abstract = {Batten disease is characterized by early-onset blindness,
juvenile dementia and death within the second decade of
life. The most common genetic cause are mutations in CLN3,
encoding a lysosomal protein. Currently, no therapies
targeting disease progression are available, largely because
its molecular mechanisms remain poorly understood. To
understand how CLN3 loss affects cellular signaling, we
generated human CLN3 knock-out cells (CLN3-KO) and performed
RNA-seq analysis. Our multi-dimensional analysis reveals the
transcriptional regulator YAP1 as a key factor in remodeling
the transcriptome in CLN3-KO cells. YAP1-mediated
pro-apoptotic signaling is also increased as a consequence
of CLN3 functional loss in retinal pigment epithelia cells,
and in the hippocampus and thalamus of Cln3Δ7/8 mice, an
established model of Batten disease. Loss of CLN3 leads to
DNA damage, activating the kinase c-Abl which phosphorylates
YAP1, stimulating its pro-apoptotic signaling. This novel
molecular mechanism underlying the loss of CLN3 in mammalian
cells and tissues may pave a way for novel c-Abl-centric
therapeutic strategies to target Batten disease.},
