CCl4 treatment led to differential lncRNA expression in murine hepatocytes

Five-week old male C57BL/6J mice (20 ± 2 g) were intraperitoneally injected with of 20% CCl4 solution in sterile mineral oil at a dose of 2.5 ml CCl4 per kilogram body weight twice per week for eight weeks. Afterwards, the primary hepatocytes were isolated by pronase/collagenase perfusion digestion followed by subsequent density gradient centrifugation. The isolated primary hepatocytes were counted with a hemocytometer to determine the number and percentage of viable cells using the trypan blue method. The isolated cells with the viability above 90% were used for the experiments. Overall design: Total RNA was extracted from the isolated hepatocytes with TRIzol reagent.
