For instance, high-grade serous carcinomas arise from the ovary or fallopian tube and display a high frequency of p53 and BRCA1/2 mutations [6], whereas clear cell and endometrioid tumours have been linked to endometriosis and harbour PI3K mutations [7]. Moreover, mucinous ovarian carcinomas, which buy LEE011 comprise the least common subtype, are considered to be secondary metastases to the ovary from other tumours, particularly those found in the gastrointestinal tract [8]. Due

to the widespread heterogeneity among ovarian cancers, standard conventional therapies often elicit varying treatment responses within the various subclasses of tumours. For example, clear cell carcinomas often exhibit lower response

rates in comparison to high-grade serous tumours following administration of platinum-based drugs [9]. For these reasons, the ability to make definitive subtype diagnoses in order to treat patients accordingly would be extremely useful. The notion of treating patients on such an individual basis, also known as personalized medicine, has thus become a much desired model of care for OvCa patients. Personalized medicine is defined as PF 01367338 the utilization of an individual’s biological profile to guide decisions in the prevention and clinical management of diseases. Within OvCa, it has become increasingly apparent that each subtype represents a distinct genetic and etiological disease that simply shares a common anatomical location. Thus, it is imperative to delineate the differences between each subtype as well as understand the molecular processes by which tumours acquire resistance in order to construct therapeutic interventions that could be tailored on an individual basis. Such approaches to personalized medicine has been the focus of the majority of OvCa Enzalutamide studies as comprehensive characterization of the subtypes would greatly aid in the development

of subtype-specific management, which in turn would greatly improve patient outcome. With the recent advent of high-throughput technologies, numerous studies have been undertaken to profile the subtypes of OvCa using genomic, transcriptomic and proteomic approaches in order to identify subpopulations that could potentially benefit from personalized medicine. Specifically, proteomic profiling of OvCa has mainly revolved around the analysis of OvCa cell lines, tissues, and proximal fluids using mass spectrometry (MS). This has led to the identification of numerous altered protein expression patterns of the disease. The study of protein expression in OvCa has been increasingly important as proteins are the mediators of all biological processes and the molecular targets of the majority of drugs. Moreover, the proteome integrates the cellular genetic information and environmental influences.
