The metastatic potential of colorectal cancer (CRC) is intensively promoted by the tumor microenvironment (TME) in a paracrine manner. As pleiotropic inflammatory cytokine, Interleukin-6 (IL-6) produced and involved CRC, same scenario where integrin α v β 6 also becomes upregulated. However, relationship between IL-6 as well their involvement crosstalk CRC TME remains largely unclear. In present study, we demonstrated positive correlation expression samples. mutually promotive interaction...

Methylation of gene promoter CpG islands is an important early event in hepatocellular carcinoma (HCC), and detection cell‐free tumor‐specific DNA methylation becoming a useful noninvasive method for HCC. This study was aimed at determining the diagnostic value serum insulin‐like growth factor‐binding protein 7 ( IGFBP7 ) hepatitis B virus‐associated A total 217 subjects, including 136 HCC patients, 46 patients with chronic (CHB), 35 healthy controls (HCs), were included. The status...

BACKGROUND Hepatocellular carcinoma (HCC) is the sixth most common type of cancer and fourth leading cause cancer-related death worldwide. Sarcomatoid HCC, which contains poorly differentiated carcinomatous sarcomatous components, a rare histological subtype HCC that differs from conventional HCC. It highly aggressive has poor prognosis. Its clinicopathological characteristics, surgical outcomes underlying mechanisms its nature have not been fully elucidated. AIM To examine characteristics...

Several studies have revealed that MFG-E8 (milk fat globule–epidermal growth factor 8) is related to tumour development and progression. However, the relationship between expression metastasis in colorectal cancer patients role of invasion progression remain unknown. In this study, we performed immunohistochemistry quantitative real-time polymerase chain reaction assess adjacent non-cancerous tissues. Colorectal RNAseq data from The Cancer Genome Atlas project were downloaded was analysed....
