Background MIKC type MADS-box transcription factors are one of the largest gene families and play a pivotal role in flowering time and flower development. Chimonanthus salicifolius belongs to the family Calycanthaceae and has a unique flowering time and flowering morphology compared to other Chimonanthus species, but the research on MIKC type MADS-box gene family of C. salicifolius has not been reported. Objective Identification, comprehensive bioinformatic analysis, the expression pattern of MIKC-type MADS-box gene family from different tissues of C. salicifolius. Methods Genome-wide investigation and expression pattern under different tissues of the MIKC-type MADS-box gene family in C. salicifolius, and their phylogenetic relationships, evolutionary characteristics, gene structure, motif distribution, promoter cis-acting element were performed. Results A total of 29 MIKC-type MADS-box genes were identified from the whole genome sequencing. Interspecies synteny analysis revealed more significant collinearity between C. salicifolius and the magnoliids species compared to eudicots and monocots. MIKC-type MADS-box genes from the same subfamily share similar distribution patterns, gene structure, and expression patterns. Compared with Arabidopsis thaliana, Nymphaea colorata, and Chimonanthus praecox, the FLC genes were absent in C. salicifolius, while the AGL6 subfamily was expanded in C. salicifolius. The selectively expanded promoter (AGL6) and lack of repressor (FLC) genes may explain the earlier flowering in C. salicifolius. The loss of the AP3 homologous gene in C. salicifolius is probably the primary cause of the morphological distinction between C. salicifolius and C. praecox. The csAGL6a gene is specifically expressed in the flowering process and indicates the potential function of promoting flowering. Conclusion This study offers a genome-wide identification and expression profiling of the MIKC-types MADS-box genes in the C. salicifolius, and establishes the foundation for screening flowering development genes and understanding the potential function of the MIKC-types MADS-box genes in the C. salicifolius.

Gloeostereum incarnatum is an edible medicinal mushroom widely grown in China. Using the whole genome of G. incarnatum, simple sequence repeat (SSR) markers were developed and synthetic primers were designed to construct its first genetic linkage map. The 1,048.6 cm map is composed of 10 linkage groups and contains 183 SSR markers. In total, 112 genome assembly sequences were anchored, representing 16.43 Mb and covering 46.41% of the genome. Selfing populations were used for quantitative trait loci (QTL) targeting, and the composite interval mapping method was used to co-localize the mycelium growth rate (potato dextrose agar and sawdust), growth period, yield and fruiting body length, and width and thickness. The 14 QTLs of agronomic traits had LOD values of 3.20–6.51 and contribution rates of 2.22– 13.18%. No linkage relationship was found between the mycelium growth rate and the growth period, but a linkage relationship was observed among the length, width and thickness of the fruiting bodies. Using NCBI’s BLAST alignment, the genomic sequences corresponding to the QTL regions were compared, and a TPR-like protein candidate gene was selected. Using whole-genome data, 138 candidate genes were found in four sequence fragments of two SSR markers located in the same scaffold. The genetic map and QTLs established in this study will aid in developing selective markers for agronomic traits and identifying corresponding genes, thereby providing a scientific basis for the further gene mapping of quantitative traits and the marker-assisted selection of functional genes in G. incarnatum breeding programs.

Fang Shen,Wan-li Huang,Bao-ping Xing,Xiang Fang,Mei Feng,Chun-ming Jiang 대한신경정신의학회 2018 PSYCHIATRY INVESTIGATION Vol.15 No.10

