Advanced Science, EarlyView.Schematic illustration of the proposed model. Primary CAFs are isolated from fresh human GBM specimens according to established protocols. GLUL is essential for pro‐angiogenic capacity of CAFs through its impact on the PI3K/AKT pathway. GLUL enhances the pro‐angiogenic capacity of CAFs, driving aberrant tumor vasculature that fuels tumor growth ...

A New Type of YumC-Like Ferredoxin (Flavodoxin) Reductase Is Involved in Ribonucleotide Reduction
mBio, 2015 The trxB2 gene, which is annotated as a thioredoxin reductase, was found to be essential for growth of Lactococcus lactis in the presence of oxygen. The corresponding protein (TrxB2) showed a high similarity with Bacillus subtilis YumC (E value = 4.0E−88)
