MUC5AC and colon dysplasia: Treatment with low dose [2.5 mg/kg] free 5FU did not show any significant preservation of mucin content (Figure 8C), whereas, the high dose [5 mg/kg] free 5FU treated groups (Figure 8D) as well as both low and high doses 5FU-PLNs-treated ones (Figure 8E,F) revealed improved goblet cell population compared to the colon dysplasia group and 2.5 mg/kg of free 5FU treated group.
