Journal: Fluorometholone inhibits high glucose-induced cellular senescence in human retinal endothelial cells. (Pubmed Central) - Mar 23, 2022 Lastly, the protective effects of FML against high glucose-induced cellular senescence in HRECs were abolished by the co-treatment of the PI3K/Akt signaling inhibitor LY294002, suggesting the involvement of this pathway. Taken together, these data revealed that FML-inhibited high glucose-induced cellular senescence mediated by Akt in HERCs, suggesting a novel molecular mechanism of FML.

Journal: Inhibition of PI3K/AKT/mTOR Signalling Pathway Activates Autophagy and Suppresses Peritoneal Fibrosis in the Process of Peritoneal Dialysis. (Pubmed Central) - Mar 23, 2022 In this experiment, a high-glucose (HG)-induced peritoneal fibrosis rat model was successfully established via intraperitoneal injection of HG peritoneal dialysate, and the phosphatidylinositol 3-kinase (PI3K) inhibitor LY294002 and the mechanistic target of rapamycin (mTOR) inhibitor rapamycin were used to treat peritoneal fibrosis rats...The current data indicated that inhibition of PI3K/AKT/mTOR signalling pathway activated autophagy and suppressed PF in the process of PD. Therefore, intervention in this signalling pathway may become a research goal for the prevention and treatment of PF, which has important clinical significance.

Journal: Dual efficacy of Fasudil at improvement of survival and reinnervation of flap through RhoA/ROCK/PI3K/Akt pathway. (Pubmed Central) - Mar 23, 2022 As for reinnervation, Neurofilament-200 fluorescent staining revealed that at days 15 and 30 after flap harvest, only in the Fasudil group could new axons be observed. It can be concluded that Fasudil could simultaneously improve the survival and axon growth after flap harvest, a dual efficacy achieved by inhibition of the RhoA/ROCK pathway, which in turn activates /PI3K/AKT pathway.

Journal, IO biomarker: Protection of Human Lens Epithelial Cells from Oxidative Stress Damage and Cell Apoptosis by KGF-2 through the Akt/Nrf2/HO-1 Pathway. (Pubmed Central) - Mar 18, 2022 LY294002, the phosphatidylinositol-3-kinase (PI3K)/Akt inhibitor, abolished KGF-2's effect to some extent, demonstrating that KGF-2 protected HLECs via the PI3K/Akt pathway...Furthermore, as revealed by lens organ culture assays, KGF-2 treatment decreased HO-induced lens opacity in a concentration-dependent manner. As demonstrated by these data, KGF-2 resisted HO-mediated apoptosis and oxidative stress in HLECs through Nrf2/HO-1 and PI3K/Akt pathways, suggesting a potential protective effect against the formation of cataracts.

Journal: mTOR regulates cocaine-induced behavioural sensitization through the SynDIG1-GluA2 interaction in the nucleus accumbens. (Pubmed Central) - Mar 17, 2022 In this study, we showed that mTOR signaling was activated during the expression of behavioral sensitization to cocaine and that intraperitoneal or intra-nucleus accumbens (NAc) treatment with rapamycin, a specific mTOR inhibitor, attenuated cocaine-induced behavioural sensitization...The behavioural effect of cocaine was attenuated by intra-NAc administration of LY294002, an AKT-specific inhibitor, suggesting that PIPs may contribute to mTOR activation in response to cocaine...In contrast, AAV-mediated SynDIG1 overexpression in NAc attenuated intracellular GluA2 internalization by promoting the SynDIG1-GluA2 interaction, thus maintaining GluA2 surface expression and repressing cocaine-induced behaviours. In conclusion, NAc SynDIG1 may play a negative regulatory role in cocaine-induced behavioural sensitization by regulating synaptic surface expression of GluA2.

Journal: Cross-regulation of notch/AKT and serum/glucocorticoid regulated kinase 1 (SGK1) in IL-4-stimulated human macrophages. (Pubmed Central) - Mar 16, 2022 To dissect the signaling pathway leading to SGK1 upregulation, we pretreated THP-1-derived macrophages with specific inhibitors of Notch (DAPT), AKT (LY294002) or ERK (U0126)...Finally, GSK650394 treatment of human M(IL-4) increased the levels of PPARG mRNA and its protein, indicating a negative role of SGK1 in M(IL-4) function. Overall, we report that the Notch signaling and AKT pathways cooperatively regulate SGK1 expression in M(IL-4) where SGK1, in turn, plays an important role in suppressing IL-4-induced PPAR expression.

