Endogenous IFITM2 Involvement in Endocytosis to Regulate Neurogenesis

Project description:Purpose: To gain futher insight into how IFITM2 regulates the neurogenesis ,RNA-seq was used to analyze the genome-wide changes resulting from the cerebral cortices of E13 IFITM2 conditional knock out mice and littermate wild-type. Methods: Total RNA from E13 telencephalic tissue of wild-type(WT) and Ifitm2fl/fl;Nestin-Cre mice was extracted. Specifically, Agilent 2100 Bioanalyze was used to quality controlled and quantified. then, total RNA was converted to cDNA and bound the library. RNA-sequencing analysis was used by the Illumina HiSeq 6000 platform in Annoroad Genomics Approximately one thousand transcripts showed differential expression between the wild-type(WT) and Ifitm2fl/fl;Nestin-Cre mice brain cortex, with a fold change ≥1.5 and p value <0.05. These results reflected IFITM2 plays a role in cortex development. Conclusions: RNA-seq based transcriptome characterization would provide a overall understanding how IFITM2 gene regulated the neurogenesis.

Neuropeptides modulate local astrocytes to regulate adult hippocampal neural stem cells and neurogenesis

Project description:It has been well established that parvulbumin (PV) interneurons in the adult dentate gyrus (DG) regulate radial-glia like neural stem cells (rNSCs) through tonic GABA signaling. However, several major local interneuron subtypes co-release GABA and neuropeptides. Virtually nothing is known about whether and how endogenous neuropeptides regulate rNSCs. Here we demonstrate an unprecedented role of endogenous CCK in regulating rNSCs and hippocampal neurogenesis through distinctive states of the local astrocytes. Specifically, stimulating CCK release leads to increased Ca2+ transients in local astrocytes, and the subsequent astrocytic glutamate release promotes rNSC proliferation and neurogenesis via glutamate receptor mediated MAPK/ERK signaling cascade. In contrast, suppression of CCK synthesis switches resident astrocytes to a reactive state, which leads to decreased proliferation of rNSCs by regulating a gene network that negatively regulates rNSC proliferation. These findings have broad implications in multiple neuropathological conditions associated with altered CCK level, neuroinflammation, and impaired hippocampal neurogenesis.

Gene expression fingerprinting of ameloblasts shows changes in the endocytosis/cytoskeleton interface across stages.

Project description:We used RNA-seq to identify differentially expressed genes across ameloblast stages in rats. We found expression patterns of enamel matrix proteins, ion channels and transporters, and endocytosis regulators such as clathrin to match those found in previous experimental studies on ameloblasts. We hypothesized that ameloblasts change their endocytotic pathways as they progress from stage and stage, and we sought to identify novel patterns in expression of genes at the endocytosis/cytoskeleton interface. We found that maturation ameloblasts preferentially express synaptojanin 1 and intersectin 2 and secretory ameloblasts preferentially express Numb protein and amphiphysin. We also uncovered differential alternative splicing of ECI genes across ameloblast populations. In pointing to endocytotic genes hitherto unexplored in ameloblasts that also regulate cell morphology, this bioinformatics study suggests a mechanism by which cervical loop, secretory, and maturation ameloblasts switch modes of endocytosis in order to express genes that better suit the distinct morphology of each cell stage.

Genome-wide analysis of endocytosis inhibition on BMP-2 induced gene expression in C2C12 cells

Project description:Analysis of BMP-2 induced gene expression of C2C12 cells treated with the endocytosis inhibitor dynasore to identify gene expression profiles which are sensitive to endocytosis inhibition. Our data highlight the importance of endocytosis for transmission of an extracellular BMP-2 signal into the nucleus to activate a transcriptional gene network Total RNA obtained from C2C12 cells stimulated with BMP-2 together with the endocytosis inhibitor dynasore or DMSO as control compared to unstimulated cells treated with dynasore or DMSO alone.
