Inhibition of PRRX2 suppressed colon cancer liver metastasis via inactivation of Wnt/β-catenin signaling pathway.

The aim of this study was to investigate whether PRRX2 may regulate the liver metastasis of colon cancer via the Wnt/β-catenin signaling pathway. PRRX2 and β-catenin in patients with the liver metastases of colon cancer was detected by immunochemistry. Colon cancer cells (CT-26 and CMT93) were divided into Normal, si-Ctrl, si-PRRX2 and si-PRRX2 +LiCl groups.

Upregulated long-non-coding RNA DLEU2 exon 9 expression was an independent indicator of unfavorable overall survival in patients with esophageal adenocarcinoma.

In this study, we aimed to explore the expression profiles of some known functional lncRNAs in esophageal adenocarcinoma (EAD) and to screening the potential prognostic makers, using data from The Cancer Genome Atlas (TCGA)-esophageal carcinoma (ESCA). Results showed that DLEU2 is a high potential OS related marker among 73 functional lncRNAs. DLEU2 and its intronic miR-15a and miR-16-1 expression were significantly upregulated in EAD compared with adjacent normal tissues.

MFAP2 promotes epithelial-mesenchymal transition in gastric cancer cells by activating TGF-β/SMAD2/3 signaling pathway.

Introduction: Microfibril-associated protein 2 (MFAP2) is an extracellular matrix protein that interacts with fibrillin to modulate the function of microfibrils. MFAP2 has been reported to play a significant role in obesity, diabetes, and osteopenia, and has been shown to be upregulated in head and neck squamous cell carcinoma. However, the molecular function and prognostic value of MFAP2 have never been reported in gastric cancer (GC) or any other tumors.

Blockage of PTPRJ promotes cell growth and resistance to 5-FU through activation of JAK1/STAT3 in the cervical carcinoma cell line C33A.

Gene therapy is a promising therapeutic approach for chemoresistant cervical cancers. Therapeutic interventions targeting the key factors contributing to the initiation and progression of cervical cancer may be a more effective treatment strategy. In the present study, we firstly determined the expression of protein tyrosine phosphatase receptor J (PTPRJ) in 8-paired human cervical tumor and non-tumor tissues.

Oleuropein induces apoptosis via activation of caspases and suppression of phosphatidylinositol 3-kinase/protein kinase B pathway in HepG2 human hepatoma cell line.

Oleuropein is a polyphenol, that is found in extra‑virgin olive oil. Previous studies have shown that oleuropein inhibits cell proliferation and induces apoptosis in breast cancer, colorectal cancer and thyroid cancer. The aim of the present study was to investigate the effects of oleuropein in hepatocellular carcinoma (HCC) cells.

Changes of serum p53 antibodies and clinical significance of radiotherapy for esophageal squamous cell carcinoma.

Aim: To explore the relationship between serum p53 antibodies (p53-Abs) and clinicopathological characteristics and therapeutic effect in patients with esophageal carcinoma (EC), and to investigate sequential changing regularity of serum p53-Abs after radiotherapy.

Methods: The serum p53-Ab levels were detected in 46 EC patients and 30 healthy adults by enzyme linked immunosorbent assay (ELISA). The blood samples were collected on the day before radiotherapy and on the administration of an irradiation dose of 20 Gy/10 f/12 d, 40 Gy/20 f/24 d and 60 Gy/30 f/36 d after radiotherapy.

[Treatment effect of percutaneous vertebroplasty combined with interventional chemotherapy on vertebral metastases].

Background & Objective: Vertebral metastasis is a common manifestation of patients with advanced cancer without effective treatment. This study was to explore treatment value and efficacy of percutaneous vertebroplasty (PVP) combined with interventional chemotherapy on vertebral metastases.

Methods: Seventy-five patients with vertebral metastases (42 men, 33 women; aged 31-76 years) were divided into 2 groups: 39 were treated by PVP combined with chemotherapy (VPCC group), and 36 were treated by PVP alone (VP group).
