Facilitating effects of berberine on rat pancreatic islets through modulating hepatic nuclear factor 4 alpha expression and glucokinase activity

Figure 5 Effects of berberine and GB on protein expression of HNF4α. A: A representative Western blot of HNF4α; B: Quantification of HNF4α protein, results were adjusted to GAPDH and expressed as relative density units. Control and GB represent islets of untreated and 1 μmol/L GB treated groups, 1, 3, 10 and 30 represent berberine groups of indicated concentrations. Data are presented as mean ± SD (n = 3). ^aP < 0.05, ^bP < 0.01 vs control.
