Sodium butyrate (NaBt), as one of the HDACi, has been demonstrated that it induces apoptosis, cell cycle arrest, the inhibition of angiogenesis, metastasis and gene expression changes. To date, there are several studies perfomed to investigate its therapeutic effect; however, theexact mechanism at molecular level is not clear yet. Therefore, the current thesis was aimed to clarify the action/theurapeutic potential mechanisms of sodium butyrate in Caco2 colon cancer cell line at molecular level using ATR-FTIR spectroscopy, quantitative spectral and chemometric analyses. 3mM, 6mM and 9mM doses of sodium butyrate were applied to Caco2 cell line line for 12h, 24h and 48 h. According to the results, NaBt treatment caused an increase in the unsaturated lipids, impying elevated lipid peroxiation. Moreover increased saturated lipids, membrane fluidity/dynamics and esters and triacylglycerols were obtained in NaBt-treated groups with respect to the control ones. However, NaBt induced a degradation of proteins and nucleic acids. HCA and PCA results indicated that in all studied doses, there was a clear distinction between studied groups in a time dependent manner. The results of the current study implied that sodium butyrate may have therapeutic potential by structural and functional remodelling of cancer cells.

Investigation of the molecular pathways involved in intestinal epithelial differentiation
Sade Memişoğlu, Aslı; Banerjee, Sreeparna; Department of Biology (2014)
The molecular mechanisms of balanced and continuous generation of intestinal epithelial cells, is poorly understood and disruption of this balance may result in neoplastic transformation and malignant growth. Differentiation is regulated by numerous signals, which in turn regulate signaling pathways directing activation or inactivation of certain transcription factors. Perturbations like changes in Ca2+ levels, glucose or amino acid starvation result in an ER stress response, which is also implicated in the...
The Effect of 15-lipoxygenase-1 (15-LOX-1) on angiogenesis in colorectal and prostate cancer
Çolakoğlu, Melis; Banerjee, Sreeparna; Department of Biology (2017)
15-lipoxygenase-1 (15-LOX-1) is one of the lipoxygenases (LOX) that are important for the generation of inflammatory bioactive lipids, which then result in the initiation and resolution of inflammation. The enzyme mainly metabolizes the omega-6 fatty acid, linoleic acid, to 13-(S)-HODE. In colorectal carcinoma, the tumor suppressive role of 15-LOX-1 is highlighted with decreased proliferation, induction of apoptosis, reduced motility and invasion. Oppositely, the expression of 15-LOX-1 was reported to have ...
Building Dicer1 regulation network of mouse liver hepatocytes
Ünsal, Şeyma; Beyge, Mahmut; Aydın Son, Yeşim (2012-06-29)
RNA induced gene silencing complex (RISC) has a role in many cellular processes which includes regulation of gene expression, immune response, cell differentiation and embryonic development. Dicer protein is a key regulator of these processes. Dicer1 specifically has central role in maturation of RISC substrate RNA and RISC assembly in mouse. Here the results of a microarray study that investigates the molecular level changes in dicer1 knockout mouse liver hepatocytes is re-analysed and the differentially r...
Evaluation of methylation profiles of an epidermal growth factor receptor gene in a head and neck squamous cell carcinoma patient group
Mutlu, M.; Mutlu, Pelin; Azarkan, S.; Baylr, Ö.; Öcal, B.; Saylam, G.; KORKMAZ, MEHMET HAKAN (2021-03-23)
Upregulation of the epidermal growth factor receptor (EGFR) gene has shown an important impact on the development of head and neck cancers due to its important regulation role on multiple cell signaling pathways. The aim of this study was to investigate the methylation pattern of the promoter region of the EGFR gene between head and neck squamous cell carcinoma (HNSCC) patients and a control group. Forty-seven unrelated HNSCC patients, clinically diagnosed at the Department of Otorhinolaryngology, Dlşkapl Y...
Molecular cloning, characterization, and homologous expression of an endochitinase gene from Bacillus thuringiensis serovar morrisoni
Okay, Sezer; Özcengiz, Gülay (2011-01-01)
The endochitinase gene (chi3023) of Bacillus thuringiensis (Bt) serovar morrisoni strain 3023 was amplified via polymerase chain reaction (PCR) and cloned in Escherichia coli. The ORF of chi3023 (GenBank Accession Number: DQ993175) consists of 2031 nucleotides encoding a 676-residue protein with a calculated molecular mass of 74.5 kDa and a pI value of 6.0. The amino acid sequence of Chi3023 was compared with previously sequenced Bt chitinases and the phylogenetic relationships among them were determined. T...
