Results Chromatin remodeling factor LSH is overexpressed in NPC To determine the role of LSH in NPC, we performed immunohistochemical analysis in tissues derived from NPC patients. LSH protein was present.1A). is a key mechanism of cancer progression including metastasis (13C17). The metabolic reprogramming that is associated with EMT demands fundamental changes of regulatory networks (16). EMT is a dynamic and reversible process and is provoked by signals from the microenvironments (17, 18). Whether and how metabolic intermediates are involved in EMT during cancer progression remains poorly understood. Altered cellular metabolism, in particular the Warburg effect, is a hallmark of cancer cells, with the tricarboxylicacid (TCA) cycle at the center of oxidative metabolism serving as a robust source for intermediates required for anabolic reactions (19, 20). Oncometabolites are defined as metabolites whose abnormal expression causes metabolic and epigenetic dysregulation and transformation to malignancy (21). The mitochondrial enzyme fumarate hydratase (FH), a key component of the TCA cycle, catalyzes the hydration of fumarate to malate and is essential for cellular energy production and macromolecular biosynthesis. FH has been identified as a tumor suppressor, and its inactivation by genetic mutations alters the level of 2-oxoglutarateCdependent oxygenases and leads to epigenetic deregulation of oncogenes or tumor suppressors (21, 22). The molecular mechanisms by which FH gene expression is controlled remain unclear. EpsteinCBarr virus (EBV) infects more than 90% of the global adult population and contributes to UF010 several malignancies including nasopharyngeal carcinoma (NPC), a prevalent cancer in the southern region of China and South-East Asia (23, 24). Epigenetic changes induced by EBV are key events in the viral process of carcinogenesis. Chromatin remodeling factors are crucial factors of epigenetics and play a critical part in the development of several malignancies (25, 26), but their role in the progress of NPC remains unknown.
