Breast cancer is the most frequent malignancy in women worldwide and is curable in ~70–80% of patients with early- stage, non- metastatic disease. In Breast cancer there are pathways related to Luminal A breast cancer, Luminal B breast cancer, HER2 positive breast cancer, Basal like/Triple negative breast cancer. The crucial signal transduction pathways in a breast cancerous cell includes pathways like PKB (protein kinase B), MAPK (mitogen-activated protein kinase), MTOR (mammalian target of rapamycin), Fas ligand (Type-II transmembrane protein), Notch (single-pass transmembrane receptor), SHH (Sonic Hedgehog), Tnf (tumor necrosis factor), Wnt (wingless/integrated) pathways. The Systems Biology Markup Language (SBML) is a file format for representing computational models, helping to interpret data and understand biological functions, in a declarative form that different software systems can exchange. SBML is oriented towards describing biological processes, including metabolic pathways, cell signaling pathways, and many others. Therefore, differentially expressed pathways can be simulated by using SBML which contain metabolites in specific pathway. In order to calculate fold change expression levels of genes in breast cancer, GSE15852 (Expression data from human breast tumors and their paired normal tissues) containing 43 healthy tissue samples and 43 tumor tissue samples is used and analyzed in R via DeSeq2 packages. Gene Set Enrichment Analysis are carried out in R with clusterProfiler package. The pathway analysis is performed in KEGG pathways. According to the expression values of proteins and their forward and reverse reaction constant, pathway simulations in healthy tissues and tumor tissues are performed by PySB to indicate their changes in breast cancer. With ARIMA method significant chances in metabolite’s amounts in a certain time interval are compared between healthy and tumor tissues.

Preparation and characterization of poly(d,l-lactide-co-glycolide) microspheres for controlled release of anticancer drugs
Eyövge, Gökçen; Gündüz, Ufuk; Department of Biotechnology (2005)
Breast cancer is the most frequent type of cancer seen in woman. Chemotherapy is one of the most important treatments for breast cancer. However, systemic toxicity, drug resistance and unstable kinetics of the drug in the blood are serious problems of chemotherapy. The use of biodegradable polymers for controlled release of anticancer drugs has gained popularity in recent years. Controlled release of anticancer drugs from polymeric carriers has some advantages such as improvement in the efficiency of treatm...
Investigation of the effects of combine use of cisplatin and metformin on proliferation of prostate cancer cell lines and gstp, cyp17a1 and hexokinase II enzymes
Durukan, Özlem; Adalı, Orhan; Arslan, Şevki; Department of Biochemistry (2016)
Prostate cancer is the most common cancer type both in developed and developing countries. Since 2015, it has been seen as one of the main cause of death in males, both in the world and in our country. Current therapeutic approaches for prostate cancer generally have variable efficiency, develop metastasis and drug resistance, and have high toxicity to normal tissues. Hence, the searching for more effective strategies with moderate or any adverse effects for the chemopreventive intervention of those cancers...
Identification of polymorphisms on the MDR1 gene among Turkish population and their effects on multidrug resistance in acute leukemia patients
Kaya, P; Gündüz, Ufuk; Arpaci, F; Ural, AU; Guran, S (2005-09-01)
Multidrug-resistance (MDR) phenotype is a serious limitation to the effective chemotherapeutic treatment of many cancer types, including leukemia. One of the most important proteins, the over-expression of which is responsible for the multidrug-resistance phenotype in many cancer types, is P-glycoprotein. This protein is the product of the MDR1 gene. In previous studies, single-nucleotide polymorphisms (SNPs) C3435T, G2677T, and T-129C in the MDR1 gene were shown to be correlated with lower P-glycoprotein e...
Identification of Potential Therapeutic Genes and Pathways in Phytoestrogen Emodin Treated Breast Cancer Cell Lines via Network Biology Approaches
Sakalli-Tecim, Elif; Uyar-Arpaci, Pembegul; Güray, Nülüfer Tülün (2021-02-01)
Phytoestrogens have been investigated for their potential anti-tumorigenic effects in various cancers including breast cancer. Emodin being a phytoestrogen shows anti-carcinogenic properties especially in estrogen receptor positive (ER+) breast cancers. The aim of this study is to identify the molecular mechanism and related biological pathways in both (ER+) MCF-7 and (ER-) MDA-MB-231 breast cancer cell lines upon Emodin treatment via microarray analysis in order to find out therapeutic biomarkers. In both ...
Comparison of the Diagnostic Accuracy of Next Generation Sequencing and Microarray Resequencing Methods for Detection of BRCA1 and BRCA2 Gene Mutations
Bahsi, Taha; Ergun, Sezen Güntekin; Ergun, Mehmet Ali; Perçin, E. Ferda (Gazi University, 2018-4-1)
Objective: Breast cancer constitutes 29 % of estimated new cases of cancer in women, and it is also one of the major cause of death in all cancer types. In this study, DNA samples of familial breast cancer patients with BRCA1 and BRCA2 mutations which had been analyzed using conventional DNA sequencing method, were also analyzed with new methods including microarray and next generation sequencing (NGS) in order to compare their results Methods: Seven patients with BRCA1 mutation, one patient with BRCA2 m...
