Electrophoretic mobility shift assays (EMSA) and ChIP assays demonstrated that both Sp1 and Sp3 bind to these elements and the binding activity is enhanced in senescent cells.
Others have shown that USF binding activity is enhanced in response to LPS [ 56].
In this context, many studies have shown that overall MEF2 DNA-binding activity is enhanced in cardiomyocytes in response to biomechanical and neurohormonal stimuli[11], [12], [13].
Aldosterone activated cAMP-response element-binding protein (CREB), and this activation was enhanced by blocking ICaT or by inhibiting protein phosphatase 2A (PP2activityity.
Compared with the IL-1β untreated control, ESE-1 loading onto the corresponding promoters was significantly enhanced after IL-1β stimulation, indicating that ESE-1 bound to the three predicted binding sites of GP73 promoter, and this binding activity was strongly enhanced by IL-1β treatment.
When cytosolic extracts from LD-infected and uninfected macrophages were incubated with P-labelled IRE-containing transcript, an RNA binding activity was observed, which was strongly enhanced in cytosolic extracts isolated from LD-infected spleen-derived macrophages (Fig. 5A).
In addition, biological activity assays of such glycoengineered mAbs showed that their antigen binding activity was not altered but significantly enhanced antibody-dependent cell-mediated cytotoxicity (ADCC) effect [ 70, 71].
However, the TIP150-binding activity was greatly enhanced when the C-terminal coiled-coil domain of MCAK was present (Fig 3D, lane 21).
Nuclear p65 DNA-binding activity was also enhanced by TRAIL (fourfold at 1 h), which was again reduced by BMS-345541.
FOXO DNA binding activity is reduced by acetylation and enhanced by deactylation [ 36, 37, 42, 43].
