Nordihydroguaiaretic acid induces heme oxygenase-1 (HO-1) and cytoprotection in a phosphatidyl inositol 3 kinase (PI3K)-dependent way in renal epithelial (LLC-PK1) cells
Nordihydroguaiaretic acid (NDGA) is an antioxidant phenolic lignan isolated from Larrea tridentata. NDGA induces heme oxygenase-1 (HO-1) in renal epithelial (LLC-PK1) cells and in murine embryonic fibroblasts (MEFs). The signaling pathways phosphatidyl inositol 3 kinase (PI3K)/Akt1, p38 and c-Jun N-terminal kinase (JNK) are involved in HO-1 induction in MEFs. The signaling pathway involved in HO-1 induction in...

Identification of compounds in hexane extracts of Elephantorrhiza elephantina and their comparison with selected over the counter products
The purpose of this study was to analyze hexane extracts of Elephantorrhiza elephantina(Ee) roots and to compare their chemical composition with some selected over the counter (OTC) products. Selection of the OTC products was based on their usage in treating stomach ailments, similar to the usage of E. elephantina in some regions of Southern Africa. A gas chromatography/mass spectrometer (GC/MS) and a...
