Long noncoding RNA cell as a molecular biomarker in glioma

A novel coumarin-thiourea conjugate was synthesized facilely. It served as a fluorescent turn-on chemosensor for selective detection of Hg2+ ion over other common competitive metal ions including Li+, Na+, K+, Ag+, Cu2+, Fe2+, Zn2+, Co2+, Ni2+, Mn2+, Sr2+, Ca2+, Mg2+, Al3+, Cr3+ and Fe3+ ions based on the Hg2+-promoted desulfurization and cyclization reactions. Addition of Hg2+ ion to the sensor solution in 28 EtOH/H2O induced a hypsochromic shift of the UV-Vis absorption band from 360 nm to 340 nm accompanying distinct enhancement in the absorption intensity while addition of other metal ions failed to bring about substantial change in the absorption spectra. Addition of Hg2+ to the sensor solution also caused marked increase in the fluorescence emission intensity and most common competitive metal ions did not interfere with the selective sensing of Hg2+ ion by the sensor. The detection limit of Hg2+ ion by the probe was calculated to be 1.46 × 10-7 M and the probe could be utilized for selective detection of Hg2+ ion by fluorescence turn-on mode over a broad pH range of 1-11.Neuroblastoma (NB) is the common pediatric tumor of the sympathetic nervous system characterized by poor prognosis. Owing to the challenges such as high tumor heterogeneity, multidrug resistance, minimal residual disease, etc., there is an immediate need for exploring new therapeutic strategies and effective treatments for NB. Herein, in the current study, we explored the unexplored response of NB cells to the second-generation histone deacetylase inhibitor (HDACi) JNJ-26481585(JNJ) and the lysosomotropic agent, Chloroquine (CQ) alone and upon JNJ/CQ treatment as a plausible therapeutic. We identify that while JNJ alone induced autophagy in NB cells, JNJ/CQ treatment decreased the viability and proliferation of NB cells in vitro by switching from autophagy to apoptosis. Further we found that autophagy inhibition by CQ pre-treatment led to the generation of ROS and a decrease in the mitochondrial membrane potential (MMP) that subsequently caused caspase-3-mediated apoptotic cell death in NB cells. Corroborating the above observations, we found that the ROS scavenger N-acetylcysteine (NAC) countered caspase-3 activity and the cells were rescued from apoptosis. Finally, these observations establish that JNJ/CQ treatment resulted in cell death in NB cells by triggering the formation of ROS and disruption of MMP, suggesting that modulation of JNJ-induced autophagy by CQ represents a promising new therapeutic approach in NB.Dopamine (DA) is critical for motivation, reward, movement initiation, and learning. Mechanisms that control DA signaling have a profound impact on these important behaviors, and additionally play a role in DA-related neuropathologies. The presynaptic SLC6 DA transporter (DAT) limits extracellular DA levels by clearing released DA, and is potently inhibited by addictive and therapeutic psychostimulants. Decades of evidence support that the DAT is subject to acute regulation by a number of signaling pathways, and that endocytic trafficking strongly regulates DAT availability and function. Barasertib DAT trafficking studies have been performed in a variety of model systems, including both in vitro and ex vivo preparations. In this review, we focus on the breadth of DAT trafficking studies, with specific attention to, and comparison of, how context may influence DAT's response to different stimuli. In particular, this overview highlights that stimulated DAT trafficking not only differs between in vitro and ex vivo environments, but also is influenced by both sex and anatomical subregions.BACKGROUND Despite recent advances in immunosuppressive therapy for patients with primary nephrotic syndrome, its effectiveness and safety have not been fully studied in recent nationwide real-world clinical data in Japan. METHODS A 5-year cohort study, the Japan Nephrotic Syndrome Cohort Study, enrolled 374 patients with primary nephrotic syndrome in 55 hospitals in Japan, including 155, 148, 38, and 33 patients with minimal change disease (MCD), membranous nephropathy (MN), focal segmental glomerulosclerosis (FSGS), and other glomerulonephritides, respectively. The incidence rates of remission and relapse of proteinuria, 50% and 100% increases in serum creatinine, end-stage kidney disease (ESKD), all-cause mortality, and other major adverse outcomes were compared among glomerulonephritides using the Log-rank test. Incidence of hospitalization for infection, the most common cause of mortality, was compared using a multivariable-adjusted Cox proportional hazard model. RESULTS Immunosuppressive therapy was administered in 339 (90.6%) patients. The cumulative probabilities of complete remission within 3 years of the baseline visit was ≥ 0.75 in patients with MCD, MN, and FSGS (0.95, 0.77, and 0.79, respectively). Diabetes was the most common adverse events associated with immunosuppressive therapy (incidence rate, 71.0 per 1000 person-years). All-cause mortality (15.6 per 1000 person-years), mainly infection-related mortality (47.8%), was more common than ESKD (8.9 per 1000 person-years), especially in patients with MCD and MN. MCD was significantly associated with hospitalization for infection than MN. CONCLUSIONS Patients with MCD and MN had a higher mortality, especially infection-related mortality, than ESKD. Nephrologists should pay more attention to infections in patients with primary nephrotic syndrome.Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract; most of them have gain-of-function mutations of the KIT gene. There have been rare cases of families with multiple GISTs, that had autosomal dominant germline KIT mutations. Here, we present a case of multiple GISTs caused by a novel germline KIT mutation. Intraoperatively, the main tumor was present in the body of the stomach, and multiple small nodules were detected mainly in the upper and middle part of the gastric wall; several nodules were also present in the small bowel wall. The main tumor and surrounding nodules were resected. DNA sequencing of the tumor tissue, adjacent normal mucosal tissue, and peripheral blood leukocytes revealed that the patient had germline Asp820Gly mutation in exon 17 of the KIT gene. This is the first case with germline Asp820Gly mutation in exon 17 of the KIT gene.
