Abstract

Objective This study aims to observe the effects of MLAA-34 gene in leukemia and explore its mechanism. Methods MLAA-34 RNAi vector was constructed. NOD/SCID mice and 293T cells, K562 cells, HL60 cells and U937 cells were used in this study. They were divided into MLAA-34-siRNA group and control group. The proliferation ability and apoptosis of cells were detected. The expression levels of β-Catenin and TCF 4 were determined using western blotting and immunohistochemical methods. Results There was significant correlation between MLAA-34 gene and U937 cell proliferation, the apoptosis rates of U937 cells with siRNA infection were higher than that of control group. There were significant differences in the expression levels of β-Catenin and TCF 4 between U937 cells and U937 with MLAA-34-siRNA cells group. Conclusions MLAA-34 gene had anti-apoptotic effect in leukemia, which maybe through the β-Catenin/TCF 4 pathway.

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

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.

Adherens Junctions

An adherens junction is defined as a cell junction whose cytoplasmic face is linked to the actin cytoskeleton. They can appear as bands encircling the cell (zonula adherens) or as spots of attachment to the extracellular matrix (adhesion plaques). Adherens junctions uniquely disassemble in uterine epithelial cells to allow the blastocyst to penetrate between epithelial cells. Discover the latest research on adherens junctions here.
