- |||||||||| Journal: Oncogene PRR14 promotes breast cancer through activation of PI3K signal pathway and inhibition of CHEK2 pathway. (Pubmed Central) - Apr 13, 2021
Collectively, our study is the first to document the oncogenetic role of PRR14 in breast cancer, which protects cells from apoptosis and stimulates proliferation by activating the PI3-kinase/Akt/mTOR pathway and inhibiting the CHEK2 pathway. Both of these pathways are of great influence in breast cancer and PRR14 appears to be their novel interacting node, which renders patients more resistance to chemotherapy and provides a potential therapeutic target in breast cancer.

Journal, PD(L)-1 Biomarker, IO biomarker: Circadian rhythm and Period2 regulate the chemotherapy effect and multidrug resistance of ovarian cancer through PI3K signaling pathway. (Pubmed Central) - Apr 13, 2021 Methylation of CpG islands in the promoter of Per2 could result in its decreased expression in SKOV3/DDP(Cisplatin) cells. Dysrhythmia of the circadian clock: (i) had a negative effect on the chemotherapy effect against ovarian cancer; (ii) affected expression of immune factors and the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) signaling pathway. The Per2 gene can affect the drug resistance of ovarian cancer by inhibiting the PI3K/Akt signaling pathway and then acting on its downstream drug-resistance factors, thereby providing a new target for ovarian-cancer treatment.

Journal: NHL Progression Risk Cut with Copanlisib-Rituximab Combo. (Pubmed Central) - Apr 13, 2021 According to results from the phase III CHRONOS-3 trial, patients with relapsed indolent non-Hodgkin lymphoma may benefit significantly from the addition of copanlisib, a pan-PI3K inhibitor, to standard rituximab. The combination was safe and nearly halved the risk of disease progression or death, compared with placebo and rituximab.

Journal: Fisetin inhibits inflammation and induces autophagy by mediating PI3K/AKT/mTOR signaling in LPS-induced RAW264.7 cells. (Pubmed Central) - Apr 13, 2021 Western blot analysis and immunofluorescence assay showed that fisetin decreased microtubule-associated protein 1 light-chain 3B (LC3B) and lysosome-associated membrane protein 1 (LAMP1) expression in LPS-treated cells, while the autophagy inhibitor chloroquine (CQ) could partially reverse this effect...Fisetin diminished the expression and secretion of inflammatory cytokines and facilitated autophagosome-lysosome fusion and degradation in LPS-treated RAW264.7 cells via inhibition of the PI3K/AKT/mTOR signaling pathway. Overall, the results of this study provide new clues for the anti-inflammatory mechanism of fisetin and explain the crosstalk between autophagy and inflammation to some extent.
- |||||||||| Journal: SOX4 and SMARCA4 cooperatively regulate PI3k signaling through transcriptional activation of TGFBR2. (Pubmed Central) - Apr 11, 2021
We further report that SOX4 and the SWI/SNF ATPase SMARCA4, which are uniformly overexpressed in basal-like tumors, form a previously unreported complex that is required to maintain an open chromatin conformation at the TGFBR2 regulatory regions in order to mediate TGFBR2 expression and PI3K signaling. Collectively, our findings delineate the mechanism by which SOX4 and SMARCA4 cooperatively regulate PI3K/Akt signaling and suggest that this complex may play an essential role in TNBC genesis and/or progression.

Notably, FAM134B is required for protein secretion in chondrocytes, and cartilage growth and bone mineralization in medaka fish. This study identifies a new signaling pathway that allows ER-phagy to respond to both metabolic and developmental cues.

Journal, BRCA Biomarker, PARP Biomarker: ClC-3/SGK1 regulatory axis enhances the olaparib-induced antitumor effect in human stomach adenocarcinoma. (Pubmed Central) - Apr 10, 2021 Altogether, our findings illustrate that olaparib exerts antitumor effect in human STAD, and ClC-3/SGK1 regulatory axis enhances the olaparib-induced antitumor effect. Up-regulation of the ClC-3/SGK1 axis may provide promising therapeutic potential for the clinical application of olaparib in STAD treatment.

Journal: LPAR5 Promotes Thyroid Carcinoma Cells Proliferation and Migration by Activating Class IA PI3K Catalytic Subunit p110β. (Pubmed Central) - Apr 10, 2021 We also found that LPAR5-specific antagonist TC LPA5 4, PI3K inhibitor wortmannin, or mTOR inhibitor rapamycin pretreatment abrogated phosphorylation of Akt and p70S6K1 stimulated by LPA in CGTH-W3 and TPC-1 cells...Overall, we provide new insights that the downregulation of LPAR5 decreased the proliferation and migration phenotype via the PI3K/Akt pathway. Inhibition of LPAR5 or PI3K/Akt signal may be the novel therapeutic strategy for treating thyroid cancer.
- |||||||||| Journal: NLRC3 inhibits PDGF-induced PASMCs proliferation via PI3K-mTOR pathway. (Pubmed Central) - Apr 7, 2021
Our data suggest that PDGF can induce abnormal proliferation of PASMCs, and NLRC3 suppresses activation of the PI3K-mTOR signaling thus inhibits PASMCs proliferation. These findings unveiled the effect of NLRC3 as an inhibitor of the PI3K-mTOR pathway mediating protection against PASMCs proliferation.
