Phospholipase Cg2 (PLCg2) induces apoptosis of immune and tumor cells; however, it remains unclear whether PLCg2 promotes hepatocyte apoptosis during liver regeneration (LR). Therefore, to establish a framework for further exploring the function of PLCg2, we generated recombinant adenoviruses carrying a template encoding short hairpin (sh)-RNA targeting PLCg2 (Ad-PLCg2-shRNA), which were used to silence the expression of PLCg2 in BRL-3A cells. First, three pairs of PLCg2-shRNAs were designed, synthesized, and cloned into a shuttle vector, pHBAd-U6-GFP, after annealing.
Currently, there is no practical and efficient method for the isolation of bone marrow cells (BMCs) from rat femurs and tibiae. Here, we attempted to develop a rapid, simple, effective, and non-contaminating method for the isolation of BMCs from rat femurs and tibiae. Rat femurs and tibiae were dissected from the ankle to the hip joint; subsequently, a three-step “locate-slide-twist” procedure was performed using scissors and forceps to remove the femurs and tibiae completely, from the surrounding musculature. The bones were flushed with phosphate-buffered saline to harvest BMCs.
A simple, sensitive and specific liquid chromatography-tandem mass spectrometry method was developed and validated for the determination of auraptene, a constituent isolated from Fructus aurantii with potential to combat Alzheimer’s disease, in rat plasma. Rat plasma samples were pretreated by protein precipitation with methanol. The analytes were separated by a Waters Sun Fire C18 column (50 mm x 2 mm, 5 μm) and eluted with 1:1000 methanol and formic acid/water (v/v) mobile phase with a flow rate of 0.5 mL/min.
