Among these 5 miRNAs, miR-20a and miR-20b were validated as regulatory miRNAs in hypoxia-induced VEGF expression, whereas the other three could be expressed for the regulation of other genes without over-repressing VEGF expression due to competitive action.
Host cell engineering should take into account the nature of protein to be expressed for designing improved platforms for over-expression.
The L4 expression of these genes suggests they may be expressed for use in the adult cuticle, and, consistent with this, reduction of function for several of the genes leads to phenotypes suggestive of defects in cuticle function or integrity.
It is expected that while some genes will be up-regulated throughout diapause, others will be expressed for only a short period of time, including genes limited to expression during the early stages of induction, later once diapause is due to terminate, or even in a cyclically dependent fashion.
In hESC-derived erythroblasts where both ε and γ globin were active and marked by similar chromatin modifications, ε globin was immediately silenced upon transfer, whereas γ globin continued to be expressed for months, implying that different transcriptional environments were required for their continuing expression.
The expression P c (e|γ1) denotes the conditional bit error rate and can be expressed, for a binary phase-shift keying (BPSK) modulation, as P c ( e | γ 1 ) = Q 2 γ 1. (26).
After establishing our minicircle DNA expression vector, we tested whether AR protein delivered via minicircle DNA could be expressed for an extended period of time.
"An investigation will be done, mea culpas will be expressed for lack of institutional oversight, and a few scholarships will be lost.
