Abstract Poly(ADP-ribose) is a nuclear polynucleotide involved in the regulation of chromatin functions via covalent and/or noncovalent modification of nuclear proteins. Using a binding assay on protein blots, we searched for poly(ADP-ribose) binding proteins in nuclear matrices from testes of differently aged rats as well as from various adult rat tissues (brain, liver, spleen). We found that nuclear matrix proteins represent a significant subset of the nuclear proteins that can establish noncovalent interactions with poly(ADP-ribose). The profiles of poly(ADP-ribose) binding nuclear matrix proteins appeared to be tissue-specific and changed during postnatal development in the testis. The isolation and analysis of endogenous poly (ADP-ribose) from rat testes showed that the ADP-ribose polymers that bind nuclear matrix proteins in vitro are also present under physiologic conditions in vivo. These results further substantiate the possibility that poly(ADP-ribose) may affect chromatin functions through noncovalent interaction with specific protein targets, including nuclear matrix components.

Gene Regulatory

Participation of the nuclear matrix in regulation of alpha-2-macroglobulin (?2M) gene transcription during rat liver development and the acute-phase (AP) response are examined. DNA affinity chromatography of fetal and adult liver internal nuclear matrix proteins under basal and AP conditions with the ?2M gene promoter (-852/+12) and immunoblot analysis revealed diverse patterns of association of transcription factors with the nuclear matrix. HNF-6, C/EBP?, and STAT5b were involved in basal and C/EBP?, STAT1, and STAT3 in AP-stimulated ?2M expression. These findings support the assumption that transcription factor-nuclear matrix interactions serve to channel gene regulatory proteins to DNA sequences.

Matrix Bound

The nuclear matrix bound DNA fraction of rat testis showed enrichment in repetitive sequences found in the 450 bp band after gel electrophoresis of the MspI digested rat DNA. DNA fragments isolated from this band were cloned. DNA of the clone pMspI8 showed homology to some representatives of rat LINE sequence family, and complexed in vitro more efficiently with testes nuclear matrix proteins than with yeast ARS1 sequence containing the matrix association region (MAR) or DNA from an other clone, MspI19. Western blot analysis showed that MspI8 sequence interacts with testes matrix protein of about 120 kDa.
