The development of new drugs for the inhibition of hepatocellular carcinoma (HCC) development and progression is a critical and urgent need. The median survival rate for HCC patients remains disappointingly low. Vinpocetine is a safe nootropic agent that is often used to enhance cognitive function. The impact of vinpocetine on HCC development and progression has not been fully explored. Our main objective was to investigate the possible inhibitory role of vinpocetine in rats exposed to diethylnitrosamine. We observed that vinpocetine increased the survival rate of these rats and improved the ultrastructure of their livers. Additionally, vinpocetine reduced the liver weight index, mitigated liver oxidative stress, and improved liver function. In both in vitro and in vivo settings, vinpocetine demonstrated antiproliferative and apoptotic properties. It downregulated the expression of CCND1 and Ki-67 while exhibiting anti-BCL-2 effects and enhancing the levels of Bax and cleaved caspase-3. Vinpocetine also successfully deactivated NF-κB, STAT3, and HIF-1α, along with their associated transcription proteins, thereby exerting anti-inflammatory and anti-angiogenic role. Furthermore, vinpocetine showed promise in reducing the levels of ICAM-1 and TGF-β1 indicating its potential role in tissue remodeling. These findings strongly suggest that vinpocetine holds promise as a hepatoprotective agent by targeting a range of oncogenic proteins simultaneously. However, further approaches are needed to validate and establish causal links between our observed effects allowing for a more in-depth exploration of the mechanisms underlying vinpocetine's effects and identifying pivotal determinants of outcomes.
开发抑制肝细胞癌(HCC)发展和进展的新药是一项至关重要且紧迫的需求。 HCC 患者的中位生存率仍然令人失望地低。长春西汀是一种安全的益智药,常用于增强认知功能。长春西汀对 HCC 发展和进展的影响尚未得到充分探索。我们的主要目标是研究长春西汀对二乙基亚硝胺暴露大鼠的可能抑制作用。我们观察到长春西汀提高了这些大鼠的存活率并改善了其肝脏的超微结构。此外,长春西汀降低了肝重指数,减轻了肝氧化应激,改善了肝功能。在体内和体外环境中,长春西汀均表现出抗增殖和凋亡作用。它下调了 CCND1 和 Ki-67 的表达,同时表现出抗 BCL-2 作用,并增强了 Bax 和 cleaved caspase-3 的水平。长春西汀还成功地使 NF-κB、STAT3 和 HIF-1α失活,以及它们相关的转录蛋白,从而发挥抗炎和抗血管生成作用。此外,长春西汀降低了 ICAM-1 和 TGF-β1 的水平,表明其在组织重塑方面具有潜力。这些发现强烈表明,长春西汀通过同时针对多种致癌蛋白,有望成为一种肝保护剂。然而,需要进一步的方法来验证和建立我们观察到的效果之间的因果关系,以便更深入地探讨长春西汀作用的机制,并确定结果的关键决定因素。
