Implementation of novel boolean logic gates for IMPLICATION and XOR functions using riboregulators

Chaoxin Chen, Qi Wu, Qingying Ke, Ting Wang, Yifan Zhang, Feiwen Wei, Xiaolong Wang & Guanglei Liu
To date, several different types of synthetic genetic switches, including riboregulators, riboswitches, and toehold switches, have been developed to construct AND, OR, NOT, NAND, NOR, and NOT IMPLICATION (NIMP) gates. The logic gate can integrate multiple input signals following a set of algorithms and generate a response only if strictly defined conditions are met. However, there are still some logic gates that have not been implemented but are necessary to build complex genetic circuits. Here,...

Design, synthesis and nematocidal activity of novel 1,2,4-oxadiazole derivatives with a 1,3,4-thiadiazole amide moiety

Dan Liu, Zhengxing Wang, Jing-Jiang Zhou & Xiuhai Gan
A series of novel 1,2,4-oxadiazole derivatives containing 1,3,4-thiadiazole amide group was synthesized and their nematocidal activities were evaluated. The results indicated that compounds 4-methoxy-N-(5-(((3-(p-tolyl)-1,2,4-oxadiazol-5-yl)methyl)thio)-1,3,4-thiadiazol-2-yl)benzamide 4i and N-(5-(((3-(4-chlorophenyl)-1,2,4-oxadiazol-5-yl)methyl)thio)-1,3,4-thiadiazol-2-yl)benzamilde 4p showed good nematocidal activity against Bursaphelenchus xylophilus. The corrected mortality of compounds 4i and 4p at 200 mg/L was 57.1% and 60.1%, respectively, which are much better than 13.5% of the commercial seed coating agent Tioxazafen. Compounds 4i and 4p dramatically decreased the head swinging, body fluctuation,...

Controlled synthesis of cube-like ZnSnO3 decorated by nickel-based films and electrochemical applications on lithium-sulfur batteries

Mianjiao Jiang, Jun Wu, Hongmei Guo, Hongfang Zhang, Manli Zhu & Xiaobang Xu
Transition metal oxide was considered as an effective cathode additive to depress ‘shuttle effect’ in lithium-sulfur (Li-S) batteries via forming a strong polar chemical bond with polysulfides. Here, we firstly synthesized unique S@Ni/NiO/ZnSnO3 microcubes as composite cathodes for Li-S batteries, in which Ni/NiO films were deposited onto surface of as-prepared ZnSnO3 microcubes via a hydrothermal reaction and later calcinations process. The S@Ni/NiO/ZnSnO3 composite showed attractive electrochemical performances with a high initial discharge-specific capacity of 1070...

A novel genetic variant potentially altering the expression of MANBA in the cerebellum associated with attention deficit hyperactivity disorder in Han Chinese children

Xinzhen Chen, Ting Yao, Jinliang Cai, Qi Zhang, Shanyawen Li, Huiru Li, Xihang Fu & Jing Wu
To obtain additional insight into the genetic factors of attention deficit hyperactivity disorder (ADHD). First, we performed a transcriptome-wide association study (TWAS) integrating human cerebellum-specific variant-expression/splicing correlations to identify ADHD susceptibility genes. Then, the associations between expression/splicing quantitative trait loci (eQTLs/sQTLs) of the transcriptome-wide significant genes and ADHD were observed in a case-control study of Han Chinese children. Furthermore, dual luciferase reporter gene assays were performed to validate the regulatory function of ADHD risk variants....

Human umbilical cord mesenchymal stem cells contribute to the reconstruction of bladder function after acute spinal cord injury via p38 mitogen-activated protein kinase/nuclear factor-kappa B pathway

Jue Li, Jiliang Huang, Ling Chen, Wei Ren & Wenzhi Cai
The association between spinal cord injury (SCI) and bladder symptoms has been intensively described. Human umbilical cord mesenchymal stem cell (hUC-MSC) treatment is beneficial to the recovery of bladder function after SCI, but its mechanism is unclear. We established an SCI model, and prepared hUC-MSCs in advance, followed by verification using flow cytometry. The Basso, Beattie and Bresnahan (BBB) score and urodynamic index were employed to evaluate motor function and bladder functions, respectively. Hematoxylin–eosin staining,...

