In conclusion, reduced activity of SPPL2a protease in monocytes from AS predisposes to endosomal accumulation of CD74 and CD74 N-terminal fragments, which, upon IFNγ-exposure, is deposited at the plasma membrane and can be recognized by anti-CD74/CLIP autoantibodies.

The prevalence is higher in certain geographic locations. Beginning in 2014, the Centers for Disease Control and Prevention's Division of Nutrition, Physical Activity, and Obesity awarded funding to 11 land-grant universities through the High Obesity Program. This program implemented evidence- and practice-based strategies with a goal to increase access to nutritious foods and places to be physically active in counties in which the prevalence of obesity among adults was more than 40%. In these counties, funded land-grant universities developed partnerships and collaborations to work with community organizations, public health agencies, and other stakeholders to promote policy and environmental changes that address obesity. Data were collected by the Cooperative Extension Service in each selected county with technical assistance from land-grand universities and the Centers for Disease Control and Prevention. More than 2 million people were reached by the nutrition and physical activity policy, systems, and environmental interventions implemented.OBJECTIVE The objective of this study is to evaluate racial/ethnic differences in disease manifestations and survival in a US cohort of patients with systemic sclerosis (SSc), with a focus on Asian patients. METHODS A retrospective cohort study was conducted among Kaiser Permanente Northern California adults with an incident SSc diagnosis by a rheumatologist from 2007 to 2016, confirmed by a chart review to fulfill 2013 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria. Self-reported race/ethnicity was categorized as non-Hispanic white, Asian, Hispanic, and black. Disease manifestations and survival were compared, using white patients as the reference. RESULTS A total of 609 patients with incident SSc were identified 89% were women, and 81% had limited cutaneous SSc, with a mean age at diagnosis of 55.4 ± 14.8 years. The racial/ethnic distribution was 51% non-Hispanic white (n = 310), 25% Hispanic (n = 154), 16% Asian (n = 96), and 8% black (n = 49). Com2020 The Authors.

It is the most common organic acidemia, manifested as methylmalonic academia combined with homocysteinemia. Early screening and diagnosis are important. The mutation spectrum of the MMACHC gene causing cblC varies among populations. The mutation spectrum in Chinese population is notably different from that in other populations. METHODS A PCR followed by high-resolution melting curve analysis (PCR-HRM) method covering all coding exons of MMACHC gene was designed to verify 14 pathogenic MMACHC gene variants found in patients with cblC, including all common mutations in Chinese patients with cblC. RESULT By PCR-HRM analysis, 14 pathogenic variants of MMACHC showed distinctly different melting curves, which were consistent with Sanger sequencing. The homozygous type of the most common mutation c.609G > A (p.Trp203Ter) can also be analyzed by specially designed PCR-HRM. CONCLUSION The established PCR-HRM method for screening common pathogenic MMACHC variants in Chinese patients with cblC has the advantages of high accuracy, high throughput, low cost, and high speed. It is suitable for the large-sample screening of suspected children with methylmalonic acidemia and carriers in population. © 2020 The Authors.

However, the mechanisms by which radon induces lung and other cancers, especially the radon-induced Warburg effect, have not been fully elucidated. The aim of this study was to investigate the role of the succinate dehydrogenase subunit A (SDHA)-mediated Warburg effect in (human bronchial epithelial) BEAS-2B cells with malignant transformations induced by long-term radon exposure. Soft agar colony formation and MMP-9 were increased following radon-induced malignant transformation. Additionally, we observed the Warburg effect in BEAS-2B cells following long-term radon exposure, evidenced by increases in the levels of glucose uptake, lactate, and lactate dehydrogenase (LDH). Following radon exposure, the expression of SDHA was decreased, while the levels of HIF-1α and hexokinase-2 (HK2) were increased. Our findings suggested that the SDHA-associated pathway may be involved in mediating the Warburg effect in radon-induced malignant transformation of BEAS-2B. © 2020 Wiley Periodicals, Inc.MiR-20a has been reported as a key regulator to pro-inflammatory factor release in fibroblast-like synoviocytes (FLS), which caused rheumatoid arthritis (RA). However, the molecular mechanism of miR-20a in RA remains to be further elucidated. This study aimed to investigate the roles of miR-20a in RA pathology. RA (n = 24) and osteoarthritis (OA, n = 20) and normal healthy tissues (n = 16) were collected from operation. TargetScan and dual-luciferase reporter were performed to predict and confirm the potential binding sites of miR-20a on ADAM metallopeptidase domain 10 (ADAM10). Pearson's analysis was adopted to evaluate the correlation between miR-20a and ADAM10 expression. It was found that MiR-20a was downregulated in RA tissues, and overexpressed miR-20a inhibited cell viability, migration and invasion, and the expression of inflammatory factors in RA-FLS MH7A cells. ADAM10 was identified as the target gene of miR-20a, and upregulation of ADAM10 reversed the inhibitory effects of miR-20a. In conclusion, miR-20a inhibits the progression of RA-FLS as well as the inflammatory factor expression by targeting ADAM10.