Objective: Recent studies have indicated the possibility that genistein may improve depression via regulating the expression of miR-221/222. This study is to explore whether genistein could improve depression by altering miR-221/222 levels and investigate the possible mechanisms involved in the improvement effect of genistein. Methods: The animal model of depression was established through unpredictable chronic mild stress. Nest building test and splash test were adapted to evaluate the effects of genistein on depressive symptoms in mice. qRT-PCR and western blot analysis were used to detect the expression of miR-221/222 and connexin 43 (Cx43) in the prefrontal cortex of the mice. In vitro, U87-MG astrocytes were treated with genistein and the expression of miR-221/222 and Cx43 was measured. The dual-luciferase reporter assay was used to verify whether Cx43 was a direct target of miR-221/222. Results: The behavioral tests showed that genistein could significantly reduce depression symptoms of mice, and this remission was not affected by gender. Genistein in vivo and in vitro could reduce increased levels of miR-221 and miR-222 in the prefrontal cortex of depressed mice, while upregulate Cx43 expression. Dual-luciferase reporter assay suggested Cx43 was directly regulated by miR-221/222 in astrocytes. Conclusion: Genistein can play its antidepressant effect through down-regulating miR-221/222 by targeting Cx43.

Jiang, Chang,Liao, Fang-Xin,Rong, Yu-Ming,Yang, Qiong,Yin, Chen-Xi,He, Wen-Zhuo,Cai, Xiu-Yu,Guo, Gui-Fang,Qiu, Hui-Juan,Chen, Xu-Xian,Zhang, Bei,Xia, Liang-Ping Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.13

Objective: To compare the efficacy of taxane-based regimens in the first line setting retrospectively in Chinese patients with recurrent and/or metastatic esophageal cancer. Methods: We analyzed 102 recurrent and/or metastatic esophageal cancer patients who received taxanes-based regimens in a first-line setting from January 2009 to December 2013. Sixteen (15.7%) patients were administered Nab-PTX based chemotherapy and 86 patients (84.3%) received paclitaxel (PTX) or docetaxel (DTX) based chemotherapy. Patients in the PTX/DTX group could be further divided into TP (71 patients) and TPF (15 patients) groups. Results: The objective response rate (ORR) of all patients was 20.6%, and the disease control rate (DCR) was 67.6%. The median overall survival (OS) was 10.5 months (95% CI 10.1-16.4) and the median progression-free survival (PFS) was 6.04 months (95% CI 5.09-7.91). The DCR was higher in the TPF group than the TP group (93.3% vs. 59.1%; p = 0.015 ). There were no significant differences in ORR, OS, and PFS among Nab-PTX, TPF and TP groups. Conclusions: The three regimens of Nab-PTX based, TP and TPF proved active in a first line setting of Chinese patients with recurrent and/or metastatic esophageal cancer, and should thus be regarded as alternative treatments.

This paper reveals the Chinese experience and narrative attitude embodied in the 19th-century actress Kim No-sang (金老商, 1787~?). Except for the introduction and conclusion, the study was divided into three chapters. The contents of each chapter are summarized as follows. In Chapter 2, I examined the composition of the work focusing on the artist's hard-historic tendencies and journeys. By combining various researcher's arguments, he confirmed that Kim No-Sang was Kim Ji-soo, a close character of the hardened tribe, and half-party status at the time of meandering. The journey is divided into domestic and foreign journeys. In the case of domestic journeys, they focused mainly on historical facts. Since then, he has shown the process of acquiring new knowledge through the reality of China on the journey of China. Entering the destination, Yeongyeong, they are immersed in the cultural splendor of Yeongyeong and show a detailed description. On the way back, the old struggles were expressed, expressing joy and longing for the family. Finally, I could see that I was doing my own duty. In Chapter 3, I reviewed the author's experiences of Hwanhee, Changhee, Balingood and Yurachang. Previously, Yonhee's concept was “to enjoy.” Therefore, the word yeonhee can be seen as enjoyable. In addition, 幻術, 幻戱 means ‘to change’, and it means to change into different shapes, properties, and characteristics. Chang-hee also says that the reason why the artist stopped watching was because of a language that does not work. The detailed description of the Qing Dynasty ‘valingood’ was sufficient to reveal cultural differences. The author also narrated the core source of Qing dynasty culture, namely the daily life and extraordinary life of glass windows. In the last chapter, we will examine the narrative attitude of <March Books>. The narrative attitude is divided into positive narratives of cultural differences, critical narratives of foreign characters and customs, objective narratives of history, and in-depth reporter narratives. First of all, the positive description of cultural differences will examine Qing's developed economy, emperor and Asian. Next, critical descriptions of foreign characters and customs will be divided into foreign characters and customs. He also studied objective and in-depth reporting on history. By examining the contents of the 19th-century love song Lyrics of the Unauthorized, it shows the freedom of self-resulting in it, showing that its literary charm is fully shown. Above all, I think the record is shining in that it has the effect of delivering information and interest to people who have never been to Yeongyeong.

