- |||||||||| Review, Journal: Defining Bronchial Asthma with Phosphoinositide 3-Kinase Delta Activation: Towards Endotype-Driven Management. (Pubmed Central) - Jan 8, 2020
Defining subpopulations of asthma patients with PI3K-δ activation, namely PI3K-δ-driven asthma endotype, may therefore provide us with a novel framework for the treatment of the disease, particularly for corticosteroid-resistant severe form, an important unresolved aspect of the current asthma management. In this review, we specifically summarize the recent advancement of our knowledge on the critical roles of PI3K-δ in the pathogenesis of bronchial asthma.

Journal: A Ras-LSD1 axis activates PI3K signaling through PIK3IP1 suppression. (Pubmed Central) - Jan 6, 2020 Using doxycycline-inducible PIK3IP1, here we confirm that reversing the effect of Ras by inducing expression of PIK3IP1 suppresses Ras-induced anchorage-independent growth, supporting the central role of PIK3IP1 in transformation...We find that Ras activity represses PIK3IP1 expression via the recruitment of lysine-specific demethylase 1 (LSD1) to the PIK3IP1 gene promoter and enhancer, resulting in erasure of active histone marks. These studies demonstrate cross-activation of Ras/Raf/MEK/ERK and PI3K/AKT/mTOR pathways, where Ras decommissions PIK3IP1 gene expression by enhancing LSD1 and its corepressor activities to suppress PIK3IP1 transcription.

In summary, lncRNAs have tremendous potential in cancer diagnosis, assessing cancer patient prognosis and in developing new therapeutic options for patients with resistance to current cancer therapies. Thus, understanding how lncRNAs influence the Akt pathway is essential for the development of novel and effective cancer therapies.

Journal: AFAP1-AS1 induces cisplatin resistance in non-small cell lung cancer through PI3K/AKT pathway. (Pubmed Central) - Jan 5, 2020 Silencing of EZH2 inhibited the activation of PI3K/AKT pathway. In conclusion, AFAP1-AS1 accelerates the proliferative and metastatic abilities of A549/DDP cells, whereas inhibits the apoptosis of A549/DDP cells, by interacting with EZH2 to activate the PI3K/AKT pathway; thus, inducing DDP resistance in NSCLC.

In addition, CTT modulated the expression of proteins via the PI3K/AKT pathway, and the inhibition of PI3K/AKT signalling was due to induction of PTEN expression. Taken together, the results of the present study demonstrated the anticancer effect of CTT on bladder cancer cells, which might be associated with the downregulation of PI3K/AKT/mTOR and NF-κB signalling pathway proteins, and this inhibition was mediated by the induction of PTEN.

PI3K inhibitors such as PI-103, PI-828 and PX-866 may be developed as potential therapeutic agents for effective treatment of oral squamous cell carcinoma (OSCC) patients, associated with activated PI3K/Akt pathway. These findings suggested that AsS could induce apoptosis of liver cancer cells in vitro and in vivo, which was related to PI3K/AKT-mediated mitochondrial pathway and may provide a novel promising therapeutic agent for liver cancer treatment.

These findings suggested that AsS could induce apoptosis of liver cancer cells in vitro and in vivo, which was related to PI3K/AKT-mediated mitochondrial pathway and may provide a novel promising therapeutic agent for liver cancer treatment. This study reports on a novel activating p110δ mutation causing adult-onset hypogammaglobulinemia with lymphopenia without the classical presentation of atypical Activated phosphoinositide 3-kinase δ syndrome (ADPS-1), underlining thus the heterogeneous clinical and immunological presentation of p110δ mutated individuals and offers additional data on the role of p110δ in early and late B cell development in humans.

In addition, increased TEEG concentration enhanced the expression of Class III p-PI3K and reduced the expression of Class I p-PI3K, p-AKT, p-mTOR, and p-P70S6K. These results indicate that TEEG induces autophagy of A549 cells through regulation of the PI3K/AKT/mTOR signaling pathway.

Journal: Arctigenin promotes bone formation involving PI3K/Akt/PPARγ signaling pathway. (Pubmed Central) - Dec 30, 2019 Furthermore, arctigenin prevented OVX-induced osteoporosis in rats by increasing BMD and ALP activity and inhibiting the loss of Ca and P. In contrast, treatment with LY294002, a selective inhibitor of the phosphatidylinositol 3-kinase (PI3K), produced the opposite phenotype. These data suggest that the protective effects of arctigenin on BMSCs and OVX rat models result from the induction of osteogenesis involving the PI3K/Akt/PPAR γ axis.
