Gamma-Linolenic acid
Based on 8 publication(s) in Google Scholar
Gamma-linolenic acid (γ-Linolenic acid) is an orally active unsaturated fatty acid. Gamma-linolenic acid exerts anti-inflammatory effects by inhibiting the NF-κB pathway and the phosphorylation of ERK1/2 and JNK. At the same time, it exerts anticancer effects by inducing apoptosis (Apoptosis) in cancer cells. Additionally, Gamma-linolenic acid also has antioxidant and memory-improving effects. It holds promise for research in the fields of inflammation, neurology, and cancer diseases.

Gamma-linolenic acid (10-100 μM, 24 h) can protect PC12 cells from β-Amyloid (25-35) (HY-P0128)-induced damage by alleviating oxidative stress, restoring cell cycle arrest, and blocking caspase-3 activation in PC12 cells[2]. Gamma-linolenic acid (10-100 μM, 24 h) ameliorates β-Amyloid (25-35) (HY-P0128)-induced neuroinflammation in PC12 cells by inhibiting NF-κB and MAPK signaling pathways[2]. Gamma-linolenic acid (100μM, 2 days) inhibits the proliferation and migration of human and rat GBM cells and induces apoptosis in human and rat GBM cells[3].
