Effect of c-Maf mutation on Mafb-GFP-positive FACS-purified cells in the E12.5 mouse gonad

ABSTRACT: Morphogenesis of the gonad requires cell-cell adhesion changes between diverse cell types. In the Drosophila gonad, the gene traffic jam regulates cell adhesion changes required for gonad formation and germ cell development (Li et al., 2003. Nature Cell Biol). To determine if the mammalian homologs of traffic jam in mammals, c-Maf and Mafb, also play a role in the transcription regulation of cell adhesion molecules in the mouse gonad, we performed a microarray analysis of FACS-purified Mafb-GFP-positive cells in E12.5 male control and c-Maf/Mafb mutant gonads. We used microarrays to determine genes affected by c-Maf mutation in E12.5 mouse gonad/mesonephros interstitial cells and macrophages E12.5 XY control (c-Maf+/-;Mafb-GFP+/-) and c-mutant (c-Maf-/-;Mafb-GFP+/-) gonad/interstitial interstitial cells and macrophages were obtained by FACS sorting of Mafb-GFP-positive cells. RNA was extracted for subsequent hybridization on Affymetrix microarrays.

Gene expression profile of E18.5 epidermis from WT and MafB KO mice

Project description:MafB is a member of the Maf family of bZip transcription factor and plays important roles in the developmental processes of various tissues, as well as in cell-type specific gene expression. MafB is expressed in differentiating keratinocytes in mice and is transcriptionally up-regulated upon human keratinocyte differentiation in vitro. In MafB-deficient mice, epidermal differentiation is partially impaired and the cornified layer is thinner. To gain insights into more detailed molecular mechanisms of MafB regulation of epidermal development, we performed microarray analysis of mRNAs isolated from dorsal skin epidermis of MafB-/- and wild-type mice at E18.5. Epidermis was separated from dorsal skin tissues of E18.5 mouse embryos (MafB-/- and WT) by Dispase (Life Technologies) treatment. Total RNA was isolated using Trizol reagent (Life Technologies), purified using an RNeasy mini kit (Qiagen), and subjected to microarray analysis.

The deubiquitinase USP7 stabilizes Maf proteins to promote myeloma cell survival

Project description:USP7, as a deubiquitination enzyme, controls ubiquitination and stability of Maf family proteins. USP7 promotes Maf transcriptional activity. Moreover, USP7 is overexpressed in multiple myeloma cells and its expression level is negatively correlated to the survival of myeloma patients.

Gene expression profiles of the E15.5 developing podocyte (GUDMAP Series_id: 33)

Project description:The long term objective is to create an encyclopedia of the expression levels of all genes in multiple components of the developing kidney. The central thesis is straightforward. The combination of fluorescent activated cell sorting (FACS) plus microarray analysis offers a powerful, efficient and effective method for the creation of a global gene expression atlas of the developing kidney. Microarrays with essentially complete genome coverage can be used to quantitate expression levels of every gene in FACS isolated components of the developing kidney. The ensuing rapid read-out provides an expression atlas that is more sensitive, more economical and more complete than would be possible by in situ hybridizations alone. MafB-GFP BAC transgenic mice were utilized to isolate the podocyte cells from the developing embryonic kidneys. Podocyte cells were isolated from the kidney using trypsinization and FACS. RNA was isolated and the gene expression profiles were determined by microarrays.

Roles of Mafb and c-Maf in MGE-derived pallial interneuron development and maturation

Project description:We utilized single-cell RNA-sequencing to identify candidate genetic targets of Mafb and c-Maf in the MGE-lineage using Nkx2.1-Cre generated neonatal wildtype (WT) and conditional Mafb/c-Maf double deletion mutant (cDKO) animals. We identified genes that likely contribute to Maf cDKO's phenotypes, which include preferential parvalbumin interneuron loss, overproduction of hippocampal interneurons and neurite outgrowth defects.

Non adherent macrophage of mafb null and WT

Project description:MafB is a member of the large Maf family of transcription factors that share similar basic region/leucine zipper DNA binding motifs and N-terminal activation domains.Although it is well known that MafB is specifically expressed in macrophages, characterization of the null mutant phenotype in these tissues has not been previously reported. To investigate suspected MafB functions macrophages, we generated mafB/green fluorescent protein (GFP) knock-in null mutant mice. MafB deficiency was found to dramatically suppress F4/80 expression in nonadherent macrophages. To investigate detail function of MafB in nonadherent macrophages, we performed microarray analysis. Macrophages were derived from day 14.5 fetal livers of mafB- /- and WT mice. Suspensions of single fetal liver cells were prepared by mechanical disruption . A total of 106 cells in suspension were centrifuged at 1,200 rpm for 5 min, and the cell pellet was resuspended in Dulbeccoâs modified Eagleâs medium supplemented with 10% fetal calf serum (heat inactivated), streptomycin and penicillin (100 units/ml), and macrophage colony-stimulating factor (M-CSF) (10 ng/ml) and then seeded either onto a nonadhesive dishes coated with hydrophilic polymers (Hydrocell; Cell Seed, Tokyo). The culture medium was not changed throughout the experiment. M-CSF (final concentration, 10 ng/ml) was added every day from day 4 onwards. One, 2, 4, and 6 days after seeding, the cells were harvested and analyzed by flow cytometry. After 6 day culture, macrophages of Mafb-/- and WT were use microarray analysis .
