These genetic information in mice and individuals suggest that very long phrase publicity to large lev els of IFN may be needed for IFN to minimize the sever ity of TSC associated kidney condition. In our prior preclinical analyze using Tsc2 mice, single agent IFN was administered for 10 months and there was considerable reduction in the sever ity of kidney disorder. We have beforehand in comparison the mixture of CCI 779 plus IFN with single agent CCI 779 and solitary agent IFN in nude mice bearing Tsc2 tumors and located a considerable reduction in tumor growth and improved survival with combination therapy. In contrast, in this article we evaluated combination CCI 779 plus IFN making use of Tsc2 mice and observed no profit to including the IFN to CCI 779 in this study. After thinking of the specifics of these relevant prior scientific studies, we conclude that this discrepancy is probably due to the shorter IFN address ment length compared with our prior study utilizing Tsc2 mice, alongside with insufficient power to detect a insignificant variance among the teams.
A comparison of our prior scientific tests utilizing nude mice bearing TSC relevant tumors also indicates that early cure with IFN yields a better response. In Lee et al, 2005 we treated animals on day eighteen following Tsc2 cells had been injected and tumors ended up tiny and we noticed a spectacular enhancement with IFN cure. In Lee et al, 2006, the research style dif fered as IFN treatment method was initiated when subcutaneous tumors ended up appreciably bigger, and while solitary agent IFN was however fairly successful, the reaction was subtle. In the Tsc2 analyze documented listed here, we observed that the mixture remedy cohort had a lower cystadenoma score than the one agent CCI 779 cohort in each the 6 8 month and 10 12 thirty day period groups, while this variation was not statistically considerable. It is feasible that early and extended IFN remedy alongside with more substantial cohorts could enable us to observe a distinction involving mixture cure ver sus single agent CCI 779 remedy in Tsc2 mice, and these issues will be deemed in the design of long term pre scientific scientific studies. It was shocking to see that when we com pare the group dealt with with solitary agent CCI 779 from 2 4 months to the team treated with CCI 779 as well as IFN from 2 4 months, solitary agent CCI 779 appears to be like signifi cantly superior than combination therapy. This discovering is puzzling as it is not reliable with other treat ment time factors in this analyze or findings in our prior studies on mix treatment, and we do not have a very good rationalization for this variation. Considering that neither two 4 thirty day period treatment group differed considerably from the untreated management team, we conclude that the variation amongst CCI 779 and combination therapy at this time is not essential. Decline of heterozygosity has been noticed in kidney angi omyolipomas andsubependymalgiantcell tumors. Due to the fact TSC is a tumor suppressor gene syn drome, nude mice bearing Tsc2 tumors are a useful generic design for TSC relevant tumors.
