Deciphering the Functions of Ets2, Pten and P53 in Stromal Fibroblasts in Multiple
Deciphering the Functions of Ets2, Pten and p53 in Stromal Fibroblasts in Multiple Breast Cancer Models DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Julie Wallace Graduate Program in Molecular, Cellular and Developmental Biology The Ohio State University 2013 Dissertation Committee: Michael C. Ostrowski, PhD, Advisor Gustavo Leone, PhD Denis Guttridge, PhD Dawn Chandler, PhD Copyright by Julie Wallace 2013 Abstract Breast cancer is the second most common cancer in American women, and is also the second leading cause of cancer death in women. It is estimated that nearly a quarter of a million new cases of invasive breast cancer will be diagnosed in women in the United States this year, and approximately 40,000 of these women will die from breast cancer. Although death rates have been on the decline for the past decade, there is still much we need to learn about this disease to improve prevention, detection and treatment strategies. The majority of early studies have focused on the malignant tumor cells themselves, and much has been learned concerning mutations, amplifications and other genetic and epigenetic alterations of these cells. However more recent work has acknowledged the strong influence of tumor stroma on the initiation, progression and recurrence of cancer. Under normal conditions this stroma has been shown to have protective effects against tumorigenesis, however the transformation of tumor cells manipulates this surrounding environment to actually promote malignancy. Fibroblasts in particular make up a significant portion of this stroma, and have been shown to impact various aspects of tumor cell biology. -

Identification of Chebulinic Acid As a Dual Targeting Inhibitor of Protein
Bioorganic Chemistry 90 (2019) 103087 Contents lists available at ScienceDirect Bioorganic Chemistry journal homepage: www.elsevier.com/locate/bioorg Short communication Identification of chebulinic acid as a dual targeting inhibitor of protein T tyrosine phosphatases relevant to insulin resistance Sun-Young Yoona,1, Hyo Jin Kangb,1, Dohee Ahna, Ji Young Hwanga, Se Jeong Kwona, ⁎ Sang J. Chunga, a School of Pharmacy, Sungkyunkwan University, Suwon 16419, Republic of Korea b Department of Chemistry, Dongguk University, Seoul 100-715, Republic of Korea ARTICLE INFO ABSTRACT Keywords: Natural products as antidiabetic agents have been shown to stimulate insulin signaling via the inhibition of the Protein tyrosine phosphatases (PTPs) protein tyrosine phosphatases relevant to insulin resistance. Previously, we have identified PTPN9 and DUSP9 as Chebulinic acid potential antidiabetic targets and a multi-targeting natural product thereof. In this study, knockdown of PTPN11 Type 2 diabetes increased AMPK phosphorylation in differentiated C2C12 muscle cells by 3.8 fold, indicating that PTPN11 could Glucose-uptake be an antidiabetic target. Screening of a library of 658 natural products against PTPN9, DUSP9, or PTPN11 PTPN9 identified chebulinic acid (CA) as a strong allosteric inhibitor with a slow cooperative binding toPTPN9 PTPN11 (IC50 = 34 nM) and PTPN11 (IC50 = 37 nM), suggesting that it would be a potential antidiabetic candidate. Furthermore, CA stimulated glucose uptake and resulted in increased AMP-activated protein kinase (AMPK) phosphorylation. Taken together, we demonstrated that CA increased glucose uptake as a dual inhibitor of PTPN9 and PTPN11 through activation of the AMPK signaling pathway. These results strongly suggest that CA could be used as a potential therapeutic candidate for the treatment of type 2 diabetes. -

Genetic Association of PTPN22 Polymorphisms with Autoimmune
www.nature.com/scientificreports OPEN Genetic Association of PTPN22 Polymorphisms with Autoimmune Hepatitis and Primary Biliary Received: 08 April 2016 Accepted: 23 June 2016 Cholangitis in Japan Published: 11 July 2016 Takeji Umemura1, Satoru Joshita1, Tomoo Yamazaki1, Michiharu Komatsu1, Yoshihiko Katsuyama2, Kaname Yoshizawa3, Eiji Tanaka1 & Masao Ota4 Autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) are liver-specific autoimmune conditions that are characterized by chronic hepatic damage and often lead to cirrhosis and hepatic failure. Specifically, theprotein tyrosine phosphatase N22 (PTPN22) gene encodes the lymphoid protein tyrosine phosphatase, which acts as a negative regulator of T-cell receptor signaling. A missense single nucleotide polymorphism (SNP) (rs2476601) in PTPN22 has been linked to numerous autoimmune diseases in Caucasians. In the present series, nine SNPs in the PTPN22 gene were analyzed in 166 patients with AIH, 262 patients with PBC, and 322 healthy controls in the Japanese population using TaqMan assays. Although the functional rs3996649 and rs2476601 were non-polymorphic in all subject groups, the frequencies of the minor alleles at rs1217412, rs1217388, rs1217407, and rs2488458 were significantly decreased in AIH patients as compared with controls (allPc < 0.05). There were no significant relationships with PTPN22 SNPs in PBC patients. Interestingly, the AAGTCCC haplotype was significantly associated with resistance to both AIH (odds ratio [OR] = 0.58, P = 0.0067) and PBC (OR = 0.58, P = 0.0048). SNPs in the PTPN22 gene may therefore play key roles in the genetic resistance to autoimmune liver disease in the Japanese. Autoimmune diseases are characterized by an aberrant immune response to self-antigens. Although genetic factors contribute to disease susceptibility and severity, the mechanisms of disease initiation and persis- tence remain poorly understood. -

The Expression Patterns and the Prognostic Roles of PTPN Family Members in Digestive Tract Cancers
Preprint: Please note that this article has not completed peer review. The expression patterns and the prognostic roles of PTPN family members in digestive tract cancers CURRENT STATUS: UNDER REVIEW Jing Chen The First Affiliated Hospital of China Medical University Xu Zhao Liaoning Vocational College of Medicine Yuan Yuan The First Affiliated Hospital of China Medical University Jing-jing Jing The First Affiliated Hospital of China Medical University [email protected] Author ORCiD: https://orcid.org/0000-0002-9807-8089 DOI: 10.21203/rs.3.rs-19689/v1 SUBJECT AREAS Cancer Biology KEYWORDS PTPN family members, digestive tract cancers, expression, prognosis, clinical features 1 Abstract Background Non-receptor protein tyrosine phosphatases (PTPNs) are a set of enzymes involved in the tyrosyl phosphorylation. The present study intended to clarify the associations between the expression patterns of PTPN family members and the prognosis of digestive tract cancers. Method Expression profiling of PTPN family genes in digestive tract cancers were analyzed through ONCOMINE and UALCAN. Gene ontology enrichment analysis was conducted using the DAVID database. The gene–gene interaction network was performed by GeneMANIA and the protein–protein interaction (PPI) network was built using STRING portal couple with Cytoscape. Data from The Cancer Genome Atlas (TCGA) were downloaded for validation and to explore the relationship of the PTPN expression with clinicopathological parameters and survival of digestive tract cancers. Results Most PTPN family members were associated with digestive tract cancers according to Oncomine, Ualcan and TCGA data. For esophageal carcinoma (ESCA), expression of PTPN1, PTPN4 and PTPN12 were upregulated; expression of PTPN20 was associated with poor prognosis.
