Calcium phosphate precipitates (CPPs) form complexes with DNA, which enter cells via endocytosis. Under this condition CPPs induce autophagy via the canonic autophagy machinery. Here we showed that CPP-induced autophagy was also dependent on endocytosis as the process was significantly

As an alternative to an autologous bone graft, deproteinized bovine bone (DBB) is widely used in the clinical dentistry. Although DBB provides an osteoconductive scaffold, it is not capable of enhancing bone regeneration because it is not osteoinductive. In order

Replication protein A (RPA) is a single-stranded DNA binding protein that plays an essential role in telomere maintenance. RPA binds to and unfolds G-quadruplex (G4) structures formed in telomeric DNA, thus facilitating lagging strand DNA replication and telomerase activity. To

Diclofenac is a nonsteroidal anti-inflammatory drug. It undergoes hydroxylation by mammalian cytochrome P450 enzymes at 4'- and/or 5'-positions. A bacterial P450 enzyme, CYP105D7 from Streptomyces avermitilis, has been shown to catalyze hydroxylation of 1-deoxypentalenic acid and an isoflavone daidzein. Here
