However, after stratified analysis, the genotype AA of AKTrs6973569 carried a higher risk of osteosarcoma metastasis (OR:2.94, 95%CL:1.00-8.59); the difference of rs7646409 genotype distributions between the case and control groups was statistically significant (P = 0.032).
Finally, we detected a time-dependent decrease in VEGF expression and considerably reduced phosphoinositide 3-kinase (PI3K) and protein kinase B (AKT) activation in osteosarcoma cells treated by Eag1 shRNA.
The PPI network revealed eight hub genes: Ubiquitin‑60S ribosomal protein L40, Ras‑related C3 botulinum toxin substrate, mitogen‑activated protein kinase 1, epidermal growth factor receptor, cystic fibrosis transmembrane conductance regulator, PI3K regulatory subunit 1, AKT1, and actin‑related protein 2/3 complex subunit 1A, which may be the key target genes of miR‑542‑3p in OS.
In conclusion, the study indicated that FER1L4 acted as a tumor suppressor in osteosarcoma via activating PI3K/AKT pathway may be a new prognostic biomarker and potential therapeutic target for osteosarcoma intervention.
K-Ras<sup>G12V/Y40C</sup>-PI3K/AKT pathway regulates H1.4<sup>S35ph</sup> through PKA to promote the occurrence and development of osteosarcoma cancer.
MiR-524 induces the proliferation of osteosarcoma cells through activation of the PI3K/AKT pathway via inhibition of the target gene PTEN, which provides a theoretical basis for selecting a new therapeutic target for osteosarcoma.
We found that hBMSC-MVs promoted U2OS cell proliferation and migration under hypoxia in vitro, and that was partially associated with the PI3K/AKT and HIF-1α pathways.
Western blot analysis was performed to detect the expression levels of phosphatidylinositol 3‑kinase (PI3K), phospho (p)‑PI3K, RAC‑alpha serine/threonine‑protein kinase (AKT), p‑AKT and NF‑κB inhibitor α (IκBα) in osteosarcoma cells transfected with H19 siRNA.
In addition, we further found that those effects on osteosarcoma by NRSN2 are associated with the dysregulated PI3K/AKT/mTOR signaling and Wnt/β-catenin signaling.
Moreover, <i>UCA1</i> increases CREB1 expression by functioning as a ceRNA against miR-582, thus promoting the EMT process via CREB1-mediated PI3K/AKT/mTOR pathway and finally leading to osteosarcoma metastasis.
Lowly expressed microRNA-520d-3p was observed in osteosarcoma; overexpression of microRNA-520d-3p can target Akt1 thus inhibiting proliferation of osteosarcoma cells.
Overexpression of hsa_circ_0007534 predicts unfavorable prognosis for osteosarcoma and regulates cell growth and apoptosis by affecting AKT/GSK-3β signaling pathway.
We recently demonstrated that heat shock protein 90 (HSP90) is involved in the regulation of runt-related transcription factor 2 via the AKT/GSK-3β/β-catenin signaling pathway in OS.
