Figure 3. 4-HS expression of JNK/MANK signaling pathway and proliferation-related proteins. (A) Western blot assay to detect the changes in the expression of JNK, p-JNK, p38 MAPK, and p-p38MAPK proteins in PASMC after treatment. (B) Western blot assay to detect the changes in the expression of CDK2, CyclinD1, and PCNA proteins in PASMC after treatment.
