Summary

To look at the effect of Protein kinase A (PKA) on the IL-8 production by airway smooth muscle cells (ASMC's) induced by cigarette smoke extract (CSE), 8-pcpt-2'-o-me-camp (8-pcpt) and 6-Benz-cAMP (6-Benz) are used to inhibited and activate PKA respectively. To illustrate the influence of A kinase Anchoring Proteins (AKAP's) an all round inhibitor of PKA (subunit RII) binding to AKAP's HT31 is used. An inactive peptide HT31P is used as an control.

The purpose of the described method is to stimulate the cells with the substances to prepare for future experiments (e.g. ELISA, Western blot)

Materials & Methods

Materials

Method

  • Remove medium form 24-wells plate with ASMC's grown ON in DMEM (S0)
  • Rinse twice with warm PBS and remove buffer
  • Add 200 μL DMEM (S0) with either HT31 or HT31P (see schedule below)
  • Add 200 μL DMEM S0) to CTR
  • Add 200 μL 8-pctp or 6-benz according to schedule below
  • Wait 25 min.
    • Prepare 25 mL DMEM S0) with 100% CSE
    • Dilute 100% CSE to 45% CSE
  • Add 200 μL 45% CSE to wells according to schedule below
  • Incubate 24 h.
