Another concern 26 for excessive use of omega-3 fatty acids is their susceptibility to oxidation. The Mediterranean diet comprising mostly of oleic 02 acid rich olive oil appear to provide high protection against cognitive decline as 03 observed for the aged population in Southern Italy (Solfrizzi et al. No other differences in the fatty acid composition of the different 31 phospholipids fractions were noted in this study. A relatively small 40 pilot study with 10 elderly subjects (average age 83 yrs) suffering from senile 41 dementia of cerebrovascular disorders has been performed (Terano et al. However, there cannot 05 be any compromise with the oxidative quality of the omega-3 supplements and the 06 freshness of the fish, as discussed below. Exposure to air, heat and light causes the unsaturated moieties of the 13 fatty acids to undergo a spontaneous free radical-initiated chemical reaction called 14 autoxidation. After the end of the induction period, oxidative 17 deterioration of the lipids occurs much more quickly. It is well known that the 18 greater the number of unsaturated sites, the greater is the tendency of oxidation. For 19 example, if the rate of oxidation for oleic acid (18:1) is 1, then the relative rates of 20 oxidation for linoleic acid and alpha-linolenic acid are 12 and 25 respectively. These oxidation products are 26 a potential source of free radicals which may cause damaging effects in vivo. However, use of antioxidants after the end of this period is 32 generally ineffective because by that time, the oil or fat has developed considerable 33 degree of rancidity. Storage of oils and fats in closed containers and in cool, dark 34 places away from heat sources also prolongs the induction period. The major synthetic antioxidants 36 which are widely used in various food products are t-butylhydroquinone, butylated 37 hydroxy toluene, butylated hydroxy anisole and propyl gallate. However, possible 38 harmful side effects of the synthetic antioxidants have created a demand for natural 39 antioxidants. Several 02 beneficial properties have been attributed to these dietary compounds, including 03 anti-inflammatory and anticarcinogenic effects (Galati and OBrien, 2004). Though 04 these natural phenolics/flavonoids are generally regarded safe, controlled clinical 05 trials to show efficacy and potential for toxicity of many of these natural antioxi- 06 dants are still required. These natural compounds are generally lipophilic and dietary 07 lipids can act as the carrier of such active ingredients which would provide multiple 08 benefits. It is never too late to initiate and benefit from the nutritive 14 effects of dietary lipids. When designed with healthy and top quality oils, the 16 innumerable varieties of prepared foods available can play an important role in the 17 diet schemes. However, dietary fats have to be consumed with prudence and in 18 moderate amounts. Nordic Nutrition Recommendations suggests a limitation of the 19 intake of saturated plus trans fatty acids to about 10% of the total energy intake (E%), 20 and of the total fat intake to 30E%. In my effort to elucidate the neuroprotec tive mechanism (s) associated with these changes in metabolite availability, I start ed investigating the complex alterations occurring in multiple integrated neural a nd metabolic processes.

Hippocrates later suggested that epilepsy could be a hereditary disease and not connected to witchcraft. Epilepsy is a disabling chronic and socially isolating neurological disorder involving recurrent abnormal discharges of neurons that produce epileptic seizures (Engel and Pedley, 1997; Johnston and Smith, 2008). Genetic heterogeneity, variable age of onset, and multifactorial inheritance has hindered progress in identifying the genetic and biochemical components responsible for the most common forms of human idiopathic generalized epilepsies (Tan et al. While some idiopathic epilepsies are inherited as simple Mendelian traits, most are multifactorial where more than one gene together with environmental factors contribute to the disease phenotype (Berkovic, 1998; Todorova et al. In contrast to idiopathic epilepsy, symptomatic or acquired epilepsy often accompanies brain trauma, injury, or neurostructural defects. Generalized seizures tend to involve both cerebral hemispheres, whereas partial (also called local or focal) seizures are localized in one cerebral hemisphere (Hauser, 1982; Hauser, 1992). Natural occurring models of epilepsy are especially important, since many of the non-natural models (e. Epidemiological data indicate that 20-40% of the patients with newly diagnosed epilepsy will become refractory to treatment, due to both environmental (e.

Metastasis buy anastrozole 1 mg free shipping zoloft menstrual cycle, the process by which cancer cells disseminate from the primary tumor site and establish secondary tumors at distant sites buy anastrozole 1 mg visa grants for women's health issues, is the predominant cause of cancer-related deaths purchase generic anastrozole on line womens health group manhattan ks. Overexpression of miR-10b increases cell motility and invasiveness, effects that are reversed upon inhibition of expression, both in vitro [65] and in vivo [66], 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 [59]. In colorectal cancer, miR-21 expression is associated with tumor stage, invasion, and prognosis [69]. Whilst in lung cancer, reduced let-7 was indicative of a poor prognosis in two independent studies [62,70]. In prostate cancer [74], 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 [70], 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 [4], thyroid [75], and prostate [76] 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 [94]. 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 [98] 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 [99], 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 [100]. This potential tumor suppressor role of miR-17-92 may be explained by its negative regulation of the transcription factor E2F1 [99]. E2F1 is induced by c-myc and promotes cell cycle progression [101], it also forms a positive feedback loop by inducing c-myc expression [102]. 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 [54]. 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 [105]. 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 [6]. 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 [108] 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 [94], 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 [112]. 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. Methylation of CpG islands, which are associated with the promoter regions of genes, results in transcriptional silencing. Conversely, a reduction in global methylation levels (hypo- methylation) is also associated with cancer. Consequently, alterations in histone modication patterns, often in combination with dysregulated hypermethylation, are commonly demonstrated in carcinogenesis. Interestingly, both methylation and histone deacteylation were demonstrated to be involved in transcriptional repression of miR- 127, as induction of expression was only evident following both demethylating and deace- tylase inhibition treatment. Conversely, reduced expression of Dicer was demonstrated in a subset of non-small-cell lung cancers with a poor prognosis [130]. This down-regulation was signicantly associated with the reduced expression of let-7, suggesting altered processing as a mechanism for let-7 dysregulation. Interestingly, the downregulation of Dicer was not due to methylation of the promoter, suggesting alternative mechanisms of dysregulation. This was also supported in ovarian cancer where reduced expression of Dicer was associated with advanced tumor stage [131].
