CircBACH1 (hsa_circ_0061395) promotes hepatocellular carcinoma growth by regulating p27 repression via HuR

Bingqi Liu, Guangsheng Yang, Xin Wang, Jingfang Liu, more

Journal of Cellular Physiology > 235 > 10 > 6929 - 6941

In recent years, an increasing number of circular RNAs (circRNAs) have been discovered in hepatocellular carcinoma (HCC). However, the functions of most circRNAs require further investigation. Here, we found that circBACH1 was significantly upregulated in HCC tissues and that high circBACH1 levels were closely associated with poor prognosis. In addition, circBACH1 could promote HCC growth by accelerating...

Huangyue Cai, Xing Zhang, Li Hu, Fangwei Guo, more

International Journal of Applied Ceramic Technology > 17 > 5 > 2416 - 2423

The Raman peaks of metastable yttria‐stabilized zirconia changed with annealing at high temperatures even before the onset of transformation to any monoclinic phase, leading to ambiguous determination of stress‐free references. In this work, the evolution of the Raman bands of metastable YSZ with annealing for different times at different high temperatures were analyzed using the tetragonality variation,...

Iron‐Catalyzed [2+2+2] Annulation of Aliphatic Bridged 1,n‐Enynes with Aldehydes for the Synthesis of Fused Pyrans

Tian Tian, Xin Wang, Leiyang Lv, Zhiping Li

European Journal of Organic Chemistry > 2020 > 28 > 4425 - 4428

An iron‐catalyzed [2+2+2] annulation of aliphatic bridged 1,n‐enynes with aldehydes was developed. Aldehydes play a dual role as the precursors of acyl radicals to trigger the cascade cyclization but also as the radical acceptors to terminate the annulation. This two‐in‐one strategy overcomes the limitation in [2+2+m] cyclization that requires a rigid benzene skeleton as the essential linker, thus...

Pseudomonas syringae dual‐function protein Lon switches between virulence and metabolism by acting as both DNA‐binding transcriptional regulator and protease in different environments

Canfeng Hua, Tingting Wang, Xiaolong Shao, Yingpeng Xie, more

Environmental Microbiology > 22 > 7 > 2968 - 2988

Lon, a member of the AAA+ protease family, plays vital roles in Type III secretion systems (T3SS), agglutination and colony shape in the model plant pathogen Pseudomonas syringae. Lon also functions as a transcriptional regulator in other bacterial species such as Escherichia coli and Brevibacillus thermoruber. To reveal the molecular mechanisms of Lon as a dual‐function protein in P. syringae, we...

Fam70A binds Wnt5a to regulate meiosis and quality of mouse oocytes

Na‐Na Zhang, Teng Zhang, Wen‐Yi Gao, Xin Wang, more

Cell Proliferation > 53 > 6 > n/a - n/a

Objectives Little is known about the roles of integral membrane proteins beyond channels, carriers or receptors in meiotic oocytes. The transmembrane protein Fam70A was previously identified as a likely “female fertility factor” in Fox3a‐knockout mouse ovaries where almost all follicles underwent synchronous activation and the mice became infertile very early. However, whether Fam70A functions in...

Jian‐Xin Wang, Ye‐Guang Fang, Chun‐Xiang Li, Li‐Ya Niu, more

Angewandte Chemie > 132 > 25 > 10118 - 10122

An organic crystal of 4,4′‐bis(N‐carbazolyl)‐1,1′‐biphenyl (pCBP) exhibits time‐dependent afterglow color from blue to orange over 1 s. Both experimental and computational data confirm that the color evolution results from well‐separated, long‐persistent thermally activated delayed fluorescence (TADF) and room‐temperature phosphorescence (RTP) with different but comparable decay rates. TADF is enabled...
