The proposed criteria are based on the accumulating evidence stating that autoimmunity has a key role in some patients and, presumably, a different clinical entity. Diagnosis requires establishing the autoimmune basis of the disease following an echocardiographic diagnosis. Cell mediated autoimmune response is may be generalized, or affect solely the left ventricle. Several predisposing conditions may coexist, along with immune abnormalities and autoantibodies that play a key role in the pathogenesis (5, 6). Autoimmunity may be Pathogenesis triggered by various exogenous factors in predisposed indi- viduals (6). Preliminary signs and symptoms mitochondrial translocator protein have been shown to usually begin between ages 2050 years, although people cause cell lysis in rats (6). Mortality rate is as high as 1550% in 5 years, mostly because of ventricular arrhyth- mias and heart failure (7). Diagnostic Criteria The most practical diagnostic procedure is echocardiogra- phy, although radionuclide scanning or angiography Laboratory Findings might be used as well in attempt to confirm diagnosis (7).

Since these genes are involved in de novo as well as maintenance methylation cheap aurogra 100mg on-line, their aberrant expression suggests that aberrant methylation may be widespread in endometriosis. Further study by the same group found that a stretch of CpG demethylation within a non-promoter CpG island of the aromatase gene in endometriotic cells while the same region is heavily methylated and associated with methyl- CpG-binding proteins in endometrial cells [93]. Endometriotic cells are found to lack the intercellular adhesion protein E-cadherin, a known metastasis-suppressor protein in epithelial tumor cells whose deregulation also seems to be associated with invasiveness of endometriotic cells [94,95]. This seems to suggest that, at least in endometriotic cell lines, E-cadherin silenced by methyl- ation is associated with invasiveness. There are 11 hypermethylated and nine hypomethylated chromosomal regions common to all three subtypes of endometriosis. Hypermethylated regions appear to be located at the ends of chromosomes, while hypomethylated regions are found to be randomly distributed along the chromosomes [98]. While this high-thoughput technology can identify many aberrant methylations in a single study, caution should be made. First, not all aberrant methylations are associated with aberrant gene expression, as evidenced by the poor correlation coefcient between the gene expression induction ratio and methylation ratio (r 0. In fact, among 20 transcription factors for which expression data were also available, the agreement between expression levels (in direction and in terms of statistical signicance) and methylation patterns is merely 20% (or four out of 20). Second, while the use of paired eutopic and ectopic endometrium can effectively minimize the between-individual variation and reveal difference between the two tissues, the study design cannot detect aberrant methylations that are shared by the two tissues. The H3 and H4 histones, in particular, have long tails protruding from the nucleosome and can be covalently modied post-translationally at various residuals and in various ways. Thus, the combinations of modications are proposed to constitute a code for gene expression, the so-called histone code [100,101]. For ease of exposition, we shall review published work, albeit few, in writers and erasers of histone acetylation and methylation. Acetylated histones are generally associated with euchromatin and transcriptional activation. Hisone lysines can be methyl- ated in different forms: mono- (me1), di- (me2), or trimethylated (me3). Histone arginine methylation can be monomethylated, symmetrically or asymmetrically dimethylated. While histone methylation has been known since the early 1960s, it was generally thought that histone methylation, unlike acetylation and phorsphorylation, was biochemically stable and irreversible. Histone acetylation, methylation, and phosphorylation are the most investigated histone modications. By recruiting these reader/ effector proteins, histone modications lead to changes in chromatin structure as well as dynamics [111]. As at time of writing, there has been no published account on aberration of any reader/effector modules in histone modications. Given the reported epigenetic aberrations in endometriosis, one question is whether these aberrations are the cause or merely the consequence of endometriosis. In a linearly causal relationship, the cause and consequence can be clearly dened, with temporal sequences, and necessary and sufcient cause distinguished. In many ways, a complex transcription network often has a highly optimized tolerance featuring high efciency, performance, and robustness to designed-for-uncertainties yet hypersensitive to design aws and unanticipated perturbations [114]. In such a system, the demarcation of cause and consequence could be difcult since the removal of one part may affect other parts of the system, especially when the system is redundant. Therefore, it may be difcult to prove that in endometriosis aberrant methylation is a cause rather than a consequence. Despite this challenge, it is known that methylation can be induced by various factors. This provides evidence that certain phenotypic changes in endometriosis, such as increased production of proin- ammatory cytokines, may also cause epigenetic aberrations, which in turn result in changes in gene expression and subsequently other phenotypic changes such as increased cellular 454 proliferation [126] and perhaps some phenotypic changes. Remarkably, developmental exposures to chemicals can also result in aberrant methylation. Nevertheless, the developmental origins of many chronic diseases such as type 2 diabetes have now been demonstrated epidemiologically [134]. Further research in this area is sorely needed, not just for the sake of understanding of endometriosis pathogenesis but also because proper nutritional intervention may reverse the aberrant epigenetic changes [136,137]. Hence, enzymes that regulate the epigenetic changes could be ideal targets for intervention by pharmacological means. Given the accumulating evidence that endometriosis may be an epigenetic disease, naturally one may wonder as to whether endo- metriosis can be treated by correcting epigenetic aberrations through pharmacological means. It has been shown that women with endometriosis have aberrant uterine contractility during menses with increased frequency, amplitude, and basal pressure tone as compared with those without [159]. There is a sign that in the uterus of women with dysmenorrhea there is a lack of synchronization in fundal-cervical contraction [160]. Incidentally, progesterone, a traditional drug for treating endometriosis-associated dysmenorrhea, can also inhibit myometrial contraction [161]. After all, endometriosis is not a fatal disease even if left untreated, hence the demand for better safety and side effect proles is higher than anticancer drugs [35].
