P63 ChIP-seq analysis comparing WT, TAp63-null, and DNp63-null primary murine keratinocytes

ABSTRACT: We performed a ChIP-seq analysis characterizing the p63 binding sites in primary keratinocytes obtained from E18.5 mice of 3 different genotypes (WT, TAp63-/-, and ΔNp63-/-). We aimed to identify the specific genomic regions bound by TAp63 and ΔNp63 in physiological conditions.

RNA-seq analysis comparing WT, TAp63-null, and DNp63-null primary murine keratinocytes

Project description:We performed an RNA-seq analysis characterizing expression profiles in primary keratinocytes obtained from E18.5 mice of 3 different genotypes (WT, TAp63-/-, and ΔNp63-/-). We aimed to identify the specific transcriptional target genes regulated by TAp63 and ΔNp63 in physiological conditions.

ChIP-seq analysis comparing WT, TAp63-/-, and ΔNp63-/- primary murine keratinocytes

Project description:The p53 family member TP63 encodes two sets of isoforms, TAp63 and ∆Np63 isoforms, which are characterized by different N-termini and have diverse biological functions in epidermal morphogenesis and in cancer. In the skin, where their activities are best characterized, TAp63 prevents premature aging by regulating cellular senescence and genomic stability of stem cells, while ∆Np63 controls terminal differentiation of the basal cells in the epidermis. This functional diversity is surprising given that these isoforms share a high degree of similarity, including an identical DNA binding domain. To understand the mechanisms involved in the transcriptional programs leading to these diverse biological functions, we performed genome-wide analyses using p63-ChIP-seq and RNA-seq of TAp63-/- and ∆Np63-/- compared to wild-type primary mouse epidermal cells. Our data indicate that TAp63 and ∆Np63 recognize significantly different response elements on DNA and can physically and functionally interact with distinct transcription factors for the downstream regulation of their target genes. Our findings unveil previously uncharacterized transcriptomes activated by the p63 isoforms to regulate diverse biological functions in epidermal morphogenesis and homeostasis and cancer.

Late cornified envelope 1C (LCE1C) gene is a transcriptional target of TAp63.

Project description:As a member of the p53/p63/p73 family, p63 is a transcriptional regulator that induces apoptosis, cell cycle arrest, or senescence. TAp63 protein, a p53-like master transcriptional regulator, plays an essential role in epithelial development because p63-null mice are born alive but die shortly after birth due to developmental defects. However, its molecular mechanism remains elusive. We identified these phosphorylation sites during a search for the targets of Cyclin G-associated kinase (GAK) in vitro. LCE1C was drastically upregulated by doxycycline-dependent expression of Myc-TAp63 wild-type (WT) proteins, but not non-phosphorylatable Myc-TAp63-T46A/T281A (AA) proteins.

Transcription profiling of skin from p63 null and wild type mice to identify genes that are directly or indirectly regulated by p63.

Project description:In the absence of p63 expression, the epidermis fails to commit to stratification, resulting in aborted skin development. In this study, gene expression profiles of E18.5 p63 null and wt skin, were compared in an effort to identify genes that are directly or indirectly regulated by p63. Experiment Overall Design: E18.5 embryos were obtained from matings between p63 heterozygous mice. RNA was isolated from the skin of two p63 null and two wild type embryos.

Gene expression profiles induced by knockdown and overexpression of p63 variants in MCF-10A mammary epithelial cell line

Project description:p63 is critical for epithelial development yet little is known about the transcriptional programmes it regulates. The p63 transactivating (TA) isoforms contain an amino-terminal exon that encodes a p53-like transactivation domain, whereas ÎN-isoforms lack this domain but contain the common DNA binding domain (DBD), suggesting that TAp63 and ÎNp63 isoforms may have opposing functions. By characterising transcriptional changes and cellular effects following modulation of p63 expression, we have defined a vital role for p63 in cellular adhesion. Knockdown of p63 expression caused downregulation of cell adhesion-associated genes, cell detachment and anoikis in mammary epithelial cells and keratinocytes. Conversely, overexpression of the TAp63Î³ or ÎNp63Î± isoforms of p63 upregulated cell adhesion molecules, increased cellular adhesion and conferred resistance to anoikis. Total RNA was isolated 48 h after retroviral or adenoviral infection and was subjected to reverse transcription, labelling and hybridization. The knockdown samples were performed in duplicate with shRNA vector control, shRNA targetting all isoforms of p63 (shDBD) and shRNA targetting p63 isoforms containing the transactivating (TA) domains. The overexpression samples were performed in triplicate with vector control, overexpression of the ÎNp63Î± isoform, and overexpression of the TAp63Î³ isoforms.

Project description:We performed a smallRNA-Seq analysis comparing thymic lymphoma tissues from the p53-null (n=4) and ΔNp63Δ/Δ;p53-/- (n=3). Mice at 10 weeks of age were injected with either Ad-mCherry or Ad-CRE-mCherry to delete ΔNp63 in the thymic lmyphomas. We aimed to test by deleting the ΔNp63 in these p53-deficient tumors will mediate tumor regression and analyze the expression profile of the small RNAs

FANCD2 Activates Transcription of TAp63 and Suppresses Tumorigenesis

Project description:Fanconi Anemia (FA) is a rare genetic disorder characterized by an increased susceptibility to squamous cell cancers. Fifteen FA genes are known, and the encoded proteins cooperate in a common DNA repair pathway. A critical step is the monoubiquitination of the FANCD2 protein, and cells from most FA patients are deficient in this step. How monoubiquitinated FANCD2 suppresses squamous cell cancers is unknown. Here we show that Fancd2-deficient mice are prone to Ras oncogene-driven skin carcinogenesis, while Usp1-deficient mice, expressing elevated cellular levels of Fancd2-Ub, are resistant to skin tumors. Moreover, Fancd2-Ub activates the transcription of the tumor suppressor TAp63, thereby promoting cellular senescence and blocking skin tumorigenesis. For FA patients, the reduction of FANCD2-Ub and TAp63 protein levels may account for their susceptibility to squamous cell neoplasia. Taken together, Usp1 inhibition may be a useful strategy for upregulating TAp63 and preventing or treating squamous cell cancers in the general non-FA population.
