Abstract
RHOA, RHOB, and RHOC comprise a subfamily of RHO GTPase proteins famed for controlling cytoskeletal dynamics. RHO proteins operate downstream of multiple signals emerging from the microenvironment, leading to diverse cell responses, such as proliferation, adhesion, and migration. Therefore, RHO signaling has been centrally placed in the regulation of blood cells. Despite their high homology, unique roles of RHOA, RHOB, and RHOC have been described in hematopoietic cells. In this article, we overview the contribution of RHO proteins in the development and function of each blood cell lineage. Additionally, we highlight the aberrations of the RHO signaling pathways found in hematological malignancies, providing clues for the identification of new therapeutic targets.
期刊介绍：
The Journal of Cellular Physiology publishes reports of high biological significance in areas of eukaryotic cell biology and physiology, focusing on those articles that adopt a molecular mechanistic approach to investigate cell structure and function. There is appreciation for the application of cellular, biochemical, molecular and in vivo genetic approaches, as well as the power of genomics, proteomics, bioinformatics and systems biology. In particular, the Journal encourages submission of high-interest papers investigating the genetic and epigenetic regulation of proliferation and phenotype as well as cell fate and lineage commitment by growth factors, cytokines and their cognate receptors and signal transduction pathways that influence the expression, integration and activities of these physiological mediators. Similarly, the Journal encourages submission of manuscripts exploring the regulation of growth and differentiation by cell adhesion molecules in addition to the interplay between these processes and those induced by growth factors and cytokines. Studies on the genes and processes that regulate cell cycle progression and phase transition in eukaryotic cells, and the mechanisms that determine whether cells enter quiescence, proliferate or undergo apoptosis are also welcomed. Submission of papers that address contributions of the extracellular matrix to cellular phenotypes and physiological control as well as regulatory mechanisms governing fertilization, embryogenesis, gametogenesis, cell fate, lineage commitment, differentiation, development and dynamic parameters of cell motility are encouraged. Finally, the investigation of stem cells and changes that differentiate cancer cells from normal cells including studies on the properties and functions of oncogenes and tumor suppressor genes will remain as one of the major interests of the Journal.
