Hepatocellular carcinoma (HCC) is the most prevalent primary liver cancer and one of the leading causes of cancer associated death worldwide. This is due to the highly resistant nature of this malignancy and the lack of effective treatment options for advanced stage HCC patients. The hyperactivity of PI3K/Akt and Ras/Raf/MEK/ERK signaling pathways contribute to the cancer progression, survival, motility, and resistance mechanisms, and the interaction of these two pathways are responsible for the regulation of cancer cell growth and development. Therefore, it is vital to design and develop novel therapeutic options for HCC treatment targeting these hyperactive pathways. For this purpose, novel series of trans-indole-3-ylacrylamide derivatives originated from the lead compound, 3-(1H-indole-3-yl)-N-(3,4,5-trimethoxyphenyl)acrylamide, have been synthesized and analyzed for their bioactivity on cancer cells along with the lead compound. Based on the initial screening, the most potent compounds were selected to elucidate their effects on cellular signaling activity of HCC cell lines. Cell cycle analysis, immunofluorescence, and Western blot analysis revealed that lead compound and (E)-N-(4-tert-butylphenyl)-3-(1H-indole-3-yl)acrylamide induced cell cycle arrest at the G2/M phase, enhanced chromatin condensation and PARP-cleavage, addressing induction of apoptotic cell death. Additionally, these compounds decreased the activity of ERK signaling pathway, where phosphorylated ERK1/2 and c-Jun protein levels diminished significantly. Relevant to these findings, the lead compound was able to inhibit tubulin polymerization as well. To conclude, the novel trans-indole-3-ylacrylamide derivatives inhibit one of the critical pathways associated with HCC which results in cell cycle arrest and apoptosis in HCC cell lines.

Network-based discovery of molecular targeted agent treatments in hepatocellular carcinoma Fayetörbay, Rumeys; Tunçbağ, Nurcan; Department of Bioinformatics (2020) Hepatocellular carcinoma (HCC) is one of the most-deadly cancers and the most common type of primary liver cancer. Multikinase inhibitor Sorafenib is one of FDA approved targeted agents in HCC treatment. PI3K/AKT/mTOR pathway is altered in about 51% of HCC; hence, understanding how Sorafenib and PI3K/AKT/mTOR pathway inhibitors act at signaling level is crucial for targeted therapies and to reveal the off-target effects. In this work, we use gene expression profiles (GEPs) of HCC cells (Huh7 and Mahlavu) wh...
Karaciğer kanseri kök hücre ksenograft modelinde sitotoksik aktiviteli yeni ilaç adaylarının etkilerinin belirlenmesi Atalay, Rengül; Kahraman, Deniz Cansen(2017) Primer karaciğer kanseri (Hepatoselüler kanser, HSK) Dünya sağlık örgütü verilerine göre altıncı en sık görülen ve diğer kanser türleri arasında ölümcül olan ikinci kanser türüdür. Karaciğer kanserinin histolojik yapısı oldukça heterojendir. Sıklıkla siroz zemininde oluşan karaciğer kanseri, hepatik öncü hücre (Hepatic Progenitor Cells HPC) olarak adlandırılan hücrelerden kaynaklanmaktadır. Kök hücre belirteçlerini ve özelliklerini taşıyan bu hücreler, kronik hepatit ve siroz sürecinde uzun süreli hasara uğ...
Synthesis of novel indole-isoxazole hybrids and evaluation of their cytotoxic activities on hepatocellular carcinoma cell lines Hawash, Mohammed; Kahraman, Deniz Cansen; Ergun, Sezen Guntekin; Cetin-Atalay, Rengul; BAYTAŞ, SULTAN (2021-12-01) Background Liver cancer is predicted to be the sixth most diagnosed cancer globally and fourth leading cause of cancer deaths. In this study, a series of indole-3-isoxazole-5-carboxamide derivatives were designed, synthesized, and evaluated for their anticancer activities. The chemical structures of these of final compounds and intermediates were characterized by using IR, HRMS, H-1-NMR and C-13-NMR spectroscopy and element analysis. Results The cytotoxic activity was performed against Huh7, MCF7 and HCT116...
Characterization of liposomal celecoxib formulation as a drug delivery system in colorectal cancer cell lines Erdoğ, Aslı; Banerjee, Sreeparna; Department of Biotechnology (2012) Colorectal carcinoma (CRC) is one of the most common cancers and is the leading cause of cancer deaths in much of the developed world. Owing to the high incidence of drug resistance and potential toxic effects of chemotherapy drugs, much research is currently underway to design better strategies for smart drug delivery systems. Cyclooxygenase-2 (COX-2) pathway is associated with poor prognosis in colon carcinomas. The selective COX-2 inhibitor drug Celecoxib (CLX) has been shown to posses COX-2 independent ...
MECHANISMS OF SYNERGISTIC ANTITUMOR EFFECT OF NAPROXEN AND SORAFENIB IN HEPATOCELLULAR CARCINOMA Akar, Etkin; Muyan, Mesut; Kahraman, Deniz Cansen; Department of Biology (2023-1-23) Hepatocellular carcinoma (HCC) is life-threatening cancer that accounts for the second leading cause of cancer-related deaths worldwide. Due to the complexity and heterogeneity of HCC, which leads to resistance to current targeted therapies, combination therapy becomes an important strategy. Since 90% of HCC arises from chronic liver inflammation, HCC drugs combined with non-steroid anti- inflammatory drugs (NSAIDs) are considered an important strategy to increase treatment efficacy. In this study, we aimed...
