Periostin promotes invasiveness and resistance of pancreatic cancer cells to hypoxia-induced cell death: role of the beta4 integrin and the PI3k pathway.
Recent data identify 3-phosphoinositide-dependent protein kinase 1 as a key tumour-initiating event downstream KRAS interaction with PI3K in pancreatic cancer.
Collectively, TMEM158 was upregulated in PC and promoted PC cell proliferation, migration, and invasion through the activation of TGFβ1 and PI3K/AKT signaling pathways, highlighting its potential as a tumor promoter and a therapeutic target for PC.
Targeting of pathways downstream of RAS represents a promising therapeutic strategy for pancreatic cancer, the fourth leading cause of cancer-related death in the USA, since activation of the Raf-MEK-ERK and PI3K-AKT pathways is found frequently in this disease and is associated with poor prognosis.
Our data support a dosage-dependent role for PTEN, and the resulting dysregulation of the PI3K/AKT signaling axis, in both PDAC initiation and progression, and shed additional light on the signaling mechanisms that lead to the development of ADM and subsequent mPanIN and pancreatic cancer.
In sum, we show that Ad-mda7 is able to induce growth inhibition and apoptosis in pancreatic cancer cells via inhibition of the Wnt/PI3K pathways and identify a novel bystander mechanism of MDA-7 killing in pancreatic cancer that functions via IL-20 receptors.
Activation of phosphoinositide-3 kinase (PI3K)-AKT-mammalian target of rapamycin (mTOR) pathway plays an important role in pancreatic cancer progression and chemo-resistance.
According to the results of further mechanistic investigations, Girdin may regulate cell processes through the phosphatidylinositol‑3‑kinase/protein kinase B (PI3K/Akt) signalling pathway to exert additive effects on pancreatic cancer.
Taken together, our results suggest that activation of PPARgamma may represent a novel approach for the treatment of pancreatic cancer by increasing PTEN levels and inhibiting PI3K activity.
Mechanistically, the knockdown of ABHD11-AS1 decreased phospho(p) AKT and phospho(p) PI3K expression, but did not affect the AKT and PI3K expression in PC cells CONCLUSIONS: This study suggested that ABHD11-AS1 may potentially function as a valuable prognostic biomarker and a therapeutic target for PC patients.
