On the contrary, no remarkable difference was shown between the T/M ratios of the NOTA-linked [68Ga]Ga-labelled dimeric Gly3-CNGRC cyclic peptide ([68Ga]Ga-NOTA-G3-NGR2) and [68Ga]Ga-NOTA-G3-RGD2 in the study of Shao et al. applying female BALB/c mice bearing HT1080 tumours with simultaneous expression of APN/CD13 and ανβ3/ανβ5 integrin [37,55,56]. This evidence concerns the gene RTN4RL2 and neoplasm.
