Expression and putative protein structure of transcription-involved protein upregulated in HCC (TIPUH1). (a) Semiquantitative RT–PCR analysis of TIPUH1 in 10 HCCs (T) and their corresponding noncancerous liver tissues (N). Expression of GAPDH served as a control. (b) Expression of TIPUH1 in hepatoma cells and noncancerous liver tissue. (c) Northern blot analysis of TIPUH1 in a panel of 16 normal adult human tissues. β-Actin served as a control. (d) Schematic presentation of putative structure of TIPUH1 protein.
