Example sentences for: rtk
How can you use “rtk” in a sentence? Here are some example sentences to help you improve your vocabulary:
It is hypothesized that trans-tyrosine phosphorylation of the EGFR creates protein phosphotyrosine binding sites that act as a surrogate scaffold for ERK activation [ 7 ] . Since ORs share many similarities with LPAR and β 2 -ARs in the way they activate the ERK pathway [ 9 15 ] , we chose to examine whether RTK transactivation occurs and is a necessary aspect of δ-opioid-mediated ERK activation.
In this report, we have presented considerable evidence that δ-ORs and EGFRs activate ERKs, independently, without the need for transphosphorylation of a co-expressed RTK.
Despite the presence of these catalytic RTK inhibitors, δ-opioid-mediated ERK activation was not significantly altered in comparison to untreated cultures (Figure 9).
Determining whether a co-expressed RTK is structurally necessary for δ-OR-mediated ERK activation
The down-regulation is most apparent on cellular receptors that have intrinsic receptor tyrosine kinase (RTK) activity and signal transduction members that mediate RTK function; including the Ras-Raf-MEK pathway, and co-activators such as p300/CBP and SRC-1, which mediate gene expression related to hormone receptor genes.
