Resveratrol alleviates lipopolysaccharide-induced inflammation in PC-12 cells and in rat model.

Abstract:

BACKGROUND:Spinal cord injury (SCI) remains a huge medical problem nowadays as there is no hospital providing the versatile strategies for repairing central nervous system and restoring function. Herein, we focused on PC-12 cells as an important research tool and studied the potential role of resveratrol (RSV) in inflammation induced by LPS. RESULTS:RSV improved inflammatory injury and functional recovery in rat model of SCI. RSV inhibited LPS-induced inflammatory injury in PC-12 cells via increasing viability, decreasing apoptosis, and suppressing IL-1β, IL-6, and TNF-α expression. miR-132 was down-regulated after LPS treatment but up-regulated after RSV administration. miR-132 silence curbed the protective effect of RSV. The results including increase of cell growth, suppression of inflammatory response, and blocking of NF-κB and p38MAPK pathways produced by RSV were all reversed by miR-132 silence. CONCLUSION:RSV could up-regulate miR-132 and further ameliorate inflammatory response in PC-12 cells by inhibiting NF-κB and p38MAPK pathways.

  • Genetic transformation of einkorn (Triticum monococcum L. ssp. monococcum L.), a diploid cultivated wheat species.

    abstract:BACKGROUND:Domesticated einkorn (Triticum monococcum L.) is one of the oldest cultivated cereal crops in the world. Its small genome size (~ 5.7 GB), low ploidy (2n = 2x = 14, AmAm) and high genetic polymorphism make this species very attractive for use as a diploid model for understanding the genomics and proteomics o...
