The phrase "activities are mediated" is correct and usable in written English.
It can be used in contexts discussing how activities are facilitated or influenced by external factors or agents.
Example: "In this study, we explore how social interactions indicate that activities are mediated by cultural norms."
Alternatives: "activities are facilitated" or "activities are influenced".
The precise mechanism by which TGF-β regulates angiogenesis remains the subject of much debate, however, it is generally accepted that TGF-β can have both pro- and anti-angiogenic activities and that these activities are mediated by differential activation of the ALK5-SMAD2/3 ALK1-SMAD1/5/8 ALK1-SMAD1/5/8nsignalon patransduction
Its activities are mediated by caspase-dependent and cytochrome-c-mediated apoptosis in RCC cells.
These activities are mediated primarily through the mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3-kinase (PI3K -Akt PI3K -Akt[ 38].
Moreover, in human umbilical vein endothelial cells, canstatin inhibits the phosphorylation of Akt and focal adhesion kinase, induces Fas ligand expression, and activates caspase-dependent apoptotic pathways [ 54]; all these activities are mediated by interaction with αv β3 and αv β5 integrins on the surface of endothelial cells [ 55].
These proteolytic activities are mediated predominantly by a family of proteases termed matrix metalloproteinases (MMPs).
This constitutes a difference with the host cells, in which these activities are mediated by thioredoxins.
The antitumor activities were mediated by a decrease of stat 3, bcl-2, and survivin, as well as an increase in caspase-3 shown in Fig. 7b.
Protection of chromosome ends from DNA repair and degradation activities is mediated by specialized protein complexes bound to telomere repeats.
Cardiac effects of adrenergic activity are mediated mainly by β1-receptors, although β2- and α-adrenoceptors are also involved.
It is likely that the caMEKK1-induced increases in NF-κB and RAR activity are mediated by hyperactivation of p300.
This suggests that the effects on Cdk2 activity are mediated by the hyperactivation of the checkpoint induced by Plx1 deficiency.
