For the first time, this study show that ANXA2/TNfnA-D interaction induced gemcitabine resistance via the canonical PI3K/Akt/NF-kappaB signaling pathways in pancreatic cancer cells.
Very few anticancer drugs targeting the PI3K pathway have been approved for clinical use and their efficacy is particularly limited towards certain tumors such as pancreatic cancer.
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 the present study, the effects of (‑)‑epigallocatechin‑3‑gallate (EGCG) on PI3K/Akt/mTOR signaling in pancreatic cancer cells and PTEN knockdown cells were measured, in addition to assessing its therapeutic potential 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.
These results indicated that arsenic trioxide could act anti-tumor function through PI3K-Akt single pathway and identified critical genes might be therapeutic targets for pancreatic cancer.
Additionally, we found that combination of sub-optimal concentrations of inhibitors selective for PDK1 and the class IB PI3K isoform p110γ inhibits pancreatic cancer cell growth and colonies formation more potently than each single treatment.
MiR-142 over-expression weakened ADM resistance in pancreatic cancer cells by targeting DJ-1 to enhance PTEN expression and attenuate PI3K/AKT signaling pathway activity.
Activation of phosphoinositide-3 kinase (PI3K)-AKT-mammalian target of rapamycin (mTOR) pathway plays an important role in pancreatic cancer progression and chemo-resistance.
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.
Our study aimed to investigate the interaction between peroxiredoxin 1 (Prx1) and forkhead box O3 (FOXO3) and to explore the role of PI3K/AKT pathway in the development of pancreatic cancer.
