| 1 | Reactivation of γ-globin expression through Cas9 or base editor to treat β-hemoglobinopathies显示文摘Dear Editor,Mutations in the β-globin gene,the essential component of adult hemoglobin(HbA;a2p2),results in either a production of aberrant sickle hemoglobin(HbS)leading to sickle cell disease(SCD)or an insufficient β-globin synthesis leading to β-thalassemia.These two major forms of β-hemoglobinopathies cause impaired erythropoiesis and life-threatening anemia.Clinical evidence has suggested that reaaivation of fetal γ-globin(HBG)gene expression which is normally silenced after birth by certain genetic mutations can ameliorate the clinical course of β-hemoglobinopathies. | Liren Wang Linxi Li Yanlin Ma Handan Hu Qi Li Yang Yang Wenbang Liu Shuming Yin Wei Li Bin Fu Ryo Kurita Yukio Nakamura Mingyao Liu Yongrong Lai Dali Li | 2020 | Cell Research2020，30，3： | 14 |

| 3 | High mass loading Ni_(4)Co_(1)-OH@CuO core-shell nanowire arrays obtained by electrochemical reconstruction for alkaline energy storage显示文摘The design of three-dimensional(30)core-shell hetercistructures is an efficient method to achieve high mass specific capacity of electroactive materials under high mass loading.In this work,porous Ni_(4)Co1-0H nanosheets with a mass loading of 7.7 mg·cm^(-2) are obtained by using Ni_(4)Cor(NO_(3))_(2)(0H)_(4) supported on the CuO nanowires as precursors via an unavoidable electrochemically induced phase reconstruction.During the electrochemical reconstruction process,the N03-anions in Ni_(4)Cor(N0_(3))_(2)(0H)_(4) are easily replaced by OH-anions in the electrolyte.The phase reconstruction is accompanied by the decrease of ionic diffusion.:resistance and the increase of pore volume,and the shift of binding energy.The obtained Ni4Co1-0H nanosheets show a high:mass specific capacity of 363.6 mAh·g^(-1) at 5 mA·cm^(-2).The as-fabricated alkaline hybrid supercapacitor and Ni-Zn battery deliver high energy density of 293.1 and 604.9 Wh·kg^(-1),respectively,indicating.excellent alkaline energy storage performance. | Yawei Yu Xiulan Hu Shuai Wang Handan Qiao Zeyu Liu Kefan Song Xiaodong Shen | 2022 | Nano Research2022，15，1： | 1 |
| 4 | Herb-partitioned moxibustion regulated the miRNA expression profile in the thyroid tissues of rats with experimental autoimmune thyroiditis显示文摘OBJECTIVE:To observe the effect of herb-partitioned moxibustion(HPM)on the miRNA expression profile of thyroid tissue in experimental autoimmune thyroiditis(EAT)rats.METHODS:Rats were randomly divided into normal control(NC)group,EAT model(EAT)group,HPM group and western medicine(Med)group.EAT model rats were prepared by a combined immunization with complete and incomplete Freund’s adjuvant emulsified with porcine thyroglobulin and iodine.Rats in the HPM group were treated with HPM,while rats in the Med group were treated with levothyrocine(1μg/2 m L)by gavage.HE staining was used to observe the pathological morphological changes of thyroid tissue,ELISAs was uaed to detect the serum concentrations of TGAb,TPOAb,FT3,FT4,TSH.We then performed high-throughput mi RNA sequencing to analyse the mi RNA expression profiles in the thyroid tissues,followed by a bioinformatics analysis.RT-q PCR was used to verify the identified differentially expressed mi RNAs.RESULTS:HPM improved the thyroid tissue morphology and reduced serum TPOAb,TGAb,TSH concentration in EAT rats(P<0.05),but with no obvious effect on FT3 and FT4 concentration.While the TSH,FT3 and FT4 concentration was significantly changed in the Med group(P<0.01 or P<0.05)compared with that of EAT group.Sequencing results showed that a total of 17 mi RNAs were upregulated,and 4 were downregulated in the EAT rats,in which the expression levels of mi R-346 and mi R-331-5 p were reversed by HPM.The target genes of the mi RNAs that regulated by HPM wereassociated with a variety of immune factors and immune signals.RT-q PCR verification showed that the expression of mi RNA-346 and mi RNA-331-5 p was consistent with the sequencing results.CONCLUSIONS:HPM could regulate the the expression of mi RNA-346 and mi RNA-331-5 p,then act on their target genes to immune and inflammation-related pathways,which may be one of the mechanisms of HPM on EAT rats. | WANG Zhaoqin CUI Yunhua HUANG Yan WU Huangan ZHAO Jimeng HE Jinsen LIU Huirong ZHENG Handan WU Luyi HU Zhihai LIU Yanan | 2021 | Journal of Traditional Chinese Medicine2021，41，5： | 1 |
| 5 | Long-term amelioration of an early-onset familial atrial fibrillation model with AAV-mediated in vivo gene therapy显示文摘Atrial fibrillation(AF)is a common cardiac disease with high prevalence in the general population.Despite a mild manifestation at the onset stage,it causes serious consequences,including sudden death,when the disease progresses to the late stage.Most available treatments of AF focus on symptom management or alleviation,due to a lack of fundamental knowledge and the fact that considerable variations of AF exist.With the popularisation of the next-generation sequencing technology,several causal genetic factors,including MYL4,have been discovered to contribute to AF,giving hope to developing its gene therapies.In this study,we attempted to treat a previously established rat AF model,which carried Myl4E11K/E11K loss of function mutation,via overexpression of exogenous wild-type Myl4 by AAV9 vectors.Our results showed that delivery of Myl4 expressing AAV9 to postnatal rat models rescued the symptoms of AF,indicating the therapeutic potential that early gene therapy intervention can achieve long-term effects in treating cardiac arrhythmias caused by gene mutations. | Handan Hu Liren Wang Huiying Li Hailing Li Xi Chen Wenhui Peng Jun Wang Yongxiang Zhao Mingyao Liu Dali Li | 2022 | Fundamental Research2022，2，6： | 0 |
