Identification of drug transporters contributing to oxaliplatin-induced peripheral neuropathy.

Oxaliplatin is widely used as a key drug in the treatment of colorectal cancer. However, its administration is associated with the dose-limiting adverse effect, peripheral neuropathy. Platinum accumulation in the dorsal root ganglion (DRG) is the major mechanism responsible for oxaliplatin-induced neuropathy.

Enhanced Heat Stability of α-Chymotrypsin through Single-Enzyme Confinement in Attoliter Liposomes.

The entrapment of α-chymotrypsin (α-CT) within 70-140 nm liposomes formed from POPC (1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine) leads to an unexpected and remarkable increase in the thermal stability of the enzyme. This finding is based on the observation that heating aqueous suspensions of α-CT-containing POPC liposomes to 80 °C for 30 minutes resulted in partial enzyme inactivation, whereas the same treatment of aqueous solutions of free α-CT inactivated the enzyme completely. The stabilizing effect of enzyme confinement in the attoliter volumes of the liposomes was found to increase with decreasing numbers of α-CT molecules per liposome.

CD147 promotes the formation of functional osteoclasts through NFATc1 signalling.

CD147, a membrane glycoprotein of the immunoglobulin superfamily, is highly upregulated during dynamic cellular events including tissue remodelling. Elevated CD147 expression is present in the joint of rheumatoid arthritis patients. However, the role of CD147 in bone destruction remains unclear.
