Moreover, by decreasing the phosphorylation level of p38 and the amount of reactive oxygen species in cells, the expansion of A549 lung cancer cells is inhibited.[9] Salidroside, in addition, has the capacity to augment Bax expression and diminish Bcl-2 expression in tumor tissues, thus hindering the proliferation of tumor cells, inducing their apoptosis, and give play to an anti-tumor effect. Here, MAPK1 is linked to neoplasm.
