Homeotic (Hox) genes encode transcription factors that confer segmental identity along the anteroposterior axis of the embryo. However the molecular mechanisms underlying Hox-mediated transcription and the differential requirements for specificity in the r ...
The mis-regulation of gene transcription in the living cell can be the cause of complex human diseases like cancer. One challenge of the post-genomic era of biomedical research is the development of in vitro techniques for the rapid and cost-effective anal ...
Phosphorylation of H2AX (gamma H2AX) is an early sign of DNA damage induced by replication stalling. However, the role of H2AX in the repair of this type of DNA damage is still unclear. In this study, we used an inactivated adeno-associated virus (AAV) to ...
Epigenetic silencing of essential components of DNA repair pathways is a common event in many tumor types, and comprise O6-methylguanine-DNA methyltransferase (MGMT), human mut L homolog 1 (hMLH1), Werner syndrome gene (WRN), breast cancer susceptibility g ...
Lysophosphatidic acid (LPA) and sphingosine 1-phosphate (S1P) are structurally related bioactive lipids with growth factor-like activities. LPA and SIP are naturally produced in vivo by blood platelets upon platelet aggregation and at least in vitro by fib ...
PURPOSE OF REVIEW: The last years of cancer research have established the concept of cancer stem cells (CSCs) as a subpopulation of cells within a tumor entirely responsible for tumorigenesis. This has aroused expectations that targeting cancer stem cells ...
Telomeres, the physical ends of eukaryotic chromosomes, consist of tandem arrays of short DNA repeats and a large set of specialized proteins. A recent analysis has identified telomeric repeat-containing RNA ( TERRA), a large non-coding RNA in animals and ...
Epigenetic mechanisms are not only essential for biological functions requiring stable molecular changes such as the establishment of cell identity and tissue formation, they also constitute dynamic intracellular processes for translating environmental sti ...
KAP1 is an essential cofactor of KRAB zinc finger proteins, a family of vertebrate-specific epigenetic repressors of largely unknown functions encoded in the hundreds by the mouse and human genomes. So far, KRAB/KAP1-mediated gene regulation has been studi ...
DNA-binding proteins mediate a variety of crucial molecular functions, such as transcriptional regulation and chromosome maintenance, replication and repair, which in turn control cell division and differentiation. The roles of these proteins in disease ar ...
