The inhibition of angiogenesis is a crucial therapeutic strategy in cancer treatment, as it limits tumor growth and metastasis. In this study, we investigate the anti-angiogenic potential of a novel htsFLT01/MiRGD nanocomplex, designed to target key angiogenesis markers in cancer. This nanocomplex integrates the anti-angiogenic fusion protein htsFLT01 with the MiRGD peptide to enhance its efficacy. Our findings demonstrate that htsFLT01/MiRGD effectively suppresses angiogenesis both in vitro and in vivo, particularly in breast cancer models. Histological and molecular analyses reveal a significant reduction in blood vessel formation, accompanied by structural changes in tumor tissue. Furthermore, the expression levels of key angiogenesis-related genes, including VEGF, VEGFR, and CD31, are markedly downregulated, highlighting the therapeutic potential of this nanocomplex. Beyond its anti-angiogenic effects, the treatment also induces apoptosis and inhibits tumor cell proliferation, reinforcing its role as a promising targeted therapy for angiogenesis-dependent malignancies. These results underscore the potential of htsFLT01/MiRGD in cancer treatment and pave the way for future clinical applications in anti-angiogenic therapies.
