Metformin reverses oxidative stress ‑induced mitochondrial dysfunction in pre‑osteoblasts via the EGFR/GSK‑3β/calcium pathway
Int J Mol Med. 2023 Apr;51(4):36. doi: 10.3892/ijmm.2023.5239. Epub 2023 Mar 31.ABSTRACTOxidative stress is one of the main causes of osteoblast apoptosis induced by post‑menopausal osteoporosis. The authors previously found that metformin can reverse the loss of bone mass in post‑menopausal osteoporosis. The present study aimed to further clarify the effects and mechanisms of action of metformin in post‑menopausal osteoporosis under conditions of oxidative stress. Combined with an in‑depth investigation using the transcriptome database, the association between oxidative stress and mitochondrial dysfunction in post...

Hesperetin ameliorates spinal cord injury by inhibiting NLRP3 inflammasome activation and pyroptosis through enhancing Nrf2 signaling
Int Immunopharmacol. 2023 Mar 28;118:110103. doi: 10.1016/j.intimp.2023.110103. Online ahead of print.ABSTRACTNeuroinflammation is a prominent feature of traumatic spinal cord injuries (SCIs). Hesperetin exhibits anti-inflammatory effects in neurological disorders; however, the potential neuroprotective effects of hesperetin in cases of SCI remain unclear. Sprague-Dawley rats with C5 hemi-contusion injuries were used as an SCI model. Hesperetin was administered to the experimental rats in order to investigate its neuroprotective effects after SCI, and BV2 cells were pretreated with hesperetin or silencing of nuclear factor...

Chronic suppression of STIM1-mediated calcium signaling in Purkinje cells rescues the cerebellar pathology in spinocerebellar ataxia type 2
Biochim Biophys Acta Mol Cell Res. 2023 Mar 18:119466. doi: 10.1016/j.bbamcr.2023.119466. Online ahead of print.ABSTRACTDistorted neuronal calcium signaling has been reported in many neurodegenerative disorders, including different types of spinocerebellar ataxias (SCAs). Cerebellar Purkinje cells (PCs) are primarily affected in SCAs and the disturbances in the calcium homeostasis were observed in SCA PCs. Our previous results have revealed that 3,5-dihydroxyphenylglycine (DHPG) induced greater calcium responses in SCA2-58Q PC cultures than in wild type (WT) PC cultures. Here we observed that glutamate-induced calcium rele...

N protein of PEDV plays chess game with host proteins by selective autophagy
In this study, we have found a novel host restriction factor, HNRNPA1, that could inhibit PEDV replication by degrading viral nucleocapsid (N) protein. The restriction factor activates the HNRNPA1-MARCHF8/MARCH8-CALCOCO2/NDP52-autophagosome pathway with the help of transcription factor EGR1 targeting the HNRNPA1 promoter. HNRNPA1 could also promote the expression of IFN to facilitate the host antiviral defense response for antagonizing PEDV infection through RIGI protein interaction. During viral replication, we found that PEDV can, in contrast, degrade the host antiviral proteins HNRNPA1 and others (FUBP3, HNRNPK, PTBP1, ...
