abstract = {Drug resistance is a leading cause for treatment failure in
many cancers, including neuroblastoma, the most common solid
extracranial childhood malignancy. Previous studies from our
lab indicate that histone deacetylase 10 (HDAC10) is
important for the homeostasis of lysosomes, i.e. acidic
vesicular organelles involved in the degradation of various
biomolecules. Here, we show that depleting or inhibiting
HDAC10 results in accumulation of lysosomes in
chemotherapy-resistant neuroblastoma cell lines, as well as
in the intracellular accumulation of the weakly basic
chemotherapeutic doxorubicin within lysosomes. Interference
with HDAC10 does not block doxorubicin efflux from cells via
P-glycoprotein inhibition, but rather via inhibition of
lysosomal exocytosis. In particular, intracellular
doxorubicin does not remain trapped in lysosomes but also
accumulates in the nucleus, where it promotes neuroblastoma
cell death. Our data suggest that lysosomal exocytosis under
doxorubicin treatment is important for cell survival and
that inhibition of HDAC10 further induces DNA double-strand
breaks (DSBs), providing additional mechanisms that
sensitize neuroblastoma cells to doxorubicin. Taken
together, we demonstrate that HDAC10 inhibition in
combination with doxorubicin kills neuroblastoma, but not
non-malignant cells, both by impeding drug efflux and
enhancing DNA damage, providing a novel opportunity to
target chemotherapy resistance.},
