Cholesterol (cholesteryl alcohol) is a natural product that is the major sterol in mammals and an agonist of estrogen-related receptor α (ERRα). Cholesterol is widely found in the cell membranes of animals and is also used in the synthesis of several important hormones and bile acids.

N,N'-Dinitrosopiperazine (1,4-Dinitrosopiperazine; DNP) is a carcinogen that targets the nasopharyngeal epithelium to promote nasopharyngeal carcinoma (NPC) metastasis by modulating various signaling pathways through protein phosphorylation, notably phosphorylating LYRIC at serine 568 [1].

Zymosan A, a polysaccharide from Saccharomyces cerevisiae (brewer's yeast), is a TLR2 agonist that promotes regeneration of ISCs from intestinal stem cells after radiation injury by up-regulating ASCL2 through the TLR2 signaling pathway and the Wnt signaling pathway.Zymosan A stimulates immune responses and induces inflammation , anorexia and elevated body temperature, and also inhibits the gap junction protein connexin 43 in human corneal fibroblasts and causes corneal stromal damage.

Okadaic acid is a potent polyether marine toxin that accumulates in the digestive glands of marine mollusks.Okadaic acid is a highly potent and selective protein phosphatase (PP) inhibitor, inhibiting PP1, PP2A, PP3, PP4, and PP5.Okadaic acid activates Wnt β-catenin signaling in human HepaRG cells. catenin signaling in human HepaRG cells.
