Hepatocellular Carcinoma is one of the major causes for mortality in the world and is usually asymptomatic until late stage decreasing the survival rate. There is an increase of incidence every year and current diagnostic and prognostic bio markers like AFP have their limitations in the wider context. Therefore, it is important to develop novel biomarkers. The aim of the Research is to understand the cytosine methylation and investigate the role of the p16 and SLIT-2 genes as biomarkers in Hepatocellular Carcinoma. The methylation profiles of the genes were assessed on bisulfite modified DNA samples with the aid of Real …

In the past decade, bioanalytical method development has become an integral part of clinical diagnosis, biomarker discovery, and drug discovery and development. The new and emerged bioanalytical technologies allow the quantitative and qualitative analysis of small molecules and biomolecules with high sensitivity and specificity. Specifically, the bioanalytical methods based on LC-MS and methylation-specific PCR are well suited for detecting low-abundance metabolites, proteins, and DNA in biofluids and tissues for biomarker investigation. They offer great clinical promises for early diseases diagnosis and therapeutic interventions. Besides, the LC-MS/MS quantitative method is essential for the estimation of pharmacokinetic and toxicological properties in drug …

Cancer is a result of unregulated cell growth. For all types of cancer currently studied, the transition from a healthy cell to a malignant tumor cell is a step-by-step process which requires mutation in at least several oncogenes and tumor suppressor genes together. Another cancer early event is DNA methylation. Cancer-related DNA methylation focuses on promoter hypermethylation of the certain genes. The DNA mutation and methylation profile can serve as biomarkers for diagnosing early stage of cancer. Colorectal cancer is the third most common cancer type in the United States and has been well studied. The essential mechanism of cancer …

DNA methylation is a key event regulating gene expression. DNA methylation analysis plays a pivotal role in unlocking association of epigenetic events with cancer. However, simultaneous evaluation of the methylation status of multiple genes is still a technical challenge. Microarray is a promising approach for high-throughput analysis of the methylation status at numerous CpG sites within multiple genes of interest. In this dissertation study, we conducted a systematic study to examine the use of microarray methods for methylation analysis. First, a robust universal microarray was established with more flexible in design and content, and potential cost saving over commercial arrays. …
