STAT3 and cervical carcinoma: However, the mRNA expression level of STAT3 between primary cervical cancer and normal tissue is not significantly different (Fig. 1F), and STAT3 correlates positively with LC3B at the mRNA level, which differs from the correlation result at the protein and tissue level (Fig. 1G), which indicates that the regulation of STAT3 in autophagy may be complex in cervical cancer.
