abstract = {Gastrointestinal stromal tumors (GISTs) frequently show KIT
mutations, accompanied by overexpression and aberrant
localization of mutant KIT (MT-KIT). As previously
established by multiple studies, including ours, we
confirmed that MT-KIT initiates downstream signaling in the
Golgi complex. Basic leucine zipper nuclear factor 1 (BLZF1)
was identified as a novel MT-KIT-binding partner that
tethers MT-KIT to the Golgi complex. Sustained activation of
activated transcription factor 6 (ATF6), which belongs to
the unfolded protein response (UPR) family, alleviates
endoplasmic reticulum (ER) stress by upregulating chaperone
expression, including heat shock protein 90 (HSP90), which
assists in MT-KIT folding. BLZF1 knockdown and ATF6
inhibition suppressed both imatinib-sensitive and -resistant
GIST in vitro. ATF6 inhibitors further showed potent
antitumor effects in GIST xenografts, and the effect was
enhanced with ER stress-inducing drugs. ATF6 activation was
frequently observed in $67\%$ of patients with GIST (n =
42), and was significantly associated with poorer
relapse-free survival (P = 0.033). Overall, GIST bypasses ER
quality control (QC) and ER stress-mediated cell death via
UPR activation and uses the QC-free Golgi to initiate
signaling.},
