Colon cancer associated transcript-1 (CCAT1) expression in adenocarcinoma of the stomach

Mizrahi, I.; Mazeh, H.; Grinbaum, R.; Beglaibter, N.; Wilschanski, M.; Pavlov, V.; Adileh, M.; Stojadinovic, A.; Avital, I.; Gure, A. O.; Halle, D.; Nissan, A. (Ivyspring International Publisher, 2015)

Background: Long non-coding RNAs (lncRNAs) have been shown to have functional roles in cancer biology and are dys-regulated in many tumors. Colon Cancer Associated Transcript -1 (CCAT1) is a lncRNA, previously shown to be ...

The SOCS-1 gene methylation in chronic myeloid leukemia patients

Hatirnaz, O.; Ure, U.; Ar, C.; Akyerli, C.; Soysal, T.; Ferhanoǧlu, B.; Özçelik, T.; Ozbek, U. (John Wiley & Sons, Inc., 2007)

SOCS-1, an important protein in the JAK/STAT pathway, has a role in the down stream of BCR-ABL protein kinase. We investigated 56 CML patients and 16 controls for the methylation status of SOCS-1 gene promoter and Exon 2 ...

DNA repair gene polymorphisms and bladder cancer susceptibility in a Turkish population

Karahalil, B.; Kocabas, N. A.; Özçelik, T. (International Institute of Anticancer Research, 2006)

Background: Occupational exposure and life style preferences, such as smoking are the main known environmental susceptibility factors for bladder cancer. A growing list of chemicals has been shown to induce oxidative DNA ...

Mutations in RAD21 disrupt regulation of apob in patients with chronic intestinal pseudo-obstruction

Bonora, E.; Bianco, F.; Cordeddu, L.; Bamshad, M.; Francescatto, L.; Dowless, D.; Stanghellini, V.; Cogliandro, R. F.; Lindberg, G.; Mungan, Z.; Cefle, K.; Ozcelik, T.; Palanduz, S.; Ozturk, S.; Gedikbasi, A.; Gori, A.; Pippucci, T.; Graziano, C.; Volta, U.; Caio, G.; Barbara, G.; D'Amato, M.; Seri, M.; Katsanis, N.; Romeo, G.; De Giorgio, R. (W.B. Saunders, 2015)

Background Aims Chronic intestinal pseudo-obstruction (CIPO) is characterized by severe intestinal dysmotility that mimics a mechanical subocclusion with no evidence of gut obstruction. We searched for genetic variants ...

Analysis of skewed X-chromosome inactivation in females with rheumatoid arthritis and autoimmune thyroid diseases

Chabchoub, G.; Uz, E.; Maalej, A.; Mustafa, C. A.; Rebai, A.; Mnif, M.; Bahloul, Z.; Farid, N. R.; Ozcelik, T.; Ayadi, H. (BioMed Central, 2009)

Introduction The majority of autoimmune diseases such as rheumatoid arthritis (RA) and autoimmune thyroid diseases (AITDs) are characterized by a striking female predominance superimposed on a predisposing genetic background. ...

Evidence from autoimmune thyroiditis of skewed X-chromosome inactivation in female predisposition to autoimmunity

Ozcelik, T.; Uz, E.; Akyerli, C. B.; Bagislar, S.; Mustafa, C. A.; Gursoy, A.; Akarsu, N.; Toruner, G.; Kamel, N.; Gullu, S. (Nature Publishing Group, 2006)

The etiologic factors in the development of autoimmune thyroid diseases (AITDs) are not fully understood. We investigated the role of skewed X-chromosome inactivation (XCI) mosaicism in female predisposition to AITDs. One ...

Endothelial progenitor cells display clonal restriction in multiple myeloma

Braunstein, M.; Özçelik, T.; Baǧişlar, S.; Vakil, V.; Smith, E. L. P.; Dai, K.; Akyerli, C. B.; Batuman O. A. (BioMed Central Ltd., 2006)

Background: In multiple myeloma (MM), increased neoangiogenesis contributes to tumor growth and disease progression. Increased levels of endothelial progenitor cells (EPCs) contribute to neoangiogenesis in MM, and, ...

Skewed X chromosome inactivation in blood cells of women with scleroderma

Özbalkan, Z.; Baǧişlar, S.; Kiraz, S.; Akyerli, C. B.; Özer H. T. E.; Yavuz, Ş.; Birlik, A. M.; Çalgüneri, M.; Özçelik, T. (John Wiley & Sons, Inc., 2005)

Objective. Scleroderma (SSc) is an autoimmune disease of unknown etiology. The disease is 3-8 times more frequent in women than in men. The role of X chromosome inactivation (XCI) in the predisposition of women to autoimmunity ...

Expression of IFITM1 in chronic myeloid leukemia patients

We investigated the peripheral blood gene expression profile of interferon induced transmembrane protein 1 (IFITM1) in sixty chronic myeloid leukemia (CML) patients classified according to new prognostic score (NPS). IFITM1 ...

MDM2 T309G polymorphism is associated with bladder cancer

Onat, O. E.; Tez, M.; Özçelik, T.; Törüner, G. A. (International Institute of Anticancer Research, 2006)

Recently, a functional T to G polymorphism at nucleotide 309 in the promoter region of the MDM2 gene (rs: 2279744, SNP 309) has been identified. This polymorphism has an impact on the expression of the MDM2 gene, which is ...
