the composition of intestinal microbiota and promote adverse inflammatory outcomes in CRC patients after surgery.
It seems the combination of different fungal extracts could be beneficial because of their role in gut microbiota modulation and their anti-inflammatory activity. Therefore, the fungal extract nutraceutical MICODIGEST 2.0 could be used to reduced the complications after CRC surgery.
Based on this hypothesis, we have designed a double-bind randomized clinical trial to evaluate the effect of MICODIGEST 2.0 on the complications after surgery with curative intent for CRC.
