“…SPB pretreatment prevented the GRP78 elevation in the HC region, thereby abate the neuroinflammation. A previous study demonstrated that corticosterone administration can increase the ER stress-related proteins (GRP78 and GRP94) in the HC region [54]. Therefore, in the present study, we examined the serum corticosterone level 24 h after LPS administration.…”

Oxido-nitrosative stress, neuroinflammation, and reduced level of neurotrophins are implicated in the pathophysiology of anxiety and depressive illness. A few recent studies have revealed the role of endoplasmic reticulum (ER) stress in the pathophysiology of stress and depression. The aim of the present study is to investigate the neuroprotective potential of sodium phenylbutyrate (SPB), an ER stress inhibitor against lipopolysaccharide (LPS)-induced anxiety and depressive-like behavior in Swiss albino mice. Anxiety and depressive-like behavior was induced by LPS (0.83 mg/kg; i.p.) administration. Various behavioral tests were conducted to evaluate the anxiety and depressive-like behavior in mice. Real-time PCR was employed for the detection and expression of ER stress markers (78-kDa glucose-regulated protein (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP)). Pretreatment with SPB significantly ameliorated the LPS-induced anxiety and depressive-like behavior as revealed by behavioral paradigm results. LPS-induced oxidative stress was ameliorated by SPB pretreatment in hippocampus (HC) and prefrontal cortex (PFC) region. Neuroinflammation was significantly reduced by SPB pretreatment in LPS-treated mice as evident from reduction in proinflammatory cytokines (IL-1β and TNF-α). Importantly, LPS administration significantly up-regulated the GRP78 mRNA expression level in the HC which suggests the involvement of unfolded protein response (UPR) in LPS-evoked behavioral anomalies. These results highlight the neuroprotective potential of SPB in LPS-induced anxiety and depressive illness model which may be partially due to inhibition of oxidative stress-neuroinflammatory cascade.

“…It has been reported that luteolin significantly suppressed Tm-induced caspase-3 activation without changing Tm-induced CHOP or GRP78 expression in SH-SY5Y neuroblastoma cells [66]. We thus investigated how luteolin and apigenin affect Tm-induced cytotoxicity and ER stress gene expression in PC12 cells.…”

Luteolin and apigenin are dietary flavones and exhibit a broad spectrum of biological activities including antioxidant, anti-inflammatory, anti-cancer and neuroprotective effects. The lipid peroxidation product 4-hydroxy-2-nonenal (4-HNE) has been implicated as a causative agent in the development of neurodegenerative disorders. This study investigates the cytoprotective effects of luteolin and apigenin against 4-HNE-mediated cytotoxicity in neuronal-like catecholaminergic PC12 cells. Both flavones restored cell viability and repressed caspase-3 and PARP-1 activation in 4-HNE-treated cells. Luteolin also mitigated 4-HNE-mediated LC3 conversion and reactive oxygen species (ROS) production. Luteolin and apigenin up-regulated 4-HNE-mediated unfolded protein response (UPR), leading to an increase in endoplasmic reticulum chaperone GRP78 and decrease in the expression of UPR-targeted pro-apoptotic genes. They also induced the expression of Nrf2-targeted HO-1 and xCT in the absence of 4-HNE, but counteracted their expression in the presence of 4-HNE. Moreover, we found that JNK and p38 MAPK inhibitors significantly antagonized the increase in cell viability induced by luteolin and apigenin. Consistently, enhanced phosphorylation of JNK and p38 MAPK was observed in luteolin- and apigenin-treated cells. In conclusion, this result shows that luteolin and apigenin activate MAPK and Nrf2 signaling, which elicit adaptive cellular stress response pathways, restore 4-HNE-induced ER homeostasis and inhibit cytotoxicity. Luteolin exerts a stronger cytoprotective effect than apigenin possibly due to its higher MAPK, Nrf2 and UPR activation, and ROS scavenging activity.

In the present study, we investigated whether blue light emission diode (LED) light exposure affects the maternal behavior of mice. The brain function of the offspring mice, including short-term memory, locomotor activity, anxiety-like behavior, and depression-like behavior, was evaluated. Pregnant mice at day 11 were housed in the apparatus for exposure to blue LED light during the daytime. Nesting behavior and the survival of pups were observed until weaning. After weaning, the offspring mice were bred in normal light conditions until 12 weeks old, and then the Y-maze test, open field test, and tail suspension test were performed. Retinal functions were evaluated by electroretinogram and histological analysis. Blue LED light exposure during the daytime induced retinal damage, but did not affect behavior related to maternal care in maternal mice. In the offspring mice, blue LED light exposure during the daytime did not affect the retina or brain functions. These findings suggest that blue LED light during the daytime might not be a risk factor for disruption of the mother-infant relationship or offspring brain development in mice.
