Patulin triggers NRF2-mediated survival mechanisms in kidney cells.
Patulin (PAT), a mycotoxin contaminant of apples and apple products, has been implicated in nephrotoxicity. PAT depletes glutathione (GSH) and elevates reactive oxygen species (ROS). The antioxidant (AO) response is activated by Nuclear erythroid 2-related factor (NRF2) and enhanced by Silent information regulator 3 (SIRT3). The effects of PAT on these molecules have yet to be examined. We inve...
متن کاملMolecular mechanisms of Nrf2-mediated antioxidant response.
Nrf2 is the key transcription factor regulating the antioxidant response. Nrf2 signaling is repressed by Keap1 at basal condition and induced by oxidative stress. Keap1 is recently identified as a Cullin 3-dependent substrate adaptor protein. A two-sites binding "hinge & latch" model vividly depicts how Keap1 can efficiently present Nrf2 as substrate for ubiquitination. Oxidative perturbation c...
متن کاملEvolvulus alsinoides methanolic extract triggers apoptosis in HepG2 cells
Objective: The objective of the present study was to evaluate the cytotoxic potentials of Evolvulus alsinoides in human hepatoma HepG2 cells. Materials and Methods: HepG2 cells were treated with methanolic extract of E. alsinoides at 20, 40 and 80 µg/ml for 24 hr and cytotoxic effect was analyzed by MTT assay. The apoptosis rate was investigated by Hoechst 33342 and annexin V/propidium iodide s...
متن کاملMycotoxin patulin activates the p38 kinase and JNK signaling pathways in human embryonic kidney cells.
Patulin (PAT), a mycotoxin mainly produced by Penicillium and Aspergillus, is frequently detected in moldy fruits and fruit products. Exposure of human embryonic kidney (HEK293) cells to PAT led to a dose- and time-dependent increase in the phosphorylation of two major mitogen-activated protein kinases (MAPKs), p38 kinase and c-Jun N-terminal kinase (JNK). The phosphorylated forms of MAPK kinas...
متن کاملEndothelial Cells in Antibody-Mediated Rejection of Kidney Transplantation: Pathogenesis Mechanisms and Therapeutic Implications
Antibody-mediated rejection (AMR) has been identified as a main obstacle for stable immune tolerance and long survival of kidney allografts. In spite of new insights into the underlying mechanisms of AMR, accurate diagnosis and efficient treatment are still challenges in clinical practice. Endothelium is the first barrier between recipients' immune systems and grafts in vascularized organ trans...
