Project description:The Inhibitor of the NFkB, IkBa, is the main regulator of the NFkB pathway. Our data has demonstrated that there is an alternative function for IkBa in the chromatin that affects HOX and other developmental genes. Keywords: CHIP-chip
Project description:The activation of NFkB pathway is commonly observed in many neurodegenerative disease and contributes to the disease pathogenesis. However, with hundreds of target genes expressed in the brain, the mechanism of NFkB signaling transduction pathway is bearly understood. We were interested in revealing the downstream mediators of NFkB in the brain and chose the IkBa-dificient model as our tool. IkBa is the essential negative regulator of NFkB activity and deletioon of IkBa induced NFkB hyperactivation. We used Nestin-Cre to conditionally knockout IkBa in the brain cells of neural lineage and performed the microarray to give us candidate genes.

We used Nestin-Cre to conditionally knockout IkBa in the brain cells of neural lineage and performed the microarray to give us candidate genes. Mouse hippocampi were dissected from 3 pairs of 2-3 month old IkBa brain-specific knockout animals and their littermate controls and used for RNA extraction and subsequent microarray assay

Our data has demonstrated that there is an alternative function for IkBa in the chromatin that affects HOX and other developmental genes. Keywords: CHIP-chip Chip-on-chip analysis has demonstrated that IkBa associates to the promoters of several genes. Chromatin fragments were obtained from NIH-3T3 cells and precipitated with 3 different IkBa comercial antibodies (raised in mouse, goat and rabbit), and fold enrichment was compared to input.
