Colorectal carcinoma (CRC) is often lethal when invasion and/or metastasis occur. 15-Lipoxygenase-1 (15-LO-1), a member of the inflammatory eicosanoid pathway, oxidatively metabolizes linoleic acid and its expression is repressed in CRC. In this study, we investigated the hypothesis that the lack of 15-LO-1 expression in CRC cells might contribute to tumorigenesis. Therefore we introduced 15-LO-1 into HCT-116 and HT-29 cells that do not have detectable levels of 15-LO-1. Our data indicate that expression of 15-LO-1 significantly decreased cell proliferation and increased apoptosis. In addition, we observed a reduction in adhesion to fibronectin, anchorage-independent growth on soft agar, cellular motility and ability to heal a scratch wound, and migratory and invasive capacity across Matrigel. 15-LO-1 expression also reduced the expression of metastasis associated protein-1, a part of the nucleosome remodeling and histone deacetylase silencing complex. We propose that 15-LO-1 expression in CRC might contribute to the inhibition of metastatic capacity in vitro and can be exploited for therapeutic purposes. (Cancer Sci 2009;100: 2283-2291).

Identification of biomarkers associated with partial epithelial to mesenchymal transition in the secretome of slug over-expressing hepatocellular carcinoma cells
Karaosmanoglu, Oguzhan; Banerjee, Sreeparna; SİVAS, HÜLYA (Springer Science and Business Media LLC, 2018-08-01)
Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related deaths worldwide. Complete epithelial to mesenchymal transition (EMT) has long been considered as a crucial step for metastasis initiation. It has, however, become apparent that many carcinoma cells can metastasize without complete loss of epithelial traits or with incomplete gain of mesenchymal traits, i.e., partial EMT. Here, we aimed to determine the similarities and differences between complete and partial EMT through over-expr...
Functional characterization of 15-lipoxygenase-1 expression in human colorectal carcinoma cell line ht-29
Tunçay, Seda; Banerjee, Sreeparna; Department of Biology (2009)
Colorectal carcinoma (CRC) is often lethal when invasion and/or metastasis occur. 15-lipoxygenase-1 (15-LO-1), an enzyme of the inflammatory eicosanoid pathway, oxidatively metabolizes linoleic acid and its expression is repressed in CRC. In the present study, the hypothesis that the lack of 15-LO-1 expression in CRC cells may contribute to the tumorigenesis was investigated. Therefore 15-LO-1 was introduced to colon cancer cell line HT-29 that does not have detectable levels of the 15-LO-1. The HT-29 cells...
A new thiadiazine derivative induces oxidative stress dependent JNK pathway activation and cell death in hepatocellular carcinoma
Kahraman, Deniz Cansen; TOZKOPARAN KÖPRÜCÜ, BİRSEN; Atalay, Rengül (2019-07-01)
Hepatocellular carcinoma (HCC) is the fifth most common and the second lethal cancer worldwide. HCC is resistant to conventional chemotherapy and radiotherapy due to its highly heterogenous structure. Therefore, it is crucial to design and develop novel therapeutic strategies against HCC. Non-steroidal anti-inflammatory drugs (NSAIDs) have long been studied for the treatment of acute and chronic conditions with pain and inflammation. In recent years, evidence from various studies suggested that NSAIDs reduc...
Monoclonal antibodies for targeted therapy in colorectal cancer.
Banerjee, Sreeparna (Informa UK Limited, 2010-04-15)
Traditional therapeutic regimens of solid tumors such as chemotherapy and radiotherapy often do not distinguish between malignant and normal tissues, resulting in considerable side-effects. Monoclonal antibodies (mAbs), targeted against antigens dysregulated in cancers, have therefore generated great interest in both clinical and research settings. The antibodies are either chimeric or human(ized) and can bind to and inhibit target proteins overexpressed in both solid tumors and hematological malignancies. ...
Significance of genetic Polymorphisms at multiple loci of CYP2E1 in the risk of development of childhood acute lymphoblastic leukemia
Ulusoy, Gulen; Adalı, Orhan; Tumer, Tugba Boyunegmez; Sahin, Gurses; Gozdasoglu, Sevgi; Arinc, Emel (S. Karger AG, 2007-01-01)
Background/Aims: The molecular etiology of childhood acute lymphoblastic leukemia (ALL) is likely to involve interactions between environmental factors and genetic make up. Understanding these interactions between various predisposing genes for the risk of developing childhood leukemia is of considerable importance. CYP2E1 is a susceptible gene in this respect, especially for its capacity to bioactivate many procarcinogens including benzene and N-nitrosodimethylamine. The CYP2E1 gene possesses several polym...
