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, ...

Evaluation of X chromosome inactivation with respect to HLA genetic susceptibility in rheumatoid arthritis and systemic sclerosis

Kanaan, S. B.; Onat, O. E.; Balandraud, N.; Martin, G. V.; Nelson, J. L.; Azzouz, D. F.; Auger, I.; Arnoux, F.; Martin, M.; Roudier, J.; Ozcelik, T.; Lambert, N. C. (Public Library of Science, 2016)

Background: Autoimmune diseases, including rheumatoid arthritis (RA) and systemic sclerosis (SSc) are characterized by a strong genetic susceptibility from the Human Leucocyte Antigen (HLA) locus. Additionally, disorders ...

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 ...

Extremely skewed X-chromosome inactivation patterns in women with recurrent spontaneous abortion

Bagislar, S.; Ustuner, I.; Cengiz, B.; Soylemez, F.; Akyerli, C. B.; Ceylaner, S.; Ceylaner, G.; Acar, A.; Ozcelik, T. (Wiley-Blackwell Publishing Asia, 2006)

Background: The role of extremely skewed X-chromosome inactivation (XCI) has been questioned in the pathogenesis of recurrent spontaneous abortion (RSA) but the results obtained were conflicting. Aims: We therefore ...

Increased frequency of extremely skewed X chromosome inactivation in juvenile idiopathic arthritis

Uz, E.; Mustafa, C.; Topaloglu, R.; Bilginer, Y.; Dursun, A.; Kasapcopur, O.; Ozen, S.; Bakkaloglu, A.; Ozcelik, T. (John Wiley & Sons, Inc., 2009)

Objective. Juvenile idiopathic arthritis (JIA) is a childhood rheumatic disease of unknown etiology. Two subgroups of JIA, i.e., oligoarticular and polyarticular, are thought to have an autoimmune component, and show a ...

Skewed X inactivation in an X linked nystagmus family resulted from a novel, p.R229G, missense mutation in the FRMD7 gene

Kaplan, Y.; Vargel, I.; Kansu, T.; Akin, B.; Rohmann, E.; Kamaci, S.; Uz, E.; Ozcelik, T.; Wollnik, B.; Akarsu, N. A. (BMJ Group, 2008)

Aims: This study aimed to identify the underlying genetic defect of a large Turkish X linked nystagmus (NYS) family. Methods: Both Xp11 and Xq26 loci were tested by linkage analysis. The 12 exons and intron-exon junctions ...

Skewed X-chromosome inactivation in scleroderma

Uz, E.; Loubiere, L. S.; Gadi, V. K.; Ozbalkan, Z.; Stewart, J.; Nelson, J. L.; Ozcelik, T. (Springer New York, 2008)

Scleroderma is a female-prevalent autoimmune disease of unclear etiology. Two fundamental gender differences, skewed X-chromosome inactivation (XCI) and pregnancy-related microchimerism, have been implicated in scleroderma. ...
