abstract = {The basal-like transcriptional subtype of pancreatic ductal
adenocarcinoma (PDAC) is linked to therapy resistance and
poor prognosis. The cancer stem cell marker aldehyde
dehydrogenase 1A3 (ALDH1A3) is a critical enzyme in
acetaldehyde metabolism, but the interconnection to the
basal-like subtype is poorly understood. Here, we identified
ALDH1A3 as a key gene, which correlates with reduced
survival and increased tumor growth. Functional studies
revealed interaction of ALDH1A3 with genes like FAM3C, MCC,
PMEPA1, and IRS2, forming a network driving PDAC
progression. Chromatin profiling showed that ALDH1A3 affects
acetylation of histone 3, mediating AP-1 activity,
particularly via FOS family members, activating oncogenic
pathways such as MAPK and TNF signaling. RUNX2 emerged as a
therapeutic target within this network, as its knockdown
disrupted MAPK signaling and reduced tumor growth. These
findings emphasize the role of ALDH1A3 in linking nuclear
metabolic-epigenetic programming in basal-like PDAC,
highlighting it as a promising therapeutic target for novel
treatment strategies.},
