Project description:ChIP-seq was performed in BIN-67, BIN-67 p53ko, BIN-67 with SMARCA4 restoration and BIN-67 p53ko cells with SMARCA4 restoration to assess the impact of SMARCA4 and p53 on the pull downs of p300, H3K27ac, p53, HDAC1 and HDAC2.
Project description:We aim to test how SMARCA4 restoration impacts p300 occupancy distribution. To this aim we generated ChIP-seq samples in BIN-67 with or without A-485 treatment (1 μM, 24h), as a proxy for p300 acetylatransferase inhibition, and BIN-67 with inducible SMARCA4 restoration (1 μg/ml Doxycycline for 24h). We pulled down p300 and H3K27ac as a marker for p300 acetyltransferase activity on the chromatin.
Project description:Morphine causes microbial dysbiosis. In this study we focused on restoration of native microbiota in morphine treated mice and looked at the extent of restoration and immunological consequences of this restoration. Fecal transplant has been successfully used clinically, especially for treating C. difficile infection2528. With our expanding knowledge of the central role of microbiome in maintenance of host immune homeostasis17, fecal transplant is gaining importance as a therapy for indications resulting from microbial dysbiosis. There is a major difference between fecal transplant being used for the treatment of C. difficile infection and the conditions described in our studies. The former strategy is based on the argument that microbial dysbiosis caused by disproportionate overgrowth of a pathobiont can be out-competed by re-introducing the missing flora by way of a normal microbiome transplant. This strategy is independent of host factors and systemic effects on the microbial composition. Here, we show that microbial dysbiosis caused due to morphine can be reversed by transplantation of microbiota from the placebo-treated animals.
Project description:The great tit is a widely studied passerine bird species in ecology that, in the past decades, has provided important insights into speciation, phenology, behavior and microevolution. After completion of the great tit genome sequence, a customized high density 650k SNP array was developed enabling more detailed genomic studies in this species.
