摘要: Despite long and intensive investigation, the mechanisms by
which nitric oxide (NO) regulates immune function and carcinogenesis remain
incompletely understood. Protein S-nitrosylation, the covalent attachment
of a nitroso group to a cysteine thiol, has emerged as a central mechanism
of NO-dependent cellular regulation. In particular, recent research has
revealed important roles for S-nitrosylation/denitrosylation in modulating
the activity of macrophage and tumor cell proteins, implicating Snitrosylation
in the regulation of macrophage function as well as in tumor
development and response to therapy. This review summarizes recent progress
in the identification and characterization of S-nitrosylated proteins in
macrophages and cancer cells. The review highlights key findings and insights obtained
from functional and proteomic studies about the roles of S-nitrosylation in signaling, transcription,
apoptosis and other cellular processes relevant to macrophage function and cancer
progression. Some of the implications of recent discoveries for the development of novel
anticancer approaches are also discussed.
