For example, expression and clinical significance of tumour suppressor gene solute carrier family 22 (organic cation transporter), member 18 (SLC22A18), in non-small cell lung cancer [75] and protein tyrosine phosphatase type IVA, member 3 (PTP4A3) gene in VEGF signalling and the process of pathological angiogenesis [76] has been reported previously. This evidence concerns the gene PTP4A3 and non-small cell lung carcinoma.
