Despite the rather common presence of humic acid (HA), our full knowledge of its biological effect is still lacking. In this article, we first performed a physicochemical characterization of several HAs, and next, we evaluated their ability to affect interleukin-2 secretion, antibody secretion, wound healing (an in vitro model using HaCaT cells), cancer growth (the Lewis lung carcinoma model), and protection against hepatotoxicity. In all tested reactions, HA showed significant stimulation on immune reactions, including suppression of cancer growth and inhibition of lipopolysaccharide-induced hepatotoxicity. These effects were dependent on its chemical properties. The pleiotropic effects of HA observed in this article suggest the possible role of these compounds in human nutrition.
尽管腐殖酸 (HA) 的存在相当普遍,但我们对其生物学效应的了解仍很欠缺。在本文中,我们首先对几种 HA 进行了理化特性分析,然后评估了它们对白细胞介素-2 分泌、抗体分泌、伤口愈合(使用 HaCaT 细胞的体外模型)、癌症生长(Lewis 肺癌模型)和肝毒性保护的影响。在所有测试的反应中,HA 对免疫反应表现出显著的刺激作用,包括抑制癌症生长和抑制脂多糖诱导的肝毒性。这些作用依赖于其化学特性。本文观察到的 HA 的多效性作用提示这些化合物可能在人类营养中发挥作用。
