Background: M2 macrophage-derived exosomes have been identified to modulate hepatocellular carcinoma (HCC) progression. E-twenty-six (ETS) variant transcription factor 4 (ETV4) shows protumoral effects in HCC. Here, we aimed to probe whether ETV4 performed oncogenic effects on HCC by macrophage-derived exosomes and its associated mechanism.

Background: Pancreatic adenocarcinoma (PAAD) is a lethal malignant tumour. Further study is needed to determine the molecular mechanism and identify novel biomarkers of PAAD.

Methods: Gene expression data from the GSE62165 microarray were analysed with the online software Morpheus to identify differentially expressed genes (DEGs).

Background: High expression of inhibitor of DNA binding 1 () correlates with poor prognosis in colorectal cancer (CRC). Aberrant enhancer activation in regulating transcription is limited.

Methods: Immunohistochemistry (IHC), quantitative RT-PCR (RT-qPCR) and Western blotting (WB) were used to determine the expression of .

Purpose: Polymerase δ (POLD) proteins is a pivotal B-family DNA polymerase in the process of genome replication and repair and are comprised of POLD1-4. The predictive value of POLDs in hepatocellular carcinoma (HCC) has not been evaluated until now.

Patients And Methods: A total of 369 hepatocellular carcinoma samples and 50 adjacent normal samples were enrolled from the TCGA-LIHC database, and the GSE10186 database was also used.

LncRNAs exert important functions in the modulation of tumorigenesis and cancer stem cell-like properties in liver cancer. However, the role of LncRNA Ras suppressor protein 1 pseudogene 2 (RSU1P2) in modulating tumorigenesis and cancer stem cell-like properties in liver cancer is still not known. In this study, the expression of LncRNA RSU1P2 was significantly elevated in liver cancer tissues and cells.

Gastric cancer (GC) is a heavy health burden around the world, which is the fifth most frequent tumor and leads to the third most common cancer-related deaths. It is urgent to identify prognostic markers as the guideline for personalized treatment and follow-up. We accessed the prognostic value of Early B-cell factors (EBFs) in GC.

Background: Pancreaticoduodenal artery (PDA) aneurysms are extremely rare. The complicated clinical presentations and high incidence of rupture make it difficult to diagnose and treat. PDA pseudoaneurysms often rupture into the gastrointestinal tract and result in life-threatening gastrointestinal hemorrhage.

NR4A1 acts as an oncogene and plays an important role in colorectal cancer development and progression, but little is known about the regulatory mechanism of NR4A1 expression. MicroRNA (miRNA) is involved in the progression of various tumors, affecting proliferation, apoptosis or migration. We aimed to elucidate whether miRNA regulates NR4A1 expression and determine its underlying significance in colorectal cancer.

Long non-coding RNAs (lncRNAs) play important roles in tumorigenesis and cancer progression. The orphan nuclear receptor subfamily 4 group A member 1 () acts as an oncogene, and is involved in colorectal cancer (CRC) development. However, the mechanism through which lncRNA regulates NR4A1 expression remains unknown.

Sirtuin 5 (SIRT5) belongs to the sirtuin family of protein deacetylases and contributes to tumorigenesis and migration. However, the underlying molecular mechanism of SIRT5 in hepatocellular carcinoma (HCC) migration is not fully understood. Here we report that SIRT5 was significantly downregulated in HCC, based on analysis of RNA-seq data from the liver HCC dataset of The Cancer Genome Atlas (TCGA).

Background: Inflammation is an important hallmark of cancer. Fibrinogen and albumin are both vital factors in systemic inflammation. This study investigated the prognostic value of the fibrinogen/albumin ratio in HCC patients who underwent curative resection.

Hepatocellular carcinoma (HCC) is one of the major malignant tumors that lead to death. Chronic hepatitis B virus infection is an important risk factor for HCC initiation. HBx protein, encoded by the HBV gene, is a significant factor that promotes HBV-related HCC, although the exact molecular mechanism remains unclear.
