Dapagliflozin alleviates cardiac fibrosis through suppressing EndMT and fibroblast activation via AMPK α/TGF-β/Smad signalling in type 2 diabetic rats
This study aimed to evaluate the effect of SGLT2 inhibitor dapagliflozin (DAPA) on DCM especially for cardiac fibrosis and explore the underlying mechanism. In vivo, the model of type 2 diabetic rats was built with high-fat feeding and streptozotocin injection. Untreated diabetic rats showed cardiac dysfunction, increased myocardial fibrosis and EndMT, which was attenuated after treatment with DAPA and metformin. In vitro, HUVECs and primary cardiac fibroblasts were treated with DAPA and exposed to high glucose (HG). HG-induced EndMT in HUVECs and collagen secretion of fibroblasts were markedly inhibited by DAPA. Up-regula...

Activated AMPK by metformin protects against fibroblast proliferation during pulmonary fibrosis by suppressing FOXM1
Pharmacol Res. 2021 Aug 24:105844. doi: 10.1016/j.phrs.2021.105844. Online ahead of print.ABSTRACTPulmonary fibrosis (PF) is a progressive and devastating lung disease of unknown etiology, excessive fibroblast proliferation serves as a key event to promote PF. Transcription factor forkhead box M1 (FOXM1) is not only a well-known proto-oncogene, but also an essential driver of cell proliferation. Recently, 5'-AMP-activated protein kinase (AMPK) is reported to reduce the incidence of PF. However, it remains elusive whether have an underlying relationship between AMPK and FOXM1 in fibroblast proliferation-mediated PF. Here, t...

Metformin alleviates the calcification of aortic valve interstitial cells through activating the PI3K/AKT pathway in an AMPK dependent way
CONCLUSIONS: This study, for the first time, demonstrates that metformin can inhibit AVICs in vitro calcification by activating the PI3K/AKT signaling pathway; this suggests that metformin may provide a potential target for the treatment of CAVD. And the PI3K/AKT signaling pathway emerges as an important regulatory axis in the pathological mechanism of CAVD.PMID:34895136 | DOI:10.1186/s10020-021-00416-x

Changes in AMPK activity induces cellular senescence in human dental follicle cells
This study examined the role of AMPK in inducing senescence in DFCs. During the induction of cellular senescence, AMPK activity was impaired, suggesting a negative impact on senescence induction. In line with this assumption, cellular senescence was induced upon inhibition of AMPK with a specific siRNA. In addition, after this inhibition, autophagy was also inhibited. Moreover, specific inhibition of autophagy promoted cellular senescence. However, inducers of AMPK such as metformin or AICAR surprisingly increased senescence in DFCs. Interestingly, autophagy was impaired after long-term induction of AMPK with AICAR and met...

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...

Metformin protects against retinal ischemia/reperfusion injury through AMPK-mediated mitochondrial fusion
This study aims to evaluate the protective effect of metformin against retinal I/R injury and its underlying mechanism. I/R induced reduction in retina thickness and cell number in ganglion cell layer, and metformin alleviated I/R-induced retinal injury. Both retinal I/R and simulated ischemia/reperfusion (SIR) in R28 cells down-regulated expression of mitochondrial fusion protein Mfn2 and OPA1, which led to mitochondrial fission. Metformin also alleviated damage in R28 cells, and reversed the alteration in Mfn2 and OPA1, mitochondrial fission and mitochondrial membrane potential (MMP) disruption-induced by I/R or SIR as w...

Hyperglycaemia aggravates periodontal inflamm-aging by promoting SETDB1-mediated LINE-1 de-repression in macrophages
CONCLUSIONS: The findings of this study show that SETDB1 regulates senescence-like phenotypical switching of macrophages and is a potential candidate for the treatment of diabetes-induced periodontal inflamm-aging.PMID:37661095 | DOI:10.1111/jcpe.13871
