Abstract

Colorectal cancer represents a great burden for patients worldwide. Long noncoding RNA BX357664 is an RNA that was identified by microarray technique in renal cell carcinoma. The function of BX357664 in solid tumors remains largely unknown. The present study aimed to investigate the expression profile and functional role of BX357664 in human colorectal cancer progression. The transcription levels of BX357664 were initially examined in vivo and in vitro. An overexpression plasmid was constructed in order to examine the effects of BX357664 overexpression on cell proliferation, apoptosis, migration and invasion. The results demonstrated that BX357664 was significantly downregulated in clinical colorectal cancer tissues and cell lines. Overexpression of BX357664 decreased cell proliferation rates and cell colony formation capacities in HCT116 and HT-29 cells. Following BX357664 overexpression, HCT116 and HT-29 cells exhibited reduced migration and invasion capacities. Would closure was also blunted by >50% following overexpression of BX357664 in HCT-116 and HT-29 cells. In addition, the cell cycle regulators Cyclin B1, CDC25C and Cyclin D1 as well as the mesenchymal marker N-cadherin were downregulated, whereas the epithelial marke...Continue Reading

Cell Migration in Cancer and Metastasis

Migration of cancer cells into surrounding tissue and the vasculature is an initial step in tumor metastasis. Discover the latest research on cell migration in cancer and metastasis here.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Cadherins and Catenins

Cadherins (named for "calcium-dependent adhesion") are a type of cell adhesion molecule (CAM) that is important in the formation of adherens junctions to bind cells with each other. Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells: alpha-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins.
