Figure 4: Effects of Portulaca extract on apoptosis in mice on inflammatory bowel disease. Panel (a) shows the protein level of Bcl-2, Bax, caspase 3, and cleaved caspase 3 in each group. Panel (b) represents the histogram of density for Bcl-2, Bax, and cleaved caspase 3. Panel (c) represents the relative mRNA level of Bcl-2 and Bax from quantitative real-time PCR, respectively. (Data are presented as mean ± SD from six experiments. indicates comparison between DSS and NC; # indicates comparison between mesalamine and DSS; + indicates the comparison between Portulaca and DSS. The number of symbols indicates significance of difference; for example, four symbols indicate ; three symbols indicate ; two symbols indicate ; and one symbol indicates .)
