Fig. 1From: Association of functional genetic variants in TFF1 and nephrolithiasis risk in a Chinese populationLuciferase activity affected by rs3761376. Different luciferase reporter vectors with either rs3761376 allele (G or A) which included the sequence of the promoter of TFF1 were transfected into HEK-293 cells. Then, the luciferase activity was detected and normalized by the internal control of Renilla luciferaseBack to article page
