Article Abstract
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.

This study provides a resource for kidney (cell type-specific) long noncoding (lnc)RNA expression and demonstrates the importance of lncRNAs in renal health. We identified 174 cell type-specific lncRNAs in the human kidney, with 54 showing altered expression in diabetic kidney disease. TCF21 antisense RNA inducing promoter demethylation (TARID), a podocyte-specific lncRNA upregulated in diabetic kidney disease, is crucial for actin cytoskeleton reorganization in podocytes.

Transformation of cardiac fibroblasts into matrix-producing myofibroblasts plays an important role in tissue repair and fibrosis after myocardial injury. Tcf21 is a basic helix-loop-helix transcription factor that is essential for the development of cardiac fibroblasts and the epicardium. Myofibroblasts are derived from Tcf21 (+) residual fibroblasts; however, whether Tcf21 itself promotes fibrosis is still unknown.

Background: Among the many malignancies, lung adenocarcinoma (LUAD) is a top global health and life risk. The focus of this research is to explore how the TCF21/ERO1A pathway influences the immune escape mechanisms triggered by aerobic glycolysis in LUAD.
Methods: After downloading mRNA expression data from TCGA-LUAD and conducting differential expression analysis, we identified our target mRNA based on literature review.

The lateral plate mesoderm of vertebrates, which borders the other mesodermal territories, develops during embryogenesis into a variety of tissues and organs such as blood, heart, vasculature, kidney and smooth muscles. This mesoderm compartment, as well as the unsegmented pharyngeal mesoderm which gives rise to head muscles and part of the heart, have been proposed as vertebrate innovations. Indeed, in the two other chordate clades, the tunicates and the cephalochordates, no such mesoderm regions are formed during development.

Background: Lung squamous cell carcinoma (LUSC) is a leading cause of cancer-related mortality, and tumor heterogeneity could result in diverse prognostic subtypes. Traditional prognostic factors, like tumor, node, and metastasis (TNM) staging, offer limited predictive accuracy. This study aims to identify LUSC subtypes and develop predictive models that have the potential to improve prognosis prediction accuracy and support personalized treatment.
