Chaperone Hsp70 (HSPA1) Is Involved in the Molecular Mechanisms of Sleep Cycle Integration

Association between weekend catch-up sleep and depression in US adults

BACKGROUND

Depression is one of the most prevalent mental disorders and causes a serious economic and medical burden on society. This research assessed the correlation between weekend catch-up sleep (WCS) and depression in US adults aged ≥ 20 years.

METHODS

Cross-sectional data were obtained from individuals with complete WCS and Patient Health Questionnaire (PHQ-9) data who participated in the 2017-2020 National Health and Nutrition Examination Survey (NHANES). A logistic regression analysis was conducted to evaluate the possible independent conjunction between depression and WCS. Subgroup analysis and interaction tests have been carried out.

RESULTS

A total of 7,795 individuals with an average PHQ-9 level of 3.27 ± 4.25 were analyzed. The prevalence of depression was 9.11% overall, and participants in the quartile 3 (WCS 1-2 h) tended to have lowest rates of depression (Quartile 1: 9.49%; Quartile 2: 9.95%; Quartile 3: 7.03%; Quartile 4: 8.75%; p = 0.014). The incidence of depression was found to be less correlated with 1-2 h of WCS (OR = 0.74, 95% CI: 0.55, 0.99). Individuals with less than one hour or more than two hours of WCS did not have a significantly different risk of depression than individuals without WCS.

CONCLUSIONS

Moderate catch-up sleep on weekends was linked to a decreased likelihood of depression.

From sleep to cancer to neurodegenerative disease: the crucial role of Hsp70 in maintaining cellular homeostasis and potential therapeutic implications

Sleep is a fundamental process essential for reparatory and restorative mechanisms in all organisms. Recent research has linked sleep to various pathological conditions, including cancer and neurodegeneration, which are associated with various molecular changes in different cellular environments. Despite the potential significance of various molecules, the HSPA1A or Hsp70 protein, which has possible connections with sleep and different neuropsychological and pathological disorders, has been explored the least. This paper explores the potential for manipulating and discovering drugs related to the Hsp70 protein to alleviate sleep problems and improve the prognosis for various other health issues. This paper discusses the critical role of Hsp70 in cancer, neurodegeneration, apoptosis, sleep, and its regulation at the structural level through allosteric mechanisms and different substrates. The significant impact of Hsp70's connection to various conditions suggests that existing sleep medicine could be used to improve such conditions, leading to improved outcomes, minimized research costs, and a new direction for current research. Overall, this paper highlights the potential of Hsp70 protein as a key therapeutic target for developing new drugs for the treatment of sleep disorders, cancer, neurodegeneration, and other related pathological conditions. Further research into the molecular mechanisms of Hsp70 regulation and its interactions with other cellular pathways is necessary to develop targeted treatments for these conditions.Communicated by Ramaswamy H.
