  abstract  = {CXCR4 is a G-protein-coupled receptor that mediates recruitment of blood cells toward its ligand SDF-1. In cancer, high CXCR4 expression is frequently associated with tumor dissemination andpoor prognosis. We evaluated the novel CXCR4 probe [\(^{68}\)Ga]Pentixafor for invivo mapping of CXCR4 expression density in mice xenografted with human CXCR4-positive MM cell lines and patients with advanced MM by means of positron emission tomography (PET). [\(^{68}\)Ga]Pentixafor PET provided images with excellent specificity and contrast. In 10 of 14 patients with advanced MM [\(^{68}\)Ga]Pentixafor PET/CT scans revealed MM manifestations, whereas only nine of 14 standard [\(^{18}\)F]fluorodeoxyglucose PET/CT scans were rated visually positive. Assessment of blood counts and standard CD34\(^{+}\) flow cytometry did not reveal significant blood count changes associated with tracer application. Based on these highly encouraging data on clinical PET imaging of CXCR4 expression in a cohort of MM patients, we conclude that [\(^{68}\)Ga]Pentixafor PET opens a broad field for clinical investigations on CXCR4 expression and for CXCR4-directed therapeutic approaches in MM and other diseases.},

  abstract  = {Background Epigenetic modifications may play a relevant role in the pathogenesis of human abdominal aortic aneurysm (AAA). The aim of the study was therefore to investigate histone acetylation and expression of corresponding lysine [K] histone acetyltransferases (KATs) in AAA. Results A comparative study of AAA tissue samples (n = 37, open surgical intervention) and healthy aortae (n = 12, trauma surgery) was performed using quantitative PCR, immunohistochemistry (IHC), and Western blot. Expression of the KAT families GNAT (KAT2A, KAT2B), p300/CBP (KAT3A, KAT3B), and MYST (KAT5, KAT6A, KAT6B, KAT7, KAT8) was significantly higher in AAA than in controls (P ≤ 0.019). Highest expression was observed for KAT2B, KAT3A, KAT3B, and KAT6B (P ≤ 0.007). Expression of KAT2B significantly correlated with KAT3A, KAT3B, and KAT6B (r = 0.705, 0.564, and 0.528, respectively, P < 0.001), and KAT6B with KAT3A, KAT3B, and KAT6A (r = 0.407, 0.500, and 0.531, respectively, P < 0.05). Localization of highly expressed KAT2B, KAT3B, and KAT6B was further characterized by immunostaining. Significant correlations were observed between KAT2B with endothelial cells (ECs) (r = 0.486, P < 0.01), KAT3B with T cells and macrophages, (r = 0.421 and r = 0.351, respectively, P < 0.05), KAT6A with intramural ECs (r = 0.541, P < 0.001) and with a contractile phenotype of smooth muscle cells (SMCs) (r = 0.425, P < 0.01), and KAT6B with T cells (r = 0.553, P < 0.001). Furthermore, KAT2B was associated with AAA diameter (r = 0.382, P < 0.05), and KAT3B, KAT6A, and KAT6B correlated negatively with blood urea nitrogen (r = -0.403, -0.408, -0.478, P < 0.05). In addtion, acetylation of the histone substrates H3K9, H3K18 and H3K14 was increased in AAA compared to control aortae. Conclusions Our results demonstrate that aberrant epigenetic modifications such as changes in the expression of KATs and acetylation of corresponding histones are present in AAA. These findings may provide new insight in the pathomechanism of AAA.},
