ABSTRACT
BACKGROUND:
The prevalence of obesity is growing rapidly and has become a global problem that increases the risk for many diseases. It is influenced by many factors, including consumption of the Western-style diet, characterized as a high-fat diet. Within the central nervous system, the hypothalamus is a critical site in maintaining energy homeostasis and sensing nutrient status, including palmitate, the major component of high-fat-diet.METHODS:
In the present study, we conducted a variety of studies to investigate the specific role of salubrinal on palmitate-induced hypothalamic cell death, leptin signaling, and ER stress in an embryonic hypothalamic cell line. Experiments were also performed to identify the underlying mechanisms of the protective effect of salubrinal.RESULTS:
Our results indicate that salubrinal protects hypothalamic cells against PA-induced ER stress and improves hypothalamic leptin sensitivity.CONCLUSION:
Taken together, our findings conclusively reveal that salubrinal abrogates palmitate-induced hypothalamic leptin resistance and ER stress via NF-κB pathway.
