| 3 | Association between the nasopharyngeal microbiome and metabolome in patients with COVID-19显示文摘SARS-CoV-2,the causative agent for COVID-19,infect human mainly via respiratory tract,which is heavily inhabited by local microbiota.However,the interaction between SARS-CoV-2 and nasopharyngeal microbiota,and the association with metabolome has not been well characterized.Here,metabolomic analysis of blood,urine,and nasopharyngeal swabs from a group of COVID-19 and non-COVID-19 patients,and metagenomic analysis of pharyngeal samples were used to identify the key features of COVID-19.Results showed lactic acid,L-proline,and chlorogenic acid methyl ester(CME)were significantly reduced in the sera of COVID-19 patients compared with non-COVID-19 ones.Nasopharyngeal commensal bacteria including Gemella morbillorum,Gemella haemolysans and Leptotrichia hofstadii were notably depleted in the pharynges of COVID-19 patients,while Prevotella histicola,Streptococcus sanguinis,and Veillonella dispar were relatively increased.The abundance of G.haemolysans and L.hofstadii were significantly positively associated with serum CME,which might be an anti-SARS-CoV-2 bacterial metabolite.This study provides important information to explore the linkage between nasopharyngeal microbiota and disease susceptibility.The findings were based on a very limited number of patients enrolled in this study;a larger size of cohort will be appreciated for further investigation. | Jing Liu Sheng Liu Zhao Zhang Xuejun Lee Wenxuan Wu Zhanlian Huang Ziying Lei Wenxiong Xu Dabiao Chen Xing Wu Yang Guo Liang Peng Bingliang Lin Yutian Chong Xiangyu Mou Mang Shi Ping Lan Tao Chen Wenjing Zhao Zhiliang Gao | 2021 | Synthetic and Systems Biotechnology2021，6，3： | 0 |
| 4 | Hsa-miR-637 inhibits human hepatocyte proliferation by targeting Med1-interacting proteins显示文摘Background:Recent studies have shown that mediator complex subunit 1(Med1)can significantly affect hepatocyte proliferation and differentiation.Acting as a tumor suppressor,microRNA-637(hsa-miR-637)can inhibit the growth of hepatocarcinoma cells and further induce cell apoptosis.However,the function of hsa-miR-637 and its target genes during liver regeneration remains to be elucidated.Methods:This study used co-immunoprecipitation(Co-IP)assay,transfection,luciferase reporter assay,functional assay by cell counting kit-8(CCK-8),Annexin V-FITC/propidium iodide apoptosis assay,and quantitative polymerase chain reaction analysis of chromatin immunoprecipitation(ChIP)for analysis.Results:Hsa-miR-637 has been suggested to suppress the expression of two Med1-interacting nuclear receptors,identified as the peroxisome proliferator-activated receptor alpha(PPARA)and thyroid hormone receptor alpha(THRA)at the transcriptional and translational levels in the human liver HL-7702 cell line.The interaction between Med1 and PPARA/THRA in HL-7702 cells was then confirmed.The transcriptional repression of hsa-miR-637 on PPARA and THRA was also demonstrated.Moreover,hsamiR-637 has been determined to suppress the proliferation of HL-7702 cells.Furthermore,cell cycle arrest of HL-7702 cells was induced by transfection of hsa-miR-637 at the S phase,but its apoptosis failed.Finally,PPARA was indicated to directly bind to the promoter of some transcription factors,like bcatenin,mouse double minute 2(MDM2),and p53.Conclusions:This study has confirmed that hsa-miR-637 plays an antiproliferative role during liver regeneration,which may contribute in understanding the regenerative process of the liver. | Jing Liu Jianyun Zhu Xiaohong Zhang Yuzhi Jia Xuejun Lee Zhiliang Gao | 2021 | Liver Research2021，5，2： | 0 |
