MicroRNA-519a is a novel oncomir conferring tamoxifen resistance by targeting a network of tumour-suppressor genes in ER+ breast cancer

Ward, A.; Shukla, K.; Balwierz, A.; Soons, Z.; König, R.; Sahin, O.; Wiemann, S. (John Wiley and Sons Ltd, 2014)

Tamoxifen is an endocrine therapy which is administered to up to 70% of all breast cancer patients with oestrogen receptor alpha (ERα) expression. Despite the initial response, most patients eventually acquire resistance ...

Early postzygotic mutations contribute to de novo variation in a healthy monozygotic twin pair

Dal, G. M.; Ergüner, B.; Saǧıroǧlu, M. S.; Yüksel, B.; Onat, O. E.; Alkan C.; Özçelik, T. (B M J Group, 2014)

Background: Human de novo single-nucleotide variation (SNV) rate is estimated to range between 0.82-1.70×10-8 mutations per base per generation. However, contribution of early postzygotic mutations to the overall human de ...

Patrolling monocytes control tumor metastasis to the lung

Hanna, R. N.; Cekic, C.; Sag, D.; Tacke, R.; Thomas, G. D.; Nowyhed, H.; Herrley, E.; Rasquinha, N.; McArdle, S.; Wu, R.; Peluso, E.; Metzger, D.; Ichinose, H.; Shaked, I.; Chodaczek, G.; Biswas, S. K.; Hedrick, C. C. (American Association for the Advancement of Science, 2015)

The immune system plays an important role in regulating tumor growth and metastasis. Classical monocytes promote tumorigenesis and cancer metastasis, but how nonclassical "patrolling" monocytes (PMo) interact with tumors ...

Characterization of a novel zebrafish (Danio rerio) gene, wdr81, associated with cerebellar ataxia, mental retardation and dysequilibrium syndrome (CAMRQ)

Doldur-Balli, F.; Ozel, M. N.; Gulsuner, S.; Tekinay, A. B.; Ozcelik, T.; Konu, O.; Adams, M. M. (BioMed Central Ltd., 2015)

Background: WDR81 (WD repeat-containing protein 81) is associated with cerebellar ataxia, mental retardation and disequilibrium syndrome (CAMRQ2, [MIM 610185]). Human and mouse studies suggest that it might be a gene of ...

Interplay between 15-lipoxygenase-1 and metastasisassociated antigen 1 in the metastatic potential of colorectal cancer

Tunçer, S.; Çağatay, T. S.; Keşküş, A. G.; Çolakoğlu, M.; Konu, Ö.; Banerjee S. (Wiley-Blackwell Publishing Ltd., 2016)

Objectives: Metastasis-associated antigen 1 (MTA1) is implicated in metastasis while 15-lipoxygenase-1 (15-LOX-1) reduces cell motility, when re-expressed in colorectal cancer (CRC). We aimed to understand any potential ...

Functionally conserved effects of rapamycin exposure on zebrafish

Sucularli, C.; Shehwana, H.; Kuscu, C.; Dungul, D. C.; Ozdag, H.; Konu, O. (Spandidos Publications, 2016-03)

Mechanistic target of rapamycin (mTOR) is a conserved serine/threonine kinase important in cell proliferation, growth and protein translation. Rapamycin, a well-known anti-cancer agent and immunosuppressant drug, inhibits ...

The miR-644a/CTBP1/p53 axis suppresses drug resistance by simultaneous inhibition of cell survival and epithelialmesenchymal transition in breast cancer

Raza, U.; Saatci, O.; Uhlmann, S.; Ansari, S. A.; Eyüpoglu, E.; Yurdusev, E.; Mutlu, M.; Ersan, P. G.; Altundağ, M. K.; Zhang, J. D.; Dogan, H. T.; Güler, G.; Şahin, Ö. (Impact Journals LLC, 2016)

Tumor cells develop drug resistance which leads to recurrence and distant metastasis. MicroRNAs are key regulators of tumor pathogenesis; however, little is known whether they can sensitize cells and block metastasis ...

Identification of differentially expressed microRNAs during lipotoxic endoplasmic reticulum stress in RAW264.7 macrophages

Nadir, M.; Tufanlı, Ö.; Erbay, E.; Atalay, A. (Turkish Biochemistry Society, 2016-06)

Objective: Increased fatty acids in the circulation and their accumulation in non-adipose tissues play a significant role in the development of obesity related metabolic and inflammatory disorders such as insulin resistance, ...

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 ...

Metastasis suppressor proteins in cutaneous squamous cell carcinoma

Bozdogan, O.; Vargel, I.; Cavusoglu, T.; Karabulut, A. A.; Karahan, G.; Sayar, N.; Atasoy, P.; Yulug, I. G. (Elsevier, 2016-07)

Cutaneous squamous cell carcinomas (cSCCs) are common human carcinomas. Despite having metastasizing capacities, they usually show less aggressive progression compared to squamous cell carcinoma (SCC) of other organs. ...
