The non-classical class I human leukocyte antigen (HLA)-G molecule was found to be predominately expressed in the extravillous cytotrophoblasts at the fetal-maternal interface during pregnancy. This molecule is critically important for successful implantation during human pregnancy. The polymorphic insertion-deletion (indel) 14-base pair (bp) site localized at the 3' untranslated region was associated with HLA-G mRNA stability and isoform alternative splicing patterns, and thus may influence HLA-G function during pregnancy.
We performed an association study to evaluate the contribution of 16 killer cell immunoglobulin-like receptor (KIR) genotype polymorphisms and the HLA-C1 and -C2 ligands in the development of colorectal cancer (CRC) in Saudi Arabian patients.
METHODS:
A total of 52 patients with different stages of malignant CRC as well as 70 healthy Saudi controls were enrolled at the King Khalid University Hospital.
The role of IL-1β in regulating the expression and secretion of cytokines and chemokines by human adipocytes was examined. Adipocytes were incubated with human IL-1β for 4 or 24 h. The expression of a panel of 84 cytokine/chemokine genes was probed using PCR arrays. IL-1β stimulated the expression of >30 cytokine/chemokine genes on the arrays; 15 showed >100-fold increases in mRNA at 4 or 24 h including CSF3, CXCL1, CXCL2, CXCL12 and IL8. CSF3 exhibited a 10 000-fold increase in mRNA at 4 h. ADIPOQ was among the genes whose expression was inhibited.
