Chronic neutrophilic inflammation is a manifestation of a variety of lung diseases including cystic fibrosis (CF). There is increasing evidence that fragments of extracellular matrix proteins, such as collagen and elastin, play an important role in inflammatory cell recruitment to the lung in animal models of airway inflammation. Unfortunately, the association of these peptides with human disease and the identification of therapeutic targets directed toward these inflammatory pathways have remained elusive.

The CXC receptor-1 (CXCR1) is a coreceptor for interleukin-8 (IL-8) and is expressed on both normal and tumor cells. The function of CXCR1 in prostate cancer was investigated by silencing its expression, using RNA interference. We established stable cell colonies of PC-3 cells, depleted of CXCR1, using lentiviral plasmids (pLK0.1puro) generating small hairpin RNA (shRNA) against CXCR1 mRNA. Stable shRNA transfectants (PLK1-PLK5) that express significantly reduced CXCR1 mRNA (>or=90% down) and protein (>or=43% down) or vector-only transfectants (PC-3V) were characterized.

OBJECTIVE: To explore the mechanisms of Xiaotan Sanjie Decoction (XTSJD), a compound traditional Chinese herbal medicine, in inhibiting the tumor growth and preventing recurrence by testing the protein expressions of interleukin-8 (IL-8) and its receptors chemokine receptor 1 (CXCR1) and chemokine receptor 2 (CXCR2) in gastric tumor xenografts and gastric tissue adjacent to the tumor in mice. METHODS: Fifty Kunming mice were randomly divided into normal group, normal saline (NS) group, Heat-clearing and Detoxicating Decoction (HCDD) group, tegafur (FT-207) group and XTSJD group.
