The therapeutic response of CDDO-Me in the esophageal squamous cell carcinoma (ESCC) cells is mediated by CaMKIIα.

CDDO-Me has exhibited a potent anticancer effect in human esophageal squamous cell carcinoma (ESCC) cells in our previous study, but the molecular interactome remains elusive. We applied the approach of stable-isotope labeling by amino acids in cell culture (SILAC) to assess the proteomic responses of CDDO-Me treatment in human ESCC Ec109 cells. The data were subsequently validated using Western blot assay.

Effects of glucose administered with lidocaine solution on spinal neurotoxicity in rats.

To investigate whether intrathecal administration of 10% glucose increases functional impairment and histologic damage in rats when mixed with 5% lidocaine. After implanted intrathecal catheter, 32 male Sprague-Dawley rats were randomly assigned to one of four groups: lidocaine group (Group L, n=8) received 5% lidocaine 20 µL, lidocaine with glucose group (Group LG, n=8) received 5% lidocaine with 10% glucose 20 µL, glucose group (Group G, n=8) received 10% glucose 20 µL and normal saline group received normal saline 20 µL (Group NS, n=8). Four days after intrathecal injection, sensory impairments of rats in the four groups were evaluated by using the tail-flick test.

Brucella outer membrane protein Omp25 induces microglial cells in vitro to secrete inflammatory cytokines and inhibit apoptosis.

Omp25 protein, an outer membrane protein of Brucella, can cause damage to the central nervous system. As one type of macrophage, microglial cells play a role in immune surveillance and immune protection in the central nervous system; therefore, they are major targets of bacterial attack. The present study examined BV2 mouse microglial cells that were stimulated with different concentrations of Omp25 recombinant protein, and the secretion of inflammatory cytokines by the BV2 cells as well as their level of apoptosis were observed.
