Key Words: Alcohol; diet, gout; resistance; obesity; purines; uric acid; seafood; vegetarian 1. Studies from different parts of the world suggest that the incidence and severity of hyperuricemia and gout may be increasing. Although most uric acid is derived from the metabolism of endogenous purine, eating foods rich in purines contributes to the total pool of uric acid. Sustained hyperuricemia is a risk factor for acute gouty arthritis, chronic tophaceous gout, renal stones, and possibly cardiovascular events and mortality. Before starting life-long urate-lowering drug therapy, it is important to identify and treat underlying disorders that may be contributing to hyperuricemia. Approximately two-thirds of total body urate is produced endogenously, whereas the remaining one-third is accounted for by dietary purines. Approximately 70% of the urate produced daily is excreted by the kidneys, while the rest is eliminated by the intestines. In men, uric acid production is increased after puberty and in women, after menopause. The predominant cause of hyperuricemia in most patients is under-excretion of urate by the kidneys. A lower clearance of urate is seen in patients with gout compared with normal controls (1). Micro-tophi will subsequently form, particularly in the cooler parts of the body such as distal extremities, olecranon bursa, and ears. Most patients with hyperuricemia will never have an attack of gout and no treatment is required although it is prudent to determine the cause of hyperuricemia and correct it, if possible. The correlation between hyperuricemia and cardiovascular events and mortality is currently controversial and under intense investigation. It is suggested that the increased cardiovascular risk linked to hyperuricemia could be related to the association with other vascular risk factors (2). Metabolic Syndrome and Hyperuricemia The connection of gout and hyperuricemia to gluttony, overindulgence in food and alcohol, and obesity dates from ancient times. In the fifth century bc, Hippocrates attributed gout to excessive intake of food and wine (3). It is relevant to recognize the strong association of the MetS with hyperuricemia. This cluster of factors is frequently referred to as the metabolic syndrome or Syndrome X (5). If there is a significant impairment of glucose tolerance, management will include the use of drugs to increase insulin sensitivity, such as the thiazolidinediones (e. The association of hyperuricemia and gout with dietary habits and the resulting insulin resistance is a likely cause (13). Data from the National Health and Nutrition Examination Survey have shown a rise in the age-adjusted prevalence of obesity from 22. Epidemiological studies have demonstrated a strong correlation between obesity and hyperuricemia (15,16). Obesity is associated with both increased production and decreased renal excretion of urate (17); 3. The Boston Veterans Administration Normative Aging Study (20) prospectively followed 2,280 healthy men, aged 21 to 81 at entry in 1963, and evaluated the incidence of gout and its associated risk factors. These observations have led to further support of weight loss to prevent recurrent gout attacks. Fat and total calorie intake, in combination with decreased physical activity, lead to overall obesity with centripetal deposition of fat (24). Centripetal obesity, in turn, is a powerful stimulus to increased insulin plasma levels and therefore, to hyperuricemia (26). Hydration is well known to assist in the prevention of hyperuricemia in the setting of malignancy, chemotherapy treatment, and nephrolithiasis. This is presumably owing to the inhibitory effect of ketones on uric acid excretion by the renal tubules (27). This study (27) suggests that the combination of fasting and alcohol appears to be mutually potentiating with regard to their effect on uric acid metabolism. After the introduction of a diet low in dairy products and high in fatty meats and carbohydrates in the early 1900s, an epidemic of obesity, hyperuricemia, and gout developed (28). Hyperuricemia and gout were rare among blacks in Africa, especially in rural areas where traditional agricultural and dairy-based diets were common. However, the frequency of hyperuricemia and gout is now increasing, particularly in urban communities, in parallel with hypertension and cardiovascular disease (30). The relationship between the consumption of purine-rich foods and the risk of devel- oping gout was evaluated in the Health Professionals Study (37). During the 12-year follow-up, validated semi-quantitative food-frequency questionnaires were used to obtain dietary information every 2 years. Little is known about the precise identity and quantity of individual purines in most foods, especially when they are cooked or processed (38). Additionally, the bioavailability of purines contained in different foods varies substantially. The variation in hyperuricemia and gout with different purine-rich foods may be explained by the variation in the amounts and types of purine content and their bioavailability for purine-to-uric-acid metabolism (3134). Animal studies in this area have shown changes in purine content following the boiling and broiling of beef, beef liver, haddock, and mushrooms. However, although these cooking processes affect purine content, the nature of the changes is not clear. On the one hand, boiling high-purine foods in water can cause a break down of the purine-containing components (called nucleic acids) and eventual freeing up of the purines for absorption. For example, in some animal studies, where rats were fed cooked versus noncooked foods, the animals eating the cooked version experienced greater absorption and excretion of purine-related compounds.
