Although significant variations in the metabolic profiles exist among different cells, little is understood in terms of genetic regulations of such cell type-specific metabolic phenotypes and nutrient requirements. While many cancer cells depend on exogenous glutamine for survival to justify

The initial events of HIV-1 cell infection involve the sequential binding of the viral envelope glycoprotein gp120 to the cellular CD4 receptor and the coreceptor, usually CCR5 or CXCR4. Binding to the coreceptor triggers the chain of events that culminates
