In a study conducted by Naik et al. (2021), they created a peptidomimetic conjugate (SA-5)-tagged Dox incorporated liposome (LP) formulation (SA-5-Dox-LP) to assess the targeted delivery potential of SA-5 in HER2-overexpressed non-small-cell lung cancer (NSCLC) and breast cancer cell lines. Here, ERBB2 is linked to non-small cell lung carcinoma.
