MST4 Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

Novel human Ste20-related kinase Mst4 is highly expressed in placenta, thymus, and peripheral blood leukocytes. Mst4 is biologically active in the activation of MEK/ERK pathway and in mediating cell growth and transformation (1). Wild type and C-terminally truncated forms of Mst4 can both induce apoptosis upon overexpression in mammalian cells that is abrogated by CrmA, suggesting involvement of Mst4 in the apoptotic machinery in mammalian cells (2). Mst4 was found to be expressed in prostate carcinoma tumor samples and cell lines. In addition, expression levels appeared to correlate with tumorigenicity and androgen receptor status of the cells. Mst4 kinase activity was stimulated significantly by epidermal growth factor receptor ligands, which are known to promote growth of prostate cancer cells (3).
