Western analysis of primary BC comparing day 0 (Figure 6C, lane 1) and day 28 (Figure 6C, lane 2) demonstrated expression of the basal cell marker TP63 at both time points, with a reduction in levels at ALI Day 28, while Clara (CC10) and ciliated (DNAI1, FOXJ1) cell markers were only detected at ALI day 28 (Figure 6C). The gene discussed is DNAI1; the disease is breast cancer.
