Regulation of mouse lens fiber cell development and differentiation by the Maf gene.
Maf is a basic domain/leucine zipper domain protein originally identified as a proto-oncogene whose consensus target site in vitro, the T-MARE, is an extended version of an AP-1 site normally recognized by Fos and Jun. Maf and the closely related family members Neural retina leucine zipper (Nrl), L-Maf, and Krml1/MafB have been implicated in a wide variety of developmental and physiologic roles...
متن کاملRequirement for the c-Maf transcription factor in crystallin gene regulation and lens development.
The vertebrate lens is a tissue composed of terminally differentiated fiber cells and anterior lens epithelial cells. The abundant, preferential expression of the soluble proteins called crystallins creates a transparent, refractive index gradient in the lens. Several transcription factors such as Pax6, Sox1, and L-Maf have been shown to regulate lens development. Here we show that mice lacking...
متن کاملAnalysis of non-crystallin lens fiber cell gene expression in c-Maf -/- mice.
PURPOSE To examine the role of the c-Maf transcription factor in the regulation of non-crystallin lens fiber cell specific gene expression. METHODS Expression of lens fiber cell genes in c-Maf null mice was analyzed by immunohistochemical and RT-PCR methods. In addition, the effect of c-Maf on fiber cell gene promoter fragments was examined in co-transfection experiments. RESULTS Examinatio...
متن کاملThe Transcription Factor c-Maf Promotes the Differentiation of Follicular Helper T Cells
Follicular helper T cells (Tfh) have been identified as the primary cell subpopulation regulating B cell responses in germinal centers, thus supporting high-affinity antibody production. Among the transcription factors orchestrating Tfh cell differentiation and function, the role played by the proto-oncogene c-Maf remains poorly characterized. We report herein that selective loss of c-Maf expre...
متن کاملThe p53 transcription factor modulates microglia behavior through microRNA-dependent regulation of c-Maf.
Neuroinflammation occurs in acute and chronic CNS injury, including stroke, traumatic brain injury, and neurodegenerative diseases. Microglia are specialized resident myeloid cells that mediate CNS innate immune responses. Disease-relevant stimuli, such as reactive oxygen species (ROS), can influence microglia activation. Previously, we observed that p53, a ROS-responsive transcription factor, ...
