The ability to generate senescent progeny as a mechanism underlying breast cancer cell heterogeneity
Mumcuoğlu, Mine; Bağışlar, Sevgi; Yüzügüllü, Haluk; Alotaibi, Hani; Şentürk, Şerif; Telkoparan, Pelin; Gür-Dedeoğlu, Bala; Cingöz, Burcu; Bozkurt, B.; Tazebay, Uygar H.; Yuluğ, Işık G.; Akçalı, Kamil Can; Öztürk, Mehmet (Public Library of Science, 2010)Background Breast cancer is a remarkably heterogeneous disease. Luminal, basal-like, "normal-like", and ERBB2+ subgroups were identified and were shown to have different prognoses. The mechanisms underlying this heterogeneity ... -
Aflatoxin genotoxicity is associated with a defective DNA damage response bypassing p53 activation
Gürsoy-Yüzügüllü, Özge; Yüzügüllü, Haluk; Yılmaz, Mustafa; Öztürk, Mehmet (John Wiley & Sons, 2011)Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer deaths. Aflatoxins, which may play a causative role in 5-28% of HCCs worldwide, are activated in liver cells and induce principally G→T mutations, ... -
Biology of hepatocellular cancer
Öztürk, Mehmet; Çetin Atalay, Rengül (Lippincott-Raven, 2003) -
Comparative evaluation of in vitro cytotoxic effects among parent abietyl alcohol and novel fatty acid ester derivatives against MCF7 and hepatocellular carcinoma cell lines
Mustufa, Muhammad Ayaz; Aslam, A.; Özen, Çiğdem; Hashmi, I. A.; Naqvi, N.; Öztürk, Mehmet; Ali, F. I. (Pakistan Journal of Pharmaceutical Sciences, 2014)Synthesis of twelve hitherto unreported esters of abietyl alcohol and screening of these esters against four cancer cell lines including one breast cancer line MCF7 and four hepatocellular carcinoma cell lines (HCC) Huh7, ... -
Development of a novel zebrafish xenograft model in ache mutants using liver cancer cell lines
Avcı, M. Ender; Keskus, Ayşe Gökçe; Targen, Seniye; Işılak, M. Efe; Öztürk, Mehmet; Çetin-Atalay, Rengül; Adams, Michelle M.; Konu, Özlen (Nature Publishing Group, 2018)Acetylcholinesterase (AChE), an enzyme responsible for degradation of acetylcholine, has been identified as a prognostic marker in liver cancer. Although in vivo Ache tumorigenicity assays in mouse are present, no established ... -
Differential expression of epigenetic regulatory genes in liver cancer
Yıldız, Gökhan; Öztürk, Mehmet (International Liver Cancer Association, 2012-09)Epigenetic mechanisms are involved in the organization of chromatin structure and global regulation of gene expression [1]. Cancer cells display multiple epigenetic changes including aberrations in the methylation of DNA, ... -
Genetics and epigenetics of liver cancer
Özen, Çiğdem; Yıldız, Gökhan; Dağcan, Alper Tunga; Çevik, Dilek; Örs, Ayşegül; Keleş, Umut; Topel, Hande; Öztürk, Mehmet (Elsevier, 2013)Hepatocellular carcinoma (HCC) represents a major form of primary liver cancer in adults. Chronic infections with hepatitis B (HBV) and C (HCV) viruses and alcohol abuse are the major factors leading to HCC. This deadly ... -
Molecular Biology of liver cancer
Öztürk, Mehmet; Çetin-Atalay, Rengül (Wiley-Blackwell Publishing, 2005)Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality worldwide. Recent advances in the molecular profiling of HCC emphasize its intratumoral heterogeneity and reveal how cellular pathways ... -
Novel anti-HER2 monoclonal antibodies: synergy and antagonism with tumor necrosis factor-α
Ceran, Ceyhan; Çokol, M.; Cingöz, S.; Taşan, İpek; Öztürk, Mehmet; Yağcı, Tamer (BioMed Central, 2012)Background: One-third of breast cancers display amplifications of the ERBB2 gene encoding the HER2 kinase receptor. Trastuzumab, a humanized antibody directed against an epitope on subdomain IV of the extracellular domain ... -
PATIKA: an integrated visual environment for collaborative construction and analysis of cellular pathways
Demir, Emek; Babur, Özgün; Doğrusöz, Uğur; Gürsoy, Atilla; Nişancı, Gürkan; Çetin Atalay, Rengül; Öztürk, Mehmet (Oxford University Press, 2002-06)Motivation: Availability of the sequences of entire genomes shifts the scientific curiosity towards the identification of function of the genomes in large scale as in genome studies. In the near future, data produced about ... -

Synthesis and characterization of amino acid conjugates of oleanolic acid and their in vitro cytotoxic effect on HCC cell lines
Mustufa, Muhammad Ayaz; Hashmi, I. A.; Manzoor, S.; Ahmed, A.; Ahmed, V.; Aslam, A.; Özen, Çiğdem; Naqvi, N.; Öztürk, Mehmet; Ali, F. I. (Pakistan Journal of Pharmaceutical Sciences, 2014)Oleanolic acid (3β-hydroxy-olean-12-en-28-oic acid; OA-01), a pentacyclic triterpene, exhibit a wide range of pharmacological and biological activities. We have isolated oleanolic acid from methanolic extract of Periploca ... -
Systematic analysis of cytostatic TGF-Beta response in mesenchymal-like hepatocellular carcinoma cell lines
Güngör, M. Z.; Uysal, M.; Öztürk, Mehmet; Şentürk, Şerif (Springer, 2021-08-31)Background Hepatocellular carcinoma (HCC) is one of the most challenging malignancies, with high morbidity and mortality rates. The transforming growth factor-β (TGF-β) pathway plays a dual role in HCC, acting as both ... -
Transforming growth factor-beta induces senescence in hepatocellular carcinoma cells and inhibits tumor growth
Şentürk, Şerif; Mumcuoğlu, Mine; Gürsoy-Yüzügüllü, Özge; Cingöz, Burcu; Akçalı, Kamil Can; Öztürk, Mehmet (American Association for the Study of Liver Disease, 2010)Senescence induction could be used as an effective treatment for hepatocellular carcinoma (HCC). However, major senescence inducers (p53 and p16Ink4a) are frequently inactivated in these cancers.We tested whether transforming ...
