Non-alcoholic fatty liver disease and sleep disorders.

Studies have shown that non-alcoholic fatty liver disease (NAFLD) may be associated with sleep disorders. In order to explore the explicit relationship between the two, we systematically reviewed the effects of sleep disorders, especially obstructive sleep apnea (OSA), on the incidence of NAFLD, and analyzed the possible mechanisms after adjusting for confounding factors. NAFLD is independently associated with sleep disorders.

MAPK inhibitors protect against early‑stage osteoarthritis by activating autophagy.

Osteoarthritis (OA) is a chronic, age‑related osteoarthropathy that causes a considerable decline in quality of life, as well as economic losses due to its high incidence and poor prognosis. Mitogen‑activated protein kinases (MAPKs) regulate multiple cellular processes, including proliferation, differentiation and apoptosis, in certain diseases, such as cancer, diabetes and Alzheimer's disease. The present study aimed to investigate the regulatory role of the MAPK signaling pathway in early‑stage OA.

Endothelial cell-specific deficiency of the adenosine deaminase ADAR1 aggravates LPS-induced lung injury in mice via an MDA5-independent pathway.

Adenosine deaminase acting on RNA 1 (ADAR1) has been shown to participate in the regulation of endothelial cells (ECs), as well as local and systemic inflammatory responses. Here, we find that bacterial lipopolysaccharide (LPS)-induced upregulation of ADAR1 in lung ECs is impaired in aged mice, an animal model with high rates of sepsis and mortality. Endothelial cell-specific ADAR1 knockout (ADAR1 ) mice suffer from higher mortality rates, aggravated lung injury, and increased vascular permeability under LPS challenge.

RELA/NEAT1/miR-302a-3p/RELA feedback loop modulates pancreatic ductal adenocarcinoma cell proliferation and migration.

Pancreatic ductal adenocarcinoma (PDAC) remains a challenging malignancy due to distant metastasis. RELA, a major component of the NF-κB pathway, could serve as an oncogene through activating proliferation or migration-related gene expression, including NEAT1, a well-known oncogenic long noncoding RNA. In the current study, the expression and function of RELA and NEAT1 in PDAC were examined.
