Melatonin attenuates D‐galactose‐induced memory impairment, neuroinflammation and neurodegeneration via RAGE/NF‐KB/JNK signaling pathway in aging mouse model
Abstract
Melatonin acts as a pleiotropic agent in various age‐related neurodegenerative diseases. In this study, we examined the underlying neuroprotective mechanism of melatonin against D‐galactose‐induced memory and synaptic dysfunction, elevated reactive oxygen species (ROS), neuroinflammation and neurodegeneration. D‐galactose was administered (100 mg/kg intraperitoneally (i.p.)) for 60 days. After 30 days of D‐galactose administration, vehicle (same volume) or melatonin (10 mg/kg, i.p.) was administered for 30 days. Our behavioral (Morris water maze and Y‐maze test) results revealed that chronic melatonin treatment alleviated D‐galactose‐induced memory impairment. Additionally, melatonin treatment reversed D‐galactose‐induced synaptic disorder via increasing the level of memory‐related pre‐and postsynaptic protein markers. We also determined that melatonin enhances memory function in the D‐galactose‐treated mice possibly via reduction of elevated ROS and receptor for advanced glycation end products (RAGE). Furthermore, Western blot and morphological results showed that melatonin treatment significantly reduced D‐galactose‐induced neuroinflammation through inhibition of microgliosis (Iba‐1) and astrocytosis (GFAP), and downregulating other inflammatory mediators such as p‐IKKβ, p‐NF‐K B 65, COX 2, NOS 2, IL‐1 β, and TNFα. Moreover, melatonin lowered the oxidative stress kinase p‐JNK which suppressed various apoptotic markers, that is, cytochrome C, caspase‐9, caspase‐3 and PARP‐1, and prevent neurodegeneration. Hence, melatonin attenuated the D‐galactose‐induced memory impairment, neuroinflammation and neurodegeneration possibly through RAGE/NF‐K B/JNK pathway. Taken together, our data suggest that melatonin could be a promising, safe and endogenous compatible antioxidant candidate for age‐related neurodegenerative diseases such as Alzheimer's disease (AD).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
