TL;DR: It is suggested that a novel LIM protein Cal induces cardiomyocyte differentiation through its dynamic intracellular shuttling and association with CSX/NKX2-5.
Abstract: The cardiac homeobox transcription factor CSX/NKX2-5 plays an important role in vertebrate heart development. Using a yeast two-hybrid screening, we identified a novel LIM domain–containing protein, named CSX-associated LIM protein (Cal), that interacts with CSX/NKX2-5. CSX/NKX2-5 and Cal associate with each other both in vivo and in vitro, and the LIM domains of Cal and the homeodomain of CSX/NKX2-5 were necessary for mutual binding. Cal itself possessed the transcription-promoting activity, and cotransfection of Cal enhanced CSX/NKX2-5–induced activation of atrial natriuretic peptide gene promoter. Cal contained a functional nuclear export signal and shuttled from the cytoplasm into the nucleus in response to calcium. Accumulation of Cal in the nucleus of P19CL6 cells promoted myocardial cell differentiation accompanied by increased expression levels of the target genes of CSX/NKX2-5. These results suggest that a novel LIM protein Cal induces cardiomyocyte differentiation through its dynamic intracellular shuttling and association with CSX/NKX2-5.

TL;DR: The results suggest the possibility that alcohol metabolism in individuals with the c2 gene may be greater than those with thec1 gene, and that the induction of CYP2E1 by ethanol in type B may occur more markedly than that in type A, although the sample number is too small to obtain final conclusions.
Abstract: Cytochrome P-450 (CYP) 2E1 is the major ethanol-oxidizing enzyme of the nonalcohol dehydrogenase metabolic pathway in the liver. Recently, the presence of genetic polymorphisms of this enzyme was confirmed. In this study, to clarify the influence of CYP2E1 genotype on alcohol metabolism, we analyzed acetaminophen metabolism in subjects with different CYP2E1 genotypes. In normal subjects, a half-life of acetaminophen from blood was the longest in type A (c1/c1) and was the shortest in type C (c2/c2). The elimination rate in type C was more than twice that of type A and type B (c1/c2). In type A, both half-life and elimination rate of acetaminophen were not different between patients with noncirrhotic alcoholic liver disease within 1 week after abstinence and in normal subjects. In one patient with minimal change, there were no differences in both half-life and elimination rate within 1 and 6 weeks after abstinence. On the other hand, in type B, half-life was shorter and the elimination rate was greater in alcoholic noncirrhotic patients within 1 week after abstinence than in alcoholic patients with type A and in normal subjects with type B. In type B, half-lives were shorter, and the elimination rates were greater in patients with alcoholic liver disease within 1 week after abstinence than 4 to 6 weeks after abstinence. These results suggest the possibility that alcohol metabolism in individuals with the c2 gene may be greater than those with the c1 gene, and that the induction of CYP2E1 by ethanol in type B may occur more markedly than that in type A, although the sample number is too small to obtain final conclusions.

TL;DR: It is suggested that continuous administration of AGEs-aptamer could protect against experimental diabetic nephropathy by blocking the A GEs-RAGE axis and may be a feasible and promising therapeutic strategy for the treatment of diabetic neephropathy.
Abstract: Advanced glycation end products (AGEs) and their receptor (RAGE) play a role in diabetic nephropathy. We screened DNA aptamer directed against AGEs (AGEs-aptamer) in vitro and examined its effects on renal injury in KKAy/Ta mice, an animal model of type 2 diabetes. Eight-week-old male KKAy/Ta or C57BL/6J mice received continuous intraperitoneal infusion of AGEs- or control-aptamer for 8 weeks. AGEs-aptamer was detected and its level was increased in the kidney for at least 7 days. The elimination half-lives of AGEs-aptamer in the kidney were about 7 days. Compared with those in C57BL/6J mice, glomerular AGEs levels were significantly increased in KKAy/Ta mice, which were blocked by AGEs-aptamer. Urinary albumin and 8-hydroxy-2′-deoxy-guanosine levels were increased, and glomerular hypertrophy and enhanced extracellular matrix accumulation were observed in KKAy/Ta mice, all of which were prevented by AGEs-aptamer. Moreover, AGEs-aptamer significantly reduced gene expression of RAGE, monocyte chemoattractant protein-1, connective tissue growth factor, and type IV collagen both in the kidney of KKAy/Ta mice and in AGE-exposed human cultured mesangial cells. Our present data suggest that continuous administration of AGEs-aptamer could protect against experimental diabetic nephropathy by blocking the AGEs-RAGE axis and may be a feasible and promising therapeutic strategy for the treatment of diabetic nephropathy.

TL;DR: This review summarizes the state-of-the-art knowledge on the molecular mechanisms that support pancreatic cancer EMT and the evidences that support its involvement in invasiveness/aggressiveness, and the drug resistance of pancreaticcancer cells.
Abstract: Epithelial to mesenchymal transition (EMT) is a physiologic process that allows morphological and genetic changes of carcinoma cells from an epithelial to a mesenchymal phenotype, which is the basis of the high metastatic potential of pancreatic cancer cells. EMT is triggered by various tumor microenvironmental factors, including cytokines, growth factors, and chemotherapeutic agents. This review summarizes the state-of-the-art knowledge on the molecular mechanisms that support pancreatic cancer EMT and the evidences that support its involvement in invasiveness/aggressiveness, and the drug resistance of pancreatic cancer cells.

TL;DR: Control of cell proliferation is important for cancer prevention since cell proliferation has essential roles in carcinogenesis including the process of initiation and promotion and availability of new biomarkers for cell proliferation, apoptosis or telomerase activity could be promising.
Abstract: Control of cell proliferation is important for cancer prevention since cell proliferation has essential roles in carcinogenesis including the process of initiation and promotion In rodent models for carcinogenesis, especially those for the carcinogenesis in digestive organs such as colon, liver or oral cavity, chemopreventive agents suppress carcinogen-induced hyperproliferation of cells in the target organs during the initiation as well as the postinitiation phases Therefore, effective agents usually suppress cell proliferation and inhibit the occurrence of malignant lesions Availability of new biomarkers for cell proliferation, apoptosis or telomerase activity could be promising By combining the use of intermediate biomarkers including premalignant lesions such as aberrant crypt foci in the colon or enzyme-altered foci in the liver and cell proliferation, short-term screening of effective chemopreventive agents will be possible
