Project description:Controlling the progression of chronic kidney disease (CKD) at an early stage is critical for reducing disease severity. A cross-sectional study of chronic kidney disease (CKD) patients at all stages with S. stercoralis infection found that helminth infection caused gut dysbiosis, which may be involved in CKD progression. Because of the variation of gut microbiome results with helminth infection, the cross-sectional study of 16S rRNA sequencing, therefore, is insufficient to draw valid conclusions and correct the effects of S. stercoralis on the early stages of CKD. Combination with other omics approach is warrant to be better understand the disease.

Project description:Molecular changes underlying the failing heart in chronic kidney disease (CKD) remains largely undefined. To date, a severe paucity of translational studies investigating these changes utilizing human heart tissues from kidney failure patients exists. Moreover, no studies have examined alterations of the cardiac cytoskeleton in CKD, despite its central role in regulating organelle function, bioenergetics and myocardial remodeling. In this 3-arm cross-sectional controlled cohort study, we compared donor heart tissues from dialysis patients, to patients with hypertension with relatively preserved GFR, and healthy controls. We present evidence for transcriptomic changes in the hearts of dialysis patients, involving cytoskeletal dysregulation and dysfunction of mitochondrial bioenergetics.

Project description:Background: Hypertension is one of the most common metabolic diseases in the elderly and its pathogenesis is associated with microbiota dysbiosis. Recent evidence suggests that oral microbiota dysbiosis is also an important factor in the development of hypertension. However, the relationship between hypertension and oral flora in the elderly has not been adequately investigated. Objective: The aim of this cross-sectional study was to investigate the structure of the oral microbiota and its correlation with hypertension in elderly hypertensive patients. To provide new ideas for the prevention and treatment of hypertension. Methods: 206 subjects aged 60 ~ 89 years were selected and divided into normal (CON) and hypertensive (HTN) groups, according to the 2018 Chinese Guidelines for the Management of Hypertension. The oral microbiome composition of saliva samples was determined by 16S rRNA gene sequencing. Results: Although there was no significant difference in α and β diversity between the two groups, systolic and diastolic blood pressure were the most important factors influencing the structure of the oral microbiota. At the phylum level, the relative abundance of the spirochete phylum and the mutualistic bacterial phylum was higher in the HT group than in the CON group (p < 0.05). Diastolic blood pressure was negatively correlated with Streptococcus. Furthermore, we analyzed HTN patients with 120 mmHg<systolic blood pressure<160 mmHg and systolic blood pressure>160 mmHg separately and found that the abundance of Saccharibacteria_(TM7) was significantly increased in the HTN_2 group. Conclusions: Our study identified specific oral microbiota in elderly hypertensive patients, confirming the relationship between oral microbiota and hypertension. This enhances our understanding of the important role of oral microbiota in the pathogenesis of hypertension and accumulates more evidence for microbial involvement in the development of hypertension.

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:Development of a method to identify age-regulated expression trends in skeletql muscles and study the underlying molecular processes of the age_associated progressive changes in skeletal muscles. See abstract from associated manuscript below : Aging is characterized by progressive tissue degeneration and it is associated with genome-wide changes of mRNA expression profiles. Therefore, it is expected that age-regulated changes in expression profiles could describe the process of aging. We have developed a robust and unbiased methodology to identify age-regulated expression trends in cross-sectional data sets from healthy donors. Our analysis in four different tissues reveals that in brain cortex and Vastus lateralis muscles, two major age-associated expression inclinations were found, one during midlife and one in elderly. In kidney medulla and cortex, however, transcriptional changes were found only in elderly. In concurrence with increased degeneration in aged tissue, the elderly-associated expression changes are predominantly downwards. Our results suggest that a non-linear trend describes the aging process, and can be the result of inclinations of gene expression at two distinct age-positions affecting different molecular and cellular processes. RNA was extracted from vastus lateralis muscles. cDNA synthesis and labeling were preformed with the Illumina cDNA labeling kit.

Project description:These subjects were diagnosed as being controls or having interstitial lung disease (ILD) or chronic obstructive pulmonary disease (COPD) as determined by clinical history, CT scan, and surgical pathology. There was no intervention, these are cross-sectional data. All samples are from the Lung Tissue Research Consortium (LTRC) and are indexed by their LTRC tissue label.
