Project description:Inflammation is a key component of pathological angiogenesis. Here we induce cornea neovascularisation using sutures placed into the cornea, and sutures are removed to induce a regression phase. We used whole transcriptome microarray to monitor gene expression profies of several genes

Age-dependent DNA methylation characterization of the rat supraoptic nucleus (Methylation)

Project description:Our prior studies indicat age-dependent contralateral axonal sprouting following unilateral lesion of magnocellular neurons in the supraoptic nucleus. We performed Oxford Nanopore sequencing of the rat supraoptic nucleus to determine changes in DNA methylation with age.

SSH-PCR dehydrated supraoptic nucleus

Project description:The magnocellullar neurons (MCNs) of the supraoptic nucleus (SON) of the hypothalamus are the principle source of the neuropeptide hormone vasopressin (VP), which has a crucial role in osmoregulation. Physiological activation of the SON by dehydration results is a massive release of VP from stores in posterior pituitary axon terminals into the general circulation. By binding to V2-type receptors located in the kidney, VP decrease the amount of water lost in urine. Osmotic activation of the SON is accompanied by a dramatic morphological and functional remodelling. We have sought to understand the mechanistic basis of this plasticity in terms of the differential expression of genes. To identify such genes, we adopted a completely unbiased and global approach based on Suppressive Subtractive Hybridisation-Polymerase Chain Reaction (SSH-PCR) Using this method, we generated a library of clones putatively differentially expressed in control vs dehydrated SON. In order to rapidly screen this library, 1152 of these clones were subjected to microarray analysis, resulting in the identification of 459 differentially expressed clones, 56 of which were sequenced. Many of these clones are expressed sequences that are new to science. Four of these were shown by in situ hybridisation (ISH) to be significantly up- or down-regulated in the SON following dehydration. These genes may represent novel effectors or mediators of SON physiological remodelling. 4 chips were hybridised with control SON and compared to 4 chips hybridised with dehydrated SON
