Summary of the cytokine profiles by competitive reverse transcriptase-polymerase chain reaction
| Normal oesophagus | Oesophagitis | Barrett's oesophagus | Gastric antrum | Duodenum | |
|---|---|---|---|---|---|
| Level of cytokines are graded semiquantitatively using squamous oesophagus as baseline (+), where ++ and +/− signify increased or reduced expression, respectively. | |||||
| Gastric antrum and duodenal epithelia are control tissues from the same patients. | |||||
| IFN-γ, interferon γ; IL, interleukin. | |||||
| IL-1β | + | ++ | + | +/− | +/− |
