Project description:Several epidemiological pieces of evidence on air pollution health effects have notably accelerated in recent years. They have described the relationship between PM2.5 (ambient fine particulate matter of <2.5 μm in diameter) and kidney diseases. Previous research has shown that lactoferrin showed renoprotective effects against some kidney diseases. In the current study, we analyzed the transcriptional profiles of PM2.5 and lactoferrin using RNA sequencing (RNA-seq) and identified the key signaling pathway in the human kidney proximal tubular epithelial cell line (HK-2 cells).

Project description:Atmospheric fine particulate matter (PM2.5) causes severe haze in China and is regarded as a threat to human health. The health effects of PM2.5 vary location by location due to the variation in size distribution, chemical com position, and sources. In this study, the cytotoxicity effect, oxidative stress, and gene expression regulation of PM2.5 in Chengdu and Chongqing, two typical urban areas in southern China, were evaluated. Urban PM2.5 in summer and winter significantly inhibited cell viability and increased reactive oxygen species (ROS) levels in A549 cells. Notably, PM2.5 in winter exhibited higher cytotoxicity and ROS level than summer. Moreover, in this study, PM2.5 commonly induced cancer-related gene expression such as cell adhesion molecule 1(PECAM1), interleukin 24 (IL24), and cytochrome P450 (CYP1A1); meanwhile, PM2.5 commonly acted on cancer-related biological functions such as cell-substrate junction, cell-cell junction, and focal adhesion. In partic ular, PM2.5 in Chengdu in summer had the highest carcinogenic potential among PM2.5 at the two sites in summer and winter. Importantly, cancer-related genes were uniquely targeted by PM2.5, such as epithelial splicing regu latory protein 1 (ESRP1) and membrane-associated ring-CH-type finger 1 (1-Mar) by Chengdu summer PM2.5; collagen type IX alpha 3 chain (COL9A3) by Chengdu winter PM2.5; SH2 domain-containing 1B (SH2D1B) by Chongqing summer PM2.5; and interleukin 1 receptor-like 1 (IL1RL1) and zinc finger protein 42 (ZNF423) by Chongqing winter PM2.5. Meanwhile, important cancer-related biological functions were specially induced by PM2.5, such as cell cycle checkpoint by Chengdu summer PM2.5; macromolecule methylation by Chengdu win ter PM2.5; endoplasmic reticulum-Golgi intermediate compartment membrane by Chongqing summer PM2.5;and cellular lipid catabolic process by Chongqing winter PM2.5. Conclusively, in the typical urban areas of southern China, both summer and winter PM2.5 illustrated significant gene regulation effects. This study contrib utes to evaluating the adverse health effects of PM2.5 in southern China and providing public health suggestions for policymakers.

Project description:DON impaired the male spermatogenesis and induced oxidative stress, testicular apoptosis and disruption of blood-testis barrier (BTB). The milk protein lactoferrin (LF) is an iron-binding glycogenprotein with multifunctions including anti-inflammation and antioxidant. The current study was aimed to investigate the beneficial effects of LF on spermatogenesis and integray of BTB of mice treated with diet DON.

Project description:Yangyinqingfei Decoction (YYQFD), a traditional Chinese prescription, is well known in the treatment of diphtheria and lung-related diseases in clinic. However, the underlying mechanism how to treat lung-related diseases remains unclear. In the present study, the intervention effect of YYQFD on PM2.5-induced lung injury mice and its potential mechanism were investigated by metabolomics and proteomic techniques. The results showed that YYQFD could significantly improve pulmonary functions, relieve lung injury, as well as reduce IL-6, TNF-α and MDA, and increase SOD levels in serum and BALF of PM2.5-induced lung injury mice. Furthermore, the protein-metabolite joint analysis presented that YYQFD regulated the pathways of arachidonic acid metabolism, linoleic acid metabolism, and biosynthesis of unsaturated fatty acids with significantly down-regulating arachidonic acid, 20-HETE, prostaglandin E2, lecithin, linoleic acid, α-linolenic acid, eicosatetraenoic acid, and γ-linolenic acid, and up-regulating PTGES2, GPX2 and CBR3 protein expressions in lung tissue. A regulatory metabolic network map was further constructed, which provide us a better understanding about the role of YYQFD on PM2.5-induced lung injury mice and new insight into YYQFD application for the treatment of lung-related diseases.

Project description:Cisplatin is a potent chemotherapeutic drug, widely used in the treatment of various solid cancers. However, its clinical effectiveness is strongly limited by frequent severe adverse effects, such as nephrotoxicity and chemotherapy-induced peripheral neuropathy. Therefore, there is an urgent medical need to identify novel strategies that would limit cisplatin-induced toxicity. In the present study, we provide evidence that the FDA-approved adenosine A2A receptor antagonist istradefylline (KW6002) significantly protects from cisplatin-induced nephrotoxicity and neuropathic pain in experimental models of acute and sub-chronic cisplatin intoxication. Importantly, we also demonstrate that the anti-tumoral properties of cisplatin were not altered by istradefylline in tumor-bearing mice and even potentiated at the molecular level. Altogether, the present results support the use of istradefylline as a new valuable preventive approach for the clinical management of patients undergoing cisplatin treatment.
