[Q]: Abstract: The decline in immunocompetence with age is accompanied by the increase in the incidence of autoimmune diseases. Aging of the immune system, or immunosenescence, is characterized by a decline of both T and B cell function, and paradoxically the presence of low-grade chronic inflammation. There is growing evidence that epigenetics, the study of inherited changes in gene expression that are not encoded by the DNA sequence itself, changes with aging. Interestingly, emerging evidence suggests a key role for epigenetics in human pathologies, including inflammatory and neoplastic disorders. Here, we will review the potential mechanisms that contribute to the increase in autoimmune responses in aging. In particular, we will discuss how epigenetic alterations, especially DNA methylation and histone acetylation, are accumulated during aging and how these events contribute to autoimmunity risk..

[Q]: Abstract: How oncogenic signalling coordinates glycolysis and anabolic biosynthesis in cancer cells remains unclear. We recently reported that the glycolytic enzyme phosphoglycerate mutase 1 (PGAM1) regulates anabolic biosynthesis by controlling intracellular levels of its substrate 3-phosphoglycerate and product 2-phosphoglycerate. Here we report a novel mechanism in which Y26 phosphorylation enhances PGAM1 activation through release of inhibitory E19 that blocks the active site, stabilising cofactor 2,3-bisphosphoglycerate binding and H11 phosphorylation. We also report the crystal structure of H11-phosphorylated PGAM1 and find that phospho-H11 activates PGAM1 at least in part by promoting substrate 3-phosphoglycerate binding. Moreover, Y26 phosphorylation of PGAM1 is common in human cancer cells and contributes to regulation of 3-phosphoglycerate and 2-phosphoglycerate levels, promoting cancer cell proliferation and tumour growth. As PGAM1 is a negative transcriptional target of TP53, and is therefore commonly upregulated in human cancers, these findings suggest that Y26 phosphorylation represents an additional acute mechanism underlying phosphoglycerate mutase 1 upregulation..

[Q]: Abstract: The Constant-Murley shoulder assessment score has proven to be a valuable diagnostic instrument. Thus, in the literature it has been mentioned that the clinical accuracy of this score varies especially when comparing patients in larger, inhomogeneous patient groups. The "relative Constant score" (CS(rel)) tries to minimize these problems by using reference parameters out of healthy age and gender related control groups. The authors of this study tried to show that it is even more accurate to use the functional performance of the uninjured collateral shoulder of the same individual as reference, introducing the "individual relative Constant score" (CS(indiv)). The CS(indiv) and the CS(rel) were compared for 125 consecutive patients with shoulder disorders, and a group of 125 healthy volunteers as a control group. In a non-parametric comparison of the reciever operating characteristics the CS(indiv) shows the higher ability to discriminate between patients and healthy volunteers (p=0.004). This indicates that the individual relative Constant score gives a more accurate view about the functional result for shoulder disorders. It is expected to be more reliable for larger and incoherent patient populations, because specific interindividual differences, regarding the patient's age, gender and constitution are eliminated as well as other individual physiological parameters..
