Study of the expression and the role of serglycin in malignancies

Abstract

Serglycin (SG) is the major proteoglycan of hematopoietic origin cells and contributes to the regulation of several inflammatory proteins. Moreover, SG has a significant role in the biology of Multiple Myeloma; It inhibits the activation of the classical and the lectin pathway of complement system. Enhanced SG expression is correlated with the aggressive phenotype of nasopharyngeal cancer cells. In the present study, the expression of SG in several malignancies was investigated. The strong presence of SG in solid tumors due to its elevated expression either by cancer cells or by inflammatory and stomal cells was revealed. Furthermore, SG elevated expression and secretion was correlated with the high metastatic potential of several cancer cell lines. The expression of the alternatively spliced SG mRNA (variant 2) was identified. This variant lacks exon 2.The role of SG in the biology of aggressive breast cancer cells was studied. SG interacts with significant mediators of actin cytoskel ...
