  • ||||||||||  danusertib (PHA-739358) / Nerviano Medical Sciences, buparlisib (BKM120) / Novartis, Adlai Nortye
    Preclinical, Journal:  ERK-dependent IL-6 positive feedback loop mediates resistance against a combined treatment using danusertib and BKM120 in Burkitt lymphoma cell lines. (Pubmed Central) -  Aug 19, 2020   
    A blockade of ERK signaling with trametinib suppressed the combination treatment-induced ERK activation, reduced IL-6 mRNA expression, and downregulated IL-6R mRNA expression, resulting in an improvement in the antitumor effect. We stepwise treated Namalwa cells with both inhibitors using on-and-off treatment cycles and found that Namalwa cells gained chemoresistance by activating the ERK/IL-6 feedback loop, suggesting that the ERK-dependent IL-6 positive feedback loop can compensate for AKT inactivation and is closely associated with adaptive resistance and relapse.

    Journal:  Phosphatidylinositol 3 Kinase δ Inhibitors: Present and Future. (Pubmed Central) -  Aug 18, 2020   
    Newer drugs in development are attempting to reduce toxicity with novel schedules and/or combinations. This article reviews the clinical data on efficacy and toxicity across the class and discusses ongoing efforts to understand and mitigate the likely on-target autoimmune toxicity.
  • ||||||||||  Journal:  Resistance Mechanisms to Targeted Agents in Chronic Lymphocytic Leukemia. (Pubmed Central) -  Aug 18, 2020   
    Determining which patients will develop resistance, why resistance occurs, how to overcome resistance, and when to test for resistance are all subjects of ongoing research. In this review, we describe the current data relative to the development of resistance to targeted therapies in CLL.
  • ||||||||||  AG1478 / IDT Australia
    Preclinical, Journal:  In Vitro Evaluation of the Neuroprotective Effect of Panax notoginseng Saponins by Activating the EGFR/PI3K/AKT Pathway. (Pubmed Central) -  Aug 18, 2020   
    Different groups of OGD SH-SY5Y cells were treated with varying doses of PNS, PNS + AG1478 (a specific inhibitor of EGFR), or AG1478 for 16 hours...Additionally, ratios of p-EGFR, p-PI3K, and p-AKT to EGFR, PI3K, and AKT proteins expression, respectively, all increased significantly. These findings indicate that PNS enhanced neuroprotective effects by activating the EGFR/PI3K/AKT pathway and elevating phosphorylation levels in OGD SH-SY5Y cells.
  • ||||||||||  Review, Journal:  Targeting Mutant KRAS in Pancreatic Cancer: Futile or Promising? (Pubmed Central) -  Aug 17, 2020   
    Currently, several different combination therapies for KRAS cancer are being explored. If they hold the promise they have made in preclinical studies, they might also be suitable treatment options for patients suffering from PDAC.
  • ||||||||||  Journal:  Reduced m6A modification predicts malignant phenotypes and augmented Wnt/PI3K-Akt signaling in gastric cancer. (Pubmed Central) -  Aug 15, 2020   
    In short, our results suggested that the cardioprotective role of SDX was related to the suppression of ER stress in mice MI/R models and TBHP-induced H9C2 cell injury which was through the PI3K/Akt signalling pathway. Our work demonstrated that low-m6A signatures predicted adverse clinicopathological features of GC, while the reduction of RNA m6A methylation activated oncogenic Wnt/PI3K-Akt signaling and promoted malignant phenotypes of GC cells.
  • ||||||||||  Journal:  Vitamin C kills thyroid cancer cells through ROS-dependent inhibition of MAPK/ERK and PI3K/AKT pathways via distinct mechanisms. (Pubmed Central) -  Aug 15, 2020   
    On the other hand, vitamin C exerted its antitumor activity in BRAF mutant thyroid cancer cells by inhibiting the activity of ATP-dependent MAPK/ERK signaling and inducing proteasome degradation of AKT via the ROS-dependent pathway. Our data demonstrate that vitamin C kills thyroid cancer cells by inhibiting MAPK/ERK and PI3K/AKT pathways via a ROS-dependent mechanism and suggest that pharmaceutical concentration of vitamin C has potential clinical use in thyroid cancer therapy.
