Effects of Bifidobacterium lactis BLa80 on fecal and mucosal flora and stem cell factor/c-kit signaling pathway in simulated microgravity rats

Figure 3 Expression and data analysis of extracellular signal-regulated kinase and p-extracellular signal-regulated kinase protein in gastric tissue of three groups of rats. A: Extracellular signal-regulated kinase (ERK) and p-ERK protein expression bands detected by Western blotting techniques; B: Histogram of ERK protein expression results; C: Histogram of p-ERK protein expression results. Data are presented as means ± SEM, with n = 3 for each group. ^aP < 0.05; ^bP < 0.01; ERK: Extracellular signal-regulated kinase; Ctrl: Control group; HLS: Tail-hanging group; OST: Tail-hanging administration group.
