TI  - Forkhead transcription factor HFH-4 expression is temporally related to
      ciliogenesis.
PG  - 168-76
AB  - Members of the forkhead/winged-helix family of transcription factors are
      expressed in tissue-specific patterns and play critical roles in development and 
      cell differentiation. The expression of forkhead family member hepatocyte nuclear
      factor-3/forkhead homologue 4 (HFH-4) has been localized by RNA-blot analysis and
      in situ hybridization to the proximal airway of the lung (trachea, bronchi, and
      bronchioles) with onset at mouse embryonic day (E) 14.5 and is present in the
      choroid plexus, ependymal cells, oviduct, and testis. We hypothesized that the
      restricted expression of HFH-4 messenger RNA suggests a function common to these 
      tissues and therefore a cell-specific role for HFH-4. Accordingly, an anti-HFH-4 
      antibody was generated and used for cell-specific localization of protein
      expression to begin to identify the functions of HFH-4. We found HFH-4 expression
      in proximal airway ciliated epithelial cells, but not Clara cells or alveolar
      epithelial cells. HFH-4 was also expressed in ciliated epithelial cells of the
      nose and paranasal sinuses, choroid plexus, ependyma, and oviduct. In developing 
      mouse lung, HFH-4 expression was initially detected in airway epithelial cells at
      E15.5, before the appearance of cilia, and at later stages was localized to
      epithelial cells with cilia. In the testis, HFH-4 expression in spermatids was
      coincident with stage-specific generation of flagella. The temporal relationship 
      of HFH-4 expression to the development of cilia and flagella, and the restricted 
      expression in ciliated epithelial cells, suggest that this transcription factor
      has a role in regulation and maintenance of the ciliated cell phenotype in
      epithelial cells.
