The interplay of interactions between DNA, RNA and proteins leads to genetic regulatory networks (GRN) and in turn controls the gene regulation. Directly or indirectly in a cell such molecules either interact in a positive or in repressive manner therefore it is hard to obtain the accurate computational models through which the final state of a cell can be predicted with certain accuracy.

A central question in stem cell research is knowing the frequency of human hematopoietic stem cells (HSC) replication in vivo.We have constructed a model that characterizes HSC kinetics and the relative sizes of the hematopoietic progenitor cell (HPC) and HSC pools from birth onward. The model capitalizes on leukocyte telomere length (LTL) data and body weight-gain charts from birth to the age of...
A new human monoclonal antibody (hmAb), designated m16, was selected by sequential antigen panning (SAP) of a human phage display library against recombinant soluble HIV-1 envelope glycoproteins (Envs) (gp140s) and their complexes with soluble CD4. It bound with high (nM) affinity to gp120 and gp140; the binding was further enhanced by interactions of the Envs with CD4. m16 inhibited cell fusion mediated...
