Since Ras and other monomeric G-proteins are processed through the polyisoprenylation pathway in order to be fully functional, it is possible that compounds that interfere with the secondary modifications may have effects on carcinogenesis.
Substrate modifications have already been used to enhance secondary metabolite production and bioactivity of the most popular medicinal polypores, i.e. Reishi (G. lucidum) (You et al. 2012) and Chaga (Inonotus obliquus) (Xu and Zhu 2011).
Some modifications have been made.
To overcome these problems, many modifications have been applied to TiO2 nanomaterials such as doping with a metal coating, surface sensitization, surface area increase or designing, and developing secondary mixed oxides [33, 34].
"Many trial modifications have failed to become permanent modifications.
Altogether, 5.1 million modifications have been started since April 2009.
How many trial and permanent modifications have they made?
Nearly 1 million trial and permanent modifications have been canceled.
Modifications have been made accordingly.
Forward Keith Van Horn said he thought Wilkens's modifications had helped.
The modifications had various effects.