There are a number of stringencies associated with target seed site recognition and binding  generic copegus 200 mg without a prescription. A stringent seed site has perfect Watsone Crick binding and can be divided into four seed types: 8mer copegus 200 mg online, 7mer-m8 order copegus 200 mg online, 7mer-A1 buy 200 mg copegus otc, and 6mer . Each of these types differs depending on the combination of the nucleotide of position 1 and pairing at position 8. By contrast, 6mer has neither an adenine at position 1 nor base-pairing at position 8 . The thermodynamic stability of a wobble pairing (such as G:U) is comparable to that of a WatsoneCrick pairing [41,43]. The preferable nucleotide number of matches in the 30 part differs between the site that has stringent-seed pairing and the one that has moderate-stringent-seed pairing . Stringent seeds require 3e4 matches in the positions 13e16, whereas moderate-stringent-seeds require 4e5 matches in positions 13e19. Sites with this additional 30 pairing are called 3-supplementary and 30 compensatory sites . Despite extensive proling, no cancer-associated genes had been identied within this region, suggesting that miR-15a and miR-16-1 were the genomic targets of this frequent deletion. Metastasis, the process by which cancer cells disseminate from the primary tumor site and establish secondary tumors at distant sites, is the predominant cause of cancer-related deaths. Overexpression of miR-10b increases cell motility and invasiveness, effects that are reversed upon inhibition of expression, both in vitro  and in vivo , suggesting a prometastatic role for miR-10b. In breast cancer, dysregulation of miR-145 and miR-21 was associated with tumor progression, whilst reduced let-7 expression was associated with increased lymph node metastasis and proliferation capacity . In colorectal cancer, miR-21 expression is associated with tumor stage, invasion, and prognosis . Whilst in lung cancer, reduced let-7 was indicative of a poor prognosis in two independent studies [62,70]. In prostate cancer , miR-15a and miR-16-1 were demonstrated to be down-regulated in 80% of tumors. Conversely, overexpression of miR-15a and miR-16-1 reduced growth, induced apoptosis and tumor regression in a prostate cancer xenograft model. A study by Takamizawa and colleagues was the rst to identify a potential tumor suppressor role for let-7 , demon- strating the down-regulation of let-7 in lung cancer, with low expression also associated with a shorter postoperative survival time. Overexpression of let-7 signicantly inhibited growth in lung cancer cells, suggesting a functional role for let-7 in modulating tumorigenesis. This is supported by several studies that have demonstrated the antiproliferative effects of let-7 in lung , thyroid , and prostate  cancer. Furthermore, let-7 has been demonstrated to inhibit tumor growth in vivo [77,78], further supporting a tumor suppressor role. This suggests that the frequent down-regulation of let-7 seen in multiple cancers provides a mechanism for tumor development and progression via increased expression of these gene targets. In glioblastoma and breast cancer cells, knockdown of miR-21 inhibited cell growth and induced apoptosis [50,83], suggesting that overexpression of miR-21 may promote tumor development via the negative regulation of proapoptotic factors. The oncogenic properties of miR-21 are mediated, at least in part, via its negative regulation of several important tumor suppressor genes. In addition, miR-21-mediated regulation of all three tumor suppressors is associated with increased invasion and metastasis, suggesting a role for miR-21 in cancer progression. The role of miR-21 in both the development and progression of cancer, in addition to the response to anticancer treatment, highlights the potential of miR-21 as a novel therapeutic target. The cluster is located on chromosome 13, at a region commonly amplied in a number of hematopoietic malignancies and solid tumors [93e95]. The oncogenic potential of miR-17-92 was rst highlighted in a mouse model of B-cell lymphoma . These tumors also demonstrated lower apoptosis, suggesting that the role of miR-17-92 in tumor development may be via antiapoptotic mechanisms. The negative regulation of the cell cycle regulator p21 by miR-17-92  may explain the effects of this polycistron on proliferation. Interestingly, miR-17-92 has been demonstrated to be directly induced by the oncogene c-myc , which is frequently up-regulated in cancer, further supporting an oncogenic role for miR-19-72. Surprisingly, loss of the genomic region encoding the miR-17-92 cluster has also been linked to malignancy in hepatocellular cancer . This potential tumor suppressor role of miR-17-92 may be explained by its negative regulation of the transcription factor E2F1 . E2F1 is induced by c-myc and promotes cell cycle progression , it also forms a positive feedback loop by inducing c-myc expression . Thus, the repression of E2F1 by miR-17-92 provides a mechanism for inhibition of c-myc-mediated growth. The down-regulation of miR- 17-92 in hepatocellular cancer may therefore provide a mechanism for tumor development. This suggests that miR-17-92 may have dual tumor suppressor and oncogenic roles in a tissue/ tumor-dependent manner. These include chromosomal alterations, dysregulated transcriptional activation, epigenetic modications, and alterations in biogenesis. The region encoding miR-15a and miR-16-1 is deleted in more than 50% of B-cell chronic lymphocytic leukemia cases . In contrast, the miR-17-92 cluster is encoded in an 800-bp region of the non-protein coding gene C13, which is frequently amplied in B-cell lymphoma and lung cancer [93,94]. Increased gene copy number has been demonstrated to correlate with overexpression of the cluster in both cancer types, supporting chromosomal amplications as a mechanism for dysregulation of miR-17-92. A t(8;17) translocation that juxtaposes the oncogene c-myc to chro- mosome 17 resulting in its overexpression, is associated with an aggressive form of B-cell leukemia . The underlying mechanism of c-myc up-regulation was unknown until it was demonstrated that this translocation positions c-myc at the promoter region of miR-142, which is encoded 50 nt from this chromosomal break . This suggests the involvement of miR-142 regulatory elements in the overexpression of c-myc. The transcription factor c-myc is involved in the regulation of approximately 15% of human genes, regulating cell death, proliferation, and differentiation  via both positive and negative regulation of gene expression. Co-expression of c-myc and the miR-17-92 polycistron accelerated oncogenesis in a murine model of B-cell lymphoma , supporting c-myc-mediated activation of miR-17-92 as a mechanism for tumorigenesis. Consequently, dysfunction of p53 is considered to be an early event in tumorigenesis. This is highlighted by the fact that p53 is mutated in over 50% of human cancers . Ectopic expression of all three miR-34 members has been demonstrated to have antiproliferative effects, inducing cell cycle arrest and apoptosis. Consistent with the tumor suppressor effects of miR-34 is the nding that miR-34 is down-regulated in a number of human cancers. Thus, p53-mediated activation of miR-34 provides a novel mechanism for tumor suppressor activity, and suggests that dysregulation of this pathway may provide a mechanism for oncogenic transformation.
