Highlights |
• | CCT6A protein and CCT6A mRNA were higher in HCC tumor tissue than adjacent tissue. |
• | CCT6A protein correlated with unfavorable tumor features in HCC patients. |
• | CCT6A mRNA correlated with unfavorable tumor features in HCC patients. |
• | CCT6A protein and mRNA associated with poor accumulating OS in HCC patients. |
• | CCT6A protein high (vs. low) independently predicted shorter OS in HCC patients. |
Abstract |
Background |
Chaperonin-containing tailless complex polypeptide 1 subunit 6A (CCT6A) plays roles in cancer progression, but its clinical implication in hepatocellular carcinoma (HCC) management needs further exploration. This study aimed to explore the correlation of CCT6A with clinical characteristics, liver function indexes, tumor markers and prognosis in HCC patients.
Methods |
240 HCC patients were retrospectively enrolled. 240 pairs of cancer and adjacent specimens were used to evaluate CCT6A protein expression by immunohistochemistry assay; among which 184 pairs were used to assess CCT6A mRNA expression by reverse transcription-quantitative polymerase chain reaction.
Results |
Both CCT6A protein expression and CCT6A mRNA expression were higher in HCC tumor tissue than in adjacent tissue (P < 0.001). The receiver operating characteristic (ROC) curve showed that CCT6A had certain potential in discriminating tumor tissues from adjacent tissues. In addition, CCT6A protein expression was positively correlated with multifocal tumor nodule (P = 0.001), ≥ 5.0 cm tumor size (P = 0.028), BCLC stage (P = 0.002) and abnormal AFP (P = 0.021). Besides, CCT6A mRNA expression was associated with multifocal tumor nodule (P = 0.025), ≥ 5.0 cm tumor size (P = 0.018), higher BCLC stage (P = 0.036), abnormal CA199 (P = 0.027) and abnormal AFP (P = 0.008). However, no correlation was found in CCT6A with liver function indexes (all P ≥ 0.05). Moreover, CCT6A protein and mRNA high expressions were both correlated with poor accumulating overall survival (OS) (P = 0.004, P = 0.002, respectively). Furthermore, CCT6A protein high expression (vs. low) independently predicted shorter OS (P = 0.027).
Conclusions |
CCT6A serves as a possible biomarker reflecting tumor features and prognostication in HCC patients.
