(a) Effects of insoluble-bound fraction and caffeic acid on the protein expression levels of Bax, Bcl-2, and cytochrome C, (b) the relative protein expression levels. Protein expression levels were normalized with β-actin according to grayscale. Data are expressed as mean ± SD (n = 3). In Figure 6(b), mean values with different letters are significantly different (). CK: control group; BSA: BSA/NaOH complex solution; PA: PA/BSA complex solution; Bax: Bcl-2-associated X protein; Bcl-2: B cell lymphoma-2; IB: insoluble-bound phenolic fraction; U-IB: UHP-treated insoluble-bound phenolic fraction.
