RACK1 and central nervous system cancer: In order to further determine the prognostic significance of RACK1 in glioma, Kaplan–Meier survival analysis was performed to evaluate the relationship between RACK1 expression levels and overall survival rates in 92 glioma cases, discovering that patients with high RACK1 expression had a significantly worse prognosis than those with low expression levels (Figure 1E, p = 0.0062, HR = 1.898, 95% CI: 1.225–3.203).
