HSPB1 and ovarian serous adenocarcinoma: To determine whether high levels of HSP27 expression is associated with poor prognosis, we correlated the HSP27 mRNA levels with overall survival in 1207 high-grade serous ovarian cancer patients using the Kaplan–Meier plotter (https://kmplot.com) and discovered that high HSP27 expression is associated with poor overall survival in high-grade serous ovarian cancer patients (HR + 1.22 (1.04–1.42), logrank p = 0.014; Figure 5C).
