Basic helix-loop-helix genes in neural development.
Several major advances in the understanding of the regulation of vertebrate neurogenesis by members of the basic helix-loop-helix (bHLH) protein family have been made in the past year. Specifically, a number of bHLH genes have been cloned and shown to convert non-neuronal fate to neuronal fate when expressed ectopically. In particular, studies on NeuroD and Neurogenin suggest a regulatory pathw...
متن کاملExpression of basic helix-loop-helix proteins in the glomeruli.
BACKGROUND Basic helix loop helix (bHLH) proteins play a critical role in the differentiation of not only striated muscle cells but also adipocytes, neuron cells and smooth muscle cells. Previous studies have established in vitro mouse mesangial cells (MCs) to maintain the differentiated smooth muscle phenotype. MATERIALS AND METHODS The purpose of the present study was to clone bHLH proteins...
متن کاملRoles of the basic helix-loop-helix genes Hes1 and Hes5 in expansion of neural stem cells of the developing brain.
Neural stem cells, which differentiate into neurons and glia, are present in the ventricular zone of the embryonal brain. The precise mechanism by which neural stem cells are maintained during embryogenesis remains to be determined. Here, we found that transient misexpression of the basic helix-loop-helix genes Hes1 and Hes5 keeps embryonal telencephalic cells undifferentiated although they hav...
متن کاملMultiple basic helix-loop-helix proteins regulate expression of the ENO1 gene of Saccharomyces cerevisiae.
The basic helix-loop-helix (bHLH) eukaryotic transcription factors have the ability to form multiple dimer combinations. This property, together with limited DNA-binding specificity for the E box (CANNTG), makes them ideally suited for combinatorial control of gene expression. We tested the ability of all nine Saccharomyces cerevisiae bHLH proteins to regulate the enolase-encoding gene ENO1. EN...
متن کاملThe Basic/Helix-Loop-Helix Protein Family in Gossypium: Reference Genes and Their Evolution during Tetraploidization
Basic/helix-loop-helix (bHLH) proteins comprise one of the largest transcription factor families and play important roles in diverse cellular and molecular processes. Comprehensive analyses of the composition and evolution of the bHLH family in cotton are essential to elucidate their functions and the molecular basis of cotton development. By searching bHLH homologous genes in sequenced diploid...
