BackgroundNumerous epidemiological studies have confirmed that diabetes can promote the development of malignant tumors. However, the relationship between renal cell carcinoma (RCC) and diabetic nephropathy (DN) is still controversial. This study aimed to investigate the genes that are co-expressed in DN and RCC in order to gain a better understanding of the relationship between these diseases, and to identify potential biomarkers and targets for the treatment of DN-related RCC.MethodsWe evaluated the differentially expressed genes (DEGs) that are co-expressed in DN and RCC using a wide range of target prediction and analysis methods. Twenty-four genes were identified by intersecting the differential genes of 3 DN datasets and 2 RCC datasets. We predicted the micro-ribonucleic acids (miRNAs) of these genes that may be controlled using the miRNA Data Integration Portal (mirDIP) database, and rated them according to each data forecast based on the Comparative Toxicogenomics Database (CTD) and the StarBase database.ResultsFour genes were associated with DN and RCC patients: the predicted miRNAs hsa-miR-200b-3p and hsa-miR-429 of fibronectin 1 (FN1); the predicted miRNA hsa-miR-29c-3p of collagen type 1 alpha 2 (COL1A2); the predicted miRNA hsa-miR-29c-3p of collagen type 3 alpha 1 (COL3A1); and the predicted miRNA hsa-miR-29a-3p and hsa-miR-200c-3p of glucose-6-phosphatase catalytic subunit (G6PC). These genes may serve as potential biomarkers or specific targets in the treatment of DN-related RCC.ConclusionsA significant correlation was identified between DN and RCC. The FN1, COL1A2, COL3A1, and G6PC genes could be novel biomarkers of DN-related RCC. 相似文献

Diabetic nephropathy (DN) is a chronic kidney disease caused by the long-term loss of renal function, which occurs in 20% - 40% of all diabetes and is also the primary cause of end-stage renal diseases. DN is related with other lethal diseases, particularly cardiovascular diseases, leading to an increased risk of death. Therefore, an effective treatment for DN is required. Here we tested the protective effect of dioscin in a mouse model of streptozocin (STZ)-induced DN. First, STZ was intraperitoneally injected into C57BL/6 J mice and TLR4-/- mice respectively, on a daily basis for 5 days to induce diabetes. Dioscin was then orally administered into diabetic mice daily for 8 weeks. Our results show that STZ injection effectively induced diabetes in mice as indicated by the increased blood glucose levels in C57BL/6 J mice, whereas it did not cause diabetes in TLR4-/- mice. Dioscin significantly ameliorated STZ-induced renal damage via reducing inflammatory responses in diabetic mice and antagonizing the activation of TLR4/NF-κB pathway and the production of inflammatory cytokines. In conclusion, our study highlights the potential of dioscin as a novel approach to treat DN in diabetic patients. 相似文献

Chronic graft-versus-host disease (cGVHD) is a major complication, affecting 50% to 80% of long-term survivors of allogeneic hematopoietic stem cell transplantation. Current cGVHD therapies are neither specific nor curative, and patients are typically maintained for several months to years under immunosuppressive regimens that are associated with important side effects and increased susceptibility to life-threatening infections. As a result, continued investigation into the pathology of the disease and the search for novel diagnostic and therapeutic strategies to treat cGVHD remains a high priority. We report that the cellular dynamics of various immune cell subsets are related to cGVHD onset and severity in a cohort of allogeneic hematopoietic stem cell transplantation recipients. We document a decrease in the proportion of CD45RO+ CD4?CD8? (double-negative [DN]) T cells at the onset of cGVHD, a time at which serum levels of B cell activating factor and B cells are increased. We also find that DN T cell levels are correlated with cGVHD severity. Our present findings are in line with the view that activated DN T cells exhibit their immunoregulatory potential by eliminating B cells in vivo. Taken together, these findings suggest that maintaining elevated DN T cell numbers before the onset of cGVHD may prevent pathological B cell responses. 相似文献

ABSTRACTThe Cochrane Library of Systematic Reviews is published quarterly as a DVD and monthly online (http://www.thecochranelibrary.com). The April 2013 issue (2nd DVD for 2013) contains 5484 complete reviews, 2341 protocols for reviews in production, and 22,600 short summaries of systematic reviews published in the general medical literature. In addition, there are citations of 692,000 randomized controlled trials, and 15,700 cited papers in the Cochrane methodology register. The health technology assessment database contains some 12,000 citations. Ninety-four new reviews have been published in the previous 3 months, of which four have potential relevance for practitioners in pain and palliative medicine. The impact factor of the Cochrane Library stands at 5.715. Readers are encouraged to access the full report for any articles of interest, as only a brief commentary is provided. 相似文献

Mixed connective tissue disease (MCTD) is a systemic autoimmune disorder, characterized by the presence of antibodies to U1-RNP protein. We aimed to determine phenotypic abnormalities of peripheral B cell subsets in MCTD. Blood samples were obtained from 46 MCTD patients, and 20 controls. Using anti-CD19, anti-CD27, anti-IgD and anti-CD38 monoclonal antibodies, the following B cell subsets were identified by flow cytometry: (1) transitional B cells (CD19 + CD27-IgD + CD38high); (2) naive B cells (CD19 + CD27-IgD + CD38low); (3) non-switched memory B cells (CD19 + CD27 + IgD+); (4) switched memory B cells (CD19 + CD27 + IgD-); (5) double negative (DN) memory B cells (CD19 + CD27-IgD-) and (6) plasma cells (CD19 + CD27highIgD-). The proportion of transitional B cells, naive B cells and DN B lymphocytes was higher in MCTD than in controls. The DN B cells were positive for CD95 surface marker. This memory B cells population showed a close correlation with disease activity. The number of plasma cells was also increased, and there was an association between the number of plasma cells and the anti-U1RNP levels. Cyclophosphamide, methotrexate, and corticosteroid treatment decreased the number of DN and CD27high B cells. In conclusion, several abnormalities were found in the peripheral B-cell subsets in MCTD, which reinforces the role of derailed humoral autoimmune processes in the pathogenesis. 相似文献
