Helicobacter pylori infection induces high expression of PLK1 in gastric tissue from Mongolian gerbils. (A) Gastric tissue sections from H. pylori-infected gerbils were stained with antibodies against PLK1. (B) Immunoreactive cells were semi quantitatively assessed and the protein expression levels are expressed as grade 1–4. Mean grades () for protein expression are shown. *p<0.05; **p<0.01; ***p<0.001.
Abbreviation: PLK1, polo-like kinase 1.
