Lentinula edodes C91-3 is an edible mushroom that has demonstrated a remarkable anti-tumor effect in various cancer cells both in vitro and in vivo. In the present study, we report the ability of recombinant thioredoxin-like latcripin 11 (LP-11) of Lentinula edodes C91-3 to suppress the proliferation of various cancer cells. The LP-11 gene of Lentinula edodes C91-3 was cloned in the pET-32a( +) expression vector and expressed in a prokaryotic system. The expressed protein was refolded by gradual dialysis and purified by affinity gel filtration chromatography. The antioxidant activity of LP-11 was tested by 1,1-dipheny1-2-picrylhydrazyl (DPPH) assay. The antitumor activity of recombinant LP-11 was tested in eight kinds of tumor cell lines by CCK-8 assay. Recombinant LP-11 significantly suppressed the proliferation of various cancer cells, but not normal human umbilical vein endothelial cells. Human lymphoma U937 cells exhibited the most sensitivity to LP-11 protein. U937 cell apoptosis was assessed by Annexin V staining coupled with flow cytometry, and mitochondrial morphology was analyzed by light and electron microscopy. It was revealed that recombinant LP-11 induced apoptosis in human leukemic monocyte lymphoma U937 cells. Our findings suggest that recombinant LP-11 is a promising agent for the treatment of lymphoma.
