Project description:PM2.5 can harm various systems in the human body. However, due to the limitations of epidemiology and toxicology, the disease types, shared and specific pathogenic mechanisms induced by PM2.5 in various human systems are not comprehensive and in-depth revealed. Thus, this study conducted an analysis on the aforementioned issues in respiratory, circulatory, endocrine, female, and male urogenital systems. According to this study, PM2.5 was more likely to induce pulmonary emphysema, reperfusion injury, malignant neoplasm of thyroid, endometriosis of ovary, nephritis in above each system respectively. FOS, extracellular matrix, urogenital system development, extracellular matrix structural constituent conferring tensile strength, and ferroptosis was the most important co-existing gene, cellular component, biological process, molecular function, and pathway in five systems targeted by PM2.5. Furthermore, BTG2, BIRC5, NFE2L2, TBK1, and STAT1 were significantly uniquely targeted by PM2.5 in each system respectively. Important disease related cellular component, biological process, and molecular function were highly specially induced by PM2.5, such as response to wounding, blood vessel morphogenesis, body morphogenesis, negative regulation of response to endoplasmic reticulum stress, and response to type I interferon were the top 1 uq-existing biological processes in each system respectively. PM2.5 highly specially acted on the key disease related pathway, such as PD-L1 expression and PD-1 checkpoint pathway in cancer (respiratory), cell cycle (circulatory), apoptosis (endocrine), antigen processing and presentation (female), and neuroactive ligand-receptor interaction (male). This study provides a new analysis method to clarify PM2.5-related disease types, which is an important supplement to epidemiological investigation. Furthermore, this study has clarified the risks of PM2.5 exposure, elucidated the pathogenic mechanisms, and provided scientific support for promoting precise prevention and treatment of PM2.5-related diseases.

Project description:Forty-six percent of the world's population resides in rural areas, the majority of whom belong to vulnerable and low-income groups. They mainly use cheap solid fuels for cooking and heating, which release a large amount of PM2.5 and cause adverse effects to human health. PM2.5 exhibits urban-rural differences in its health risk to the respiratory system. However, the majority of research on this issue has focused on respiratory diseases induced by atmospheric PM2.5 in urban areas, while rural areas have been ignored for a long time, especially the pathogenesis of respiratory diseases. This is not helpful for promoting environmental equity to aid low-income and vulnerable groups under PM2.5 pollution. Thus, this study focuses on rural atmospheric PM2.5 in terms of its chemical components, toxicological effects, respiratory disease types, and pathogenesis, represented by PM2.5 from rural areas in the Sichuan Basin, China (Rural SC-PM2.5). In this study, organic carbon is the most significant component of Rural SC-PM2.5. Rural SC-PM2.5 significantly induces cytotoxicity, oxidative stress, and inflammatory response. Based on multiomics, bioinformatics, and molecular biology, Rural SC-PM2.5 inhibits ribonucleotide reductase regulatory subunit M2 (RRM2) to disrupt the cell cycle, impede DNA replication, and ultimately inhibit lung cell proliferation. Furthermore, this study supplements and supports the epidemic investigation. Through an analysis of the transcriptome and human disease database, it is found that Rural SC-PM2.5 may mainly involve pulmonary hypertension, sarcoidosis, and interstitial lung diseases; in particular, congenital diseases may be ignored by epidemiological surveys in rural areas, including tracheoesophageal fistula, submucous cleft of the hard palate, and congenital hypoplasia of the lung. This study contributes to a greater scientific understanding of the health risks posed by rural PM2.5, elucidates the pathogenesis of respiratory diseases, clarifies the types of respiratory diseases, and promotes environmental equity.

Project description:As the climate changes due to global warming, the frequency of appearance of marine-derived toxins increases. In particular, the need to investigate marine-derived toxins for which toxicity has not yet been identified is emerging. Blood vessels are passageways through which compounds entering the body move to various organs and are the sites first exposed to compounds. Therefore, it is important to know the effects of compounds on blood vessels when they enter the body. In this study, the human vascular endothelial cell line EA.hy926 was exposed to the marine toxins OA (IC20; 42.9 nM) and the mechanism of toxicity was investigated at the transcriptome level. Quantseq 3' mRNA sequencing was performed by extracting RNA from EA.hy926 cells exposed to the toxins. Differentially expressed genes were determined based on fold change ≥ 1.5 and P value < 0.05.

Project description:Objectives: To explore the molecular mechanisms of PM2.5-induced dysfunction in human corneal epithelial cells (HCECs). Methods: RNA-Seq was performed to identify the differentially expressed genes (DEGs) in PM2.5-exposed HCECs compared to unexposed condition, which was followed by validation via real-time PCR (qRT-PCR). Results: A total of 434 DEGs—240 up-regulated and 194 down-regulated—were identified in PM2.5-exposed HCECs rather than unexposed HCECs. The expression of a few genes related to proliferation, inflammation, and aryl hydrocarbon stimulation were significantly altered by PM2.5 exposure, which may contribute to PM2.5-related corneal diseases. Conclusion: The present study identified the altered expression of hundreds of genes in HCECs exposed to PM2.5, which suggests the importance of PM2.5 for cornea health.
