Vestibular schwannomas (VSs), also known as acoustic neuromas, are intracranial tumors that typically arise from the vestibular nerves and cause hearing loss and tinnitus. We aim to understand mechanisms of this hearing loss, which will inform the development of future therapies to prevent and treat this hearing loss. By focusing on VS-secreted molecules, we discovered that TNFa, a pro-inflammatory molecule, is an ototoxic and FGF2 an otoprotective molecule secreted by VSs (Dilwali, Landegger et al, 2015). We further revealed that VS cells secrete extracellular vesicles that can damage cochlear cells (Soares et al, 2016). We discovered that anti-inflammatory medications that signal through NFkB (Dilwali, Briet et al, 2015) or COX-2 (Dilwali, Kao et al, 2015) reduce VS cell proliferation in vitro, in line with our finding that aspirin intake correlates with reduced growth of VS in vivo (Kandathil et al, 2014). Taken together, our findings have motivated the ongoing prospective, randomized, placebo-controlled phase II clinical trial of aspirin for vestibular schwannoma.
