Abstract:
p53 protein isoform expression has been found to correlate with prognosis and chemotherapy response in acute myeloid leukemia (AML). We aimed to investigate how p53 protein isoforms are modulated during epigenetic differentiation therapy in AML, and if p53 isoform expression could be a potential biomarker for predicting a response to this treatment. p53 full-length (FL), p53β and p53γ protein isoforms were analyzed by 1D and 2D gel immunoblots in AML cell lines, primary AML cells from untreated patients and AML cells from patients before and after treatment with valproic acid (VPA), all-trans

Abstract:
Abstract Canonical p53-activated pathways can influence a microenvironment that promotes antitumor immune surveillance via tumor-associated macrophages (TAMs). We examined whether p53 activity in the tumor microenvironment (TME) influences antitumor immunity and show that p53 signaling induced pharmacologically with APR-246 (eprenetapopt) can augment the efficacy of immune checkpoint blockade (ICB) in preclinical models, a strategy that is also being tested in patients (NCT04383938). We first investigated the effects of combining APR-246 with ICB in wildtype C57BL6 (B6) mice bearing syngeneic

Abstract:
Acute myeloid leukemia (AML) is a heterogeneous disease that develops within a complex microenvironment. Reciprocal interactions between the bone marrow mesenchymal stem/stromal cells (BM-MSCs) and AML cells can promote AML progression and resistance to chemotherapy (Jacamo et al., 2014). We have recently reported that BM-MSCs derived from AML patients (n=103) highly express p53 and p21 compared to their normal counterparts (n=73 p<0.0001) (Hematologica, 2018). To assess the function of p53 in BM-MSCs, we generated traceable lineage specific mouse models targeting Mdm2 or Trp53 alleles

Abstract:
Abstract Acute myeloid leukemia (AML) is a genetically heterogeneous malignancy characterized by bone marrow infiltration of abnormally proliferating leukemic blasts which results in fatal anemia, bleeding and infectious complications due to compromised normal hematopoiesis. Patients with complete remission (CR) but incomplete blood cell count recovery (CRi) have significantly shorter survival compared to CR patients. Although there is a correlation between CRi and minimal residual disease (MRD), the two variables were shown to be independent risk factors for relapse development (1). The mecha

Abstract:
Abstract Bladder cancer (BCa) represents the fourth most common cancer in men with a poor patient prognosis for advanced disease. About 75% of patients present non-muscle invasive BCa (NMIBC) and 25% present muscle invasive BCa (MIBC) or metastatic disease. Although BCG immunotherapy is a common treatment of BCa, the dynamics of immune cell infiltration and its relevance for disease outcome are still not well understood. We took advantage of a genetic based mouse model of MIBC to obtain a profound understanding of the immune contexture over tumor development. P53Fl/Fl/PTENFl/Fl mice were injec

Abstract:
Abstract Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer and the leading cause of cancer-related deaths. The canonical NF-κB pathway displays critical functions in the development of PDAC. However, the relationship between the non-canonical NF-κB pathway and PDAC is still obscure. Here, we analyzed the role of the non-canonical NF-κB signaling in precancerous lesions and PDAC development by deleting NF-κB inducing kinase (NIK), an essential kinase for the activation of the non-canonical pathway. We used KC mice (Pdx1-cre/LSL-KrasG12D) that develop pancreati

Abstract Elevated levels of Interleukin 22 (IL-22) and its receptor (IL-22R) are associated with poor prognosis in pancreatic ductal adenocarcinoma (PDAC) and the underlying mechanism is currently unknown. Our aim is to investigate the role of the IL-22 axis in PDAC initiation and progression. Impact of IL-22 on tumor initiation was assayed by subcutaneous and intravenous inoculation of PDAC cells into wild-type and IL-22−/− mice. The PKCY (Pdx1-Cre; KrasG12D; p53fl/+; RosaYFP) model of pancreas cancer was used to study the in-vivo presence and significance of IL-22 in spontaneous tumors. Resu

Abstract:
Abstract Diffuse intrinsic pontine glioma (DIPG) is an incurable brain tumor that arises in the pons of children. Recent studies using single cell RNA-seq and enhancer analysis of DIPG tumor cells, together with analysis of the developing human pons, strongly suggest that an oligodendrocyte progenitor cell is the most likely cell-of-origin for DIPG. Here we describe a novel mouse model by expressing PDGF-B, with H3.3K27M or H3.3 wild-type in Olig2-expressing progenitors via injection into the 4th ventricle using Olig2-tva-cre;p53fl/fl mice.

Abstract:
The TP53 tumour suppressor gene encodes for p53 protein which is the frequently altered gene in most of the cancers. p53 protein is activated in response to different stresses and plays major role in maintaining genome integrity by regulating cell cycle and cell survival. It is known that p53 has twelve isoforms generated using alternate splicing, alternate promoters and translation initiation sites. Out of these isoforms ∆40p53 (also known as ∆N-p53/p47) is the only translational isoform of p53, produced from the same mRNA by using an ‘internal ribosome entry site’ (IRES). From our laboratory
