Kat2a regulates hippocampal memory formation [RNA-seq]

Project description:We sequenced mRNA from 24 samples extracted from mouse CA1 tissue to generate the first CA1-specific murine transcriptome and the first CA1-transcriptome in response to environmental novelty under normal and Kat2a-loss-of-function conditions. Samples were divded in 4 groups: A: Control naM-CM-/ve (n=6), B: control novelty-exposed (n=5), C: Kat2a cKO naM-CM-/ve (n=6), D: Kat2a cKO novelty-exposed (n=7). Pairwise comparisons for AvsB, AvsC, BvsD and CvsD were performed using DESeq2.

3D Bioprinted Models for Predicting Chemotherapy Response in Colorectal Cancer With/Without Liver Metastases

Project description:The therapeutic regimens of adjuvant and neoadjuvant chemotherapy for colorectal cancer (CRC) remain largely relied on clinical experience, and thus preclinical models are needed to guide individualized medicine. The investigators are going to establish 3D bioprinted CRC models and organoids from surgically resected tumor tissues of CRC patients with or without liver metastases. In vitro 3D models and organoids will be treated with the same chemotherapy drugs with the corresponding patients from whom the models are derived. The sensitivity of chemotherapy drugs will be tested in these two types of in vitro models, and the actual response to chemotherapy in patients will be evaluated. The predictive ability of 3D models for chemotherapy sensitivity in CRC patients will be compared with that of the organoids. This observational study will validate the potential value of 3D bioprinted tumor models in predicting the response to chemotherapy in CRC.

Distinct contributions of KAT2A histone acetyl-transferase complexes to human erythropoiesis

Project description:KAT2A is a histone acetyl-transferase involved in stabilization of transcriptional activity through acetylation of lysine residue 9 of Histone 3. Mouse knockout models suggest that Kat2a is dispensable for haematopoietic stem and progenitor cell activity, despite a central role in survival and maintenance of Acute Myekoid Leukaemia cells through block of differentiation. Herein, we investigate KAT2A activity in human cord blood haematopoiesis and identify a specific requirement in the establishment of the erythroid lineage. KAT2A is required for specification and survival of Erythroid-Megakaryocytic progenitors, with regulation of expression of the erythropoietin receptor (EPOR) gene, which participates in lineage commitment, as well as of later effector genes in the platelet and erythroid lineages. Early and late lineage roles can be distinctly attributed to the ATAC and SAGA complexes in which context KAT2A exerts its activity. ATAC is active earlier in erythroid lineage development and mediates MEP specification from HSC, whilst SAGA activity is required post-commitment, including in expression of haemoglobin genes. We thus position KAT2A as a novel regulator of human erythropoiesis and separate early and later effects in lineage development with complex specificity. This has implications for putative therapeutic targeting of KAT2A complexes in leukaemia.

Human KAT2A/B-acetylome MudPIT

Project description:Comprehensive identification of acetylated proteins targeted by the lysine acetyltransferases KAT2A (GCN5) and KAT2B (PCAF), in human cells. KAT2A/B-dependent acetylated proteins were identified by comparing acetylated proteins in whole cell extract of control cells and cells in which KAT2A and KAT2B were simultaneously knocked down. The identification of acetylated proteins was performed using an enrichment-free approach. In order to do so, while facing the challenge of identifying low abundant acetylated peptides within a complex sample mixture, we have screened acetylated peptides starting from a large amount of material, equivalent to 50ug of protein digest (maximum loading capacity of our analytical chromatographic column). By analysing such a large amount of peptides, the level of acetylated peptides was then increased and thus acetylated peptides became easily detectable by mass spectrometry, without the need for enrichment.

Divergent Functions of Histone Acetyltransferase Paralogs KAT2A and KAT2B in Keratinocyte Stemness and Differentiation

Project description:The mammalian epidermis undergoes constant renewal replenished by a pool of stem cells and terminal differentiation of their progeny. This is accompanied by changes in gene expression and morphology orchestrated, in part, by epigenetic modifiers. Here, we defined the role of histone acetyltransferase KAT2A in epidermal homeostasis and provided a comparative analysis that revealed key functional divergence with its paralogue, KAT2B. In contrast to KAT2B's reported function in epidermal differentiation, KAT2A supports the undifferentiated state in keratinocytes. RNA-seq analysis of KAT2A- and KAT2B- depleted keratinocytes revealed dysregulated epidermal differentiation. Depletion of KAT2A led to premature expression of epidermal differentiation genes in the absence of inductive signals, whilst loss of KAT2B delayed differentiation. KAT2A acetyltransferase activity was indispensable in regulating epidermal differentiation gene expression. The metazoan-specific N-terminus of KAT2A was also required to support its function in keratinocytes. We further showed that the interplay between KAT2A- and KAT2B- mediated regulation was important for normal cutaneous wound healing in vivo. Overall, these findings reveal a distinct mechanism in which keratinocytes utilize a pair of highly homologous histone acetyltransferases to support divergent functions in self-renewal and differentiation processes.
