Among the seven genes, an obvious upregulation of IFT88 (Figure 8A) in breast cancer was found whereas INTU (Figure 8B), WDR19 (Figure 8C), WDR35 (Figure 8D) and CDON (Figure 8F) expression levels in breast cancer samples were significantly lower than that in normal breast samples. The gene discussed is IFT88; the disease is breast carcinoma.
