Journal: Carnosine inhibits glioblastoma growth independent from PI3K/Akt/mTOR signaling. (Pubmed Central) - Feb 20, 2020 Therefore, glioblastoma cells from the lines U87 and T98G were exposed to carnosine, to the mTOR inhibitor rapamycin and to the PI3K inhibitor Ly-294,002...We conclude that carnosine's anti-neoplastic effect is independent from PI3K/Akt/mTOR signaling. As the dipeptide reduced viability in tumor cells that do not respond to PI3K or mTOR inhibitors, it appears to be worth to further investigate the mechanisms by which carnosine exerts its anti-tumor effect and to consider it for therapy, especially as it is a naturally occurring compound that has already been used for the treatment of other diseases without indication of side-effects.
- |||||||||| [VIRTUAL] 'Research Domain Criteria' in context: PI3K/PDK1/PKB signaling pathway, fear, anxiety and cognitive deficits (Station 11) - Feb 20, 2020 - Abstract #EPA2020EPA_656;
Variants in C1R might increase risk via a direct effect of complement activity in the brain or indirectly mediated through encouraging periodontitis and P. gingivalis infection. The present results contribute to the in vivo characterization of the behavioral impact of PKB/Akt signal pathway dysfunction and support the conceptualization of qualitative and quantitative variations of neural circuit disruptions underpinning phenotypic differences that are relevant to several mental disorders.
- |||||||||| Journal: Lupiwighteone induces caspase-dependent and -independent apoptosis on human breast cancer cells via inhibiting PI3K/Akt/mTOR pathway. (Pubmed Central) - Feb 20, 2020
We also showed that treatment with lupiwighteone induced caspase-dependent apoptosis (up-regulation of caspase-3, -7, -8, -9, PARP, and Bax or down-regulation of Bid, Bcl-2), induction of caspase-independent apoptosis (up-regulation of AIF and Endo G on cytosol), and inhibition of the PI3K/Akt/mTOR signaling pathway (down-regulation of PI3K, p-Akt, and p-mTOR) in both MCF-7 and MDA-MB-231 cells. These results suggest that lupiwighteone induces caspase-dependent and -independent apoptosis in both breast cancer cell lines via inhibiting PI3K/Akt/mTOR pathway.

Journal: Deoxyshikonin isolated from Arnebia euchroma inhibits colorectal cancer by down-regulating the PI3K/Akt/mTOR pathway. (Pubmed Central) - Feb 16, 2020 In vivo study, the weight of tumour tissues at deoxyshikonin groups was significantly reduced compared with the control group, and PI3K, p-PI3K, Akt, p-Akt308 and mTOR expression was decreased. Discussion and We can conclude that deoxyshikonin isolated from Arnebia euchroma inhibited CRC through the PI3K/Akt/mTOR pathway.
- |||||||||| Journal: Ginkgolide K supports remyelination via induction of astrocytic IGF/PI3K/Nrf2 axis. (Pubmed Central) - Feb 15, 2020
Further findings suggest that IGF/PI3K, but not BDNF, was induced in the corpus callosum after GK treatment, revealing that Nrf2 activation inhibited caspase-3 and apoptosis in O4+ oligodendrocytes possibly through IGF/PI3K signaling molecules. Since the current immunomodulatory therapies for MS have failed to prevent patients from entering the progressive phase of the disease, thus targeting Nrf2 in astrocytes with GK would be an ideal strategy for myelin protection and regeneration.
- |||||||||| Journal: A high-avidity biosensor reveals plasma membrane PI(3,4)P is predominantly a class I PI3K signaling product. (Pubmed Central) - Feb 14, 2020
We show that despite clear evidence for class II PI3K in PI(3,4)P-driven function, the overwhelming majority of the lipid accumulates through degradation of class I PI3K-produced PIP However, we show that PI(3,4)P is also subject to hydrolysis by the tumor suppressor lipid phosphatase PTEN. Collectively, our results show that PI(3,4)P is potentially an important driver of class I PI3K-driven signaling and provides powerful new tools to begin to resolve the biological functions of this lipid downstream of class I and II PI3K.
