circ-LAMP1 directly sponged miR-556-5p and miR-567, thereby releasing their suppression on YY1 at post-transcriptional level. Rescue assay indicated that the oncogenic role of circ-LAMP1 is partially dependent on its modulation of YY1 in CCA.
Circ-LAMP1 contributes to the growth and metastasis of cholangiocarcinoma via miR-556-5p and miR-567 mediated YY1 activation.
