Expression of sphingosine-1-phosphate receptor 2 is correlated with migration and invasion of human colon cancer cells: A preliminary clinical study
Oncol Lett. 2022 Jun 1;24(1):241. doi: 10.3892/ol.2022.13361. eCollection 2022 Jul.ABSTRACTSphingosine-1-phosphate (S1P) is a bioactive phospholipid that serves as a potent mediator of cell proliferation, differentiation and apoptosis by binding to S1P receptors (S1PRs). S1P signalling is involved in the pathogenesis of numerous types of disease, including cancer. To the best of our knowledge, however, little is known about the expression patterns of S1PRs and their role in human colorectal cancer (CRC) cell migration and invasion. The aim of the present study was to investigate the role of S1P signalling in the metastasis...

A combination of inhibitors of glycolysis, glutaminolysis and de novo fatty acid synthesis decrease the expression of chemokines in human colon cancer cells.
Authors: Schcolnik-Cabrera A, Dominguez-Gómez G, Chávez-Blanco A, Ramírez-Yautentzi M, Morales-Bárcenas R, Chávez-Díaz J, Taja-Chayeb L, Dueáas-González A Abstract Lonidamine, 6-Diazo-5-oxo-L-norleucine (DON) and orlistat are well known inhibitors of glycolysis, glutaminolysis and of de novo fatty acid synthesis, respectively. Although their antitumor effects have been explored in detail, the potential inhibition of the malignant metabolic phenotype and its influence on the expression of chemokines and growth factors involved in colon cancer, have not been previously reported to the best of our knowledge. I...

Long non-coding RNA-CCAT2 promotes the occurrence of non-small cell lung cancer by regulating the Wnt/ β-catenin signaling pathway.
Long non-coding RNA-CCAT2 promotes the occurrence of non-small cell lung cancer by regulating the Wnt/β-catenin signaling pathway. Oncol Lett. 2018 Oct;16(4):4600-4606 Authors: Zhao C, Qiao C, Zong L, Chen Y Abstract The present study aimed to investigate the biological function of colon cancer-associated transcript 2 (CCAT2) in the occurrence and progression of non-small cell lung carcinoma (NSCLC) and its potential use in the early diagnosis and molecular-targeted therapy of NSCLC. The tumor tissues, para-carcinoma tissues and associated clinical data of 36 patients with NSCLC were collected in orde...

TNF- α promotes colon cancer cell migration and invasion by upregulating TROP-2.
In conclusion, the present results demonstrated that low concentrations of TNF-α significantly enhanced colon cancer cell migration and invasion by upregulating TROP-2 via the ERK1/2 signaling pathway. PMID: 29467899 [PubMed]

Inhibition of BAMBI reduces the viability and motility of colon cancer via activating TGF- β/Smad pathway in vitro and in vivo.
Inhibition of BAMBI reduces the viability and motility of colon cancer via activating TGF-β/Smad pathway in vitro and in vivo. Oncol Lett. 2017 Oct;14(4):4793-4799 Authors: Yu W, Chai H Abstract Colon cancer is a highly metastatic gastrointestinal cancer. BMP activin membrane-bound inhibitor (BAMBI), as a pseudo-receptor of the tumor growth factor (TGF)-β signal transduction pathway, has previously been demonstrated to be involved in human cancers. The present study demonstrated that BAMBI-small interfering (si)RNA regulated the viability and motility of colon cancer by activating TGF-β signaling. T...

Evaluation of antitumor activity of survivin short interfering RNA delivered by lipid nanoparticles in colon cancer in vitro and in vivo.
Authors: Wang T, Liu Z, Zhang Z, Tang S, Yue M, Feng S, Hu M, Xuan L, Chen Y Abstract Survivin has been overexpressed in numerous types of cancer and is associated with a poor clinical outcome. A number of various approaches have been used to counteract survivin in order to inhibit tumor growth or promote cell apoptosis. The present study aimed to evaluate the efficiency and antitumor effect of a survivin-targeted short interfering RNA (siRNA) delivery system using lipid nanoparticles for the treatment of colon cancer. Survivin siRNA (si-survivin) nanoliposomes were prepared and transfected into LoVo cells. The mRN...

Wip1 gene silencing enhances the chemosensitivity of human colon cancer cells.
Authors: Xia ZS, Wu D, Zhong W, Lu XJ, Yu T, Chen QK Abstract Colon cancer is one of the most common cancers in the world. Multidrug resistance is one of the main reasons for failure of therapy in patients with advanced colon cancer. In previous studies, multiple methods were investigated to reverse the multidrug resistance of colon cancer cells. However, to date, no clinical method has been identified to be satisfactory. Therefore, successful reversal of drug resistance in colon cancer cells still requires new therapeutic strategies or pharmaceuticals. Wild-type p53-induced phosphatase (Wip1), a member of the 2C t...

Knockdown of β-catenin by siRNA influences proliferation, apoptosis and invasion of the colon cancer cell line SW480.
Authors: Li K, Zhou ZY, Ji PP, Luo HS Abstract The aim of the present study was to explore the effect of knocking down the expression of β-catenin by small interference (si)RNA on the activity of the Wnt/β-catenin signaling pathway, and the proliferation, apoptosis and invasion abilities of the human colon cancer cell line SW480. For that purpose, double-stranded siRNA targeting β-catenin (β-catenin-siRNA) was synthesized and transfected into SW480 cells. Reverse transcription-polymerase chain reaction (RT-PCR) and western blotting were used to detect the messenger (m)RNA and protein levels of β-catenin in SW4...

Effect of combination therapy of siRNA targeting growth hormone receptor and 5-fluorouracil in hepatic metastasis of colon cancer.
Authors: Zhou D, Zhang YI, Liang D, Yuan Y, Zeng D, Chen J, Yang J Abstract The aim of this study was to investigate the effects of small interfering RNA (siRNA) targeting human growth hormone receptor (hGHR) combined with 5-fluorouracil (5-FU) on the hepatic metastasis of colon cancer. The animal model of liver metastases using human SW480 colon cancer cells was established on BALB/c mice and the siRNA interfering plasmid targeting hGHR gene was constructed. The tumor-bearing mice were randomly divided into the saline control, plasmid, growth hormone (GH), 5-FU, 5-FU+plasmid and 5-FU+plasmid+GH groups. The liver m...
