Chemotherapy and radiation are often accompanied by complications such as intestinal mucositis. The aim of this study was to assess by immunohistochemical assay the consequences of epirubicin-based therapy applied to onco-hematological patients, on the mucosal cells that undergo apoptosis and on the tight junction proteins, immediately before and after a short time of chemotherapy administration. We assessed the protein expression and distribution of the pro-apoptotic Bax, anti-apoptotic Bcl-2 and effector Caspase-3 as key proteins in apoptosis pathways and the changes in immunopositivity of Claudin-1 and ZO-1 tight junction proteins. Results show that the Bcl-2 family is involved in intestinal damage via Caspase-3 dependent apoptosis of epithelial cells. Additionally, the intestinal mucositis activates other injurious pathways through a dramatic drop in Claudin-1 and ZO-1 expressions, contributing for a while to a structural and functional integrity disruption of the intestinal epithelium.

Background Intestinal and hepatic manifestations of lupus seem to be underestimated in comparison to other major organ lesions. Although recent data point to gut-liver axis involvement in lupus, gut permeability dysfunction and liver inflammation need to be more investigated. Objective This study aims to assess fecal calprotectin, intestinal tight junction proteins and liver inflammation pathway in wild-type murine imiquimod- induced lupus. Methods C57BL/6 mice were topically treated on their right ears with 1.25 mg of 5% imiquimod cream, three times per week for six weeks. Fecal calprotectin was collected at day 0, 22 and 45. Renal, liver and intestinal pathology, as well as inflammatory markers, intestinal tight junction proteins, and E. coli protein in liver were assessed at sacrifice. Results At six weeks, lupus nephritis was confirmed on histopathology and NGAL and KIM-1 expression. Calprotectin rise started at day 22 and persists at day 45. Protein expression of Claudine, ZO-1 and occludin was significantly decreased. E. coli protein was significantly increased in liver with necro-inflammation and increased TLR4, TLR7, and pNFκB/NFκB liver expression. Conclusion This study is the first to demonstrate early fecal calprotectin increase and liver activation of TLR4- NFκB pathway in wild-type murine imiquimod-induced lupus.
