The protein kinase inhibitor staurosporine (SSP) was employed to study the involvement of kinases in human cell cycle progression. Thirty to 100 ng/ml SSP blocks entry into S phase and M phase. Lack of entry into S phase is due to impaired activity o

Previous studies have shown that retinoic acid (RA), similar to tumor necrosis factor-alpha (TNF-alpha), can act as a bifunctional regulator of the growth of bone marrow progenitors, in that it can stimulate granulocyte-macrophage colony-stimulating

In the present paper we demonstrate that physiologic levels (10 nM) of both all-trans- and 9-cis-retinoic acid (RA) are potent inhibitors of the growth of human as well as murine B cell precursors in vitro. Ten nanomolar concentrations of all-trans-

TGF-beta and agents that elevate intracellular cAMP levels are potent inhibitors of B cell activation in vitro and have been shown to arrest stimulated B cells in the G1 phase of the cell cycle. We tested the effects of TGF-beta 1 and the cAMP-induci

The CD53 pan-leukocyte glycoprotein is a member of the recently described tetraspan family of cell membrane proteins. The structure and functional characteristics of these molecules indicate that they may play important roles in transmembrane signali

Within the hematopoietic system, CDw75 is primarily expressed on cells of the B cell lineage. Cloning and sequencing of the gene has shown CDw75 to be a beta-galactoside alpha-2,6-sialyltransferase. This enzyme plays an important role in the intracel

cAMP is an important physiological mediator of lymphoid growth inhibition. The purpose of the present study was to establish the link between cAMP and the cell cycle machinery leading to inhibition of G1/S transition in human peripheral blood lymphoc

The mechanisms underlying the growth-inhibitory effect of retinoids on normal human B lymphocytes are not well understood. We addressed this issue by examining the effect of retinoic acid on the cell cycle machinery involved in G1/S transition. When

During B- and T-cell ontogeny, extensive apoptosis occurs at distinct stages of development. Agents that increase intracellular levels of cAMP induce apoptosis in thymocytes and mature B cells, prompting us to investigate the role of cAMP signaling i

The protein Mad1 heterodimerizes with Max to form an E-box binding complex able to interfere with the transcriptional and transforming activities of c-Myc. Downregulation of c-Myc accompanied by induction of Mad1 upon differentiation has fueled the n
