Abstract

This study aimed to investigate the role of ANXA13 in lung adenocarcinoma (LUAD) growth, migration, and the underlying mechanisms. Firstly, in the TCGA dataset for LUAD, ANXA13 is found to be highly expressed in patients with LUAD and high expression of ANXA13 predicted poor outcomes in LUAD patients. Consistently, the data of qRT-PCR showed that the expression of ANXA13 was higher in LUAD cell lines (Calu-3, LTEP-a-2, and NCI-H1395) than that in normal lung cell line BEAS2B. Then, we performed gain- and loss of function of ANXA13 in NCI-H1395 and Calu-3 cells, respectively. The results displayed that deficiency of ANXA13 suppresses cell proliferation, invasion, and migration in Calu-3 cells and overexpression of ANXA13 augments cell proliferation, invasion, and migration in NCI-H1395 cells. Finally, it was found that silencing of ANXA13 obviously raised the protein expression levels of E-cadherin and reduced the protein levels of N-cadherin, Vimentin, and Snail in Calu-3 cells whereas overexpression of ANXA13 obviously receded the protein expression levels of E-cadherin and enhanced the protein levels of N-cadherin, Vimentin, and Snail in NCI-H1395 cells. This study analyzed the biological effects of ANXA13 in LUAD cells, indi...Continue Reading

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.

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.
