Background Arginases (ARG isoforms, ARG-1/ARG-2) are key regulatory enzymes of inflammation and tissue repair; however, their role after neonatal brain hypoxia (H) and hypoxia-ischemia (HI) remains unknown. Methods C57BL/6 mice subjected to the Vannucci procedure on postnatal day (P9) were sacrificed at different timepoints. The degree of brain damage was assessed histologically. ARG spatiotemporal localization was determined via immunohistochemistry. ARG expression was measured by Western blot and activity spectrophotometrically. Results ARG isoform expression increased during neurodevelopment (P9-P17) in the cortex and hippocampus. This was suppressed with H and HI only in the hippocampus. In the cortex, both isoforms increased with H alone and only ARG-2 increased with HI at 3 days. ARG activity during neurodevelopment remained unchanged, but increased at 1 day with H and not HI. ARG-1 localized with microglia at the injury site as early as 4 h after injury, while ARG-2 localized with neurons. Conclusions lization and expression of ARGs in brain during development and after stroke.Background Small-for-gestational-age (SGA) neonates are at a higher risk of adult-onset metabolic disorders because of fetal programming in the presence of growth restriction. Nephrogenesis may also be affected in fetal growth restriction. This study hypothesized that urinary podocalyxin levels, a marker of nephrogenesis, would be lower among preterm SGA neonates as compared to appropriate-for-gestational-age (AGA) controls. Methods This cross-sectional study enrolled gestation-matched SGA (n = 90) and AGA (n = 45) neonates born at 260-366 weeks of gestation. The SGA group comprised of 45 neonates with birth weight between 3rd and 10th centile and 45 neonates with birth weight less then 3rd centile. The primary outcome of the study was the difference in urinary podocalyxin levels between SGA and AGA neonates. Glomerular and tubular functions were also assessed. Results Urinary podocalyxin levels were similar in SGA and AGA neonates (ng/mg of creatinine; median [interquartile range] 28.7 [4.8-70.2] vs. 18.7 [3.1-55.9]), P value 0.14). No correlation was observed between birth weight centile and urinary podocalyxin levels (r -0.06). Glomerular filtration rate, fractional excretion of sodium, and serum β-2-microglobulin levels were comparable across the study groups. Conclusions Glomerular development as assessed by urinary podocalyxin levels and renal functions are comparable in SGA and AGA preterm neonates. Impact Neonates born with fetal growth restriction are at a higher risk of adult-onset metabolic disorders because of fetal programming.This cross-sectional study investigated the effect of presence and severity of fetal growth restriction on glomerular development by measuring urinary podocalyxin levels in preterm infants.This study did not observe any effect of the presence or severity of fetal growth restriction on urinary podocalyxin levels and other markers of glomerular and renal tubular functions.BACKGROUND Growing evidence indicates an association between microfibril-associated protein 2 (MFAP2) and a number of physiological and pathological mechanisms. The potential role of MFAP2 in cancer requires further elucidation. The present study investigated the biological behavior of MFAP2 in melanoma patients.  https://www.selleckchem.com/products/caspofungin-acetate.html  MATERIAL AND METHODS MFAP2 inhibition was established in the B16 melanoma cell line through the use of RNA interference and was assessed by quantitative real-time PCR (qRT-PCR) and Western blot analysis. Wound-healing analysis, transwell assay, and in vivo imaging were performed to investigate the roles of MFAP2 reducing cell mobility, migration, and invasion abilities in vitro and in vivo. RESULTS We found substantially higher MFAP2 expression in B16 melanoma cells. The knockdown of MFAP2 inhibited B16 melanoma cells migration and invasion. Western blot analysis was used to assess changes in biomarkers of EMT, indicating the function of MFAP2 in EMT. We found that downregulation of MFAP2 altered the expression of Wnt/ß-catenin-linked protein. CONCLUSIONS Our results suggest that MFAP2 has potential as a molecular target to treat melanoma and suppress metastasis of melanoma cells.Objectives Currently, combination therapy of ramucirumab (RAM) + docetaxel (DOC) must play a more important role as a second-line treatment. Epithelial growth factor receptor (EGFR) mutation accounts for around 50% of oncogenic driver mutations in patients with advanced non-small cell lung cancer (NSCLC) in Asian subsets. The number of brain metastases (BM) is relatively higher in EGFR mutation-positive patients compared to EGFR wild-type patients. The objective of this study is to evaluate the efficacy of RAM + DOC focusing on EGFR mutation and BM. Methods We retrospectively reviewed consecutive advanced NSCLC patients who received combination therapy of RAM + DOC at three institutions. A total of 112 patients with NSCLC were enrolled for efficacy analyses. We evaluated the efficacy of RAM + DOC for EGFR-mutated NSCLC with endpoints including progression-free survival (PFS), time to treatment failure (TTF) and overall survival. Results Median PFS was 5.7 months for the EGFR mutant group compared with 3.6 months for the EGFR wild-type group (HR 0.53, 95% CI 0.32-0.87; p = 0.01). Median TTF was 5.1 months for the EGFR mutant group compared with 2.8 months for the EGFR wild-type group (HR 0.53, 95% CI 0.33-0.85; p = 0.007). Median PFS and TTF of the EGFR mutant group was significantly longer than median PFS and TTF of the EGFR wild-type group. The multivariate analysis identified EGFR mutation status as an independent favorable factor of PFS. In subset analyses of BM, median PFS of the EGFR mutant group (2.8 months) was significantly shorter than that of the EGFR wild-type group (5.1 months) (HR 7.27, 95% CI 1.78-29.68; p = 0.002). Conclusion This study revealed that EGFR mutation status and BM might be predictive or prognostic factors for PFS.Human mesenchymal stem cells (MSCs), a promising source of stem cells for regenerative medicine, have different morphological and functional characteristics. Carbohydrate moieties on the cell surface play an important role, including cell-cell interaction and cell recognition. The objective of this study was to determine possible differences in glycoconjugate distribution patterns of MSCs derived from various sources. MSCs were isolated from adipose tissue, bone marrow, Wharton's jelly, and cord blood. Then, they were stained with FITC-conjugated wheat germ agglutinin (WGA), peanut agglutinin (PNA), concanavalin A (ConA), Ulex europaeus (UEA), Dolichos biflorus (DBA), and Atto-488 conjugated Phytolacca americana (PWM) lectins. The intensity of the reactions was scored using ImageJ software. Flow cytometry was performed to detect the expression of the endothelial marker CD144. The obtained data were analyzed by ANOVA and LSD. Cord blood-derived MSCs showed the most significant staining intensities with all lectins.
