PARP1 and cervical carcinoma: Here, we found that MCPIP1 inhibits cell proliferation and promotes cell apoptosis, which was verified by enhanced apoptotic cells in flow cytometry assay and upregulated protein expression of cleaved caspase-3 and PARP1 in a Western blotting assay after MCPIP1 overexpression in cervical cancer cells (Figure 1).
