Project description:In order to identify targets for HDAC4, NRVM were infected with adenoviral vectors encoding beta-Galactosidase or Flag- HDAC4, and incubated in serum free or 10% fetal calf serum containing growth medium for 48 hrs. NRVM were infected with adenoviral vectors encoding beta-Galactosidase (control) or Flag- HDAC4 (experiment), and incubated in serum free or 10% fetal calf serum containing growth medium for 48 hrs. 2 biological samples of each condition were analyzed.
Project description:Suz12(Bgal/Bgal) ESCs express a truncated form of Suz12 fused to Beta-galactosidase. These cells maintain a reduced level of H3K27me3 despite this mutation to a core component of PRC2, unlike Eed-/- ESCs whose H3K27me3 is ablated.
Project description:Data on multiplex HT-SEC with online CD-MS detection. Data is included for beta galactosidase alone, in a mixture with GroEL, and for a high mass enriched E. coli lysate mixture
Project description:Lgr5+ cells isolated from liver organoids act as bipotent liver progenitors. Beta-galactosidase (beta-gal)-expressing cells appear in injured livers of Lgr5-LacZ mice, however, their origin and identity has remained controversial. Here we sought to clarify this issue. The majority of beta-gal+ cells emerged in pericentral regions of the liver lobule. Lineage tracing demonstrated that beta-gal+ cells did not originate from hepatocytes or cholangiocytes. Beta-gal+ cells were negative for hepatocyte and cholangiocyte markers; but positive for Kupffer cell markers. Transcriptome analysis revealed the expression of endogenous beta-galactosidase Glb1 and genes characteristic of TREM2+ macrophages that may regulate stem cell maintenance. We were not able to detect the expression of the Lgr5-LacZ transgene and concluded that the transgene was silenced.
Project description:Wnt signal transduction during an immune response is involved in the establishment of functional CD8 T cell memory P14 ConductinLacZ CD8 T cells (CD45.2) were transferred in CD45.1+.2+ recipient mice. The day after, recipients were infected with 200pfu LCMV WE. At day 8 after infection, cells from spleen and lymph nodes were harvested, magnetically enriched for CD8 T cells, loaded with the beta-galactosidase substrate (FDG) and sorted as 7AAD-negative CD45.- negative, beta-galactosidase positive versus negative cells.
Project description:Suz12(Bgal/Bgal) ESCs express a truncated form of Suz12 fused to Beta-galactosidase. These cells maintain a reduced level of H3K27me3 despite this mutation to a core component of PRC2, unlike Eed-/- ESCs whose H3K27me3 is ablated. Two ESC lines mutant in genes of core components of Polycomb Repressive Complex 2 were assessed for H3K27me3 by ChIP-seq, as compared to a wild type ESC line.

P14 CD8 T cells were sorted at day 8 after LCMV infection according to LacZ activity for RNA extraction and hybridization on Affymetrix microarrays.
Project description:Suz12(Bgal/Bgal) ESCs express a truncated form of Suz12 fused to Beta-galactosidase. These cells maintain a reduced level of H3K27me3 despite this mutation to a core component of PRC2, unlike Eed-/- ESCs whose H3K27me3 is ablated. This data shows the concomitant changes in H3K4me3 levels in these cells.
Project description:EGFR inhibitor Erlotinib treatment can induce NHBE into profound cell cycle arrest that include senescence and quiescence. Because senescent cells feature high senescence assocaited-beta-galactosidase(SA-β-gal) activty, which has been used as marker for FACS based collection of senescent and quiescent cells, respectively.
Project description:The purpose of this study was to study the biological consequences of inhibiting acid beta-galactosidase with the use of conduritol b epoxide, which serves as a chemical model of Gaucher disease
