Abstract
Objective Low HDL-C (high-density lipoprotein cholesterol) is the most frequent dyslipidemia in Mexicans, but few studies have examined the underlying genetic basis. Our purpose was to identify genetic variants associated with HDL-C levels and cardiovascular risk in the Mexican population. Approach and Results A genome-wide association studies for HDL-C levels in 2335 Mexicans, identified four loci associated with genome-wide significance: CETP, ABCA1, LIPC, and SIDT2. The SIDT2 missense Val636Ile variant was associated with HDL-C levels and was replicated in 3 independent cohorts (P=5.9×10−18 in the conjoint analysis). The SIDT2/Val636Ile variant is more frequent in Native American and derived populations than in other ethnic groups. This variant was also associated with increased ApoA1 and glycerophospholipid serum levels, decreased LDL-C (low-density lipoprotein cholesterol) and ApoB levels, and a lower risk of premature CAD. Because SIDT2 was previously identified as a protein involved in sterol transport, we tested whether the SIDT2/Ile636 protein affected this function using an in vitro site-directed mutagenesis approach. The SIDT2/Ile636 protein showed increased uptake of the cholesterol analog dehydroergosterol, suggesting this variant affects function. Finally, liver transcriptome data from humans and the Hybrid Mouse Diversity Panel are consistent with the involvement of SIDT2 in lipid and lipoprotein metabolism. Conclusions This is the first genome-wide association study for HDL-C levels seeking associations with coronary artery disease in the Mexican population. Our findings provide new insight into the genetic architecture of HDL-C and highlight SIDT2 as a new player in cholesterol and lipoprotein metabolism in humans.

Abstract
OBJECTIVE Previous studies have shown that deficiency of M-CSF (macrophage colony-stimulating factor; or CSF1 [colony stimulating factor 1]) dramatically reduces atherosclerosis in hyperlipidemic mice. We characterize the underlying mechanism and investigate the relevant sources of CSF1 in lesions. Approach and Results: We quantitatively assessed the effects of CSF1 deficiency on macrophage proliferation and apoptosis in atherosclerotic lesions. Staining of aortic lesions with markers of proliferation, Ki-67 and bromodeoxyuridine, revealed around 40% reduction in CSF1 heterozygous (Csf1+/-) as compared with WT (wild type; Csf1+/+) mice. Similarly, staining with a marker of apoptosis, activated caspase-3, revealed a 3-fold increase in apoptotic cells in Csf1+/- mice. Next, we determined the cellular sources of CSF1 contributing to lesion development. Cell-specific deletions of Csf1 in smooth muscle cells using SM22α-Cre (smooth muscle protein 22-alpha-Cre) reduced lesions by about 40%, and in endothelial cells, deletions with Cdh5-Cre (VE-cadherin-Cre) reduced lesions by about 30%. Macrophage-specific deletion with LysM-Cre (lysozyme M-Cre), on the other hand, did not significantly reduce lesions size. Transplantation of Csf1 null (Csf1-/-) mice bone marrow into Csf1+/+ mice reduced lesions by about 35%, suggesting that CSF1 from hematopoietic cells other than macrophages contributes to atherosclerosis. None of the cell-specific knockouts affected circulating CSF1 levels, and only the smooth muscle cell deletions had any effect on the percentage monocytes in the circulation. Also, Csf1+/- mice did not exhibit significant differences in Ly6Chigh/Ly6Clow monocytes as compared with Csf1+/+. CONCLUSIONS CSF1 contributes to both macrophage proliferation and survival in lesions. Local CSF1 production by smooth muscle cell and endothelial cell rather than circulating CSF1 is the primary driver of macrophage expansion in atherosclerosis.

Abstract
BACKGROUND AND AIMS Heparin-binding EGF-like growth factor (HB-EGF) is a representative EGF family member that interacts with EGFR under diverse stress environment. Previously, we reported that the HB-EGF-targeting using antisense oligonucleotide (ASO) effectively suppressed an aortic aneurysm in the vessel wall and circulatory lipid levels. In this study, we further examined the effects of the HB-EGF ASO administration on the development of hyperlipidemia-associated atherosclerosis using an atherogenic mouse model. METHODS AND RESULTS The male and female LDLR deficient mice under Western diet containing 21% fat and 0.2% cholesterol content were cotreated with control and HB-EGF ASOs for 12 weeks. We observed that the HB-EGF ASO administration effectively downregulated circulatory VLDL- and LDL-associated lipid levels in circulation; concordantly, the HB-EGF targeting effectively suppressed the development of atherosclerosis in the aorta. An EGFR blocker BIBX1382 administration suppressed the hepatic TG secretion rate, suggesting a positive role of the HB-EGF signaling for the hepatic VLDL production. We newly observed that there was a significant improvement of the insulin sensitivity by the HB-EGF ASO administration in a mouse model under the Western diet as demonstrated by the improvement of the glucose and insulin tolerances. CONCLUSION The HB-EGF ASO administration effectively downregulated circulatory lipid levels by suppressing hepatic VLDL production rate, which leads to effective protection against atherosclerosis in the vascular wall.

