Docking analysis showed that 4k could reasonably bind to the active sites of Bcl-2, NF-κB/p65, PI3K and AKT. This result suggested that 4k could be used as a new type of NF-κB inhibitor, which provides a scientific basis for further research into the treatment of hepatoma.

Journal: Synergistic cytotoxicity of dual PI3K/mTOR and FLT3 inhibition in FLT3-ITD AML cells. (Pubmed Central) - Jan 14, 2022 Here, we report on the preclinical activity of the combination of the FLT3 inhibitor quizartinib with the dual PI3K/mTOR inhibitor PF-04691502 in FLT3-ITD cells. Briefly, we show that the association of these two molecules displays synergistic cytotoxicity in vitro in FLT3-ITD AML cells, triggering 90% cell death at nanomolar concentrations after 48 h.

Besides, and in the hippocampus of both groups, EA increased the phosphorylation of insulin receptor substrate (IRS), PI3K, Akt, GS3Kβ, and CREB, and increased levels of BDNF and Bcl-2. In conclusion, these data suggest that the neuroprotective effect of EA on rats' hippocampus and memory function is associated with upregulation of Nrf2 and Bcl-2, suppression of NF-κB, and activation of CREB and IRS/PI3K/Akt/ GS3Kβ axis.

Journal: Connexin 43 confers chemoresistance through activating PI3K. (Pubmed Central) - Jan 14, 2022 These two different treatments synergistically inactivate PI3K and sensitize glioblastoma cells to temozolomide in vitro and in vivo. Our study has revealed novel mechanistic insights into Cx43/PI3K-mediated temozolomide resistance in glioblastoma and demonstrated that targeting Cx43 and PIK3CB/p110β together is an effective therapeutic approach for overcoming chemoresistance.

This pathway is activated on stiffer substrates, is amplified by VEGF-A stimulation, and correlates with enhanced endothelial cell (EC) proliferation, contraction, pro-angiogenic secretion, and capillary-like tube formation. In the settings of advanced age-related macular degeneration, characterized by EC and retinal pigment epithelial (RPE)-mediated angiogenesis, these data implicate substrate stiffness as a novel causative mechanism and Akt/mTOR inhibition as a novel therapeutic pathway.

740Y-P, a PI3K activator, reversed the effects of TRAM2 silencing on glioma cell proliferation, invasion, migration and EMT process. Taken together, these findings establish that TRAM2/PI3K/AKT/mTOR signaling drives malignancy properties of glioma and indicate that TRAM2 may act as a potential therapeutic target for glioma.

(Pubmed Central) - Jan 13, 2022 Furthermore, we show that BEZ235 and copanlisib cooperate with nilotinib and ponatinib in suppressing proliferation and survival of osteoblasts and endothelial cells...Together, targeting osteoblastic niche cells through PI3K inhibition may be a new effective approach to overcome niche-induced TKI resistance in CML. Whether this approach can be translated into clinical application and can counteract drug resistance of LSC in patients with CML remains to be determined in clinical trials.

Journal, IO biomarker: DP from Euphorbia fischeriana S. mediated apoptosis in leukemia cells via the PI3k/Akt signaling pathways. (Pubmed Central) - Jan 12, 2022 Whether this approach can be translated into clinical application and can counteract drug resistance of LSC in patients with CML remains to be determined in clinical trials. The in vivo and in vitro experimental results indicated that DP might inhibit the proliferation and induce the apoptosis of leukemia cells, which might be a result of suppressing the PI3k/Akt signaling pathways.

Our data support the therapeutic use of RGS + αPD1 + αCTLA4 in RAS/RAF/PI3K pathway-activated melanomas and point to the need for clinical trials of RGS + ICB for melanoma patients who do not respond to ICB alone.

(Pubmed Central) - Jan 12, 2022 LEV and LY294002 (a PI3K pathway inhibitor) were then administered...Besides, the morphology of testicular tissue in the GTW + LEV and LY + LEV groups was superior to that in the GTW group. We can to the conclusion that LEV may operate via the PI3K/AKT signalling pathway, with increases in PI3K, p-AKT, and BCL-2 protein and mRNA expression, so that the percentages of GC-1 spg cells apoptosis decrease, and the sperm count and motility improve.
