Abstract:
Objective To explore the expression of merlin and cyclins and the nucleocytoplasmic shuttling of merlin in abiogenous vestibular schwannoma tissues. Methods Four paraffin imbedding vestibular Schwannoma samples were included in the study.The cyclins and merlin were analyzed by immunofluorescence at the same time,and the expression and location were synchronously observed with confocal laser microscopy(CLM) in a single schwannoma cell. Results Cyclins and merlin were perspicuously and synchronously presented in a single cell in vestibular schwannoma tissues.In early G1 phase of the tumor cell,merlin was mainly stained in the nucleus,followed by perinucleus and cytoplasm.In G1/S phase,merlin was concentrated in the perinucleus,less in the nucleus and cytoplasm.Merlin staining showed uniform distribution in the nucleus in G2/M phase,while was absent from the nucleus and concentrated in the perinucleus in late G2/M phase. Conclusion The expression of merlin and various kinds of cyclins can be synchronously presented in abiogenous vestibular schwannoma cells with immunofluorescence and CLM.Merlin is shuttling among the nucleus,cytoplasm and perinucleus along with the progression of cell cycle.