Abstract
We profiled and analyzed 283 metabolites representing eight major classes of molecules including Lipids, Carbohydrates, Amino Acids, Peptides, Xenobiotics, Vitamins and Cofactors, Energy Metabolism, and Nucleotides in mouse liver of 104 inbred and recombinant inbred strains. We find that metabolites exhibit a wide range of variation, as has been previously observed with metabolites in blood serum. Using genome‐wide association analysis, we mapped 40% of the quantified metabolites to at least one locus in the genome and for 75% of the loci mapped we identified at least one candidate gene by local expression QTL analysis of the transcripts. Moreover, we validated 2 of 3 of the significant loci examined by adenoviral overexpression of the genes in mice. In our GWAS results, we find that at significant loci the peak markers explained on average between 20 and 40% of variation in the metabolites. Moreover, 39% of loci found to be regulating liver metabolites in mice were also found in human GWAS results for serum metabolites, providing support for similarity in genetic regulation of metabolites between mice and human. We also integrated the metabolomic data with transcriptomic and clinical phenotypic data to evaluate the extent of co‐variation across various biological scales.

Abstract
BACKGROUND AND PURPOSE Recently identified molecular subgroups of medulloblastoma have shown potential for improved risk stratification. We hypothesized that distinct MR imaging features can predict these subgroups. MATERIALS AND METHODS All patients with a diagnosis of medulloblastoma at one institution, with both pretherapy MR imaging and surgical tissue, served as the discovery cohort (n = 47). MR imaging features were assessed by 3 blinded neuroradiologists. NanoString-based assay of tumor tissues was conducted to classify the tumors into the 4 established molecular subgroups (wingless, sonic hedgehog, group 3, and group 4). A second pediatric medulloblastoma cohort (n = 52) from an independent institution was used for validation of the MR imaging features predictive of the molecular subtypes. RESULTS Logistic regression analysis within the discovery cohort revealed tumor location (P < .001) and enhancement pattern (P = .001) to be significant predictors of medulloblastoma subgroups. Stereospecific computational analyses confirmed that group 3 and 4 tumors predominated within the midline fourth ventricle (100%, P = .007), wingless tumors were localized to the cerebellar peduncle/cerebellopontine angle cistern with a positive predictive value of 100% (95% CI, 30%-100%), and sonic hedgehog tumors arose in the cerebellar hemispheres with a positive predictive value of 100% (95% CI, 59%-100%). Midline group 4 tumors presented with minimal/no enhancement with a positive predictive value of 91% (95% CI, 59%-98%). When we used the MR imaging feature-based regression model, 66% of medulloblastomas were correctly predicted in the discovery cohort, and 65%, in the validation cohort. CONCLUSIONS Tumor location and enhancement pattern were predictive of molecular subgroups of pediatric medulloblastoma and may potentially serve as a surrogate for genomic testing.

Abstract
The paraoxonase (PON) gene family consists of three members, PON1, PON2 and PON3. All PON proteins possess antioxidant properties and lipo-lactonase activities, and are implicated in the pathogenesis of several inflammatory diseases including atherosclerosis, Alzheimer's, Parkinson's, diabetes and cancer. Despite the role of PON proteins in critical cellular functions and associated pathologies, the physiological substrates and molecular mechanisms by which PON proteins function as anti-inflammatory proteins remain largely unknown. PON1 is found exclusively extracellular and associated solely with high-density lipoprotein (HDL) particles in the circulation, and, in part, confers the anti-oxidant and anti-inflammatory properties associated with HDL. Recent studies demonstrated that the intracellular PON proteins; PON2 and PON3 (i) are associated with mitochondria and mitochondria-associated membranes, (ii) modulate mitochondria-dependent superoxide production, and (iii) prevent apoptosis. Overexpression of PON2 and PON3 genes protected (i) mitochondria from antimycin or oligomycin mediated mitochondrial dysfunction and (ii) ER stress and ER stress mediated mitochondrial dysfunction. These studies illustrate that the anti-inflammatory effects of PON2 and PON3 may, in part, be mediated by their role in mitochondrial and associated organelle function. Since oxidative stress as a result of mitochondrial dysfunction is implicated in the development of inflammatory diseases including atherosclerosis and cancer, these recent studies on PON2 and PON3 proteins may provide a mechanism for the scores of epidemiological studies that show a link between PON genes and numerous inflammatory diseases. Understanding such mechanisms will provide novel routes of intervention in the treatment of diseases associated with pro-inflammatory oxidative stress.

