Acetylation and phosphorylation of high-mobility group A1 proteins in PC-3 human tumor cells.

Abstract:

:In this paper, we examined the posttranslational modifications (PTMs) of high-mobility group A1 (HMGA1) proteins in PC-3 human prostate cancer cells that are either treated or not treated with a histone deacetylase inhibitor, sodium butyrate. We found that, from a reversed-phase C4 column, the HMGA1a protein eluted in two different fractions with distinct forms of PTMs: Ser98, Ser101, and Ser102 were phosphorylated and Arg25 was methylated for both fractions; only the minor fraction, however, is hyperphosphorylated where Ser35, Thr52, and Thr77 were also phosphorylated. In addition, Lys14 was acetylated in the major but not the minor HMGA1a fraction isolated from the PC-3 cells that were not treated with butyrate. Likewise, HMGA1b, which is a splicing variant of HMGA1a, was acetylated on Lys14 and phosphorylated on the corresponding residues, i.e., Thr41, Thr66, Ser87, Ser90, and Ser91. The acetylation and phosphorylation of the HMGA1a and HMGA1b proteins may affect their interactions with other protein factors, which in turn may modulate the binding of HMGA1 proteins to DNA and regulate gene expression. In addition, the specifically posttranslationally modified HMGA1 proteins may serve as molecular biomarkers for cancer diagnosis and prognosis.
