Abstract
BACKGROUND One of the causes of antibiotic resistance is the reduced accumulation of antibiotics in bacterial cells through pumping out the drugs. Silybin, a key component of the Silybum marianum plant, exhibits various beneficial properties, including anti-bacterial, anti-inflammatory, antioxidant, and hepatoprotective effects. METHODS AND RESULTS Clinical isolates of E. coli were procured from 17 Shahrivar Children's Hospital in Rasht, Guilan, located in northern Iran. Their susceptibility to six antibiotics was assessed using disc diffusion and broth dilution (MIC) methods. The antibacterial effects of silybin-loaded polymersome nanoparticles (SPNs) were investigated with broth dilution (MIC) and biofilm assays. Molecular docking was utilized to evaluate silybin's (the antibacterial component) binding affinity to efflux pumps, porins, and their regulatory elements. Additionally, qRT-PCR analysis explored the expression patterns of acrA, acrB, tolC, ompC, and ompF genes in both SPNs (sub-MIC) and ciprofloxacin (sub-MIC)-treated and untreated E. coli isolates. The combined use of SPNs and ciprofloxacin exhibited a notable reduction in bacterial growth and biofilm formation, in ciprofloxacin-resistant isolates. The study identified eight overlapping binding sites of the AcrABZ-TolC efflux pump in association with silybin, demonstrating a binding affinity ranging from -7.688 to -10.33 Kcal/mol. Furthermore, the qRT-PCR analysis showed that silybin upregulated AcrAB-TolC efflux pump genes and downregulated ompC and ompF porin genes in combination with ciprofloxacin in transcriptional level in uropathogenic E. coli. CONCLUSIONS Silybin, a safe herbal compound, exhibits potential in inhibiting antibiotic resistance within bacterial isolates, potentially through the regulation of gene expression and plausible binding to target proteins.
