Compared to the most potent activating point mutation in FGFR3, K650E, this increase is less pronounced (kcat/Km comparison) (Fig. 4A, Supplemental Table S2).
However, studies have shown that DMF also inhibits NF-κB [ 27, 47], one of the most potent activating transcription factors of pro-inflammatory genes.
Our data demonstrated that Clerodendrum polysaccharide sub-fraction CSP-AU1, which was one of the most potent activators of cytokine production, activated PBMCs and monocyte/macrophages via TLR4 and signaling cascades involving Akt2/3, GSK-3α/β, p38β, p38δ, p38γ, p70S6K1, RSK2, mTOR, and AP-1/NK-κB.
Our results demonstrate that DDT and dichlorodiphenyldichloroethane (DDD) were the most potent activators of AP-1 activity; 2,2-bis p-chlorophenyl) acetic acid failed to activate.
Simply, the machinery that is activated during apoptosis (caspase activation) also acts through the BCL10/MALT1/CARMA pathway to activate NF κB, which is the most potent activator of HIV transcription, via the HIV LTR.
In certain cell types, K-Ras is the most potent activator of Raf-1 [ 40, 41], whereas H-Ras most efficiently activates PI3K [ 40].
For instance, while all ErbB receptors activate the MAPK pathway via Shc and/or Grb2, ErbB3 is the most potent activator of PI3K signalling due to its multiple binding sites for the p85 regulatory subunit of PI3K [ 7, 8].
Compound 11c showed the most potent activity.
As the most potent cells activating and polarizing naive T cells, oral dendritic cells (DCs) are of major importance in induction of immunity and tolerance.
With respect to the ability of rTFs to activate the expression of FLO11, cells carrying rTFs with a DBD of 3F 3ZfFLO11/F2 (and an AD of either VP16 or VP64) appeared to be the most potent in activating expression of FLO11, resulting in a significantly altered phenotype.
In murine model, it is generally accepted that Th1 type response is needed for control and protection against Leishmania infections, and interferon gamma (IFN-γ) secreted by Th1 cells, is the most potent macrophage-activating cytokine leading to host resistance to infection with Leishmania parasites [21].
