SQSTM1 and cancer: Other proteins regulated by β-escin in the mesothelial cells (Supplementary Tables S1 and S2), and similarly regulated by β-escin and cardiac glycosides in cancer cells, are SQSMT1/p62 and the ratio of LC3A/B, the proteins shown in Supplemental Figure S4 to be involved in the autophagic degradation of protein aggregates.