Preclinical, Journal: Calcium-Prolactin Secretion Coupling in Rat Pituitary Lactotrophs Is Controlled by PI4-Kinase Alpha. (Pubmed Central) - Mar 15, 2022 Wortmannin, a PI3K and PI4K inhibitor, but not LY294002, a PI3K inhibitor, blocked spontaneous action potential driven PRL release with a half-time of ~20 min when applied in 10 µM concentration, leading to accumulation of intracellular PRL content...In contrast, PIK93, a specific inhibitor of PI4KB, and ISA2011B and UNC3230, specific inhibitors of PIP5K1A and PIP5K1C, respectively, did not affect PRL release. These experiments revealed a key role of PI4KA in calcium-secretion coupling in pituitary lactotrophs downstream of voltage-gated and PI(4, 5)P2-dependent calcium signaling.

Journal: Calycosin as a Novel PI3K Activator Reduces Inflammation and Fibrosis in Heart Failure Through AKT-IKK/STAT3 Axis. (Pubmed Central) - Mar 11, 2022 In the in vitro experiments, the phosphatidylinositol three kinase (PI3K) inhibitor LY294002 could abrogate the anti-inflammation and antifibrosis therapeutic effects of Cal, demonstrating that the cardioprotective effects of Cal were mediated through upregulations of PI3K and serine/threonine kinase (AKT). Cal inhibited inflammation and fibrosis via activation of the PI3K-AKT pathway in H9C2 cells, fibroblasts, and heart failure in postacute myocardial infarction rats.

Journal, IO biomarker: Panax notoginseng saponins induce apoptosis in retinoblastoma Y79 cells via the PI3K/AKT signalling pathway. (Pubmed Central) - Mar 5, 2022 The effects of PNS and carboplatin on the proliferation of Y79 cells were examined using cell counting kit-8 assay...Cellular alterations following inhibition of the PI3K/AKT pathway using LY294002 were similar to those of PNS, the proliferation of Y79 cells was also inhibited, and cell apoptosis increased (P < 0.001)...Overall, we demonstrated that PNS effectively inhibited the proliferation and promoted the apoptosis of retinoblastoma Y79 cells. The apoptosis-promoting effect of PNS may involve the inhibition of the PI3K/AKT signalling pathway, which subsequently regulates the expression of apoptosis-related genes.

(Pubmed Central) - Mar 5, 2022 Notably, the present study demonstrated that verteporfin mediated the suppression of migration and invasion of DLD-1 cells due to the decreased expression of YAP. Therefore, targeting YAP may be valuable for developing therapeutic strategies against CRC, and verteporfin may be an effective therapy to suppress the migration and invasion of CRC.

Journal: Assessment of tantalum nanoparticle-induced MC3T3-E1 proliferation and underlying mechanisms. (Pubmed Central) - Mar 4, 2022 Taken together, these results indicate that Peoniflorin preconditioning protects the myocardial against I/R injury and inhibits myocardial apoptosis via the activation of the RISK pathway, highlighting the potential therapeutic effects of Peoniflorin on reducing myocardial I/R injury. Pretreatment with Triciribine or Rapamycin has a greater effect on pathway protein Akt, cell cycle arrest, autophagy protein, and cell proliferation but with inconsistent magnitude, which may be inferred that the Akt/mTOR pathway, as well as its feedback loop, were more likely involved in these processes.

Journal: Calycosin alleviates H O -induced astrocyte injury by restricting oxidative stress through the Akt/Nrf2/HO-1 signaling pathway. (Pubmed Central) - Mar 3, 2022 Furthermore, calycosin failed to increase Akt phosphorylation and mitigate H O -induced astrocyte damage in the presence of the LY294002 (a selective phosphatidylinositol 3-kinase inhibitor), indicating that calycosin-mediated regulation of oxidative-stress homeostasis involved Akt/Nrf2/HO-1 signaling. These findings demonstrated that calycosin protects against oxidative injury in brain astrocytes by regulating oxidative stress through the AKT/Nrf2/HO-1 signaling pathway.

It is proposed that chemerin plays a role in the pathogenesis of cardiac diseases.
