| 1 | Exosomes with low miR-34c-3p expression promote invasion and migration of non-small cell lung cancer by upregulating integrinα2β1显示文摘Exosomes play critical roles in regulating various physiological and pathological processes,including immune stimulation,immune suppression,cardiovascular diseases,and cancers.Recent studies show that exosomes that transport specific microRNAs(miRNAs)are involved in tumor development.However,the molecular mechanism by which tumor invasion and migration are regulated by exosomes from non-small cell lung cancer(NSCLC)is not well understood.Here,we show that exosomes shuttling low levels of miR-34c-3p are involved in NSCLC progression.Our results showed that exosomes derived from NSCLC cells carrying low levels of miR-34c-3p could be transported into the cytoplasm of NSCLC cells and accelerate NSCLC invasion and migration by upregulating integrinα2β1.A luciferase assay revealed that integrinα2β1 was the direct target of miR-34c-3p,and overexpression of integrinα2β1 could promote the invasion and migration of NSCLC cells.The analysis of exosomes derived from clinical serum samples indicated that the expression of miR-34c-3p was significantly downregulated in exosomes from NSCLC patients compared with that of normal controls.A549-derived exosomes promoted NSCLC cells lung metastases in vivo.Exosomes shuttling low levels of miR-34c-3p were associated with the progression of NSCLC in vitro and in vivo.Our data demonstrate that exosomes shuttling low levels of miR-34c-3p can accelerate the invasion and migration of NSCLC by upregulating integrinα2β1.MiR-34c-3p can be a diagnostic and prognostic marker for NSCLC.High expression of integrinα2β1 is positively related to the migration and metastasis of NSCLC cells. | Wenjing Huang Yanyan Yan Yun Liu Minting Lin Jinxiang Ma Wei Zhang Jianwei Dai Jiajun Li Qiaoru Guo Hubiao Chen Bolat Makabel Hong Liu Chaoyue Su Hong Bi Jianye Zhang | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 5 |
| 2 | Clinical characteristics and post-discharge follow-up analyses of 10 infants with congenital tuberculosis:A retrospective observational study显示文摘Importance Congenital tuberculosis(TB)is a rare,potentially fatal disease.There is currently a lack of detailed clinical information available regarding this disease.Objective This retrospective study investigated the clinical manifestations,treatment,and long-term prognosis of congenital TB.Methods Patients were treated in Beijing Children’s Hospital,Capital Medical University(Beijing,China)between 2009 and 2018.Their demographic data,maternal and family histories,symptoms and signs,treatment information,and follow-up data were retrospectively collected using the hospital’s electronic information system.Results Ten infants with congenital TB were enrolled.The mean gestational age was 36.6±2.2 weeks and mean birth weight was 2517±487 g.All 10 patients exhibited fever,nine patients(90%)had anemia,and six patients(60%)had extrauterine growth retardation.On chest computed tomography scans,all 10 patients presented multiple pulmonary nodules and four patients(40%)had mediastinal adenopathy.Nine out of ten(90%)completed the T-spot test,and eight of them(8/9,89%)were positive.Anti-TB treatment was initiated upon diagnostic confirmation.All patients(100%)received combined treatment with isoniazid(INH)and rifampicin(RIF).Eight of 10 patients(80%)received combined treatment with INH,RIF,and pyrazinamide.The survival rate was 100%.One patient was lost to follow-up and four patients are currently continuing treatment.Three of nine patients(33%)achieved normal developmental milestones at 6 months of age.Interpretation Early diagnosis based on maternal history,typical imaging results,and timely treatment can improve outcomes in infants with congenital TB. | Juan Du Shixiao Dong Shengnan Jia Qiaoru Zhang Mingyan Hei | 2021 | Pediatric Investigation2021，5，2： | 4 |
| 3 | Hypoxia signaling in human health and diseases:implications and prospects for therapeutics显示文摘Molecular oxygen(O2)is essential for most biological reactions in mammalian cells.When the intracellular oxygen content decreases,it is called hypoxia.The process of hypoxia is linked to several biological processes,including pathogenic microbe infection,metabolic adaptation,cancer,acute and chronic diseases,and other stress responses.The mechanism underlying cells respond to oxygen changes to mediate subsequent signal response is the central question during hypoxia.Hypoxia-inducible factors(HIFs)sense hypoxia to regulate the expressions of a series of downstream genes expression,which participate in multiple processes including cell metabolism,cell growth/death,cell proliferation,glycolysis,immune response,microbe infection,tumorigenesis,and metastasis.Importantly,hypoxia signaling also interacts with other cellular pathways,such as phosphoinositide 3-kinase(PI3K)-mammalian target of rapamycin(mTOR)signaling,nuclear factor kappa-B(NF-κB)pathway,extracellular signal-regulated kinases(ERK)signaling,and endoplasmic reticulum(ER)stress.This paper systematically reviews the mechanisms of hypoxia signaling activation,the control of HIF signaling,and the function of HIF signaling in human health and diseases.In addition,the therapeutic targets involved in HIF signaling to balance health and diseases are summarized and highlighted,which would provide novel strategies for the design and development of therapeutic drugs. | Zhen Luo Mingfu Tian Ge Yang Qiaoru Tan Yubing Chen Geng Li Qiwei Zhang Yongkui Li Pin Wan Jianguo Wu | 2022 | Signal Transduction and Targeted Therapy2022，7，8： | 1 |
| 4 | The Physalis floridana genome provides insights into the biochemical and morphological evolution of Physalis fruits显示文摘The fruits of Physalis(Solanaceae)have a unique structure,a lantern-like fruiting calyx known as inflated calyx syndrome(ICS)or the Chinese lantern,and are rich in steroid-related compounds.However,the genetic variations underlying the origin of these characteristic traits and diversity in Physalis remain largely unknown.Here,we present a high-quality chromosome-level reference genome assembly of Physalis floridana(~1.40Gb in size)with a contig N50 of~4.87Mb.Through evolutionary genomics and experimental approaches,we found that the loss of the SEP-like MADS-box gene MBP21 subclade is likely a key mutation that,together with the previously revealed mutation affecting floral MPF2 expression,might have contributed to the origination of ICS in Physaleae,suggesting that the origination of a morphological novelty may have resulted from an evolutionary scenario in which one mutation compensated for another deleterious mutation.Moreover,the significant expansion of squalene epoxidase genes is potentially associated with the natural variation of steroid-related compounds in Physalis fruits.The results reveal the importance of gene gains(duplication)and/or subsequent losses as genetic bases of the evolution of distinct fruit traits,and the data serve as a valuable resource for the evolutionary genetics and breeding of solanaceous crops. | Jiangjie Lu Meifang Luo Li Wang Kunpeng Li Yongyi Yu Weifei Yang Pichang Gong Huihui Gao Qiaoru Li Jing Zhao Lanfeng Wu Mingshu Zhang Xueyang Liu Xuemei Zhang Xian Zhang Jieyu Kang Tongyuan Yu Zhimin Li Yuannian Jiao Huizhong Wang Chaoying He | 2021 | Horticulture Research2021，8，1： | 0 |
