Analysis of genes regulated by Akirin and Brahma upon IMD pathway activation in drosophila S2 cells


ABSTRACT: This micro-array helps establishing the function of Akirin, a nuclear protein with unknown domains, a putative interacting partner, in the transcriptional regulation of the targets of Relish, a NF-kB factor required to fight Gram(-) bacteria infection in Drosophila melanogaster. S2 cells were knocked down for Relish, Akirin and immune-challenged by Calcium-phosphate transient transfection of dsRNA and over-expressing PGRP-LC vector. Positively transfected cells were sorted by co-expressed Tomato and RNA was purified and analysed by a micro-array

The network of NF-κB-dependent transcription that activates both pro- and anti-inflammatory genes in mammals is still unclear. As NF-κB factors are evolutionarily conserved, we used Drosophila to understand this network. The NF-κB transcription factor Relish activates effector gene expression following Gram-negative bacterial immune challenge. Here, we show, using a genome-wide approach, that the conserved nuclear protein Akirin is a NF-κB co-factor required for the activation of a subset of Rel  ...[more]