Abstract
Recent studies have revealed a novel route for cholesterol disposal through intestine known as transintestinal cholesterol efflux (TICE) that significantly contributes to fecal neutral sterol loss. This pathway is an integral part of reverse cholesterol transport (RCT), yet major mechanisms regulating TICE are not well understood. Using an unbiased transcriptional profiling approach in mouse models of augmented TICE, we found that hepatic expression of the enzyme Flavin monoxygenase 3 (FMO3) was dramatically repressed. At the same time we identified this enzyme through transcriptional profiling, it was reported that plasma levels of its product trimethylamineoxide (TMAO) are highly predictive of atheroslcerosis in humans, and TMAO is proatherogenic in mice. To further understand FMO3’s role as a regulator of cholesterol metabolism we used antisense oligonucleotides (ASO) to knockdown FMO3 expression in mouse liver in C57BL/6 mice fed either low (0.02%) or high (0.2%) levels of dietary cholesterol. As expected, FMO3 knockdown (>90% knockdown in the liver) increased the TMA/TMAO ratio in plasma more than 3-fold. Interestingly, knockdown of FMO biliary cholesterol levels were reduced by 60%, whereas fecal cholesterol loss was quite normal in FMO3 ASO treated mice fed a high cholesterol diet, which phenocopies a previously described mouse model where TICE predominates (NPC1L1-liver transgenic mice). ASO-mediated knockdown of FMO3 also unexpectedly reduced hepatic cholesteryl ester (CE) storage by 70% in mice fed 0.2% cholesterol. In parallel, knockdown of FMO3 reduces plasma VLDL cholesterol levels and the secretion rate of VLDL cholesteryl ester, but not triacylglycerol in cholesterol fed mice. FMO3 knockdown also reduced the hepatic expression of several liver X receptor (LXR) target genes, while increasing expression of genes involved in cholesterol synthesis. Collectively, these studies have identified FMO3 as a novel regulator of hepatic cholesterol metabolism and TICE. Given that plasma levels of FMO3’s product (TMAO) are strongly associated with atherosclerosis development in humans, and production of TMAO promotes atherosclerosis in mice, these studies have important implications for future cardiovascular drug discovery.

Abstract
RATIONALE Mutations of the orphan transporter ABCC6 (ATP-binding cassette, subfamily C, member 6) cause the connective tissue disorder pseudoxanthoma elasticum. ABCC6 was thought to be located on the plasma membrane of liver and kidney cells. OBJECTIVE Mouse systems genetics and bioinformatics suggested that ABCC6 deficiency affects mitochondrial gene expression. We therefore tested whether ABCC6 associates with mitochondria. METHODS AND RESULTS We found ABCC6 in crude mitochondrial fractions and subsequently pinpointed its localization to the purified mitochondria-associated membrane fraction. Cell-surface biotinylation in hepatocytes confirmed that ABCC6 is intracellular. Abcc6-knockout mice demonstrated mitochondrial abnormalities and decreased respiration reserve capacity. CONCLUSIONS Our finding that ABCC6 localizes to the mitochondria-associated membrane has implications for its mechanism of action in normal and diseased states.

Abstract
PURPOSE OF REVIEW During the past decade, paraoxonase 1, a HDL-associated protein, has been demonstrated to be an important contributor to the antioxidant capacity of HDL. Studies using paraoxonase 1 null mice by gene targeting and transgenic mice corroborated the hypothesis that paraoxonase 1 protects against atherosclerosis. In contrast to paraoxonase 1, the other two members of the paraoxonase gene family, namely paraoxonase 2 and paraoxonase 3, are either undetectable (paraoxonase 2) or detected at very low levels (paraoxonase 3) on HDL, and are considered to participate in intracellular antioxidant mechanisms. In this review, we summarize studies reported in the past 2 years suggesting a protective role for paraoxonase 2 and paraoxonase 3 in the development of atherosclerosis in mice. RECENT FINDINGS Adenovirus-mediated expression of human paraoxonase 2 or paraoxonase 3 proteins protects against the development of atherosclerosis in apolipoprotein E-deficient mice. Paraoxonase 2-deficient mice develop significantly larger atherosclerotic lesions than their wild-type and heterozygous counterparts on an atherogenic diet despite having lower levels of apolipoprotein B-containing lipoproteins. Atherosclerotic lesions were significantly lower in male hPON3Tg/LDLR null mice than in LDLR null mice on a western diet. SUMMARY We conclude that, in addition to paraoxonase 1, both paraoxonase 2 and paraoxonase 3 proteins are protective against the development of atherosclerosis in mice. These findings underscore the utility of all members of the paraoxonase gene family as therapeutic targets for the treatment of atherosclerosis.

