abstract = {Vestibular schwannoma (VS) are benign cranial nerve sheath
tumors of the vestibulocochlear nerve. Their incidence is
mostly sporadic, but they can also be associated with
NF2-related schwannomatosis (NF2), a hereditary tumor
syndrome. Metastasis associated in colon cancer 1 (MACC1) is
known to contribute to angiogenesis, cell growth,
invasiveness, cell motility and metastasis of solid
malignant cancers. In addition, MACC1 may be associated with
nonsyndromic hearing impairment. Therefore, we evaluated
whether MACC1 may be involved in the pathogenesis of VS.
Sporadic VS, recurrent sporadic VS, NF2-associated VS,
recurrent NF2-associated VS and healthy vestibular nerves
were analyzed for MACC1 mRNA and protein expression by
quantitative polymerase chain reaction and
immunohistochemistry. MACC1 expression levels were
correlated with the patients' clinical course and symptoms.
MACC1 mRNA expression was significantly higher in sporadic
VS compared to NF2-associated VS (p < 0.001). The latter
expressed similar MACC1 concentrations as healthy vestibular
nerves. Recurrent tumors resembled the MACC1 expression of
the primary tumors. MACC1 mRNA expression was significantly
correlated with deafness in sporadic VS patients (p =
0.034). Therefore, MACC1 might be a new molecular marker
involved in VS pathogenesis.},
