PTK2 and cervical carcinoma: In cervical cancer, there is a low expression of miR-7, especially in metastatic tumors; however, the ectopic expression of said miRNA significantly inhibits FAK in HeLa and C33A cells, a protein involved in the regulation of cell proliferation and survival at the transcriptional and protein levels, which correlates with the negative correlation of miR-7 and FAK in cervical cancer tissues [30].
