Chromatin condensation in terminally differentiating mouse erythroblasts does not involve special architectural proteins but depends on histone deacetylationEvgenya Y Popova
Biochemistry and Molecular Biology, College of Medicine, Penn State University, Hershey, PA 17033, USA
Chromosome Res 17:47-64. 2009....
Role of the M-loop and reactive center loop domains in the folding and bridging of nucleosome arrays by MENTEvelyn M Springhetti
Department of Biochemistry and Molecular Biology, Milton S. Hershey Medical Center, Pennsylvania State University College of Medicine, Hershey, Pennsylvania 17033, USA
J Biol Chem 278:43384-93. 2003..Ordered binding of MENT to linker DNA via its unique M-loop domain promotes the folding of chromatin, whereas bridging of chromatin fibers is facilitated by MENT oligomerization mediated by the RCL...
Histone hypercitrullination mediates chromatin decondensation and neutrophil extracellular trap formationYanming Wang
Center for Gene Regulation, Department of Biochemistry and Molecular Biology, Pennsylvania State University, University Park, PA 16802, USA
J Cell Biol 184:205-13. 2009..Together, these results suggest that histone hypercitrullination has important functions in chromatin decondensation in granulocytes/neutrophils...

Rearrangement of upstream sequences of the hTERT gene during cellular immortalizationYuanjun Zhao
Department of Cellular and Molecular Physiology, Pennsylvania State University College of Medicine, Hershey, PA, USA
Genes Chromosomes Cancer 48:963-74. 2009..The chromosomal rearrangements likely occurred during cellular crisis and facilitated by telomere dysfunction. Such translocations allowed the hTERT promoter to escape from the native condensed chromatin environment...
