Tricarboxylic Acid Cycle Metabolite-Coordinated Biohydrogels Augment Cranial Bone Regeneration Through Neutrophil-Stimulated MSCs Recruitment and Histone Acetylation-Mediated Osteogenesis [RNA-Seq]

Project description:Cranial bone defect is a major clinical challenge that increases the life burden of patients. Tricarboxylic acid (TCA) cycle metabolites have recently drawn considerable attention in the field of bone tissue regeneration due to their bio-safety, low cost, structural stability, and effectiveness. However, the development of TCA cycle metabolite-modified biomimetic grafts for skull bone regeneration via a facile and general approach remains lacking. Moreover, the mechanism underlying the release of TCA cycle metabolites from biomaterials in immune responses and mesenchymal stem cells (MSCs) fate (migration and differentiation) remain unknown. Herein, inspired by the Hofmeister effects, we developed a series of TCA metabolite (in the form of sodium salt)-coordinated biomimetic hydrogels (CGG) with strong mechanical and anti-swelling performances. Importantly, the sodium citrate (Na3Cit)-treated CGG hydrogels (CGG-Cit) with the highest mechanical modulus and strength significantly promoted skull bone regeneration in rats and mice. Mechanistically, using a transgenic mouse model, bulk RNA sequencing, and single-cell RNA sequencing, we demonstrated that CGG-Cit promotes Gli1+ MSCs migration via neutrophil-secreted OSM. Our results also indicate that CGG-Cit improved osteogenesis via enhanced H3K9ac modification on osteogenic master genes. Taken together, the immune microenvironments and MSCs fate-regulated biomimetic hydrogels developed herein represent a highly efficient and facile approach toward skull bone tissue regeneration with great potential for bench-to-bedside translation.

Osteogenesis Chip-Seq

Project description:Bone development and repair depends on the differentiation of mesenchymal stem cells (MSCs) into osteoblasts. MSCs can be differentiated towards osteoblasts in vitro, making these cells a convenient tool for investigation of osteogenesis. Molecular characterization of this process is relevant for the application of MSCs in skeletal regenerative medicine, and for understanding the deregulation of osteogenesis in bone disease. Cellular differentiation is driven by highly regulated changes in gene expression, which at the level of transcription is associated with DNA binding of transcriptional regulators and local changes in chromatin landscape. By sequencing of RNA (RNA-Seq) and immunoprecipitated chromatin (ChIP-Seq) we have characterized gene expression, histone modification changes and DNA binding of the bone master regulator RUNX2 in osteogenic differentiation. Data from the RNA-Seq experiment has also been deposited at ArrayExpress under accession number E-MTAB-1829 (https://www.ebi.ac.uk/arrayexpress/experiments/E-MTAB-1829/).

Cranial Irradiation Impairs Juvenile Social Behavior and Modulates Hippocampal Physiology

Project description:Cranial and craniospinal irradiation are the oldest central nervous system prophylaxis treatments considered for pediatric patients with lymphoblastic leukemia (ALL). However, survivors of childhood ALL that received cranial radiotherapy are at increased risk for deficits in neurocognitive skills. The continuous and dynamic response of normal tissue after irradiation has been identified as one of the causative factors for cognitive changes after cranial radiation therapy. The aim of our study was to investigate the radiation effects on social behavior and neuronal morphology in the hippocampus of adult mice. Twenty-one-day-old male C57BL/6 mice were irradiated with the small-animal radiation research platform (SARRP). Animals were given a single 10-Gy dose of radiation of X-ray cranial radiation. One month following irradiation, animals underwent behavioral testing in the Three-Chamber Sociability paradigm. Radiation affected social discrimination during the third stage eliciting an inability to discriminate between the familiar and stranger mouse, while sham successfully spent more time exploring the novel stranger. Proteomic analysis revealed dysregulation of metabolic and signaling pathways associated with neurocognitive dysfunction such as mitochondrial dysfunction, Rac 1 signaling, and synaptogenesis signaling. We observed significant decreases in mushroom spine density in the Cornu Ammonis 2 of the hippocampus, which is associated sociability processing.
