ABSTRACT
Background:
Glutamate is one
of the most important excitatory neurotransmitters released by nerve cells in the
brain. Glutamate homoeostasis is essential for the regular functioning of the
brain's functions. The literature has reported that high concentrations of
glutamate are associated with diseases such as Parkinson's disease, Alzheimer's
disease and Huntington's disease. Chrysin is a flavonoid in many plant extracts
and renewable substances such as mushrooms, honey, and propolis. It has also
been reported that chrysin has anti-inflammatory, anti-cancer and
anti-oxidation properties. Aim: In
our literature review, no study was found on the protective effect of chrysin
in C6 glioma cells exposed to high glutamate concentrations. This study
investigated the effect of chrysin against glutamate-induced excitotoxicity in
C6 glioma cells. Methods: For the
study, groups were formed from C6 cells as control, chrysin (50 μM, 24 h),
Glutamate (10 mM, 24 h), and Glutamate+Chrysin. At the end of the study, total
oxidant level (TOS), total antioxidant level (TAS), TNF-α, IL-1β, caspase-3 and
caspase-9 levels in cells were measured with an ELISA kit. Results: It was observed
that exposure to high-dose glutamate (10 mM) in C6 cells increased TOS, TNF-α,
IL-1β, caspase-3 and caspase-9, and decreased TAS levels (p<0.05). Furthermore,
in the chrysin treatment group (Glutamate+Chrysin group), it was determined
that, compared to the glutamate group, the chrysin increased TAS levels in
cells and decreased TOS, TNF-α, IL-1β, caspase-3, and caspase-9 levels
(p<0.05). Discussion and Conclusion:
As a result, it was observed that chrysin has a protective effect on
glutamate-induced excitotoxicity in the C6 cells. This study showed us that
chrysin might be a protective factor in excitotoxic neuronal damage caused by
glutamate.
