Specificity, propagation and memory of pericentric heterochromatin. Mol. Syst. Biol. 10:746. doi: 10.15252/msb.20145377 A theoretical framework was developed that describes the spatial extension, stability and propagation of histone modification domains via a 'nucleation and looping' mechanism for a prototypic model system of epigenetic silencing.

Bhattacharya, N., Caudron-Herger, M., Haebe, S., Brady, N., Diener, S., Nothing, M., Dohner, H., Stilgenbauer, S., Rippe, K., and Mertens, D. (2014). Loss of cooperativity of secreted CD40L dose-response on CLL cell viability correlates with enhanced activation of NF-kB. Int J Cancer 136:65-73. doi: 10.1002/ijc.28974 To understand the molecular mechanism of the environment-dependent anti-apoptotic signaling circuitry of CLL cells, an approach was introduced to quantify the effect ligands on the survival of in vitro cultured CLL cells. This works includes the establishment of high-resolution and high-throughput microscopy approaches to evaluate chromatin organization/density and the spatial localization of cellular features by immunostaining.
