Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
p65-/-Ras cells show delayed tumor formation in SCID mice. However, after prolonged latency, tumor formation was observed from these mice. To understand the changes of NF-kB regulated genes before and after tumor formation, RNA from p65+/+Ras, p65+/+RasTumor, p65-/-Ras, p65-/-RasTumor cells were isolated and microarray were performed.

Description
Multiple transcription factors regulate B cell commitment, which coordinates with myeloiderythroid lineage differentiation. One such factor, NF-kB, has long been speculated to regulate early B cell development; however, this issue remains controversial. IKKa is required for splenic B cell maturation, but not for bone marrow (BM) B cell development. Here, we unexpectedly found defective BM B cell development and an increased myeloiderythroid lineages in kinase-dead IKKa (KA/KA) knock-in mice. Markedly increased cytosolic p100, an NF-kB2 inhibitory form, and reduced nuclear NF-kB p65, RelB, p50, and p52, as well as IKKa, was observed in KA/KA splenic and BM B cells. Several B- and myeloiderythroid-cell regulators, including Pax5, were deregulated in KA/KA BM B cells. Using fetal liver and BM congenic transplants, and IKKa deletion from early hematopoietic cells in mice, this defect was identified as B cell intrinsic and as an early event during hematopoiesis. Re-expression of IKKa, Pax5, or combined NF-kB molecules promoted B cell development, but repressed myeloiderythroid cell differentiation in KA/KA BM B cells. Together, these results demonstrate that IKKa regulates B-lineage commitment via combined canonical and noncanonical NF-kB transcriptional activity to target Pax5 expression during hematopoiesis.

Description
During neonatal development, skeletal muscle grows dramatically by myonuclei accretion to existing fibers and hypertophic growth of fibers with protein synthesis. Overall design: To understand molecular mechanism underlying neonatal muscle growth, we used RNAseq to profile the global program of gene expressions especially involved in myoblast fusion, migration, and muscle fiber growth by itself. We used two biological replicates for each time point.

Description
We found genetic deletion of IKK in mdx cardiomyocytes improved cardiac function and normalized calcium transients. We used microarrays to profile gene expression in hearts of mdx mice with intact IKK signaling and hearts of mdx mice with IKK-deficient cardiomyocytes to identify genes differentially regulated by NF-[kappa]B. signaling in dystrophic hearts.
