چکیده انگلیسی
The food and water we consume may be contaminated with a range of chemicals and heavy metals, such as lead, cadmium, arsenic, chromium, and mercury by accumulation through the food chain. Cadmium is known to be one of the major components in cigarette smoke and can cause lesions in many organs. Some lactobacilli can bind and remove heavy metals such as cadmium, lead, and copper. However, the mechanisms of cadmium toxicity and inhibition by probiotics are not clear. In this study, we demonstrated that glycoprotein (18 kDa) isolated from Lactobacillus plantarum L67 protected RAW 264.7 cells from expression of inflammation-related factors stimulated by cadmium chloride (100 µM). Furthermore, we evaluated the cytotoxicity of cadmium using the MTT assay and intracellular Ca2+ using fluorescence, and assessed activities of activator protein kinase C (PKC-α), inducible nitric oxide synthase, activator protein (AP)-1, and mitogen-activated protein kinases using immunoblot. Our results indicated that glycoprotein isolated from L. plantarum L67 inhibited intracellular Ca2+ mobilization. It also significantly suppressed inflammatory factors such as AP-1 (c-Jun and c-Fos), mitogen-activated protein kinases (ERK, JNK, and p38), and inducible nitric oxide synthase. Our findings suggest that the 24-kDa glycoprotein isolated from L. plantarum L67 might be used as a food component for protection of inflammation caused by cadmium ion.
