Transcription factor OsWRKY11 induces rice heading at low concentrations but inhibits rice heading at high concentrations.

The heading date of rice is a crucial agronomic characteristic that influences its adaptability to different regions and its productivity potential. Despite the involvement of WRKY transcription factors in various biological processes related to development, the precise mechanisms through which these transcription factors regulate the heading date in rice have not been well elucidated. The present study identified OsWRKY11 as a WRKY transcription factor which exhibits a pivotal function in the regulation of the heading date in rice through a comprehensive screening of a clustered regularly interspaced palindromic repeats (CRISPR) ‒ CRISPR-associated nuclease 9 mutant library that specifically targets the WRKY genes in rice.

Construction and characterization of a humanized rat model with its application in evaluating the uptake of different statins.

Organic anion-transporting polypeptides 1B1 (OATP1B1) plays a crucial role in the transport of statins. However, there are too few animal models related to OATP1B1, especially humanized animal models. In this study, the human cDNA was inserted into the second exon of the rat gene using CRISPR/Cas9 technology.

Effect of Ce doping on the structure-activity relationship of MoVO composite metal oxides.

A series of Ce-doped MoVO composite metal oxide catalysts were prepared by the rotary evaporation method. The effects of Ce doping ratio on the crystal phase composition, morphology and surface properties of the catalysts were investigated. The results show that the crystal phase composition of samples with different Ce doping content is also obviously different.

Facile sub-/supercritical water synthesis of nanoflake MoVTeNbO -mixed metal oxides without post-heat treatment and their catalytic performance.

A fast and simple sub-/supercritical water synthesis method is presented in this work in which MoVTeNbO -mixed metal oxides with various phase compositions and morphologies could be synthesized without post-heat treatment. It was demonstrated that the system temperature for synthesis had a significant influence on the physico-chemical properties of MoVTeNbO . Higher temperatures were beneficial for the formation of a mixed crystalline phase containing TeVO, TeMoVO, MoO and TeO, which are very different from the crystalline phases of conventional Mo-V-Te-Nb-mixed metal oxides.

TPX2 in malignantly transformed human bronchial epithelial cells by anti-benzo[a]pyrene-7,8-diol-9,10-epoxide.

In order to elucidate the function of the targeting protein for Xenopus kinesin-like protein 2 (Xklp2) (TPX2) in the malignant transformation of human bronchial epithelial cells induced by anti-benzo[a]pyrene-trans-7, 8-dihydrodiol-9, 10-epoxide (anti-BPDE), TPX2 was characterized in cells at both the gene and the protein levels. TPX2 was present at higher levels in 16HBE-C cells than in 16HBE cells as demonstrated by two-dimensional gel electrophoresis, immunocytochemistry, Western blot analysis and RT-PCR. TPX2 was also detected in lung squamous-cell carcinoma tissues by immunohistochemistry, but not in normal lung tissues.
