This study aimed to explore the effect of miR-99b-5p (miR-99b) on invasion and migration in cervical cancer through the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/mechanistic target of rapamycin (mTOR) signaling pathway.
Suppression of Akt with a specific inhibitor impaired the invasion ability of CD47-overexpressing cells, indicating that stimulation of the PI3K/Akt pathway served as the downstream regulator of CD47-triggered invasion.
Taken together, these results suggest that insulin induced migration and invasion in HPNE and HPNE-mut-KRAS through PI3K/AKT and ERK1/2 activation, with MMP-2 gelatinolytic activity playing a vital role in this process.
Furthermore, the PI3K/Akt pathway inhibitor MK-2206 reversed the resistance to paclitaxel and inhibited the migration and invasion of breast cancer cells.
Transcription factor SOX2 is highly expressed in invasive gliomas and maps to chromosome region 3q26 together with the genes for PI3K/AKT signaling activator PIK3CA and effector molecules of mitochondria fusion and cell invasion, MFN1 and OPA1.
Galangin induced antitumor effects in human kidney tumor cells mediated via mitochondrial mediated apoptosis, inhibition of cell migration and invasion and targeting PI3K/ AKT/mTOR signalling pathway.
CONCLUSIONS Our results suggest that C₁₈H₁₇NO₆ can inhibit human MNNG osteosarcoma cell invasion and migration via the PI3K/AKT signaling pathway both in vivo and in vitro.
Up-regulation of miR-155 can promote the proliferation of NPC cells and inhibit cell apoptosis by targeting the PTEN-PI3K/AKT pathway, thereby participating in the development and invasion of NPC, indicating that it might be a potential novel target for treating NPC.
Mahanine induces apoptosis, cell cycle arrest, inhibition of cell migration, invasion and PI3K/AKT/mTOR signalling pathway in glioma cells and inhibits tumor growth in vivo.
Insulin-like growth factors 1 (IGF-1) and PI3k/Akt was assayed for elaborating antagonistic mechanism of Metuzumab in migration and invasion of esophageal cancer cells.
The expression of CyclinD1, apoptosis related proteins (p53, Bcl-2, Bax, pro-/Cleaved-Caspase-3), migration and invasion related proteins (MMP-9 and vimentin), and phosphatidylinositol 3'-kinase (PI3K)/protein kinase B (AKT) related proteins (p/t-PI3K, p/t-AKT) were examined by western blot.
Knockdown of HOXC10 could inhibit the GBM U87 cells proliferation, migration and invasion, as well as decreased expression levels of key proteins in PI3K/AKT signalling pathway.
Specifically, we explore the roles that downstream activation of the mitogen activated protein kinase/extracellular signal-related kinase (MAPK/ERK), protein kinase C, p38 MAPK, and phosphatidylinositol 3-kinase/Akt (PI3K/Akt) pathways play in mediating colon cancer cell proliferation, survival, migration and invasion.
It showed no significant effects on Akt expression, while PI3K activator treatment reduced the inhibitory effects of MALAT1 knockdown on the proliferation, migration and invasion of tongue cancer cells.
