1Long noncoding RNAs:a missing link in osteoporosis显示文摘Osteoporosis is a systemic disease that results in loss of bone density and increased fracture risk,particularly in the vertebrae and the hip.This condition and associated morbidity and mortality increase with population ageing.Long noncoding(lnc)RNAs are transcripts longer than 200 nucleotides that are not translated into proteins,but play important regulatory roles in transcriptional and post-transcriptional regulation.Their contribution to disease onset and development is increasingly recognized.Herein,we present an integrative revision on the studies that implicate lncRNAs in osteoporosis and that support their potential use as therapeutic tools.Firstly,current evidence on lncRNAs involvement in cellular and molecular mechanisms linked to osteoporosis and its major complication,fragility fractures,is reviewed.We analyze evidence of their roles in osteogenesis,osteoclastogenesis,and bone fracture healing events from human and animal model studies.Secondly,the potential of lncRNAs alterations at genetic and transcriptomic level are discussed as osteoporosis risk factors and as new circulating biomarkers for diagnosis.Finally,we conclude debating the possibilities,persisting difficulties,and future prospects of using lncRNAs in the treatment of osteoporosis.Andreia Machado Silva Sara Reis Moura JoseHenrique Teixeira Mario Adolfo Barbosa Susana Gomes Santos Maria Ines Almeida 2019Bone Research2019,7,1:13
2Helicobacter pylori and EBV in gastric carcinomas:Methylation status and microsatellite instability显示文摘AIM:To verify the methylation status of CDH1, DAPK, COX2, hMLH1 and CDKN2A genes and to evaluate their association with Helicobacter pylori (H. pylori)-cagA+ and Epstein Barr virus (EBV) infections in gastric adenocarcinomas.METHODS: Methylation-specific PCR (MSP) assay was performed in 89 primary gastric carcinomas (intestinal and diffuse types). Microsatellite instability (MSI) analysis was performed using the BAT26 primer set and PCR products were analyzed with the ABI PRISM 3100 Genetic Analyzer using Genescan 3.7 software (Applied Biosystems). Detection of H. pylori and genotyping were performed by PCR, using specifi c primers for ureaseC and cagA genes. The presence of EBV was assessed by in situ hybridization. Statistical analyses were performed using the χ2 or Fisher's exact test.RESULTS: The most frequent hypermethylated gene was COX-2 (63.5%) followed by DAPK (55.7%), CDH1 (51%), CDKN2A (36%) and hMLH1 (30.3%). Intestinal and diffuse adenocarcinomas showed different methylation profiles and there was an association between methylation of E-CDH1 and H. pylori-cagA+ in the intestinal adenocarcinoma type. MSI was correlated with hMLH1 methylation. There was an inverse correlation between DAPK hypermethylation and MSI.CONCLUSION: We found a strong association between CDH1 methylation and H. pylori-cagA+ in intestinal-type gastric cancer, association of MSI and better prognosis and an heterogeneous COX-2 overexpression.Adriana Camargo Ferrasi Nídia Alice Pinheiro Silvia Helena Barem Rabenhorst Otávia Luisa Caballero Maria Aparecida Marchesan Rodrigues Fabrício de Carvalho Celso Vieira de Souza Leite Marcia Valéria Pitombeira Ferreira Marcos Aurélio Pessoa Barros Maria Inês de Moura Campos Pardini 2010World Journal of Gastroenterology2010,16,3:6
