Soft-to-hard templating to well-dispersed N-doped mesoporous carbon nanospheres via one-pot carbon/silica source copolymerization
Here we report a new approach referred as “soft-to-hard templating” strategy via the copolymerization of carbon source (dopamine) and silica source (tetraethyl orthosilicate) for the synthesis of well disperse...

Local conformation transitions of linear DNA induced by cisplatin
Cisplatin is the most successful anti-tumor drug, and its pharmacological property is generally considered to derive from the modification of DNA molecules. Structural modifications of short DNA induced by cis...

Open AccessDNA damage stress induces the dissociation of Smurf1/2 from MDM2 in a slow manner
The tumor suppressor p53 locates at the key point of cell growth or apoptosis balance, and the expression level of p53 is tightly controlled by ubiquitin ligases including MDM2. Upon DNA damage stresses, p53 w...
