Figure Lengend Snippet: MULT1 encoding DNA injection alleviates egg granuloma and hepatic fibrosis in mice infected with Schistosoma japonicum . ( A ) Experimental design. Briefly, 6-week-old BALB/c female mice (n=6 per group) were artificially infected with S. japonicum by cutaneous contact with 24 cercariae on a wet cover slip. Administration of 40 μg rMULT1 DNA or vehicle DNA was carried out via hydrodynamic tail vein injection; the process was initialized at 4 weeks post infection and repeated 3 times in 1 month before the mice were anaesthetized and sacrificed at the end point. ( B ) RT-qPCR data and ( C ) sandwich fluorescence immunoassay showing elevated MULT1 expression in p-rMULT1-injected mice compared with control group mice (GFP-ctl) administered vehicle plasmids. ( D ) Representative H&E staining images (left panel, magnification x200) and quantification of mean (±SEM) egg-induced granuloma size in the liver (white circles). ( E ) Representative Masson’s trichrome staining images (left panel, magnification x200) and quantification of mean (±SEM) collagen deposition (right panel). ( F and G ) RT-qPCR showing decrease of ( F ) liver collagen I and ( G ) α-SMA expression. Western blotting assay demonstrating reduced protein concentration of ( H and I ) collagen I, ( H and J ) α-SMA and ( H and K ) TGF-β in the livers of mice administered rMULT1 DNA. Data are representative of 4–6 animals per subgroup and 3 independent experiments. Comparisons were between rMULT1 and GFP-ctl, *P<0.05 and **P<0.01.
Article Snippet: Briefly, nonionic latex beads (Invitrogen; Thermo Fisher Scientific, Inc.) were coated with 25 μg/mL MULT1 monoclonal antibody (clone 5D10; eBioscience; Thermo Fisher Scientific, Inc.) and blocked with 2% bovine serum album and then incubated with liver tissue lysates and then captured MULT1 was detected by staining with fluorescence labeled detecting antibody specific for MULT1 (clone 237104, R&D Systems, Inc.) and analyzing on FACSVerse or LSRII flow cytometer.
