Other pathways such as; TGF-beta signalling pathway [13], VEGF signalling pathway [14], Neurotrophin signalling pathway [15], Focal adhesion [16], Extracellular matrix activity [17], Adherens junction [18], p53 signalling pathway [19], Notch signalling pathway [20] are described as being active at thyroid cancer pathogenesis. This evidence concerns the gene TP53 and thyroid cancer.