Abstract
OBJECTIVE We have previously reported that human paraoxonase 3 (PON3) is an HDL-associated protein capable of preventing LDL oxidation in vitro. The objective of the present study was to determine whether elevated levels of human PON3 in mice could protect against the progression of atherosclerosis in vivo. METHODS AND RESULTS Twenty-six week-old apolipoprotein E-deficient mice were injected with 3x10(11) particles of adenovirus expressing either GFP alone (AdGFP) or together with human PON3 (AdPON3). Three weeks after injection, lesion area was significantly lower in AdPON3-treated mice compared with AdGFP controls. Serum from AdPON3 mice contained significantly lower levels of lipid hydroperoxides and exhibited an enhanced potential to efflux cholesterol from cholesterol-loaded macrophages. In addition, LDL was less susceptible to oxidation, whereas HDL was more capable of protecting against LDL oxidation. Exogenous human PON3 was not detected in the serum or HDL and more surprisingly we demonstrate that endogenous mouse PON3 is not associated with HDL, suggesting that the antioxidant function of PON3 is at the cellular level in mice. CONCLUSIONS This study demonstrates for the first time that PON3 enhances the antiatherogenic capacity of serum and protects against the progression of atherosclerosis in vivo.

Abstract
In vitro studies have suggested that a fraction of human high density lipoprotein (HDL), termed trypanosome lysis factor (TLF), can protect against trypanosome infection. We examined the involvement of two proteins located in the TLF fraction, apolipoprotein A-II (apoA-II) and paraoxonase 1 (PON1), against trypanosome infection. To test whether PON1 is involved in trypanosome resistance, we infected human PON1 transgenic mice, PON1 knockout mice, and wild-type mice with Trypanosoma congolense. When challenged with the same dosage of trypanosomes, mice overexpressing PON1 lived significantly longer than wild-type mice, and mice deficient in PON1 lived significantly shorter. In contrast, mice overexpressing another HDL associated protein, apoA-II, had the same survival as wild-type mice. Together, these data suggest that PON1 provides protection against trypanosome infection. In vitro studies using T. brucei brucei indicated that HDL particles containing PON1 and those depleted of PON1 did not differ in their lysis ability, suggesting that protection by PON1 is indirect. Our data are consistent with an in vivo role of HDL protection against trypanosome infection.

Abstract
Here we report a high-quality draft genome sequence of the domestic dog (Canis familiaris), together with a dense map of single nucleotide polymorphisms (SNPs) across breeds. The dog is of particular interest because it provides important evolutionary information and because existing breeds show great phenotypic diversity for morphological, physiological and behavioural traits. We use sequence comparison with the primate and rodent lineages to shed light on the structure and evolution of genomes and genes. Notably, the majority of the most highly conserved non-coding sequences in mammalian genomes are clustered near a small subset of genes with important roles in development. Analysis of SNPs reveals long-range haplotypes across the entire dog genome, and defines the nature of genetic diversity within and across breeds. The current SNP map now makes it possible for genome-wide association studies to identify genes responsible for diseases and traits, with important consequences for human and companion animal health.

