Figure 4. Cell-autonomous regulation of hepatocyte signaling and gene expression by hnRNPU.
The following experiments were performed in primary hepatocytes prepared from Ctrl or LKO mice. Hepatocytes were cultured in serum-free media overnight before treatments. PA (200 μM) was added 2 hrs prior to the addition of TNFα (20 ng/mL).
(A) Immunoblots of total lysates from hepatocytes treated with vehicle (−) or PA+TNFα (+) for 15 min.
(B) Immunoblots of cytosolic or nuclear extracts from treated hepatocytes.
(C) Immunoblots of total lysates from hepatocytes treated with vehicle (−) or PA+TNFα (+) for 24 hrs.
(D) qPCR analysis of gene expression from hepatocytes treated with vehicle (Veh) or PA+TNFα for 6 hrs (n=3). Data represent mean ± SEM. **P<0.01, Ctrl vs. LKO in vehicle-treated cells. #P<0.05, ##P<0.01, Ctrl vs. LKO in hepatocytes treated with PA+TNFα. Two-way ANOVA with multiple comparisons.