Study on the role of gga-miRNA-200a in regulating cell differentiation and proliferation of chicken breast muscle by targeting Grb2

Keren Jiang,Fengbin Yan,Meng Zhang,Fang Li,Donghua Li,Guirong Sun,Xiaojun Liu,Hong Li,Ruili Han,Ruirui Jiang,Zhuanjian Li,Xiangtao Kang 한국통합생물학회 2017 Animal cells and systems Vol.21 No.6

Growth factor receptor-bound protein 2 (Grb2) have been proved by a lot of studies playing a major role in cell proliferation and cell differentiation. However, the regulation of Grb2 expression by microRNAs (miRNAs) in chicken breast muscle still remains unknown. The expression profile of Grb2 was checked based on our previous RNA sequencing data and the Grb2 relative expression level in breast muscle of aged hens (55-week-old) was validated significantly higher than juvenile hens (20-week-old) using qRT-PCR. miRNAs that interact with Grb2 have been predicted in chicken and the relationship between the potential miRNA and Grb2 was verified using dual luciferase reporter assay in chicken DF1 cells. Dual-luciferase reporter assays results demonstrated that the expression of luciferase reporter gene linked with part sequence of the 3′UTR of chicken Grb2 gene was down-regulated by the overexpression of gga (Gallus Gallus)- miR-200a-3p in the DF1 cells, and the down-regulation behavior was abolished when the ggamiR- 200a-3p binding site in 3′UTR of Grb2 was mutated, indicating that gga-miR-200a can suppress the expression level of its target gene Grb2. Therefore, we concluded that the significantly increased expression level of Grb2 in the breast muscle of aged chicken can (at least partly can) be explained by the decreased expression of miR-200a, which reduced the inhibitory effect on Grb2. Taken together, these findings suggest that gga-miR-200a can suppress the expression level of its target gene Grb2 and might be involved in the cell differentiation and proliferation of chicken breast muscle through binding with the 3’UTR of Grb2.

Push-out tests on demountable high-strength friction-grip bolt shear connectors in steel–precast UHPC composite beams for accelerated bridge construction

Haibo Jiang,Haozhen Fang,Jinpeng Wu,Zhuangcheng Fang,Shu Fang,Gongfa Chen 국제구조공학회 2022 Steel and Composite Structures, An International J Vol.45 No.6

Steel–precast ultra-high-performance concrete (UHPC) composite beams with demountable high-strength frictiongrip bolt (HSFGB) shear connectors can be used for accelerated bridge construction (ABC) and achieve excellent structural performance, which is expected to be dismantled and recycled at the end of the service life. However, no investigation focuses on the demountability and reusability of such composite beams, as well as the installation difficulties during construction. To address this issue, this study conducted twelve push-out tests to investigate the effects of assembly condition, bolt grade, bolt– hole clearance, infilling grout and pretension on the crack pattern, failure mode, load–slip/uplift relationship, and the structural performance in terms of ultimate shear strength, friction resistance, shear stiffness and slip capacity. The experimental results demonstrated that the presented composite beams exhibited favorable demountability and reusability, in which no significant reduction in strength (less than 3%) and stiffness (less than 5%), but a slight improvement in ductility was observed for the reassembled specimens. Employing oversized preformed holes could ease the fabrication and installation process, yet led to a considerable degradation in both strength and stiffness. With filling the oversized holes with grout, an effective enhancement of the strength and stiffness can be achieved, while causing a difficulty in the demounting of shear connectors. On the basis of the experimental results, more accurate formulations, which considered the effect of bolt–hole clearance, were proposed to predict the shear strength as well as the load–slip relationship of HSFGBs in steel–precast UHPC composite beams.
