Natural products are rich sources of gene modulators that may be useful in prevention and treatment of cancer. Recently, nonsteroidal anti-inflammatory drug (NSAID) activated gene-1 (NAG-1) has been focused as a target of action against diverse cancers like colorectal, pancreatic, prostate, and breast. A variety of natural agents have been reported to play a pivotal role in regulation of NAG-1 through multiple transcriptional mechanisms. The aim of this paper is to review the NAG-1 modulators derived from natural products including plants, marine organisms, and microorganisms. Plant extracts belonging to the families of Fabaceae (Astragalus membranaceus), Ranunculaceae (Coptis chinensis), Menispermaceae (Coscinium fenestratum), Umbelliferae (Pleurospermum kamtschaticum), Lamiaceae (Marubium vulgare), and Rosaceae (Prunus serotina) increased the protein expression of NAG-1 in human colon cancer or hepatocarcinoma cells. Phytochemicals in the class of flavonoids (apigenin, quercetin, isoliquiritigenin, and 2′-hydroxyflavanone), isoflavonoids (formononetin and genistein), catechins (epigallocatechin gallate and epicatechin gallate), stilbenoids (resveratrol and pinosylvin), phenolics (6-gingerol), phloroglucinols (rottlerin and aspidin PB), terpenoids (18α-glycyrrhetinic acid, platycodin D, pseudolaric acid B, and xanthorrhizol), alkaloids (berberine, capsaicin, and indole-3-carbinol), lignans (isochaihulactone), anthraquinones (damnacanthal), and allyl sulfides (diallyl disulfide) elicited NAG-1 overexpression in various cancer cells. Pectenotoxin-2 from marine organisms and prodigiosin and anisomycin from microorganisms were also reported as NAG-1 modulators. Several transcription factors including EGR-1, p53, ATF-3, Sp1 and PPARγ were involved in natural products-induced NAG-1 transcriptional signaling pathway. [Display omitted]
