In addition, targeting either HDAC3 or HDAC6 could also decrease the expression of survivin and increased the conversion of LC3-B-II in mutant p53-expressing SK-BR-3 breast cancer cells, further supporting the role of HDAC3 and HDAC6 in regulating survivin expression in the SAHA treated breast cancer cells regardless to the p53 status (Supplementary Figure 3). Here, HDAC3 is linked to breast cancer.
