Proteins that modulate the activity of transcription factors, often called modulators, play a critical role in creating tissue- and context-specific gene expression responses to the signals cells receive. GEM (Gene Expression Modulation) is a probabilistic framework that predicts modulators, their affected targets and mode of action by combining gene expression profiles, protein-protein interac...
Most familial breast and ovarian cancers have been linked to mutations in the BRCA1 gene. BRCA1 has been shown to affect gene transcription but how it does so remains elusive. Here we show that BRCA1 can stimulate transcription without the requirement for a DNA-tethering function in mammalian and yeast cells. Furthermore, the BRCA1 C-terminal region can stimulate transcription of the p53-respon...
KSHV is the causative agent of three human proliferative disorders: Kaposi s sarcoma, primary effusion lymphoma, and multicentric Castleman's disease. Herpesvirus gene expression and viral replication is a complex, tightly regulated process involving latent, immediate early, early, and late viral gene transcription. The immediate early genes generally code for transcriptional activators and are...
Objectives: Several studies indicate that amyloid ß (Aß) peptide deposits and neurofibrillary tangles have key roles in pathogenesis and progression of the late-onset Alzhimer’s disease. Likewise it has been shown that inflammatory reactions play a significant role as well. Inflammatory mediators such as complement, chemokines and cytokines activators and inhibitors can releas...
