Project description:Graviola (Annona muricata) is a tropical plant with many traditional ethnobotanic uses and pharmacologic applications. A metabolomic study of both aqueous and DMSO extracts from Annona muricata leaves recently allowed us to identify dozens of bioactive compounds. In the present study, we use a proteomic study to reveal new bioactivities of these leave extracts on both conditioned media and extracts of HT-1080 fibrosarcoma treated cells. Our results reveal the complete sets of deregulated proteins after treatment with aqueous and DMSO extracts from An-nona muricata leaves. Functional enrichment analysis of proteomic data suggests deregulation of cell cycle and iron metabolism, which are experimentally validated. Additional experimental data reveal that these extracts protect from ferroptosis to both HT-1080 fibrosarcoma cells and HMEC-1 endothelial cells.

Project description:Specific recognition and bacterial adhesion to host cells by uropathogenic E. coli (UPEC) are the first steps towards infection of epithelial tissue of the human urogenital system. Therefore, targeting of UPEC virulence factors, relevant for adhesion, is a promising approach for prevention of recurrent urinary tract infections (UTI). A fully characterized plant-derived aqueous extract from the leaves of Orthosiphon stamineus (OWE), a plant traditionally used in clinical practice in Europe and Asia for UTI, has been shown to exert strong antiadhesive effects under in vitro and in vivo conditions. For improved understanding of the underlying mechanisms transcriptome analysis of OWE-treated UPEC strain UTI89 by Illumina sequencing and cross-validation of these data by qPCR indicated significant down-regulation of bacterial adhesins (curli, type 1-, F1C- and P fimbriae) and of the chaperone-mediated protein folding/unfolding and pilus assembly process; in contrast flagellar and motility-related genes were upregulated. We conclude that OWE transforms the sessile lifestyle of bacteria into a motile one and therefore disables bacterial attachment to the host cell. Additionally, the extract inhibited gene expression of multiple iron acquisition systems (Ent, Fep, Feo, Fhu, Chu, Sit, Ybt) concomitant with an upregulated expression of the ferric uptake regulator (Fur) repressor. The present study explains the antiadhesive and antiinfective effect of the plant extract by pinpointing specific biochemical and molecular targets.
