Bipolar disorder (BD), which is characterized by depression and mania, affects about 1% of the total world population. Current treatments are effective in only 40-60% of cases and cause severe side effects. Valproic acid (VPA), a branched short-chain fatty acid, is one of the most widely used drugs for the treatment of BD. Although many hypotheses have been postulated to explain the molecular mechanism of action of this drug in BD, the therapeutic mechanism is not understood. This knowledge gap has hampered the development of new drugs to treat this disorder. To identify candidate pathways affected by VPA, I performed ...


Regulation Of Inositol Biosynthesis And Cellular Consequences Of Inositol Depletion: Implications For The Mechanism Of Action Of Valproate, Rania M. Deranieh Jan 2014

Regulation Of Inositol Biosynthesis And Cellular Consequences Of Inositol Depletion: Implications For The Mechanism Of Action Of Valproate, Rania M. Deranieh

Inositol is a six-carbon cyclitol that is ubiquitous in biological systems. It is a precursor for the synthesis of numerous biologically important compounds, including inositol phosphates and phosphoinositides that are essential for cell function and viability. Inositol compounds play a role in membrane formation, gene regulation, signaling, regulation of ion channels, and membrane trafficking. Furthermore, inositol regulates hundreds of genes, including those involved in the biosynthesis of inositol and phospholipids. While transcriptional regulation of inositol biosynthesis has been extensively studied and well characterized, regulation of inositol biosynthesis at the enzymatic level has not been addressed. The current study shows that ...


Characterization And Identification Of Novel Regulators Of The Synthesis Of Phospholipids, Cunqi Ye Jan 2014

Characterization And Identification Of Novel Regulators Of The Synthesis Of Phospholipids, Cunqi Ye

Wayne State University Dissertations

Phospholipids are the most abundant lipids in cell membranes. The synthesis of phospholipids is crucial for cellular membrane biogenesis and nearly all aspects of cellular processes. Understanding the regulation of synthesis of phospholipids is beneficial to our fundamental knowledge of cell biology as well as human health.

Regulation of the synthesis of phospholipids is intensively studied in the yeast S. cerevisiae. Most notably, the synthesis of phospholipids is coordinated with the synthesis of inositol, a precursor of inositol-containing lipids, by controlling expression of the genes encoding phospholipid biosynthetic enzymes. In addition to this well-characterized regulatory circuit controlled by the trans-acting ...
