Based on 1 Customer Validation
Nodularin is a hepatotoxin, tumor promoter, and protein phosphatase inhibitor. Nodularin induces apoptosis (apoptosis) in normal cells (including caspase activation, upregulation of Bcl-XS, and upregulation of BAX/P53), triggers hyperphosphorylation of the MAPK/ERK, mTOR/S6K and p38 MAPK signaling pathways, and induces oxidative stress, endoplasmic reticulum membrane instability, peroxisome proliferation and increased lysosomal enzyme activity. Nodularin promotes DEN (HY-N7434)-initiated hepatocyte proliferation and adenoma formation, and inhibits proliferation, phagocytosis and chemotaxis of normal lymphocytes, oocyte maturation and vitellogenesis, as well as angiogenesis. Nodularin exhibits hepatotoxicity, reproductive and endocrine toxicity, and embryonic developmental toxicity in various animal models. Nodularin can be used in studies related to liver cancer, hepatotoxicity and reproductive endocrine toxicity.

Cell Cycle Regulation
Nodularin (25 µg/kg; intraperitoneal injection; twice a week; for 10 consecutive weeks) acts as a tumor promoter during DEN-induced hepatocarcinogenesis in male F344/KIST rats. It induces sustained proliferation of GST-P-positive dense nodules, while causing transient proliferation of background hepatocytes, and this proliferation returns to the level of the control group after treatment cessation[1].
Lysosomal Metabolism
Endoplasmic Reticulum Stress
A single intraperitoneal administration of Nodularin (8 μg/kg) causes a statistically significant increase in the activities of hepatic β-D-glucuronidase, α-glucosidase, lysosomal esterase and N-acetylglucosaminidase in multiple cellular fractions within 24 h, with the peak effect typically occurring at 30 min post-administration, and also induces endoplasmic reticulum membrane instability[2].
Oxidative Stress
Nodularin (2.5-10 μg/L; waterborne exposure; continuous exposure for 14 days) disrupts the reproductive endocrine system of female zebrafish by reducing the levels of gonadotropins and E2, increasing T levels, altering oocyte development, inducing oxidative stress, and regulating gene expression in the hypothalamic-pituitary-gonadal-liver axis[3].
Oxidative Stress
Apoptosis
Local Vascular Regulation
Anti-cancer
Apoptosis
Nodularin (25 μg/kg; i.p.; twice a week; for 10 consecutive weeks) induces selective atrophy of the left and caudal liver lobes in normal saline-pretreated F344 rats through sustained inhibition of PP1/PP2A, peroxisome proliferation, and induction of the pro-apoptotic protein Bcl-Xs, while promoting enlargement of the right and middle liver lobes via upregulation of the anti-apoptotic protein Bcl-Xl[10].
Anti-cancer
Nodularin (25 μg/kg; i.p.; twice a week; for 10 consecutive weeks) promotes hepatocyte proliferation and adenoma formation in DEN (HY-N7434)-induced F344 rats by restoring PP1/PP2A activity, promoting peroxisome proliferation, maintaining the expression of the anti-apoptotic protein Bcl-XL, and simultaneously blocking hepatic lobe atrophy[10].