Abstract
We investigated the role of HDL-associated paraoxonase 1 (PON1) in HDL-mediated macrophage cholesterol efflux by using HDL derived from wild type mice (Control-HDL), from human PON1-transgenic mice (HDL-PON1Tg) or from PON1-knockout mice (HDL-PON1(0)). Cholesterol efflux from mouse peritoneal macrophages (MPM) or from J774 A.1 macrophage cell line by HDL-PON1Tg, was significantly increased (by 60%) compared to HDL-PON1(0). We demonstrated that this PON1 effect was associated with an increased HDL binding to the cells, as the binding of HDL-PON1Tg (or HDL-PON1(0) that was enriched with PON1) was increased by 50% compared to that of HDL-PON1(0). Using either a cAMP analogue, to increase ABCA1 receptor expression, or rabbit anti-mouse SR-BI specific antibody to block the SR-BI receptor, PON1 stimulation of HDL binding and of HDL-mediated macrophage cholesterol efflux, were both found to involve the ABCA1 transporter. Studies with PON1 specific inhibitors revealed that PON1 activity was required for its stimulation of HDL-mediated macrophage cholesterol efflux. Upon incubation of macrophages with Control-HDL or with HDL-PON1Tg, macrophage lysophosphatidylcholine (LPC) content was increased by 3.7- and 7.5-fold, respectively. Such an LPC enrichment of macrophages resulted in up to 60% increased HDL binding to the cells, and a 41% increased HDL-mediated cholesterol efflux. Similarly, macrophage loading with LPC (by either adding LPC, or PON1 or phospholipase A(2)) significantly increased apolipoprotein A-I (apoA-I) mediated cholesterol efflux by 104, 65 and 56%, respectively, in ABCA1 overexpressing macrophages. We conclude that HDL-associated PON1 may contribute to the attenuation of atherosclerosis development by its ability to act on macrophage phospholipids, to form LPC, in turn, stimulates HDL binding and HDL-mediated macrophage cholesterol efflux via the ABCA1 transporter.

Abstract
High-density lipoproteins (HDL) in the basal state are anti-inflammatory, capable of destroying oxidized lipids that generate an inflammatory response. However, HDL during acute inflammation are altered and become pro-inflammatory. This "chameleon-like" nature of HDL is considered to be due to the complex composition of HDL. The data reviewed here demonstrate the key role of HDL in modulating inflammation and its implications for atherogenesis.

Abstract
Oxidation of low density lipoprotein (LDL) phospholipids containing arachidonic acid at the sn-2 position occurs when a critical concentration of "seeding molecules" derived from the lipoxygenase pathway is reached in LDL. When this critical concentration is reached, the nonenzymatic oxidation of LDL phospholipids produces a series of biologically active, oxidized phospholipids that mediate the cellular events seen in the developing fatty streak. Normal high density lipoprotein (HDL) contains at least 4 enzymes as well as apolipoproteins that can prevent the formation of the LDL-derived oxidized phospholipids or inactivate them after they are formed. In the sense that normal HDL can prevent the formation of or inactivate these inflammatory LDL-derived oxidized phospholipids, normal HDL is anti-inflammatory. HDL from mice that are genetically predisposed to diet-induced atherosclerosis became proinflammatory when the mice are fed an atherogenic diet, injected with LDL-derived oxidized phospholipids, or infected with influenza A virus. Mice that were genetically engineered to be hyperlipidemic on a chow diet and patients with coronary atherosclerosis, despite normal lipid levels, also had proinflammatory HDL. It is proposed that LDL-derived oxidized phospholipids and HDL may be part of a system of nonspecific innate immunity and that the detection of proinflammatory HDL may be a useful marker of susceptibility to atherosclerosis.

Abstract
To identify potential transactivators of pdx-1, we sequenced approximately 4.5 kilobases of the 5' promoter region of the human and chicken homologs, assuming that sequences conserved with the mouse gene would contain critical cis-regulatory elements. The sequences associated with hypersensitive site 1 (HSS1) represented the principal area of homology within which three conserved subdomains were apparent: area I (-2694 to -2561 base pairs (bp)), area II (-2139 to -1958 bp), and area III (-1879 to -1799 bp). The identities between the mouse and chicken/human genes are very high, ranging from 78 to 89%, although only areas I and III are present within this region in chicken. Pancreatic beta cell-selective expression was shown to be controlled by mouse and human area I or area II, but not area III, from an analysis of pdx-1-driven reporter activity in transfected beta- and non-beta cells. Mutational and functional analyses of conserved hepatic nuclear factor 3 (HNF3)-like sites located within area I and area II demonstrated that activation by these regions was mediated by HNF3beta. To determine if a similar regulatory relationship might exist within the context of the endogenous gene, pdx-1 expression was measured in embryonic stem cells in which one or both alleles of HNF3beta were inactivated. pdx-1 mRNA levels induced upon differentiation to embryoid bodies were down-regulated in homozygous null HNF3beta cells. Together, these results suggest that the conserved sequences represented by areas I and II define the binding sites for factors such as HNF3beta, which control islet beta cell-selective expression of the pdx-1 gene.