Long non-coding RNA terminal differentiation-induced non-coding RNA regulates cisplatin resistance of choroidal melanoma by positively modulating extracellular signal-regulated kinase 2 via sponging microRNA-19b-3p

Wei Li, Aiqin Nie, Longyu Jin, Yubo Cui, Ning Xie & Gaohua Liang
In the present study, we aimed to investigate the role of long non-coding RNA terminal differentiation-induced non-coding RNA (TINCR) in cisplatin (DDP) resistance of choroidal melanoma (CM) and the potential molecular mechanisms. CM and non-CM tissues were collected from 60 CM patients. DDP-resistant CM cells were obtained by selection with linearly increased DDP treatment. The expression levels of TINCR, microR-19b-3p (miR-19b-3p), and extracellular signal-regulated kinase 2 (ERK-2) were detected by quantitative real-time PCR. Cholecystokinin octapeptide...

Two new abietane diterpenoids, phlecarinatone A (1) and phlecarinatone B (2), along with two known analogues (3 and 4), were isolated from Phlegmariurus carinatus. The structures of 1 − 4 were unambiguously elucidated by comprehensive spectroscopic analyses. Abietane diterpenoids were isolated from the plant for the first time. All isolates were tested for their neuroprotective activities against H2O2-induced SH-SY5Y cells injury, and compound 2 showed moderate effect at the concentrations ranging from 5 ∼ 20...

Safe, efficacious, and deployable vaccines are urgently needed to control COVID-19 in the large-scale vaccination campaigns. We report here the preclinical studies of an approved protein subunit vaccine against COVID-19, ZF2001, which contains tandem-repeat dimeric receptor-binding domain (RBD) protein with alum-based adjuvant. We assessed vaccine immunogenicity and efficacy in both mice and non-human primates (NHPs). ZF2001 induced high levels of RBD-binding and SARS-CoV-2 neutralizing antibody in both mice and non-human primates, and elicited balanced TH1/TH2...

Atg1-mediated Atg11 phosphorylation is required for selective autophagy by regulating its association with receptor proteins

Weijing Yao, Yixing Li, Yingcong Chen, Yuting Chen, Yu Xie, Miaojuan Ye, Ying Zhang, Xiangjun Chen, Xiaoyong Wu, Yuyao Feng, Zhi Hong, Yigang Wang, Wei Liu & Cong Yi
Atg11 is an adaptor protein required for the induction of selective autophagy via receptor binding. However, our understanding of the molecular mechanisms by which it regulates selective autophagy remains incomplete. Here, we show that Atg11 is phosphorylated by Atg1. Rapamycin treatment or starvation conditions induced slower electrophoretic mobility of Atg11 in an Atg1 kinase activity-dependent manner. Through in vitro kinase assays combined with mutagenesis, we determined that Atg1 phosphorylates S949, S1057, and S1064 residues in...

Stachydrine is effective and selective against blast phase chronic myeloid leukaemia through inhibition of multiple receptor tyrosine kinases

Ruixin Gu, Wei Zhang & Dandan Xu
Resistance to BCR-ABL tyrosine kinase inhibitor (TKI) is the cause of treatment failure in blast phase chronic myeloid leukaemia (BP-CML). Agents that act synergistically with BCR-ABL TKI are required to improve response. This work investigated the effects of stachydrine in CML. CML cells were treated with control or stachydrine at 20, 40 and 80 µM. Proliferation and apoptosis were examined after 72 h treatment. Combination studies were performed in four groups: control, TKI, stachydrine and...

Tengcheng Que, Jing Li, Yugan He, Panyu Chen, Wei Lin, Meihong He, Lei Yu, Aiqiong Wu, Luohao Tan, Yingjiao Li, Yanling Hu & Yigang Tong
Pangolins have gained increasing global attention owing to their public health significance as potential zoonotic hosts since the identification of SARS-CoV-2-related viruses in them. Moreover, these animals could carry other respiratory viruses. In this study, we investigated the virome composition of 16 pangolins that died in 2018 with symptoms of pneumonia using metagenomic approaches. A total of eight whole virus sequences belonging to the Paramyxoviridae or Pneumoviridae families were identified, including one human parainfluenza virus...

Bit1 is involved in regulation between integrin and TGFβ signaling in lens epithelial cells

Bo Ma, Ni Ni, Wanyu Shao, Jingying Xu, Jiali Ji & Min Luo
Bit1, as an integrin-specific effector, is specifically expressed in lens epithelial cells (LECs) and may be essential to maintain the normal function of LECs. The present study investigated the function of Bit1 and its regulatory mechanism in LECs. Knockdown of Bit1 was mediated by a lentivirus with a specific short-hairpin RNA against Bit1 in SRA01/04 cells. Cell proliferation ability was measured by CCK-8 assay. Cell migration was examined by transwell and wound-healing assays. The effect...
