Table of qPCR quantitation of metallothionein and zinc transporter gene expression in SFM ARPE19 cultures (SS) and Zn-supplemented SFM ARPE19 cultures (Zn). RQ=relative quantity. All values are relative to the Day0 serum supplemented value. Bar chart shows the gene expression values of the metallothionein genes and the zinc transporter SLC39A1 during SFM culture and Zn-supplemented SFM culture. The gray bars represent the Day0 calibrator value. Orange bars represent the sample ratio to day 0; bars extending above the gray bars indicate increased expression, bars ending below the gray bars indicate decreased expression.
