Correlation between SPARC, TGF β1, Endoglin and angiogenesis mechanism in lung cancer.

Correlation between SPARC, TGFβ1, Endoglin and angiogenesis mechanism in lung cancer. J Biol Regul Homeost Agents. 2018 Nov-Dec;32(6):1525-1531 Authors: Wang B, Zhang Z, Tang J, Tao H, Zhang Z Abstract To study the relationship between Secreted protein, acidic and rich in cysteine (SPARC), Transforming growth factorβ1 (TGFβ1), Endoglin and angiogenesis in lung cancer, 40 cases of lung cancer specimens and 40 adjacent normal lung tissues specimens were collected and 10 cases from each were selected for preparation of tissue chip. CD34 (endothelial cell marker), Endoglin human α-Smooth muscle actin, and (α-SMA) markers were performed by immunohistochemical staining, and the immuno-phenotype and the relationship between different morphologies of the microvascular wall components were evaluated. The expression of SPARC mRNA and protein, TGFβ1 mRNA and protein and Endoglin in the remaining 30 cases of lung cancer were detected by immunohistochemistry and in-situ hybridization. The result shows that the positive rates of SPARC, TGFβ1 and Endoglin in lung cancer tissues were significantly higher than those in adjacent normal lung tissues (P less than 0.05). The expression of SPARC and TGFβ1 was negatively correlated with lung cancer. When the positive expression of SPARC increased, the micro-vessel density (MVD) marked by Endoglin decreased gradually; while the positive expression of TGFβ1 increased, MVD increased gradually, and SP...
