This review covers the sources, ecotoxicities, and removal technologies of MP in soil and water environments reported in previous studies to derive the future research directions for MP removal technologies. Previous studies reported various sources contribute to MP present in soil and water environments, indicating that the source control may be a better strategy than contaminated media treatment for management of MP contamination. Similarly, different terrestrial and aquatic organisms have been used to determine the toxic effects of MP with different characteristics. Previous ecotoxicity studies of MP on soil organisms cover only a small number of species compared to that of MP on aquatic organisms. Therefore, further studies are necessary to investigate the ecotoxic effects of MP on a broader range of soil organisms. Also, since the characteristics of MP are diverse, more ecotoxicity studies in both water and soil environments are required. The review provides an overview of various removal technologies for MP in soil and water and identifies gaps in existing studies. Although more studies have been conducted for removal of MP in water than in soil, they remain in their early stages. More studies are needed for removal of MP removal in soil than in water. With MP in water, most studies have been carried out on a lab scale with artificial wastewaters, thus, studies with natural waters in a pilot or field scale are required. Overall, this review highlights the need for further studies on MP removal technologies for real world applications.</p></div>","PeriodicalId":467,"journal":{"name":"Applied Biological Chemistry","volume":"67 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://applbiolchem.springeropen.com/counter/pdf/10.1186/s13765-024-00957-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142826444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prostate cancer is among the most commonly identified cancers globally and remains a leading cause of cancer-associated deaths in men, often presenting challenges in early detection due to its asymptomatic nature during initial stages. The aim of present study was to determine the biological activity of aloe-emodin obtained from <i>Rheum undulatum</i> L. involving activation of the p53-dependent pathway in certain human prostate cancer cell lines. We explored the mechanisms underlying the anticancer effects of aloe-emodin using LNCaP cells, which include p53-wild type and phosphatase and tensin homolog-deficient mutated genes, a widely studied model in genomic research. Aloe-emodin induced apoptosis in LNCaP cells through several mechanisms, including upregulation of the cleavage of caspase-8 (a cross-linked promoter of cell death signals), phosphorylation of p53 at serine 15, DNA fragmentation, cleavage of poly [ADP-ribose] polymerase, and promotion of cell death. These findings strongly indicated that aloe-emodin's anticancer properties in human prostate cancer involve the activation of p53-induced cellular senescence. Conclusively, the findings of this study imply that aloe-emodin extracted from <i>Rheum undulatum</i> L<i>.</i> is a potential therapeutic compound for adjuvant chemotherapy that induces apoptosis and pyroptosis, an innate immune response, in preventing the progression of precancerous lesions in patients with prostate cancer.</p></div>","PeriodicalId":467,"journal":{"name":"Applied Biological Chemistry","volume":"67 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://applbiolchem.springeropen.com/counter/pdf/10.1186/s13765-024-00956-w","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
