Background:
Transcription factor 21 (TCF21) is identified as a tumor suppressor in a variety of human tumors. The purpose of the study was to examine its expression tendency and prognostic value in hepatocellular carcinoma (HCC).
Methods:
Relative expression of TCF21 mRNA in tissue samples from HCC patients and healthy volunteers were detected through quantitative real-time polymerase chain reaction (qRT-PCR) while its protein level was examined via immunohistochemistry analysis. Chi-square test was adopted to assess the association of TCF21 expression with the clinicopathological characteristic of the patients. Then Kaplan-Meier analysis was employed to analyze the function of TCF21 expression on overall survival among HCC patients.
Results:
Both the mRNA and protein levels of TCF21 were significantly reduced in HCC tissue samples compared with healthy controls (p < .05). Also, its expression was obviously affected by the classification of tissue pathology, metastasis, T stage, N stage and pathological grading. According to Kaplan-Meier analysis, patients with higher expression of TCF21 experienced dramatically longer overall survival time than those with lower expression (log rank test, p < .001).
Conclusions:
TCF21 expression was decreased in HCC patients and it could act as a prognostic marker.

Central Tendency: Analysis
The mean is one such measure, calculated by totaling all values in a dataset and dividing by the number of values. For instance, the mean blood pressure reading (120, 130, 140, 150) would be 135. However, the mean can be affected by extreme values or outliers.

What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
