Quantification of protein Z expression in lung adenocarcinoma tissues and cells.

Wang H, Huang F, Pan XY, Guan ZB, Zeng WB, Li MJ, Zhang RH - Springerplus (2016)

Bottom Line: In tissues and cells, PZ protein and gene expression were determined using western blot, immunohistochemistry and PCR.Only protein expression was increased in cultured cell lines, which holds implications for the dominant source of PZ in tissues, as well as protein modifications necessary for PZ function.Protein Z appears to be associated with the presence of lung adenocarcinoma and may be a viable prognostic biomarker for lung cancer.

ABSTRACT
As a regulator of coagulation, abnormal Protein Z (PZ) expression may lead to the formation of blood clots in humans. While previous studies have shown that PZ protein is altered in several types of cancer, however, additional observations are needed to understand the complex biology involved. Herein, we investigated local alterations in PZ expression in lung adenocarcinomas by measuring gene and protein expression in both cancerous and normal lung tissues. Twenty-two (22) specimens of lung adenocarcinoma and 22 specimens of normal lung tissues from human patients were compared for the expression of PZ. In addition, A549 adenocarcinoma cells were compared to a normal epithelial cell line, 16-HBE, for in vitro PZ expression. In tissues and cells, PZ protein and gene expression were determined using western blot, immunohistochemistry and PCR. Lung adenocarcinoma tissues showed elevated expression of both PZ mRNA and protein compared with healthy tissue. Only protein expression was increased in cultured cell lines, which holds implications for the dominant source of PZ in tissues, as well as protein modifications necessary for PZ function. Protein Z appears to be associated with the presence of lung adenocarcinoma and may be a viable prognostic biomarker for lung cancer.

PZ protein expression is upregulated in cancerous tissue biopsies. Representative Western blots show that PZ expression is highly upregulated in lung adenocarcinoma (LA) tissue compared with normal lung tissue (NLT). Samples were normalized to actin and quantitated (*P = 0.014)

Mentions: We next examined the expression of PZ protein in 22 lung adenocarcinoma and 22 healthy lung tissues via western blotting. Representative images of the membranes shown in Fig. 5 illustrate that PZ expression is significantly increased in cancerous tissues compared with normal lung tissue.Fig. 5
