Modulating miR-206 and RTK Signaling in Osteosarcoma

Check if the same lab product or an alternative is used in the 5 most similar protocols
miR-206 overexpression or inhibition in primary OS cells was achieved by lentiviral transduction. Pseudoviral particles for miR-206 overexpression and miR-206 knockdown (anti-miR-206) and for transduction of miR-negative control (miRNC) were purchased from Fulengen (Guangzhou, China) and were used following manufacturer's instructions. Cells with positive transduction were selected by puromycin (Solarbio, Beijing, China). PAX3 or MET gene overexpression in primary OS cells was achieved by plasmid transfection using Lip2000 transfection reagent (Solarbio). Plasmids for PAX3 or MET gene overexpression were purchased from Solarbio and were used following the manufacturer's instructions. Cells were assayed 48 hours after transfection. Positive transfection was confirmed by verifying the expression of GFP reporter gene encoded in the plasmids.
Recombinant human HGF protein was purchased from R&D system (Shanghai, China) and was used for cell treatment as described by Husmann, et al.21 (link) with modifications. To evaluate Akt1 or Erk1/2 activation, OS cells were serum-deprived for 6 hours before HGF treatment at 100 ng/mL for 30 min. For cell viability, apoptosis, migration, and invasion assay, cells were pretreated with 100 ng/mL of HGF for 16 hours before assay with the presence of HGF at the same concentration.

The human CRC cell lines used in our study were purchased from the American Type Culture Collection (ATCC, USA). HUVEC and CT26 were purchased from Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences. All these cells were cultured in RPMI-1640 medium with 10% fetal bovine serum (FBS), penicillin (107 U/l), and streptomycin (10 mg/l) and incubated at 37 °C and 5% CO2. Recombinant human HGF protein, recombinant human CCL19/MIP-3 beta protein, recombinant human VEGF 165 protein were purchased from R&D systems. Axitinib (VEGF receptor tyrosine kinase inhibitor) and crizotinib (MET inhibitor) were purchased from Selleckchem (Houston, USA) and used in accordance with manufacturer’s instructions.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
