Abstract
Hepatocellular carcinoma (HCC) is a leading cause of death globally. Even though the progressive invention of some very potent therapeutics has been seen, the success is limited due to the chemotherapeutic resistance and recurrence in HCC. Advanced targeted treatment options like immunotherapy, molecular therapy or surface-engineered nanotherapeutics could offer the benefits here owing to drug resistance over tumor heterogenicity. We have developed tumor-sensing phosphorothioate and amino-modified aptamer (AS1411)-conjugated stealth nanoliposomes, encapsulating with apigenin for precise and significant biodistribution of apigenin into the target tumor to exploit maximum bio-therapeutic assistances. The stable aptamer functionalized PEGylated nanoliposomes (Apt-NLCs) had an average vesicle size of 100-150 nm, a smooth surface, and an intact lamellarity, as ensured by DLS, FESEM, AFM, and Cryo-TEM. This study has specified in vitro process of optimum drug (apigenin) extrusion into the cancer cells by nucleolin receptor-mediated cellular internalization when delivered through modified AS1411 functionalized PEGylated nanoliposomes and ensured irreversible DNA damage in HCC. Significant improvement in cancer cell apoptosis in animal models, due to reduced clearance and higher intratumor drug accumulation along with almost nominal toxic effect in liver, strongly supports the therapeutic potential of aptamer-conjugated PEGylated nanoliposomes compared to the nonconjugated formulations in HCC. The study has established a robust superiority of modified AS1411 functionalized PEGylated nanoliposomes as an alternative drug delivery approach with momentous reduction of HCC tumor incidences.
