Project description:GW182 (Tnrc6a) is a key component of RISC (miRNA-Induced Silencing Complex) that plays a critical role in miRNA-mediated gene silencing. Here, we show that GW182 is expressed in airway multiciliated cells (MCCs), and that gene-trap disruption of GW182 leads to defective multicilia formation and downregulation of broad miRNA targets To investigate roles of GW182 in airway multiciliated cells (MCCc), we assessed changes in mRNA expression in E18.5 Tnrc6a mutant lungs using microarrays (Affymetrix).
Project description:The importance of unanchored Ub in innate immunity has been shown only for a limited number of unanchored Ub-interactors. We investigated what additional cellular factors interact with unanchored Ub and whether unanchored Ub plays a broader role in innate immunity. To identify unanchored Ub-interacting factors from murine lungs, we used His-tagged recombinant poly-Ub chains as bait. These chains were mixed with lung tissue lysates and protein complexes were isolated with Ni-NTA beads. Sample elutions were subjected to mass spectrometry (LC-MSMS) analysis.
Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility.
Project description:Deletion of Snx5 leads to respiratory failure in neonatal mice. Here we analyzed the effect of depleted SNX5 in a lung. We used expression microarray to compare between wild lungs and mutant lungs at E18.5 and E18.5 after air-breathing test.
