Autophagy is a self‐eating pathway for maintaining normal cellular physiology, while dysregulation of autophagy is associated with cancer progression. Autophagy‐related 4B gene (ATG4B) is a cysteine protease to regulate autophagosome formation and is positively correlated with poor prognosis of colorectal cancer (CRC) patients. An increasing number of reports have implied that ATG4B might be an attractive drug target for CRC. Natural products are the most important source of drug development for cancer therapy due to their high degree of diversity in chemical structure. However, there are few natural products targeting autophagy regulation, especially targeting ATG4B. We aim to identify effective natural compounds from costal plants against ATG4B as potential CRC therapies. We extracted the whole plants, stem, and leaves from nine coastal plant species of Taiwan using different solvents including acetone, methanol, or chloroform. We then evaluated their effects on ATG4B activity and cancer malignancy in CRC cells (DLD‐1, HCT116, and SW620). Among these 26 extracts, we found that the methanol leaf extract of A. elliptifolia significantly inhibited ATG4B proteolytic activity. Moreover, cell viability and colony formation and mobility were decreased in CRC cells treated with the extract. The extract further reduced the number of living cells and induced subG1 proportion of CRC cells. The cytotoxicity of A. elliptifolia leaf extract was also enhanced in CRC cells under starvation, whereas it had no additional effects in ATG4B or autophagy deficient cells. Taken together, the methanol leaf extract of A. elliptifolia might contains bioactive compounds for inhibiting ATG4B and autophagy activity to diminish viability and mobility of CRC cells, indicating its potential as an anti‐CRC drug for future development.

Clothianidin (CLO) is a high-frequently detected neonicotinoid pesticide in fruits and vegetables, whose exposure security deserves attention. This study evaluated the apoptotic toxicity of CLO on Caco-2 cells at doses of 100 nM, 10 μM, and 1 mM. After exposure, CLO induced to a remarkable change of signaling proteins that participated in the process of cell apoptosis, including caspase 3, cleaved-caspase 3, and caspase 9. CLO treatment further induced a decrease of mitochondrial membrane potential and increased the protein level of cytochrome C. Reactive oxygen species (ROS) and intracellular Ca2+ were also found elevated, indicating an oxidative damage caused by CLO treatment. Moreover, the production of ROS occurred in advance of Ca2+ elevation, since inhibiting ROS production could recover the elevation of Ca2+ induced by CLO exposure. The protein level of metabolic enzyme cytochrome P450 3A4 (CYP3A4) was downregulated after the treatment of CLO. Molecular docking simulation indicated that CLO had good binding characteristics with CYP3A4. Amino acid sites Arg105, Arg130, and Leu373 in CYP3A4, and nitro group and chlorothiazole group in CLO structure might be the potential binding action target. These results indicated that CLO exposure could induce an apoptotic effect on Caco-2 cells, possibly acting through combining and inhibiting its metabolic enzyme CYP3A4, and then leading to oxidative stress and mitochondrial damage. Thus, CLO exposure might be a potential risk factor for human intestinal health.

Molecular docking simulation indicated that CLO had good binding characteristics with CYP3A4. Amino acid sites Arg105, Arg130, and Leu373 in CYP3A4, and nitro group and chlorothiazole group in CLO structure might be the potential binding action target. These results indicated that CLO exposure could induce an apoptotic effect on Caco-2 cells, possibly acting through combining and inhibiting its metabolic enzyme CYP3A4, and then leading to oxidative stress and mitochondrial damage. Thus, CLO exposure might be a potential risk factor for human intestinal health.</p>","PeriodicalId":11756,"journal":{"name":"Environmental Toxicology","volume":" ","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142692821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increasing incidence of cancer underscore the necessity of investigating contributors such as endocrine-disrupting chemicals (EDCs), including bisphenol A (BPA). Although BPA's risks are well-documented, comprehensive studies on its substitutes, such as bisphenol B (BPB), are limited. Dysregulated lipid metabolism is a hallmark of cancer progression. Our previous work demonstrated that BPA and bisphenol S (BPS) disrupt lipid metabolism via the peroxisome proliferator-activated receptor γ (PPARγ) pathway. We hence hypothesized that BPB might similarly perturb lipid metabolism and promote tumor growth. BPB's impact on lipid metabolism was investigated in vitro and in vivo using B16 melanoma cancer cells. Our findings indicate BPB exposure significantly increased lipid metabolism in B16 cells, enhancing cell proliferation and migration, and promoting tumor development in mice. Utilizing siRNA transfection or chemical inhibitor, we found that stearoyl-CoA desaturase-1 (SCD1), a key enzyme in lipid synthesis pathway, was required for BPB-induced lipid accumulation and cancer cell migration. Docking analysis revealed BPB may activate gene expression related to lipid metabolism and angiogenesis by interacting with PPARγ and hypoxia-inducible factor-1α (HIF-1α). This study illuminates BPB's potential role in advancing melanoma through lipid metabolism manipulation, highlighting the need for further research into the safety of BPA substitutes and their impact on cancer development.
癌症发病率的不断上升突出表明,有必要对包括双酚 A (BPA) 在内的干扰内分泌的化学品 (EDC) 等致癌物质进行调查。尽管双酚 A 的风险已得到充分证实,但对其替代品(如双酚 B (BPB))的全面研究却十分有限。脂质代谢失调是癌症发展的一个标志。我们之前的研究表明,双酚 A 和双酚 S(BPS)通过过氧化物酶体增殖激活受体γ(PPARγ)途径破坏脂质代谢。因此,我们推测 BPB 可能同样会扰乱脂质代谢并促进肿瘤生长。我们使用 B16 黑色素瘤癌细胞对 BPB 对脂质代谢的影响进行了体外和体内研究。我们的研究结果表明,暴露于 BPB 会明显增加 B16 细胞的脂质代谢,增强细胞增殖和迁移,促进小鼠肿瘤的发展。利用 siRNA 转染或化学抑制剂,我们发现硬脂酰-CoA 去饱和酶-1(SCD1)是脂质合成途径中的一个关键酶,是 BPB 诱导脂质积累和癌细胞迁移所必需的。对接分析表明,BPB 可通过与 PPARγ 和缺氧诱导因子-1α(HIF-1α)相互作用,激活与脂质代谢和血管生成相关的基因表达。这项研究揭示了 BPB 通过操纵脂质代谢在促进黑色素瘤发展方面的潜在作用,强调了进一步研究双酚 A 替代品的安全性及其对癌症发展的影响的必要性。
