WebSecond messenger modulate cellular activity in the nervous system: -Rapid turnover of 2nd messenger molecules – transient effects (secs) -Longer-term responses require covalent modification of proteins -Achieved by phosphorylation of target proteins by protein kinases -Effects reversed by dephosphorylation of target proteins by phosphatases. Web8 Dec 2010 · The level of gene expression for each sequence from both host and tumor cell populations are shown in table 1. MMP1 gene expression was detectable largely in the tumor cell population (p = 0.05). The range of difference in expression of MMP1 between tumor cells and stromal cells after normalization ranged from 4 -fold to a 100-fold …
