Sandeep Rajput et al. [27] reported that the growth rate of breast cancer (BC) in nude mice inoculated with breast cancer cells transfected with TLR-4 overexpression plasmids was significantly higher than that in the control group of nude mice inoculated with breast cancer cells transfected with TLR-4 silencing plasmids. The gene discussed is TLR4; the disease is breast cancer.
