Nanocellulose including cellulose nanocrystal (CNC) and cellulose nanofiber (CNF) has attracted much attention due to its exceptional mechanical, chemical, and rheological properties. Although considered biocompatible, recent reports have demonstrated nanocellulose can be hazardous, including serving as drug carriers that accumulate in the liver. However, the nanocellulose effects on liver cells,...
2D boron nitride (BN) and molybdenum disulfide (MoS2) materials are increasingly being used for applications due to novel chemical, electronic, and optical properties. Although generally considered biocompatible, recent data have shown that BN and MoS2 could potentially be hazardous under some biological conditions, for example, during, biodistribution of drug carriers or imaging agents to the liver...
The mitochondrial damage induced by cadmium has been well established, but its mechanism and its relationship with cadmium-induced apoptosis are elusive until now. Our research showed that cadmium could directly lead to the dysfunction of isolated mitochondria from mouse liver, including the inhibition of respiration, the opening of permeability transition pore (PTP), the loss of transmembrane potential,...
We recently described that there is a feedback amplification of cytochrome c release from mitochondria by caspases. Here we investigated how caspases impact on mitochondria to induce cytochrome c release and found that recombinant caspase-3 induced opening of permeability transition pore and reduction of membrane potential in vitro. These events were inhibited by Bcl-xL, cyclosporin A and z-VAD.fmk...