Abstract
Taurine is an abundant amino acid found in mammalian tissues and it has been suggested to have cytoprotective functions. The aim of the present study was to determine if taurine had the potential to reduce oxidative stress associated with metal-stimulated catecholamine oxidation. Taurine and structural analogs of taurine were tested for their ability to inhibit metal-stimulated quinone formation from dopamine or L-dopa. Oxidative damage to proteins and lipids were also assessed in vitro and the effects of taurine were determined. Taurine (20 mM) was found to decrease significantly ferric iron (50-500 microM)- and manganese (10 microM)-stimulated L-dopa or dopamine oxidation. Taurine had no effect on zinc-induced dopamine oxidation and slightly potentiated copper- and NaIO(4)-stimulated quinone formation. Ferric iron-stimulated lipid peroxidation was not affected by taurine (1-20 mM). Protein carbonyl formation induced by ferric iron (500 microM) and L-dopa (500 microM) was significantly reduced by 10 mM taurine. The cytotoxicity of L-dopa (250 microM) and ferric chloride (75 microM) to LLC-PK(1) cells was attenuated by 10 mM taurine or hypotaurine. Homotaurine alone stimulated L-dopa oxidation and potentiated the cytotoxic effects of ferric iron. Homotaurine was found to be cytotoxic when combined with L-dopa or L-dopa/iron. In contrast, hypotaurine inhibited quinone formation and protected LLC-PK(1) cells. These studies suggest that taurine may exhibit cytoprotective effects against the oxidation products of catecholamines by acting as a scavenger for free radicals and cytotoxic quinones.

Abstract
We retrospectively evaluated 233 incident patients (61% black, 27% white, and 12% Hispanic/Asian) to our peritoneal dialysis (PD) program from January 1987 to September 1997 to identify any possible racial differences in patient survival. Information collected included clinical features, comorbid conditions, nutritional status, and dialysis dose at initiation of dialysis. The average age was 52 +/- 16 (SD) years, and 49% were men. Diabetes mellitus was present in 41% of patients. Overall follow-up was 31 +/- 24 (median 26) months during which time 21% of patients underwent transplant, 29% of patients transferred to hemodialysis (HD), and 42% of patients died. The Cox proportional hazards analysis, based on intent-to-treat, identified age (RR: 1.03), race (RR: 2.35, white versus black), cardiac disease (RR: 1.97), and serum albumin (RR: 0. 44) to independently predict mortality. Further analysis was performed based on diabetic status, and the analysis identified age (RR: 1.06), race (RR: 2.45, white versus black), and peripheral vascular disease (RR: 2.88) as predictors of mortality in diabetic patients. In nondiabetic patients, age (RR: 1.03), race (RR: 2.24, white versus black), cardiac disease (RR: 2.48), cerebrovascular disease (RR: 3.17), and serum albumin (RR: 0.39) were significant predictors of mortality. The significance of race persisted even after adjusting patients transferring to hemodialysis. The adjusted patient survival at 1, 2, and 5 years was 94%, 87% and 53% for black patients, and 86%, 72%, and 23% for white patients. The adjusted patient survival in diabetics at 1, 2, and 5 years was 92%, 79%, and 37% for black patients, and 82%, 56%, and 9% for white patients. The adjusted patient survival in nondiabetics at 1, 2, and 5 years was 94%, 91%, and 63% for black patients, and 88%, 82%, and 35% for white patients. In conclusion, long-term patient survival is better for black patients than white patients in our peritoneal dialysis program. Peritoneal dialysis should be considered a viable dialytic option for black patients entering an end-stage renal disease program.

Abstract
Genetic studies have shown that mutations in the gene encoding hepatocyte nuclear factor (HNF)-4alpha, a member of the steroid/thyroid hormone receptor superfamily, give rise to early-onset type 2 diabetes (MODY1). The functional properties of mutant HNF-4alpha proteins and the molecular mechanisms by which they impair insulin secretion are largely unknown. In the present study, we have investigated transcriptional activation, DNA binding properties, and protein dimerization activity of three HNF-4alpha missense mutations--HNF4(R127W), HNF4(V255M), and HNF4(E276Q)--that have been associated with type 2 diabetes. We demonstrate that HNF4(E276Q) has lost its ability to bind to HNF-4 consensus binding sites and activate transcription. HNF4(E276Q) had no effect on the functional activity of wild-type HNF-4alpha in the pancreatic beta-cell line HIT-T15, but it exhibited weak dominant-negative activity in other cell types. Analysis of HNF4(E276Q) protein showed that it exists in two forms: a full length 54-kDa protein and a 40-kDa COOH-terminal protein lacking the NH2-terminal transactivation domain and the DNA binding domain. Immunoprecipitation experiments indicate that this truncated protein can bind to wild-type HNF-4alpha and may be responsible for the weak dominant-negative effects seen in these cells. In addition, we show that the transcriptional transactivation of HNF4(R127W) and HNF4(V255M) is indistinguishable from that of wild-type HNF-4alpha, suggesting that they are sequence polymorphisms. Our results demonstrate that HNF4(E276Q) is a loss-of-function mutation and that it identifies glutamic acid 276 in alpha-helix 8 of the ligand-binding domain of HNF-4alpha protein as a critical residue for DNA binding, transcriptional activation, and protein stability in vivo.

