We previously reported that dietary acrylamide, at doses (10 and 50 mg/kg diet) known to cause rodent tumors, lowered serum total high density lipoprotein and total testosterone, increased serum lipase, and lowered lymphocytes levels together with other hematological parameters in male F344 rats exposed for 10 weeks (doi: 10.1016/j.etap.2014.11.009 [1]). Here we present data related to the role of food-borne acrylamide exposure (at 0, 5, 10 and 50 mg/kg diet) in the presence of low (7% wt/wt) or high (23.9% wt/wt) dietary fat on serum and urinary markers of oxidative stress and inflammation in F344 rats. Briefly, urine and serum samples were collected from the experimental animals a day prior to or at the time of necropsy, respectively and processed for enzyme-linked immunosorbent assay estimations of biochemical markers. Urine samples were analyzed for 8-hydroxydeoxyguanosine and isoprostane, and serum samples for total antioxidant capacity, paraoxonase 1 activity, c-reactive protein, homocysteine, oxidized low-density lipoprotein, intercellular adhesion molecule-1, thromboxin 2, and Nε-(carboxymethyl)lysine.
我们之前报道过,膳食中的丙烯酰胺,在已知会导致啮齿动物肿瘤的剂量(10和50毫克/千克饮食)下,会降低雄性F344大鼠血清中总高密度脂蛋白和总睾酮水平,增加血清脂肪酶水平,并降低淋巴细胞水平以及其他血液学参数,这些大鼠暴露于丙烯酰胺10周(doi: 10.1016/j.etap.2014.11.009 [1])。在此,我们展示了在低(7%重量/重量)或高(23.9%重量/重量)膳食脂肪存在的情况下,食源性丙烯酰胺暴露(0、5、10和50毫克/千克饮食)对F344大鼠血清和尿液氧化应激及炎症标志物影响的数据。简而言之,分别在尸检前一天或尸检时从实验动物收集尿液和血清样本,并进行处理以通过酶联免疫吸附测定法估算生化标志物。分析尿液样本中的8-羟基脱氧鸟苷和异前列腺素,以及血清样本中的总抗氧化能力、对氧磷酶1活性、c反应蛋白、同型半胱氨酸、氧化型低密度脂蛋白、细胞间黏附分子-1、血栓素2和Nε-(羧甲基)赖氨酸。
