BLOC1S4 and ovarian cancer: To determine whether pGSN is associated with the dense granule formation, we interrogated the ovarian cancer TCGA public dataset (http://gepia.cancer-pku.cn/index.html) accessed on 12 February 2022 to assess the correlation (Spearman coefficient) between pGSN and genes (BLOC1S1, BLOC1S2, BLOC1S3, BLOC1S4, BLOC1S5, BLOC1S6, DTNBP1, RAB32, RAB38, SNAPIN, VPS11, VPS16, VPS18, VPS33A, VPS33B, VPS39, VPS41) associated with dense granule formation.
