Meanwhile, based on the results from Western blot analysis, compared with those in response to PBS treatment, the protein expression of p65, extent of p65 phosphorylation, CD133, EpCAM, Nanog, Oct-4, Sox-2, and Bcl-2 in tumor tissues was significantly increased in the presence of LPS, while a notable decrease in the protein expression of Bax was observed. The gene discussed is BCL2; the disease is neoplasm.
