Figure Lengend Snippet: KI reduces the viability of SLC5A5-expressing SGC cells. ( A , B ) The fold change in SLC5A5 expression was determined by qPCR in ( A ) human submandibular SG epidermoid carcinoma (A253; n = 5), myeloid hematopoietic (HL-6; n = 2, U937; n = 2), human, and murine endothelial, respectively (HUVEC; n = 2, BMEC1; n = 3), as well as in (HT1080; n = 3) fibrosarcoma cells and ( B ) murine lymphoblast (32D; n = 2) cells, fibroblasts (MS-5; n = 2, 3T3; n = 2), and submandibular SG adenocarcinoma (WR21; n = 3) cells. SLC5A5 gene expression levels were normalized to BETA-ACTIN expression in the same samples, and fold changes were adjusted relative to the expression levels in control samples. ( C , D ) The iodine concentration was assessed in cell lysates of A253 ( C ) and WR21 ( D ) cells 48 h after KI treatment at the indicated concentrations ( n = 4/5 per group). ( E ) Representative light microscopy images of murine WR21 and human A253 SGC cells 48 h after incubation with or without KI (100 μM; scale bar = 100 μm). ( F ) The viability rate of A253 cells treated with the indicated KI concentrations for 48 h was determined by trypan blue exclusion ( n = 8 for the control (co) group and n = 3 for KI 25, 50, 100, and 200 μM groups). ( G , H ) The absolute number of viable and control (co) A253 ( G ) and WR21 cells ( H ) after 48 h in culture, following the addition of KI (100 μM), was determined using the trypan blue exclusion assay ( n = 10 and 5/group for A253 cells and n = 4, 3/group for WR21 cells). * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 using a one-way ANOVA test (to determine the effects of two independent variables on a dependent variable) or Student’s t -test (to compare the performance of two groups under different conditions), with mean ± SD depicted.
