For instance, hsa_circ_0007142 is upregulated and promotes cell proliferation in colorectal cancer [7]; in non-small cell lung cancer cell lines, hsa_circ_100146 is highly expressed [8]; in CCA cells, hsa_circ_0001649 is downregulated and exhibits tumor-suppressive activity [9]; and circRNA Cdr1as is upregulated in CCA cells and associated with poor prognosis [10]. The gene discussed is LINC00632; the disease is cholangiocarcinoma.
