Effect of on , and mRNA expression levels in human gastric mucosa.

infects ~50% of the world population, causing chronic gastritis and other forms of cellular damage. The present study assessed the influence of on the mRNA expression levels of nuclear factor-κB1 (), and tumor necrosis factor-α () in human gastric mucosa in a southern Brazilian population. Human gastric tissue was collected by upper endoscopy and diagnosis was performed using a rapid urease test and histological analysis.
