Expression data from K5-IKKbeta transgenic mouse skin

ABSTRACT: IKKbeta is a subunit of the IkB kinase (IKK) complex required for NF-kB activation in response to pro-inflammatory signals. NF-kB regulates the expression of many genes involved in inflammation, immunity and apoptosis, and also controls cell proliferation and differentiation in different tissues; however, its function in skin physiopathology remains controversial. We here report the alterations caused by increased IKKbeta activity in basal cells of the skin of transgenic mice. Transgenic mice which express the IKKbeta gene under the control of the keratin K5 regulatory elements were generated. We analyzed back skins from wildtype and transgenic animals. Each individual array has RNA from three different mice of the same genotype.

Role of NF-kB in aging

Project description:To address the role of NF-kB in aging in vivo, we utilized a well-characterized system that allows inducible and site-specific inhibition of NF-kB activity in murine skin. The hormone binding domain of the mutant estrogen receptor that is responsive to 4-hydroxytamoxifen (4-OHT) was fused to a mutant of p50 (IDNkB, inducible dominant negative NF-kB) that dimerizes with other NF-kB subunits but is unable to bind DNA, thus dominantly inhibiting NF-kB activity. Expression was driven within the basal layer of murine epidermis by the keratin 14 promoter in transgenic mice. To test whether NF-kB activity is required to maintain age-associated gene expression, we applied topical 4-OHT and ethanol vehicle (EtOH) for two weeks to the right (R) and left (L) dorsal flanks, respectively, of chronologically aged transgenic mice (O, 18-23 months). Young transgenic mice (Y, 1 month) were treated in parallel as control. Skin samples were harvested and analyzed for gene expression using mouse cDNA microarrays containing 35,217 elements, representing 18,880 unique genes. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Keywords: Logical Set Computed

Expression data from small intestine of NFKBIA-KO mice versus wild type

Project description:The IkB-Kinase (IKK)-NF-kB signaling pathway plays a multifaceted role in Inflammatory Bowel Disease: One the one hand it protects cells from apoptosis, but on the other, it activates transcription of numerous inflammatory cytokines and chemokines. To examine the role of constitutive NF-kB signaling in intestinal epithelium cells (IEC), we generated a mouse model with a tissue-specific knockout of the direct inhibitor of NF-kB, IkBα. We demonstrate that in IκBαIEC-KO mice, constitutive activation of NF-kB in epithelium leads to abnormal intestinal development, enlarged peyer’s patches, loss of Paneth cells, and spontaneous inflammation. We performed expression analysis of IκBαIEC-KO mice compared to wildtype by using the Affymetrix array Clariom S mouse.

NFkB dependent gene expression in a Mdr2-KO hepatocellular carcinoma (HCC) mouse model using a IkB-Superrepressor

Project description:This study aims on the identification of the NF-kB dependent gene regulatory network during inflammation-associated liver carcinogenesis using the well-established Mdr2 knockout mouse model. We could identify 367 differentially expressed genes comparing expression profiles of tumor samples from Mdr2-KO mice to tumor samples derived from mice with an additional hepatocyte specific expression of an IkB-superrepressor. This IkB-superrepresser is undegradable upon ubiquitinylation initialized by Ikk dependent phosphorylation and therefore impedes NFkB activity.

Analysis of temporal mRNA expression changes in cultured keratinocytes from Casp-8F/–K5-Cre and Casp-8F/+K5-Cre mice

Project description:Expression of enzymatically inactive caspase-8, or deletion of caspase-8 from basal epidermal keratinocytes, triggers chronic skin inflammation in mice. Unlike similar inflammation resulting from arrest of NF-kB activation in the epidermal cells, the effect induced by caspase-8 deficiency did not depend on TNF, IL1, dermal macrophage function, or expression of the Toll-like receptor adapter proteins MyD88 or TRIF. Both interferon regulatory factor (IRF)3 and TANK-binding kinase were constitutively phosphorylated in the caspase-8-deficient epidermis, and knockdown of IRF3 in the epidermis-derived cells from these mice abolished the expression of upregulated genes. Temporal and spatial analyses of the alterations in gene expression that result from caspase-8 deficiency reveal that the changes are initiated before birth, around the time that cornification develops, and occur mainly in the suprabasal layer. Finally, we found that caspase-8-deficient keratinocytes display an enhanced response to gene activation by transfected DNA. Our findings suggest that an enhanced response to endogenous activators of IRF3 in the epidermis, presumably generated in association with keratinocyte differentiation, contributes to the skin inflammatory process triggered by caspase-8 deficiency.

AhmedMobeen2021 - NF-kB Activation Model

Project description:NF-kappaB Activation Model includes the activation of both NFKB1:RELA and NFKB2:RELB for Canonical and Non-Canonical Pathway respectively. The model includes the pathway model integrated with post-translational modifications of NF-kB subunits that regulate the NFKB1:RELA and NFKB2:RELB activity. The processes that are regulated by NF-kB pathway can be monitored through following readouts NFKB1:RELA Activity, NFKB2:RELB Activity, Degraded RelA, Degraded RelB, Degraded IkB, Degraded NIK, Apoptosis, Tumour, Antiviral Activity, B Cell Growth and Cell Migration. However, last 5 processes above are also influenced by other pathways too, therefore while making predictions, caution has to be exercised.
