The bottle-nosed dolphin (Tursiops truncatus) interleukin-1 receptor antagonist IL-1ra cDNA was cloned from mitogen-stimulated peripheral blood mononuclear cells (PBMC) RNA utilizing the reverse transcription-polymerase chain reaction (RT-PCR). The sequence of this cDNA showed that dolphin IL-1ra clones contained open reading frames encoding 177 amino acids. Comparison of the deduced amino acids showed that dolphin IL-1ra sequence shared 87.6, 77.9, 77.4, 77.4, 76.4, and 75.8% similarity with the bovine, rabbit, equine, human, mouse, and rat IL-1ra sequences, respectively. Recombinant glutathione S-transferase (GST) dolphin IL-1ra produced in Escherichia coli (E. coli) was purified. This protein suppressed the cytostatic activity of dolphin IL-1beta on A375S2 cells, indicating that the dolphin IL-1ra cDNA obtained in the present study encodes biologically active dolphin IL-1ra.

Insulin-regulated aminopeptidase (IRAP, also termed vp165) is known to be localized on the GLUT4-containing vesicles and to be recruited to the plasma membrane after stimulation with insulin. The cytoplasmic region of IRAP contains two dileucine motifs and acidic regions, one of which (amino acid residues 55-82) is reportedly involved in retention of GLUT4-containing vesicles. The region of IRAP fused with glutathione-S-transferase [GST-IRAP(55-82)] was incubated with lysates from 3T3-L1 adipocytes, leading to identification of long-chain, medium-chain, and short-chain acyl-coenzyme A dehydrogenases (ACDs) as the proteins associated with IRAP. The association was nearly abolished by mutation of the dileucine motif of IRAP. Immunoblotting of fractions prepared from sucrose gradient ultracentrifugation and vesicles immunopurified with anti-GLUT4 antibody revealed these ACDs to be localized on GLUT4-containing vesicles. Furthermore, 3-mercaptopropionic acid and hexanoyl-CoA, inhibitors of long-chain and medium-chain ACDs, respectively, induced dissociation of long-chain acyl-coenzyme A dehydrogenase and/or medium-chain acyl-coenzyme A dehydrogenase from IRAP in vitro as well as recruitment of GLUT4 to the plasma membrane and stimulation of glucose transport activity in permeabilized 3T3-L1 adipocytes. These findings suggest that ACDs are localized on GLUT4-containing vesicles via association with IRAP in a manner dependent on its dileucine motif and play a role in retention of GLUT4-containing vesicles to an intracellular compartment.

Allele frequencies are rather constant among different ethnic groups in many genetic polymorphisms, but some polymorphisms vary in the allele frequency depending on the time when the germ-line base exchanges occurred in the history of humans and on the adaptability of the phenotypes to given environment. This review documented the allele frequencies of polymorphisms pertaining to cancer risk for Japanese, Koreans, and Chinese. Twenty-five polymorphisms of 21 genes whose allele frequencies were available for at least two out of the three ethnic groups were selected. They were ALDH2 Glu487Lys, COMT Val158Met, CYP1A1 MspI and Val/Ile, CYP1B1 Leu432Val, CYP2E1 RsaI, CYP17 T-34C, ER C975G, GSTM1, GSTT1, GSTP1 Ile105Val, IL-1B C-511T, IL-1RN 86-bp VNTR (variable number of tandem repeats), MTHFR C677T and A1298C, NAT1, NAT2, NQO1 Pro187Ser, OGG1 Ser326Cys, p21 Ser31Arg, p53 Arg72Pro, TNF-A G-308A and G-238A, and XRCC1 Arg194Trp and Arg399Gln. The allele frequencies were found for 24 in Japanese, 16 in Koreans, and 24 in Chinese. All of the polymorphisms had similar allele frequencies for these ethnic groups, except the following polymorphisms; ALDH2 Glu487Lys whose Lys allele was more common for Japanese and Taiwanese, COMT Val158Met whose Met allele was more common for Japanese, and NAT2 rapid/slow whose slow alleles were more common for Chinese. When compared with the allele frequencies among Caucasians, the following minor alleles were more frequent among Japanese/Koreans/Chinese; ALDH2 478Lys, CYP1A1 m1 and m2, CYP2E1 c2, ER 975G, GSTT1 null, NAT1 *10, NQO1 187Ser, OGG1 326Cys, p21 31Arg, and XRCC1 194Trp, and less frequent in COMT 158Met, GST-P1 105Val, IL-1RN non-4R, MTHFR 1298C, and TNF-A -308A. The differences in genetic background may affect the impact on the lifestyle factors and/or genotypes examined in epidemiological studies. However, the influences of the variations in the allele frequency seemed to be limited among Japanese, Koreans, and Chinese. The substantial differences in the allele frequency from Caucasians could modify the influences of lifestyle factors and polymorphism genotypes, resulting in the inconsistent results of epidemiologic studies.

e tested whether polymorphic variations in glutathione S-transferase genes (GSTM1, GSTT1, GSTP1) and interleukin-1 (IL-1beta and IL-1RN) genes confer susceptibility to mucosa-associated lymphoid tissue lymphomas (MALT) in a Chinese population. The rates of GSTM1, GSTP1, IL-1beta and IL-1RN genotypes did not differ between patients and controls. However, GSTT1 null genotypes were significantly more common in patients with MALT lymphomas (43/75 vs. 138/321, p=0.029; OR=1.8, 95% CI: 1.1-3.0) than in controls. Our results suggest that a glutathione S-transferase defect plays a role in MALT lymphoma.
