In Vitro

The treatment of MYCN2 (±Dox) and BE(2)-C cells with GC7 for 72 h at various concentrations (0.1 to 100 μM) significantly reduces the number of viable cells in a dose-dependent manner. In MYCN2 cells, 5 μM of GC7 inhibits cell viability by ~40 and ~60 %, respectively, compare to untreated control cells. BE(2)-C cells require 25 μM of GC7 to reduce cell viability by ~50 %. Exposure to 10 and 100 μM GC7 for 72 h clearly decreases the levels of total retinoblastoma (Rb) and phosphorylated Rb as well as of Cdk4 protein, and increases the levels of p21 protein^[1]. Between 0 and 20 μM, GC7 induces little cytotoxicity in HCC cells, while higher concentrations of GC7 (50 to 100 μM) significantly inhibit the viability of all five HCC cell lines tested. Newly synthesized ³H-labeled hypusine of eIF5A1/eIF5A2 is rarely detected after 20 μM GC7 treatment, compare to untreated control. The activity of [³H]-spermidine incorporated into HCC cells is significantly decreased by 20 μM GC7 or higher concentration^[2].

Protocole

Cell Assay^[1]

Cell viability is analyzed with the MTS assay kit in accordance with the manufacturer’s protocols. Briefly, after treatment with GC7 for 72 h at various concentrations (0.1 to 100 μM) in 96-well plates, cells are directly incubated with the MTS dye reagent for 1 h at 37°C in a 5 % CO₂ atmosphere. The absorbance is read at 490 nm using a reader^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
