Lung cancer in never smokers (LCINS) is a common cause of cancer mortality but its genomic landscape is poorly characterized. Here high-coverage whole-genome sequencing of 232 LCINS showed 3 subtypes defined by copy number aberrations. The dominant subtype (piano), which is rare in lung cancer in smokers, features somatic UBA1 mutations, germline AR variants and stem cell-like properties, including low mutational burden, high intratumor heterogeneity, long telomeres, frequent KRAS mutations and slow growth, as suggested by the occurrence of cancer drivers' progenitor cells many years before tumor diagnosis. The other subtypes are characterized by specific amplifications and EGFR mutations (mezzo-forte) and whole-genome doubling (forte). No strong tobacco smoking signatures were detected, even in cases with exposure to secondhand tobacco smoke. Genes within the receptor tyrosine kinase-Ras pathway had distinct impacts on survival; five genomic alterations independently doubled mortality. These findings create avenues for personalized treatment in LCINS.

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 ...
Structural mapping and network analysis of patient-specific mutations in glioblastoma
Kaya, Tuğba; Tunçbağ, Nurcan; Doğan, Tunca; Department of Bioinformatics (2018)
Cancer is one of the most common cause of death worldwide. It occurs as a result of a collection of somatic deviations from normal state. Therefore, many efforts have been invested to profile mutations in different types of tumors; such as, the Cancer Genome Atlas (TCGA) which deposits multiple omic data for more than 11,000 tumor samples. In this thesis, we present a pipeline which retrieves patient-specific mutation data in Glioblastoma from TCGA, maps these mutations on the protein structures in Protein ...
Risk analysis based on spatial analysis of chronic obstructive pulmonary disease (COPD) and lung cancer with respect to provinces in Turkey
Çiftçi, Sezgin; Başbuğ Erkan, Berna Burçak; Düzgün, H. Şebnem; Department of Actuarial Sciences (2012)
The goal of this thesis is to analyze and understand the risks of Chronic Obstructive Pulmonary Disease (COPD) and lung cancer with respect to the provinces of Turkey according to the results of spatial analysis. The insurance sector of the country needs that kind of analysis to make more precise pricing in insurance products. Especially in health and life insurance products, morbidities like COPD and lung cancer may a ect the life expectancy as much as the premiums. COPD and lung cancer prevalence may exhi...
Development and Characterization of PEG-B-PCL Micelles Carrying Anticancer Agents
Işık, Gülhan; Tezcaner, Ayşen; Hasırcı, Nesrin; Department of Biotechnology (2022-2-9)
Cancer is a disease that decreases the quality of life. Many cancer drugs are either toxic or not effective due to their fast removal by reticuloendothelial system. Therefore, nano-sized drug delivery systems, especially the ones carrying the drugs directly to tumor, gained attention in the last decades. The aim of the study was to prepare nano-sized drug carrying micelles (drug conjugated and drug loaded) from methoxy polyethylene glycol-block-polycaprolactone (mPEG-b-PCL). In order to conjugate drugs, mPE...
Reversal of multidrug resistance by synthetic and natural compounds in drug-resistant MCF-7 cell lines
Kars, Meltem Demirel; Iseri, Ozlem Darcansoy; Gündüz, Ufuk; Molnar, Jozsef (2008-01-01)
Background: Ineffectiveness of anticancer drugs is frequently observed in cancer chemotherapy. The resistance of tumor cells to various cytotoxic drugs is defined as multidrug resistance (MDR). The purpose of this study is to investigate the potential reversal effect of some synthetic and natural chemicals on drug-resistant MCF-7 cell lines. The effects of potential MDR modulators combined with some anticancer drugs were also studied. Methods: Flow cytometry, MTT cytotoxicity assays and checkerboard combina...
