Subsequently, Oproduced may increase KIF1Bβ protein expression in a positive feedback mechanism. Therefore, ROS and, specifically O, may be critical regulators of KIF1Bβ-mediated apoptosis and its protein expression in neuroblastoma.doi:10.1038/s41598-017-17192-6Clara Angelina...
From the essence of the stock market, it has a very useful function - achieving a positive cycle. If more and more excellent companies go public in the stock market and these companies are in a long-term upward channel, they can expand their Operation through financing from the stock market...
Taken together, our findings reveal a positive feedback–based mechanism that ensures proper assembly of the functional inner centromere during mitosis. They further suggest a causal link between centromeric cohesion defects and chromosomal instability in cancer cells....
In Arabidopsis, NCED3 is regulated by a positive feedback mechanism by ABA. In this study in peanut (Arachis hypogaea), we demonstrate that ABA biosynthesis is also controlled by negative feedback regulation, mediated by the inhibitory effect on AhNCED1 transcription of a protein complex between...
Interestingly, c-JUN induced FAM83A expression by directly binding to its promoter region and thus forming a positive-feedback loop for FAM83A/PI3K/AKT/c-JUN. In conclusion, we demonstrated that FAM83A, as a cancer-metastasis promoter, accelerates migration, invasion and metastasis by ...
In a metabolic pathway, a typical control mechanism is: a. positive feedback b. negative feedback c. neutral feedback Feedback Loop: A feedback loop is any type of loop in which the end product will exert some type of effect on earlier step of ...
其中的 ξ∼0.01M⊙−1 为每太阳恒星质量对应的超新星数目(其与恒星的初始质量函数相关), ε 为超新星能量转换为动能的效率。其中的 ESNe∼1051erg 为单个超新星的典型质量。当 Eeje=E 时,可以得到, MgasM∗=0.4ε(c10)−1(Vvir200km/s)−2 对于一个银河系尺度的暗晕,即使超新星能量全部可以...
Thus, intensified trade and interaction, and the flowering of specialist crafts, in a complex process of positive feedback, led to much more complex societies based on palaces, which were the economic hubs of a new Minoan civilization. [#paragraph3]Renfrew’s model made some assumptions that ...
the natural language processing pipeline.We then used a six items long survey to test the perception of feedback. We conducted an ordinary least squares analysis to model these items as dependent variables, which showed that highly informative feedback had positive effects on helpfulness and ...
[30,31]. Alquezar et al. (2008) found that the altered carotenoid composition in Cara Cara may conduct to a positive feedback regulatory mechanism of carotenoid biosynthesis during fruit development and maturation; and not only carotenogenic genes but also the isoprenoid genes were altered ...