Abstract
Paraoxonase (PON1) hydrolyses organophosphate insecticides and nerve gases and is responsible for determining the selective toxicity of these compounds in mammals. Human PON1 has two genetic polymorphisms giving rise to amino-acid substitutions at positions 55 and 192. The 192 polymorphism is the major determinant of the PON1 activity polymorphism towards organophosphates. However, the 55 polymorphism also modulates activity. Ex vivo, the PON1 polymorphisms are important in determining the capacity of HDL to protect LDL against oxidative modification in vitro and this may explain the relationship between the PON1 alleles and coronary heart disease in case-control studies. In recent case-control studies serum PON1 concentration and activity were also found to be decreased in coronary heart disease (CHD) independent of the PON1 polymorphism, and in diabetes serum PON1 specific activity decrease is also independent of the PON1 genetic polymorphism. HDL from transgenic mice lacking PON1 fails to protect LDL against oxidative modification. Thus PON1 may be a determinant of resistance to the development of atherosclerosis by protecting lipoproteins against oxidative modification, perhaps by hydrolysing phospholipid and cholesteryl-ester hydroperoxides.

Abstract
Glucose and other reducing sugars react with proteins by a nonenzymatic, post-translational modification process called nonenzymatic glycosylation or glycation. The sugar-derived carbonyl group adds to a free amine, forming a reversible adduct which over time rearranges to produce a class of products termed advanced-glycation end-products (AGEs). These remain irreversibly bound to macromolecules and can covalently crosslink proximate amino groups. The formation of AGEs on long-lived connective tissue and matrix components accounts largely for the increase in collagen crosslinking that accompanies normal ageing and which occurs at an accelerated rate in diabetes. AGEs can activate cellular receptors and initiate a variety of pathophysiological responses. They modify an appreciable fraction of circulating low-density lipoproteins preventing uptake of these particles by their high-affinity tissue receptors. Advanced glycation has also been implicated in the pathology of Alzheimer's disease. Because AGEs may form by a pathway involving reactive alpha-dicarbonyl intermediates, we investigated a potential pharmacological strategy for selectively cleaving the resultant glucose-derived protein crosslinks. We now describe a prototypic AGE crosslink 'breaker', N-phenacylthiazolium bromide (PTB), which reacts with and cleaves covalent, AGE-derived protein crosslinks. The ability of PTB to break AGE crosslinks in vivo points to the importance of an alpha-dicarbonyl intermediate in the advanced glycation pathway and offers a potential therapeutic approach for the removal of established AGE crosslinks.

Abstract
The poly(A) binding protein (PABP), a conserved protein that binds to the 3' poly(A) tail on mRNAs in eukaryotic cells, has been implicated in the regulation of mRNA stability and translation. Two PABP cDNAs with different sequences were isolated from mouse testis cDNA libraries. The predicted amino acid sequence of one, PABP1, is nearly identical (98.9%) to human liver PABP, while 80% of the amino acids of the second, PABPt, are identical to mouse and human PABPs. Northern blots reveal that there is one major PABP mRNA species in liver, muscle, kidney, and brain, two in spleen, and at least four in testis. The levels of PABP mRNA in testis are 5-10-fold higher than in these somatic tissues, but surprisingly the vast majority of all PABP mRNA size variants sediment more slowly than single ribosomes, indicating strong translational repression. Reverse transcriptase-polymerase chain reaction assays demonstrate that PABPt mRNAs are abundant only in testis. Northern blots of RNAs purified from highly enriched spermatogenic cells show that the high levels, multiple sizes of PABP mRNAs, and the PABPt mRNA are present in meiotic and early haploid spermatogenic cells, and are sharply reduced in late haploid cells. Comparison of the binding of PABP1 and PABPt to poly(A) Sepharose in vitro revealed subtle differences, even though PABPt contains substitutions for highly conserved aromatic amino acids that are thought to be necessary for binding to poly(A). The existence of two PABP isoforms in mouse spermatogenic cells could influence cytoplasmic gene expression during spermatogenesis.

