Additionally, these approaches analyzed the relation between chromatin and splicing, looking at one single condition at the time, rather than comparing two conditions, and exons were classified as constitutive or alternative based on RNA data from one single condition, rather than distinguishing those that are regulated from the non-regulated ones between two conditions.
"In my country, the Internet is regulated from the top down".
Scientists from Duke University and eight other institutions have attempted to shed light on this question of how an ecosystem is regulated, from the top down (by predators) or bottom up (by plants).
The objective of this review is to survey the current understanding of the means by which fluid flow in bone is regulated, from the level of the skeletal system down to the level of osteocyte, and to provide impetus for future research in this area of signal transduction and coupling.
Arguments are provided suggesting that, although the ability to characterise and manipulate the yeast genome is necessary, this must be backed up by an intimate knowledge of processes at the cellular level and the ways in which these are regulated from the genome through transcription to the metabolome.
If the weapons had been regulated from the beginning, this all might well have been avoided.
In particular, the establishment of a trade monopoly by the magister militum (general) John Tzibus, which was regulated from the newly constructed fortress of Petra, drove Gubazes to seek once again the protection of the Persian shah, Khosrau I (r. 531 579).
A mammalian expression construct in which the subcloned C. saccharolyticum bglA gene is regulated from the human elongation factor 1α (EF1α) promoter was generated to create pEF bglA.
The application of our new method enables the identification of 31 miRNA/target-gene pairs that were expected to have been regulated from the era of the common bilaterian ancestor.
However, in our work, VEGF was overexpressed through constitutive retroviral vectors in transduced myoblast populations, which were previously shown to generate tissue levels of VEGF several fold higher than the maximum induced by ischemia (von Degenfeld et al, 2006), whereas Sema3A was not overexpressed and was regulated from the endogenous promoter.
