cellular biosynthetic process definition: The chemical reactions and pathways resulting in the formation of substances, carried out by individual cells. [GOC:jl]
negative regulation of cellular biosynthetic process definition: Any process that stops, prevents or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of substances, carried out by individual cells. [GOC:mah]
positive regulation of cellular biosynthetic process definition: Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of substances, carried out by individual cells. [GOC:mah]
regulation of cellular biosynthetic process definition: Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of substances, carried out by individual cells. [GOC:mah]
cellular polysaccharide biosynthetic process definition: The chemical reactions and pathways resulting in the formation of polysaccharides, polymers of more than 10 monosaccharide residues joined by glycosidic linkages, occurring at the level of an individual cell. [GOC:go_curators]
cellular biopolymer biosynthetic process definition: The chemical reactions and pathways resulting in the formation of biopolymers, long, repeating chains of monomers found in nature, such as polysaccharides and proteins, as carried out by individual cells. [GOC:mah]

Both exposure to exogenous NO and cellular synthesis of NO in cell culture increased media levels of 8-epi-prostaglandin F2α, a marker of oxidative lipid damage, whereas inhibition of endogenous NO synthesis reduced media 8-epi-prostaglandin F2α formation to control levels.

Elevated intracellular levels of γ-tocopherol in response to the cellular inflammatory state may indicate that it serves a unique role in minimizing cellular damage resulting from endogenous NO synthesis.

The paradoxical increase in cellular tocopherol associated with the induction of NO synthesis may indicate either enhanced cellular transport/decreased export for tocopherols or recruitment of free tocopherol from tocopherol storage molecules.

The observed increase in cellular tocopherol concentrations may be an important component of the cell's response to infection and appears to be specifically associated with mitigating damage resulting from cellular NO synthesis.
