General description

Fatty Acid-Albumin-complexes have been employed as alternative sources of lipids in the development of serum-free media. Fatty acids bind to serum proteins in high proportions. Such proteins may release beneficial fatty acids and bind those that are inhibitory. Oleic acid bound to bovine serum albumin (BSA) is beneficial to the growth of a variety of cell types (e.g., baby hamster kidney (BHK) hybridoma). A mixture of poly-unsaturated and monosaturated fatty acids (i.e., linoleic acid and oleic acid) produces synergistic effect when used as a media supplement.

Application

Linoleic Acid-Oleic Acid-Albumin, 100x has been used:
  • to induce acute hepatocellular stress in primary hepatocytes
  • to induce oxidative stress in cytotrophoblasts
  • to induce lipid droplet accumulation in HepG2 cells

Hepatocellular carcinoma (HCC) is one of the fastest-growing causes of cancer-related mortalities worldwide and this trend is mimicked by the surge of non-alcoholic fatty liver disease (NAFLD). Altered hepatic lipid metabolism promotes HCC development through inflammation and activation of oncogenes.

Generation of reactive oxygen species (ROS) in response to fatty acids accumulation has been classically proposed as a possible "second hit" triggering progression from simple steatosis to non-alcoholic steatohepatitis (NASH). In this study we challenged hepatocyte-specific Keap1 knockout mice (Keap1(Δhepa))
