The late gestation lung 1 (LGL1) gene product, lgl1, is crucial for fetal rat lung airway branching morphogenesis. Inhibiting LGL1 with antisense oligodeoxynucleotides impaired lung development, confirming its vital role.

Area of Science:

  • Developmental Biology
  • Gene Expression
  • Molecular Biology

Background:

  • The late gestation lung 1 (LGL1) gene is a novel glucocorticoid-inducible gene identified in fetal lung mesenchyme.
  • Previous studies described the cloning of LGL1, but its functional role in lung development was not fully elucidated.

Purpose of the Study:

  • To investigate the role of the LGL1 gene product (lgl1) in fetal rat lung airway branching morphogenesis.
  • To determine the temporal and spatial localization of LGL1 mRNA and lgl1 protein during fetal lung development.
  • To correct the previously published LGL1 sequence.

Main Methods:

  • Reverse transcriptase-polymerase chain reaction (RT-PCR) and in situ hybridization were used to detect LGL1 mRNA.
  • Western analysis and immunohistochemistry were employed to detect lgl1 protein.

  • Antisense oligodeoxynucleotides were used to inhibit LGL1 function in fetal rat lung explant cultures.
  • Main Results:

    • LGL1 mRNA and lgl1 protein were detected throughout fetal lung development, with increasing expression as gestation progressed.
    • LGL1 expression was localized to mesenchymal and smooth muscle cells.
    • Antisense inhibition of LGL1 dose-dependently inhibited airway branching morphogenesis and reduced lgl1 protein and LGL1 mRNA levels.

    Conclusions:

    • The lgl1 protein plays a significant role in fetal rat lung airway branching morphogenesis.
    • LGL1 expression is temporally and spatially regulated during lung development.
    • Targeting LGL1 offers a potential avenue for understanding and potentially intervening in lung development processes.
