Background: Osteoporosis (OP) is a systemic disease characterized by low bone mass. New progress has been made in the study of OP, such as lipid peroxidation. However, the role of lipid peroxides in osteoclast differentiation is still unclear.

Background: Neuregulin (NRG) family is involved in energy metabolism, among which NRG1 is a neuregulin proved to play a protective role in MAFLD cells. But the presice echanism has not been fully illustrated. This study aimed to investigate the role of NRG1 via the ERK/SIRT1 signaling in the pathogenesis of MAFLD.

Lipid accumulation in hepatocytes in non-alcoholic steatohepatitis (NASH) is attributed partly to loss of insulin-responsiveness and/or an increased pro-inflammatory state. Since the rare sugar D-allulose has insulin mimetic and anti-inflammatory properties, its effects on lipid accumulation in liver-derived cells was tested. In HepG2 cells exposed to 200 μM oleic acid for 72 h, D-allulose treatment decreased intracellular lipid accumulation with an IC = 0.

Objective: The authors explored differentially expressed circRNAs in Acute Ischemic Stroke (AIS) and revealed the role and potential downstream molecular mechanisms of circLOC375190.
Methods: circLOC375190 expression was modulated by lentiviral injection in the brain of transient Middle Cerebral Artery Occlusion (tMCAO) mice. Neurological dysfunction was assessed, as well as infarction size, histopathological changes, and neuronal apoptosis in tMCAO mice.
