Hypothesis

The somatostatinergic system has a protective effect on hair cell loss in the cochlea.

Conclusion

Somatostatin receptors are specifically expressed in hair cells and supporting cells of the mouse cochlea, and the absence of SST1 alters the expression of SST2.

Supporting Evidence

  • The study demonstrated that SST1 and SST2 receptors are expressed in outer and inner hair cells.
  • Immunohistochemistry confirmed the presence of SST1 and SST2 in cochlear tissues.
  • Absence of SST1 led to altered expression patterns of SST2 in supporting cells.

Takeaway

This study found that certain receptors in the ear help protect hearing cells, and if one type of receptor is missing, another type changes how it works.

Methodology

Real-time PCR and immunohistochemistry were used to analyze the expression of somatostatin receptors in cochlear tissues from wild-type and knockout mice.

Limitations

The study primarily focused on mouse models, which may not fully represent human physiology.

Participant Demographics

Wild-type and knockout mice of both sexes were used.
