The polyadenylation code: a unified model for the regulation of mRNA alternative polyadenylation 总被引：3，自引：2，他引：1
The majority of eukaryotic genes produce multiple mRNA isoforms with distinct 3′ ends through a process called mRNA alternative polyadenylation (APA). Recent studies have demonstrated that APA is dynamically regulated during development and in response to environmental stimuli. A number of mechanisms have been described for APA regulation. In this review, we attempt to integrate all the known mechanisms into a unified model. This model not only explains most of previous results, but also provides testable predictions that will improve our understanding of the mechanistic details of APA regulation. Finally, we briefly discuss the known and putative functions of APA regulation. 相似文献

Library instruction videos can enhance student instruction. At a community college, librarian-created videos provided students with academic support. However, the videos were rarely used. In this article, students were sent online surveys to rate videos discussing the American Psychological Association (APA) format. Students were also asked why they did not use the videos. Participants rated several video features, including length, technical aspects, narration, and style. While they overwhelmingly responded that the videos were useful, the students did not know where they were located. The major complaint was related to the videos' technical aspects. Students also reported that they were more inclined to ask for help after watching the video. 相似文献

美国心理学会(APA)在其出版手册中提出了语言变革,期望这一变革能对人们的思想产生影响.本文从词汇、语法和认知三个角度探讨了语言和思维的关系,肯定了Whorf假设中弱势版本的合理性,即:语言对思维的影响在于影响人们获得某种思维方式的难易程度. 相似文献

An acoustic pressure amplifier （APA） is capable of improving the match between a thermoacoustic engine and a load by elevating pressure ratio and acoustic power output. A standing-wave thermoacoustic engine driving a resistance- and-compliance （RC） load through an APA was simulated with linear thermoacoustics to study the impact of load impedance on the performance of the thermoacoustic system. Based on the simulation results, analysis focuses on the distribution of pressure amplitude and velocity amplitude in APA with an RC load of diverse acoustic resistances and compliance impedances. Variation of operating parameters, including pressure ratio, acoustic power, hot end temperature of stack, etc., versus impedance of the RC load is presented and analyzed according to the abovementioned distribution. A verifying experiment has been performed, which indicates that the simulation can roughly predict the system operation in the fundamental-frequency mode. 相似文献

Some key questions for publishers in today’s market are: Could Amazon’s recent merger and acquisitions strategy create a disruptive or paradigm shifting business model in the publishing industry? Do their recent actions post mergers and acquisitions illustrate a predicable pattern of behaviour that publishers can strategize around? This paper will explore these questions and look at some of the possible reasons behind Amazon’s business practices and the possible consequences to publishers. 相似文献
