To examine the effects of pericyte FAK-Y397F and Y861F mutations on tumour growth and angiogenesis, PdgfrβCre + ;FAKWT/WT control mice, PdgfrβCre + ;FAKY861F/Y861F and PdgfrβCre + ;FAKY397F/Y397F mice were injected subcutaneously with Lewis Lung Carcinoma cells (LLC). The gene discussed is PTK2; the disease is Carcinoma, Lewis Lung.
