NR3C1 and Vestibular schwannoma: Carroll et al [6] studied expression of androgen, progesterone glucocorticoid and estrogen receptor messenger ribonucleic acid levels (mRNA) in 21 cases of vestibular schwannomas by either Northern blot analysis or the polymerase chain reaction (PCR) and demonstrated that glucocorticoid receptor mRNA was expressed in 100% of the cases.
