Nevertheless, the proliferation rate evaluated by Ki-67 positive cells was drastically decreased in the tumor areas exposed to NX (bold asterisk, Figure 5A,f and i) compared to control or TSP-1 (p=0.0004; Figure 5A,d, 5A,g and 5A,e, 5A,h and 5B). The gene discussed is THBS1; the disease is neoplasm.
