  • ||||||||||  quercetin (LY294002) / Eli Lilly
    Journal:  Trans-10-hydroxy-2-decenoic acid alleviates LPS-induced blood-brain barrier dysfunction by activating the AMPK/PI3K/AKT pathway. (Pubmed Central) -  Apr 23, 2020   
    Compound C (an AMPK inhibitor) and LY294002 (a PI3K inhibitor) markedly reversed the alleviating effect of 10-HDA on the expression of tight junction proteins, indicating that 10-HDA inhibited LPS-induced BBB dysfunction by triggering the activation of the AMPK/PI3K/AKT pathway. Collectively, these data reveal that 10-HDA may be an interesting candidate for clinical evaluation in the treatment of diseases related to BBB damage.

    Journal:  PI3K inhibition highlights new molecular interactions involved in the skeletogenesis of Paracentrotus lividus embryos. (Pubmed Central) -  Apr 22, 2020   
    The effects of LY294002 (LY), a PI3K-specific inhibitor, were evaluated at morphological and molecular levels...Based on the present results and in silico analyses, we propose an "interactomic" model simulating PI3K connections in P. lividus embryos. Our findings define a novel regulatory step in the embryonic skeletogenesis, and provide valuable molecular data for further studies on the role of PI3K signaling in invertebrate biomineralization.

    Preclinical, Journal:  Effects of Hydroxysafflor Yellow A on the PI3K/AKT Pathway and Apoptosis of Pancreatic β-Cells in Type 2 Diabetes Mellitus Rats. (Pubmed Central) -  Apr 21, 2020   
    The T2DM rats were treated with HSYA (120mg/kg) or metformin (90mg/kg) for eight weeks...Moreover, HSYA-treatment increased the levels of glycogen synthase and hepatic glycogen and improved lipid metabolism by reducing the triglyceride, total and low-density lipoprotein cholesterol levels, even though it did not change the rats' body weights. The results of this study suggested that HSYA could promote PI3K/Akt activation and inhibit the apoptosis of pancreatic β-cells directly or indirectly, which might be the underlying mechanisms in HSYA to improve insulin resistance and regulate glycolipid metabolism in T2DM rats.
  • ||||||||||  Journal:  Ferulic Acid Ameliorates Lipopolysaccharide-Induced Barrier Dysfunction via MicroRNA-200c-3p-Mediated Activation of PI3K/AKT Pathway in Caco-2 Cells. (Pubmed Central) -  Apr 21, 2020   
    However, pretreatment of FA inhibited expression of PTEN protein and promoted activation of PI3K/AKT signaling pathway in the LPS-treated Caco-2 cells, and this regulatory effect of FA on the PTEN/PI3K/AKT signaling pathway was strengthened or weakened by miR-200c-3p overexpression or suppression, respectively. Our findings suggested that in Caco-2 cells, FA promotes activation of PI3K/AKT pathway by miR-200c-3p-mediated suppression of the negative mediator PTEN, which, in turn, maintains TJ function and thus ameliorates LPS-induced intestinal epithelial barrier dysfunction.
  • ||||||||||  Review, Journal:  SOX2 protein biochemistry in stemness, reprogramming, and cancer: the PI3K/AKT/SOX2 axis and beyond. (Pubmed Central) -  Apr 19, 2020   
    One recurring regulatory principle though is the canonical PI3K/AKT signaling axis to which SOX2 relates in various entangled, albeit not exclusive ways. Here we provide a comprehensive review of the current knowledge on SOX2 protein modifications, their proposed relationship to the PI3K/AKT pathway, and regulatory influence on SOX2 with regards to stemness, reprogramming, and cancer.

    Review, Journal:  Role and Therapeutic Targeting of the PI3K/Akt/mTOR Signaling Pathway in Skin Cancer: A Review of Current Status and Future Trends on Natural and Synthetic Agents Therapy. (Pubmed Central) -  Apr 17, 2020   
    The mammalian or mechanistic target of rapamycin (mTOR) and associated phosphatidyl-inositiol 3-kinase (PI3K)/protein kinase B (Akt) pathways regulate cell growth, differentiation, migration, and survival, as well as angiogenesis and metabolism...Recently, the enhanced understanding of the molecular and genetic basis of skin dysfunction in patients with skin cancers has provided a strong basis for the development of novel therapeutic strategies for these obdurate groups of skin cancers. This review summarizes recent advances in the roles of PI3K/Akt/mTOR and their targets in the development and progression of a broad spectrum of cutaneous cancers and discusses the current progress in preclinical and clinical studies for the development of PI3K/Akt/mTOR targeted therapies with nutraceuticals and synthetic small molecule inhibitors.

    Biomarker, Journal, PARP Biomarker:  Dysfunction of poly(ADP-ribose) glycohydrolase induces a synthetic lethal effect in dual specificity phosphatase 22-deficient lung cancer cells. (Pubmed Central) -  Apr 16, 2020   
    PARG dysfunction sensitizes certain cancer cells to alkylating agents and cisplatin by perturbing the DNA damage response...Consistently, the growth of tumors derived from double knockdown A549 cells was slower compared with those derived from control siRNA transfected cells. Taken together, these results indicate that DUSP22 deficiency exerts a synthetic lethal effect when combined with PARG dysfunction, suggesting that DUSP22 dysfunction could be a useful biomarker for cancer therapy using PARG inhibitors.
  • ||||||||||  Journal:  Activated Phosphoinositide 3 Kinase Delta Syndrome (APDS): A Primary Immunodeficiency Mimicking Lymphoma. (Pubmed Central) -  Apr 16, 2020   
    Malignant or nonmalignant lymphoproliferative disorders together with repeated ear, nose, and throat infections should strongly motivate immunologic investigations. Indeed, we report a 7-year-old patient with a history of persistent abdominal symptoms along with recurrent ear, nose, and throat infections, who presented with intra-abdominal masses highly suggestive of a diagnostic of lymphoma, and who was diagnosed with activated-PI3K-delta syndrome, a recently described primary immunodeficiency prone to lymphoproliferation.

    Journal:  MicroRNA-99b suppresses human cervical cancer cell activity by inhibiting the PI3K/AKT/mTOR signaling pathway. (Pubmed Central) -  Apr 15, 2020   
    This study aimed to explore the effect of miR-99b-5p (miR-99b) on invasion and migration in cervical cancer through the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/mechanistic target of rapamycin (mTOR) signaling pathway...More important, overexpressed miR-99b repressed the PI3K/AKT/mTOR signaling pathway, inhibited cell proliferation, invasion, and migration, blocked cell cycle entry, and promoted apoptosis in cervical cancer. These results indicate that miR-99b attenuates the migration and invasion of human cervical cancer cells through downregulation of the PI3K/AKT/mTOR signaling pathway, which provides a therapeutic approach for cervical cancer treatment.
  • ||||||||||  Journal:  Emerging Role of l-Dopa Decarboxylase in Flaviviridae Virus Infections. (Pubmed Central) -  Apr 14, 2020   
    Consistently, we observed an inverse correlation between DDC mRNA and HCV RNA levels in liver biopsies from chronically infected patients. These data reveal a novel relationship between DDC and Flaviviridae replication cycle and the role of PI3K in this process.
