One of the drawbacks in using tissue engineering to repair, and ultimately restore and regenerate the microenvironment, is that many of the factors used to promote these processes can also facilitate tumor survival, growth and metastasis, such as is the case with factors targeting improving angiogenesis (as reviewed in Zimmerlin et al., 2013)
Inhibitors 6 - 8 were incubated with TGR with and without NADPH, and the inhibition of TGR activity was determined after adding a second aliquot of NADPH and 5,5-dithiobis (2-nitrobenzoic acid) (DTNB)
These molecular rhythms define circadian therapeutic windows that have been validated in preclinical models

However, these increases were time dependent, and the levels returned to normal after about 1 month
