abstract = {Muscle-invasive bladder cancer (MIBC) is associated with
limited response rates to systemic therapy leading to a
significant risk of recurrence and death. A recently
discovered histone methyltransferase KMT9, acts as an
epigenetic regulator of carcinogenesis in different tumor
entities. In this study, we investigated the presence and
association of histological and molecular subtypes and their
impact on the survival of KMT9α in MIBC. We performed an
immunohistochemical (IHC) analysis of KMT9α in 135 MIBC
patients undergoing radical cystectomy. KMT9α was
significantly overexpressed in the nucleus in MIBC compared
to normal urothelium and low-grade urothelial cancer. Using
the HTG transcriptome panel, we assessed mRNA expression
profiles to determine molecular subtypes and identify
differentially expressed genes. Patients with higher nuclear
and nucleolar KMT9α expression showed basal/squamous
urothelial cancer characteristics confirmed by IHC and
differentially upregulated KRT14 expression. We identified a
subset of patients with nucleolar expression of KMT9α,
which was associated with an increased risk of death in uni-
and multivariate analyses (HR 2.28, $95\%CI$ 1.28-4.03, p =
0.005). In conclusion, basal-like MIBC and the squamous
histological subtype are associated with high nuclear KMT9α
expression. The association with poor survival makes it a
potential target for the treatment of bladder cancer.},
