Abstract

Hepatocellular carcinoma (HCC) can be produced from aflatoxin B1 (AFB1) administration. Although berberine (BER) acts as an anticancer agent and can counteract the AFB1 effect, it has low bioavailability. Nanotechnology can overcome this problem. This research aimed to synthesize berberine nanoparticles (NPs) and then estimate their therapeutic effect compared to that of berberine against aflatoxin-induced hepatotoxicity. The desolvation method was used to prepare BER-NPs. Aflatoxicosis was induced by 5 consecutive intraperitoneal injections (IP) of 200 µg/kg/day AFB dissolved in dimethylsulfoxide (DMSO). After the induction period, two treatments were performed: the first with 100 mg/kg BER and the second with 10 mg/kg BER-NPs. Liver, kidney, and diabetic profiles were estimated by using standardized methods. Hepatic oxidative stress, inflammatory, cancer cell proliferation, and invasion markers were used by ELISA and qPCR techniques. The TEM image shows that both BSA NPs and BER-BSA NPs had spherical, regular, and uniform shapes. The BER encapsulation efficiency % was 78.5. The formed-BER-BSA NPs showed a loading capacity % of 7.71 and the synthesis yield % of 92.6. AFB1 increases pro-oxidant markers, decreases antioxidant systems, stimulates inflammatory enzymes, inhibits anti-inflammatory markers, decreases tumor suppressor enzymes, increases oncogenes, increases glycolytic activity, prevents cell death, and promotes cell growth. Most of the biochemical markers and hepatic architecture were normalized in the BER-BSA NP-treated group but not in the BER-treated group. Altogether, the obtained data proved that treatment with BER-NPs was more efficient than treatment with berberine against aflatoxicoses induced in rats.

摘要

肝细胞癌(HCC)可由黄曲霉毒素 B1(AFB1)给药产生。虽然小檗碱(BER)作为一种抗癌剂,可以对抗 AFB1 的作用,但它的生物利用度较低。纳米技术可以克服这个问题。本研究旨在合成小檗碱纳米颗粒(NPs),然后估计其治疗效果与小檗碱对黄曲霉毒素诱导的肝毒性的治疗效果相比。采用去溶剂法制备 BER-NPs。通过连续 5 次腹腔注射(IP)200 µg/kg/天 AFB1 溶于二甲基亚砜(DMSO)诱导黄曲霉病。诱导期后,进行两种治疗:第一种用 100 mg/kg BER,第二种用 10 mg/kg BER-NPs。采用标准化方法估计肝、肾和糖尿病谱。通过 ELISA 和 qPCR 技术测定肝氧化应激、炎症、癌细胞增殖和侵袭标志物。TEM 图像显示 BSA NPs 和 BER-BSA NPs 均具有球形、规则和均匀的形状。BER 包封效率为 78.5%。形成的 BER-BSA NPs 的载药量为 7.71%,合成产率为 92.6%。AFB1 增加促氧化剂标志物,降低抗氧化系统,刺激炎症酶,抑制抗炎标志物,降低肿瘤抑制酶,增加癌基因,增加糖酵解活性,阻止细胞死亡并促进细胞生长。BER-BSA NP 处理组的大多数生化标志物和肝结构均得到正常化,但 BER 处理组则未得到正常化。总之,所得数据证明,与黄曲霉毒素诱导的大鼠相比,BER-NPs 的治疗效果优于小檗碱。
