Cur@α-NTP-LNs delayed the progression of NPC lung metastasis. a Schematic diagram of Cur@α-NTP-LNs treatment on NPC lung metastasis. b X-ray computed tomography scan for the detection of pulmonary metastases in normal mice and mice after treatment with PBS or 125 nmol of free Cur, Cur equivalent Cur@α-NTP-LNs or peptide equivalent α-NTP-LNs at day 25 after 5-8F cell injection. c Histopathological analyses of H&E-stained lung tissues from mice treated with Cur@α-NTP-LNs, α-NTP-LNs, Cur or PBS at day 25 after 5-8F cell injection. Scale bar = 50 µm. d Survival curve of mice with NPC lung metastases after treatment with PBS or 125 nmol free Cur, Cur equivalent Cur@α-NTP-LNs or peptide equivalent α-NTP-LNs (n = 5)
