Stress granules (SGs) are cytoplasmic mRNA-protein condensates formed in response to cellular stressors, such as oxidative stress, ultraviolet radiation, and viral infection (1). The Ras-GTPase-activating protein-binding proteins (G3BPs), consisting of G3BP1 and G3BP2, are key nucleating factors essential for SG formation. They function to protect RNAs from harmful conditions. G3BP2 is mainly distributed in the cytoplasm and participates in the formation of stress granules, cell differentiation, proliferation, and signal transduction. Accumulating evidence has demonstrated that aberrant expression of G3BP2 contributes to cancer initiation and progression, such as high expression of G3BP2 increasing cell stemness, metastasis and chemoresistance in breast cancer.

Proteins were extracted from H69 cells using Laemmli lysis buffer (12.5mMNa2HPO4, 15% glycerol, 3% sodium dodecyl sulfate [SDS]). The proteinconcentration was measured with the DC Protein Assay (BIO-RAD) and 30μgof total proteins were loaded onto 12% SDS- polyacrylamide gels forelectrophoresis and transferred onto polyvinylidene difluoride membranes(Millipore). After 1h of blocking with 5% bovine serum albumin preparedin Phosphate-Buffered Saline (PBS)-0.1% Tween-20 buffer, the blots wereincubated overnight at 4°C with the indicated antibody (dilution 1/1000). After 1h of incubation with a horseradish peroxidase-conjugated secondary antibody (1:5,000, Promega), protein bands were visualized using an enhancedchemiluminescence detection kit (Millipore) and and the Syngene Pxi4imaging system (Ozyme).
