On the other hand, the differences in mRNA levels of Secretoglobin (SCGB3A1), a product of secretory cells, did not reach statistical significance between cells co-infected with the non-mucoid PA isolate and single HRV16 infection (0.18 ± 0.11 fold change vs. 0.32 ± 0.12 fold change, p=0.188) (Figure 5C). This evidence concerns the gene SCGB3A1 and infection.
