We used a reporter construct incorporating multimeric Lef/Tcf promoter sequences upstream of a luciferase reporter (TOPFLASH) and a control construct containing mutated promoter sequences (FOPFLASH, ref. 21). We cotransfected TOPFLASH or FOPFLASH, ?-catenin, and human wild-type Tcf-4 wild-type expression constructs into 293 cells. Optimized luciferase assays showed a basal level of TOP/FOP activity of between 4:1 and 20:1. Forty-eight hours after transfection, serum-starved 293 cells were treated with IGF-1 or insulin for 3 or 6 h. These factors alone failed to alter basal reporter activity (Fig. 6 b). A 16-h pretreatment of the transfectants with LiCl had a dramatic effect on reporter activity, with significant enhancement at 50 mM LiCl (P < 0.01 by Tukey's test for comparison with activity in the absence of LiCl). We saw a further increase in reporter activity when we added 50 ng/ml (6.5 nM) IGF-1 to transfectants pretreated with LiCl at 10 mM (P < 0.01 after 6 h of IGF-1 treatment) and at 50 mM (P < 0.01 after 3 h of IGF-1 treatment and P < 0.001 after 6 h)."; prov:wasQuotedFrom pubmed:11035789 . sub:_6 rdfs:label "Selventa" . sub:assertion prov:hadPrimarySource pubmed:11035789; prov:wasDerivedFrom beldoc:, sub:_5 . } sub:pubinfo { this: dct:created "2014-07-03T14:31:37.632+02:00"^^xsd:dateTime; pav:createdBy orcid:0000-0001-6818-334X, orcid:0000-0002-1267-0234 . }
