E3 ubiquitin ligases mediate the last step of the ubiquitination pathwayin the ubiquitin-proteasome system (UPS). By targeting transcriptional regulators for their turnover, E3s play a crucial role in every aspect of plant biology. In plants, SKP1/CULLIN1/F-BOX PROTEIN (SCF)-type E3 ubiquitin ligase...
Suppressive HAART does not eradicate HIV-1 and viral DNA persists as a stably integrated form in the absence of viral particle production. As a consequence, latent reservoirs are refractory to antiretroviral drugs and invisible to immune surveillance. The largest latent reservoir consists of resting...
Cell fate transitions involve integration of genomic information encoded by regulatory elements, such as enhancers, with the cellular environment. However, identification of the genomic sequences that control the earliest steps of human embryonic development represents a formidable challenge. Here w...

BACKGROUND: Robustness of mathematical models of biochemical networks is impo...
Biological oscillations are observed at many levels of cellular organization. In the social amoebae Dictyostelium discoideum, starvation-triggered multicellular development is organized by periodic cAMP waves, which provide both chemoattractant gradients and developmental signals. We report that Gta...
We have developed Whole Genome Bisulfite Sequencing (WGBS) of a newborn and a centenarian to address the epigenetic drifts in human aging, which might be an alternative pathway to explain the age-associated alterations. In addition, we have analyzed the methylome of a middle-age donor (26 years). Ex...