Abstract
The mitochondrial selenoprotein is a major structural protein of the keratinous mitochondrial capsule in mammalian sperm, a structure that functions in shaping mitochondria into the helical sheath surrounding the flagellum. A cDNA clone (Kleene et al., 1990) was isolated previously encoding a protein whose predicted size and amino acid content of > 20% cysteine and proline closely resembled a selenoprotein in the bull mitochondrial capsule. The sequences of additional cDNAs and genomic DNA reported here reveal that the mouse mitochondrial capsule selenoprotein reading frame begins 54 codons further upstream than previously reported. Significantly, these 54 codons contain three in-phase UGA codons, which normally signify stop but encode selenocysteine in bacterial and mammalian selenoproteins. The coding region of the mitochondrial capsule selenoprotein gene is interrupted by a single intron. S1 mapping and primer extension demonstrate that the vast majority of MCS mRNAs are spliced using consensus 5' and 3' slice junctions in mammalian cells. However, two cDNAs have been identified that apparently represent rare mRNA variants produced by use of cryptic splice sites.

Abstract
The gene encoding the testis-specific basic chromosomal protein, mouse transition protein 2, is split by a single small intron that falls between the first and second nucleotides of a codon. Since the genes encoding protamines 1 and 2 and transition protein 1 in mammals contain a single intron in the same position, protamines and transition proteins appear to be evolutionarily related.

Abstract
Using an Escherichia coli gene expression system, we have engineered human hemoglobin (Hb) mutants having the distal histidine (E7) and valine (E11) residues replaced by other amino acids. The interaction between the mutated distal residues and bound carbon monoxide has been studied by Soret-excited resonance Raman spectroscopy. The replacement of Val-E11 by Ala, Leu, Ile, and Met has no effect on the v(C-O), v(Fe-CO) stretching or delta(Fe-C-O) bending frequencies in both the alpha and beta subunits of Hb, although some of these mutations affect the CO affinity as much as 40-fold. The strain imposed on the protein by the binding of CO is not localized in the Fe-CO bond and is probably distributed among many bonds in the globin. The replacement of His-E7 by Val or Gly brings the stretching frequencies v(Fe-CO) and v(C-O) close to those of free heme complexes. In contrast, the substitution of His-E7 by Gln, which is flexible and polar, produces no effects on the resonance Raman spectrum of either alpha- or beta-globin. The replacement of His-E7 of beta-globin by Phe shows the same effect as replacement by Gly or Val. Therefore, the steric bulk of the distal residues is not the primary determinant of the Fe-CO ligand vibrational frequencies. The ability of both histidine and glutamine to alter the v(C-O), v(Fe-CO), or delta(Fe-C-O) frequencies may be attributed to the polar nature of their side chains which can interact with bound CO in a similar manner.

Abstract
The hydroxyl group of Tyr alpha 42 in human hemoglobin forms a hydrogen bond with the carboxylate of Asp beta 99 which is considered to be one of the most important hydrogen bonds for stabilizing the "T-state." However, no spontaneous mutation at position 42 of the alpha subunit has been reported, and the role of the tyrosine has not been tested experimentally. Two artificial human mutant hemoglobins in which Tyr alpha 42 was replaced by phenylalanine or histidine were synthesized in Escherichia coli, and their proton NMR spectra were studied with particular attention to the hyperfine-shifted and hydrogen-bonded proton resonances. The site-directed mutagenesis of the Tyr alpha 42----Phe removes the hydrogen bond described above and prevents transition to the T-state so that the mutant Hb is rather similar to the "R-state" even when deoxygenated. On the other hand, the mutation from tyrosine to histidine causes less drastic structural changes, and its quaternary and tertiary structures are almost the same as native deoxy-Hb A. This may be attributed to the formation of a new hydrogen bond between His alpha 1(42) and Asp beta 2(99). These observations indicate that the hydrogen bond formed between Tyr alpha 42 and Asp beta 99 is required to convert unliganded Hb to the T-state.

Abstract
Hemoglobin Brockton [beta 138 (H16) Ala----Pro] is an unstable variant associated with a mild anemia. It has the same electrophoretic mobility as and cannot be resolved from Hb A. Oxygen affinity measurements of blood and hemolysate do not indicate biphasic oxygen saturation, showing that the functional properties of the variant are very similar to those of Hb A. This implies that the introduction of proline into the H-helix at position 138 does not disrupt the critical inter- and intrasubunit hydrogen bonds and salt bridges at the beta carboxyl-terminal dipeptide, since these polar interactions are essential for the normal oxygen-binding properties of hemoglobin. X-ray crystallographic data are consistent with these findings and show that the consequences of the beta 138 Ala----Pro substitution are almost entirely confined to the immediate vicinity of the mutation site. Instability probably results from the inability of a buried hydrogen bond to form between Pro 138 beta and Val 134 beta.
