Our data indicate that ATXN1 promotes cyclin D1 expression through the EGFR–RAS–MAPK signaling pathway, resulting in the proliferation of cervical cancer cells, as shown in Figure 3I, and that EGF is a potent inducer of ATXN1, pERK1/2, pMEK1/2, and pMSK1 in cervical cancer cells. The gene discussed is CCND1; the disease is cervical carcinoma.