  • ||||||||||  Journal:  A triple action CDK4/6-PI3K-BET inhibitor with augmented cancer cell cytotoxicity. (Pubmed Central) -  Aug 15, 2020   
    Our data demonstrate that vitamin C kills thyroid cancer cells by inhibiting MAPK/ERK and PI3K/AKT pathways via a ROS-dependent mechanism and suggest that pharmaceutical concentration of vitamin C has potential clinical use in thyroid cancer therapy. No abstract available
  • ||||||||||  Review, Journal:  Novel targeted therapies for metastatic breast cancer. (Pubmed Central) -  Aug 15, 2020   
    As researchers and clinicians attempt to tackle this challenge, there has been extensive research and many trials studying treatment options for BC patients with metastatic disease, with numerous new therapies being discovered as a result. We review the most pertinent novel agents to enter the scope of BC treatment, including CDK4/6 inhibitors, PI3K inhibitors, mTOR inhibitors, immunotherapy, PARP inhibitors, and more.
  • ||||||||||  Journal, IO Biomarker:  MicroRNA-448 inhibits the regeneration of spinal cord injury through PI3K/AKT/Bcl-2 axis. (Pubmed Central) -  Aug 14, 2020   
    We review the most pertinent novel agents to enter the scope of BC treatment, including CDK4/6 inhibitors, PI3K inhibitors, mTOR inhibitors, immunotherapy, PARP inhibitors, and more. MicroRNA-448 is upregulated after SCI, which may be involved in the regenerative process of spinal motor nerves by regulating PI3K/AKT/Bcl-2 axis.
  • ||||||||||  Journal:  MiR-21 promotes fracture healing by activating the PI3K/Akt signaling pathway. (Pubmed Central) -  Aug 14, 2020   
    MicroRNA-448 is upregulated after SCI, which may be involved in the regenerative process of spinal motor nerves by regulating PI3K/AKT/Bcl-2 axis. MiR-21 promotes the fracture healing in fractured rats by activating the PI3K/Akt signaling pathway.
  • ||||||||||  Review, Journal:  The Role of CDK4/6 Inhibitors in Breast Cancer. (Pubmed Central) -  Aug 14, 2020   
    Additional approved indications, including first- and second-line combination therapy for pre-menopausal women, combination with fulvestrant and use as monotherapy, vary with each agent and are reviewed fully in the subsequent texts...Resistance to CDK4/6 inhibition can occur through multiple mechanisms. Rational combinations with other therapies, such as PI3K inhibitors, HER2-directed therapies and immunotherapy, are being explored.

    Journal:  Nicorandil alleviates apoptosis in diabetic cardiomyopathy through PI3K/Akt pathway. (Pubmed Central) -  Aug 14, 2020   
    Also, PI3K inhibitor (Miltefosine) and mTOR inhibitor (rapamycin) were used to inhibit PI3K/Akt pathway...After inhibition of PI3K/Akt pathway, the protective effect of nicorandil is restrained. These results verified that as a NO donor, nicorandil can also inhibit apoptosis in diabetic cardiomyopathy which is mediated by PI3K/Akt pathway.
  • ||||||||||  Preclinical, Journal:  Acute physical exercise increases APPL1/PI3K signaling in the hypothalamus of lean mice. (Pubmed Central) -  Aug 14, 2020   
    Finally, we found an acute exercise session reduced the food intake five hours after the end of fasting. In conclusion, our results indicate that physical exercise reduces the food intake and increases some proteins related to adiponectin pathway in the hypothalamus of lean mice.
  • ||||||||||  vincristine / Generic mfg.
    Journal:  Suppression of c-Myc using 10058-F4 exerts caspase-3-dependent apoptosis and intensifies the antileukemic effect of vincristine in pre-B acute lymphoblastic leukemia cells. (Pubmed Central) -  Aug 13, 2020   
    Although the inhibition of PI3Kδ using Idelalisib upregulated the messenger RNA expression of autophagy-related genes in 10058-F4-treated cells, treatment with autophagy inhibitor chloroquine decreased viability of the cells, either as a single agent or in combination with Idelalisib and/or 10058-F4; suggesting that the activation of autophagy in pre-B ALL cells could blunt apoptotic events and attenuate anticancer effect of both c-Myc and PI3K inhibitors. Finally, the results of our synergistic experiments delineated that 10058-F4 produced a synergistic effect with vincristine and provided an enhanced therapeutic efficacy in ALL cells, highlighting that c-Myc oncoprotein could be a bona fide target for the treatment of ALL.
