Uorescence and immunohistochemical staining of junctional systems revealed decreased expression of ZO-1 and an altered distribution of beta-catenin, respectively, in intestinal samples from DXR/5-FU-treated mice, whereas samples from mice that also received BLF501 at 25 g/kg showed the common honeycomb distribution of ZO-1 and expression/distribution of beta-catenin related to that in manage mice; the two.five g/kg BLF501 dose was much less efficient. BLF501 (25 g/kg) alone didn’t alter the expression or distribution of either ZO-1 or beta-catenin (Figure 5A-J). We then evaluated extracts of tiny intestine samples for the expression of ERM proteins, which play a crucialCardani et al.

Immunofluorescence assay for BrdU-positive proliferating cells was performed. DXR-induced lower of proliferation price apoptosis was observed in the three- to six-cell positions inside crypts. Good cells count was performed. (A) UNTR, untreated; (B) BLF501 25 g/kg; (C) DXR 48 h; (D) DXR 72 h; (E) DXR + BLF501 25 g/kg 48 h; (F) DXR + BLF501 25 g/kg 72 h.
