GABARAPL1 and breast cancer: Pearson correlation analysis revealed that GABARAP or GABARAPL2 expression was not correlated with methylation status (r = −0.45, p = 0.12 and r = 0.36, p = 0.25 Fig. 2d), while GABARAPL1 expression was indeed correlated with the methylation status of the gene (r = −0.58, p = 0.03 suggesting that methylation of the GABARAPL1 promoter may explain the downregulation of GABARAPL1 expression in BC (Fig. 2d).
