本发明提供了一种hnRNP A2*蛋白质,编码该蛋白的核酸及用途。所述蛋白含有蛋白,蛋白质片段或蛋白质的类似物或衍生物的氨基酸序列如SEQ ID NO。1。本发明hnRNP A2*蛋白质能主动解开端粒G-四,结合最小结合位点,在3′端粒的尾端,露出五个核苷酸可配合端粒酶RNA模板和促进端粒延伸端粒酶的作用下,从而保持细胞的分裂潜能。
一种抗人PrPC蛋白的单克隆抗体,能够以靶向方式降低转录因子Twist1的表达水平,并诱导巨噬细胞和NK细胞靶向直肠癌肿瘤细胞。 抗体与西妥昔单抗联合用药的抑瘤效果也优于单用抗体或西妥昔单抗。
本发明涉及一种重组广谱绿僵菌及其在促进植物根系生长中的应用,属于农业生物技术领域。 本发明的重组广谱绿僵菌表达下调的单胺氧化酶或不表达单胺氧化酶,能够促进植物根的生长。
延缓衰老,制备恶性人骨髓间充质干细胞的方法可抗选择性。 制备方法, 第二密码子的253个氨基酸残基的FOXO3蛋白, 丝氨酸密码子编码丙氨酸突变的密码子,FOXO3蛋白密码子的第315位氨基酸残基,丝氨酸密码子编码丙氨酸突变的密码子编码2个突变中的一个突变,编码多能干细胞的基因组包括该步骤。 制备的重组间充质干细胞,并进一步提供其在移植治疗中的用途。 [附图]
中国科学院动物研究所专利:Recombinant Metarhizium acridum, preparation method therefor and use thereof。
2023年10月7日,Nature plants在线发表了南京农业大学李姗教授团队题为“Improving rice nitrogen-use efficiency by modulating a novel monouniquitination machinery for optimal root plasticity response to nitrogen”的研究论文。该团队在水稻中鉴定到一...
The flight of insects may look effortless but, as with any animal, their movements would be wildly uneven without an intricate system of neural signaling and muscle response to stabilize and steer the...
For the first time, researchers at MIT, Caltech, Harvard University, and elsewhere sent quantum information across a quantum system in what could be understood as traversing a wormhole. Though this ex...
With their stretched bodies, immense wingspan and iridescent coloring, dragonflies are a unique sight. But their originality doesn’t end with their looks: As one of the oldest insect species on the pl...
A new machine learning approach helps scientists understand why extreme precipitation days in the Midwest are becoming more frequent. It could also help scientists better predict how these and other e...
A new article gives an overview of almost three decades of research into colloidal quantum dots, assesses the technological progress for these nanometer-sized specs of semiconductor matter, and weighs...
Strategies to reduce antibiotic prescribing in primary care are insufficient alone to halt the rise in drug resistant E. coli infections in England, a new report concludes.
Researchers have found that a common plant owes the dazzling blue color of its fruit to fat in its cellular structure, the first time this type of color production has been observed in nature.The plan...
Plants take up much of the water that falls to Earth. They use what they need before releasing it through tiny holes on the surfaces of their leaves, just as people release water vapor every time they...
