Abstract

Metastatic growth is the leading cause of cancer-related death in non-small cell lung cancer (NSCLC). Metastasis is believed to be initiated by an increase in cell motility mediated by the loss of cell-cell adhesion because of the suppression of E-cadherin [encoded by cadherin 1 ( CDH1)]. However, very little is known about the molecular mechanism of CDH1 regulation. Therefore, we hypothesized that non-small cell lung cancer-associated transcript-1 (NSCLCAT1) suppresses functional CDH1 and mediates the Hippo signaling pathway, resulting in increased cell migration and invasion, and reduced apoptosis. Initially, microarray profiling and target prediction programs were employed to identify whether NSCLCAT1 targets CDH1. Next, quantitative PCR was used to determine the expression pattern of NSCLCAT1 in 114 specimens. The biologic functions of NSCLCAT1 in NSCLC were assessed through the up-regulation and down-regulation of the levels of endogenous NSCLCAT1 with the use of NSCLCAT1 vector or small interfering RNA against NSCLCAT1 in NSCLC cells. Furthermore, the Hippo signaling pathway in NSCLC cells was blocked by applying the verteporfin treatment to have a better understanding on the pivotal role of the Hippo signaling pathway in...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. Discover the latest research on cadherins and catenins here.
