2-萘酚是一种低分子量 (LMW) 多环芳烃 (PAH) 和与儿童肥胖相关的空气污染物。最近出现了关于多环芳烃对人类健康影响的研究。目前的流行病学报告表明,低分子量多环芳烃可能会导致儿童肥胖发生,但大多数研究都集中在高分子量多环芳烃上。这项研究探讨了 2-萘酚对肥胖和肥胖相关代谢紊乱的影响。为了研究 2-萘酚对脂质代谢和炎症的影响,我们使用 3T3-L1 和 BAT1 细胞系分别模拟白色和棕色脂肪细胞,以及小鼠巨噬细胞系 (RAW264.7)。我们发现,在长期处理的 3T3-L1 和 BAT1 脂肪细胞中,2-萘酚增加了关键脂肪生成和脂肪生成基因的表达,同时降低了脂肪分解基因的表达。此外,长期2-萘酚治疗还抑制BAT1棕色脂肪细胞中肾上腺素刺激的产热基因表达。一致地,BODIPY 和油红 O 染色的脂肪细胞中脂质积累增加。此外,长期暴露于 2-萘酚的 3T3-L1 脂肪细胞和 RAW264.7 巨噬细胞显示主要炎症细胞因子(例如肿瘤坏死因子 α (Tnfα)、白介素-1β (Il-1β) 和 Il-6)的 mRNA 表达上调。总之,长期接触 2-萘酚会刺激脂肪细胞中的脂质积累以及脂肪细胞和巨噬细胞中的炎症。这些发现支持了先前的研究,证明 2-萘酚具有致肥潜力。
2-naphthol is a low-molecular-weight (LMW) polycyclic aromatic hydrocarbon (PAH) and air pollutant associated with childhood obesity. There has been a recent emergence of studies on the consequences of PAHs on human health. Current epidemiological reports suggest LMW-PAHs may contribute to obesity incidences in children, yet most studies focus on high-molecular-weight PAHs. This study explores 2-naphthol’s impact on obesity and obesity-associated metabolic disorders. To investigate 2-naphthol’s effect on lipid metabolism and inflammation, we employed 3T3-L1 and BAT1 cell lines to model white and brown adipocytes, respectively, alongside a murine macrophage cell line (RAW264.7). We found that 2-naphthol increased the expression of key adipogenic and lipogenic genes while decreasing lipolytic gene expression in chronically treated 3T3-L1 and BAT1 adipocytes. In addition, chronic 2-naphthol treatment also suppressed adrenergic-stimulated thermogenic gene expression in BAT1 brown adipocytes. In consistence, an increase in lipid accumulation was demonstrated in BODIPY and Oil Red O-stained adipocytes. Additionally, 3T3-L1 adipocytes and RAW264.7 macrophages chronically exposed to 2-naphthol showed upregulated mRNA expression of major inflammatory cytokines (e.g., tumor necrosis factor α (Tnfα), interleukin-1β (Il-1β), and Il-6). In summary, chronic exposure to 2-naphthol stimulates lipid accumulation in adipocytes and inflammation in adipocytes and macrophages. These findings support previous research that demonstrates 2-naphthol has obesogenic potential.
