Comparable biodistribution patterns were observed in another study by Shao and co-workers, where the in vivo and in vitro comparative characterisation of NGR ([68Ga]Ga-NOTA-G3-NGR2) and RGD-based ([68Ga]Ga-NOTA-G3-RGD2) radiopeptides was carried out in HT1080 tumour xenografts (as presented in Table 1) [37]. This evidence concerns the gene RTN4RL2 and neoplasm.
