We further identified the colocalization of endogenous TRF2 and NOLC1 in HEK293T (Fig. 1d and Figure S1A) and hepatoma carcinoma cell SMMC7721 (Figure S1B, first line), but not in cervical cancer HeLa cells (Figure S1B, second line), which was consistent with our previous findings, although we have not found a reasonable explanation so far for the cell-line differences. The gene discussed is NOLC1; the disease is cervical carcinoma.
