  • ||||||||||  Preclinical, Journal, IO biomarker:  Paeonol inhibits proliferation and induces cell apoptosis of human T24 and 5637 bladder cancer cells in vitro and in vivo. (Pubmed Central) -  Sep 16, 2021   
    Results from the current study suggest composite biomarkers created from multi-parametric MR-PET imaging targeting metabolic and/or physiologic processes specific to the drug mechanism of action may be useful for subsequent evaluation of treatment efficacy for larger phase II-III studies. We confirmed that paeonol could inhibit proliferation and induce apoptosis of human bladder cancer T24 and 5637 cells in vitro and in vivo, inhibit the growth of T24 tumor-forming nude mice, and possibly play a role by inhibiting the PI3K/AKT signaling pathway, so as to provide a potential therapeutic drug for bladder cancer.

    Journal:  S-oxiracetam Facilitates Cognitive Restoration after Ischemic Stroke by Activating α7nAChR and the PI3K-Mediated Pathway. (Pubmed Central) -  Sep 16, 2021   
    Furthermore, we found that methyllycaconitine, the antagonist of α7 nicotinic acetylcholine receptor (α7nAChR), and LY294002, the inhibitor of phosphoinositide 3-kinase (PI3K), were able to block the cognitive effects of S-ORC after MCAO/R in rats. In conclusion, α7nAChR and PI3K are key molecules that mediated the signaling pathway leading to S-ORC-induced cognitive restoration after MCAO/R.

    Journal:  GLI1 reduces drug sensitivity by regulating cell cycle through PI3K/AKT/GSK3/CDK pathway in acute myeloid leukemia. (Pubmed Central) -  Sep 16, 2021   
    Notably, the GLI1 inhibitor GANT61 and the CDK4/6 inhibitor PD 0332991 had synergistic effects in promoting Ara-c sensitivity in AML cell lines and patient samples. Collectively, our data demonstrate that GLI1 reduces drug sensitivity by regulating cell cycle through the PI3K/AKT/GSK3/CDK pathway, providing a new perspective for involving GLI1 and CDK4/6 inhibitors in relapsed/refractory (RR) patient treatment.

    Journal:  METTL14-regulated PI3K/Akt signaling pathway via PTEN affects HDAC5-mediated epithelial-mesenchymal transition of renal tubular cells in diabetic kidney disease. (Pubmed Central) -  Sep 15, 2021   
    Furthermore, HDAC5 expression was regulated by PI3K/Akt signaling pathway and inhibition of PI3K/Akt pathway by LY294002 treatment or Akt phosphorylation mutation reduced HDAC5 and TGF-β1 expression in vitro high glucose-cultured HK2 cells...Finally, in vivo HDACs inhibitor TSA treatment alleviated extracellular matrix accumulation in kidneys of diabetic mice, accompanied with HDAC5, TGF-β1, and α-SMA expression downregulation. These above data suggest that METTL14-regulated PI3K/Akt signaling pathway via PTEN affected HDAC5-mediated EMT of renal tubular cells in diabetic kidney disease.
  • ||||||||||  Journal:  PER1 suppresses glycolysis and cell proliferation in oral squamous cell carcinoma via the PER1/RACK1/PI3K signaling complex. (Pubmed Central) -  Sep 15, 2021   
    In vivo tumorigenicity assays confirmed that PER1 overexpression inhibited tumor growth while suppressing glycolysis, proliferation, and the PI3K/AKT pathway. Collectively, this study generated the novel findings that PER1 suppresses OSCC progression by inhibiting glycolysis-mediated cell proliferation via the formation of the PER1/RACK1/PI3K complex to regulate the stability of PI3K and the PI3K/AKT pathway-dependent manner and that PER1 could potentially be a valuable therapeutic target in OSCC.

    Journal:  Exosome-mediated transfer of MIF confers temozolomide resistance by regulating TIMP3/PI3K/AKT axis in gliomas. (Pubmed Central) -  Sep 14, 2021   
    Additionally, exosomal MIF promoted tumor growth and TMZ resistance of glioma cells in vivo, while IOS-1 (MIF inhibitor) promotes glioma TMZ sensitive in vivo. Taken together, our study demonstrated that exosome-mediated transfer of MIF enhanced TMZ resistance in glioma through downregulating TIMP3 and further activating the PI3K/AKT signaling pathway, highlighting a prognostic biomarker and promising therapeutic target for TMZ treatment in gliomas.
  • ||||||||||  Review, Journal:  Signalling transduction of O-GlcNAcylation and PI3K/AKT/mTOR-axis in prostate cancer. (Pubmed Central) -  Sep 12, 2021   
    Inhibition of these multiple pathways at their common junctures might prove to be of benefit in men suffering from an advanced disease state. Hence, a thorough understanding of these cellular intersecting points and their significance with respect to signal transduction mechanisms might assist in the rational designing of combinations for effective management of prostate cancer.
  • ||||||||||  Review, Journal:  Targeting PI3K Pathway in Pancreatic Ductal Adenocarcinoma: Rationale and Progress. (Pubmed Central) -  Sep 11, 2021   
    Here, we discuss the significance of targeting PI3K signaling and the biological impact of PI3K inhibition in modulating the tumor-stromal immune crosstalk within the microenvironment of pancreatic cancer. Furthermore, this review updates on the current challenges involving the therapeutic implications of targeting this pathway in PDAC.

    Journal:  Maresin-1 induces cardiomyocyte hypertrophy through IGF-1 paracrine pathway. (Pubmed Central) -  Sep 11, 2021   
    These data indicate that MaR1 induces cardiomyocyte hypertrophy through RORα/IGF-1/PI3K/Akt pathway. Considering that MaR1 is a potent resolving factor, MaR1 could be a key mediator that orchestrates the resolution of inflammation with myocardial repair.

    Journal:  Extracellular HSP90α Interacts With ER Stress to Promote Fibroblasts Activation Through PI3K/AKT Pathway in Pulmonary Fibrosis. (Pubmed Central) -  Sep 10, 2021   
    In addition, eHSP90α induced ER stress in fibroblasts via the phosphoinositide-4,5-bisphosphate 3-kinase (PI3K)-protein kinase B (AKT) signaling pathway, which could be blocked by the PI3K/AKT inhibitor LY294002, and blockade of eHSP90α by 1G6-D7 markedly inhibited ER stress in the model, indicating preventive and therapeutic applications...In conclusion, this study shows that the interaction between eHSP90α and ER stress plays a crucial role in pulmonary fibrosis, indicating a positive feedback in lung fibroblasts. Targeting eHSP90α and alleviating fibroblast ER stress may be promising therapeutic approaches for pulmonary fibrosis.
