Next, increased expression of LINC00636 was found to be significantly up-regulated in cancer tissues (Figure 1A) and the serum (Figure 1B) of cervical cancer patients with lymph node metastasis compared with non-metastatic patients, which was similar with results downloaded from The Cancer Genome Atlas (TCGA) (Figure 1C) and LINC00636 overexpression have poor prognosis in cervical cancer patients (Figure 1D). Here, LINC00636 is linked to cervical carcinoma.
