Expression of cytokeratin-7 and cytokeratin-19 on newborn mice induced rhesus rotavirus as biliary atresia model.

Introduction: biliary atresia (BA) is a progressive inflammation that causes obstruction and fibro-obliteration of the bile ducts during the perinatal period. Biliary atresia occurs in about 1 in 5000 to 8000 live births, and 50% require liver transplantation. This study aims to iinvestigate the influence of induction and duration of illness after rhesus rotavirus (RRV) exposure to changes in the expression of cytokeratin-7 (CK-7) and cytokeratin-19 (CK-19) in mice models of AB.

Methods: a total of 48 Balb/c less than a day after birth was included as model of BA. The overall sample was split randomly by using the randomization table into 4 control groups and 4 treatment groups. Groups 1,2,3, and 4 composed of 24 infant mice Balb/c (each group of 6 tails) with blue color code get a placebo (buffered saline) intraperitoneallyless than a day after birth. Groups 5, 6, 7, and 8 were composed of 24 mice Balb/c (eachgroup of 6 tails) with red color code get induction RRV 1.5 x 106 Plaque forming units (PFU) as treatment groups.

Results: there are influence of the RRV induced changes in the expression of CK-7 murine model of BA day 3, 7, 14 and 21 after induction compared to the control (p<0.05). There was interaction between induction effects and duration of illness after RRV exposure to CK-7 expression in murine models of BA on days 3, 7, 14 and 21 (p<0.001). There was difference in the value of CK-19 expressions progressively between trial group and control group seen from day-3 and day 21.

Conclusion: induction and duration of illness after rhesus rotavirus exposure effect on the expression of cytokeratin-7 and cytokeratin-19 mice models of biliary atresia.
