Background Penfluridol, a commonly used antipsychotic agent in a clinical setting, exhibits potential anti-cancer properties against various human malignancies. Here, we investigated the effect of penfluridol on the biological behavior of CRC cells. Methods Cell viability and clonogenic potential were detected by the cell counting kit-8 and colony formation assay. The cell apoptosis and cell cycle distribution were quantified through flow cytometry. Caspase-3 activity, glucose consumption, lactate production, and intracellular ATP levels were evaluated using the corresponding commercial detection kits. The protein levels of related genes were detected through Western blotting. Mitochondrial membrane potential was detected using JC-1 staining. A CRC xenograft tumor model was used to validate the anti-tumor activity of penfluridol in vivo. buy S64315 Results Penfluridol reduced cell survival and promoted apoptotic cell death effectively through the mitochondria-mediated intrinsic pathway in a dose-dependent manner. Further, the process of glycolysis in HCT-116 and HT-29 cells were inhibited upon penfluridol treatment, as evidenced by the decrease in glucose consumption, lactate production, and intracellular ATP levels. Further mechanistic studies revealed that penfluridol influenced cell apoptosis and glycolysis in CRC cells by down-regulating hexokinase-2 (HK-2). The pro-apoptotic effect and glycolytic inhibition-induced by penfluridol were effectively reversed by HK-2 overexpression. Consistent with in vitro results, penfluridol could also suppress tumor growth and trigger apoptosis in vivo. Conclusion Penfluridol triggers mitochondrial-mediated apoptosis and induces glycolysis inhibition via modulating HK-2 in CRC and provides a theoretical basis to support penfluridol as a repurposed drug for CRC patients.I thank Lindahl and Li for their thoughtful comments on the non‐anticoagulant properties of heparin.1 Heightened awareness of hypercoagulability has made heparin part and parcel of the COVID‐19 management algorithms. In addition, reports of prophylactic anticoagulation failure have triggered several trials where escalated doses of heparin are compared with standard doses with the aim of preventing thrombotic complications. At this juncture, we do need to consider where do the non‐anticoagulant properties of heparin fit in the COVID‐19 clinical context?Background The NIH protocol for nonmyeloablative (NMA) conditioning allogeneic stem cell transplantation (alloSCT) with alemtuzumab and low-dose total body irradiation corrected the abnormal sickle cell disease (SCD) phenotype without the risk of graft-versus-host disease. AlloSCT using NMA conditioning had been rarely applied to β-thalassemia major (β-TM) patients. Methods To avoid prolonged immunosuppression, we developed a two-stage strategy. Mixed donor chimerism was initially achieved using the protocol developed by the NIH. Thereafter, we facilitated donor chimerism using the optional reinforced stem cell (SC) infusion in cases requiring protracted immuno-suppression or experiencing impeding graft failure. Results In this study, β-TM (n=9) and SCD (n=4) patients were equally effectively treated with eradicating the abnormal hemoglobin phenotype. Five patients, including four β-TM, achieved stable mixed chimerism without receiving optional reinforced SC infusion. All patients that received optional reinforced infusion recipients achieved complete (n=4) or mixed chimerism (n=1). The overall survival rate and event-free survival at 4 years of 91.7% (95% CI; 53.9-98.8) in both groups, with a thalassemia-free survival rate in β-TM patients of 87.5% (95% CI; 38.7-98.1). Conclusion This study is the first to report successful NMA conditioning alloSCT to achieve stable mixed chimerism correcting the abnormal hemoglobin phenotype in adult β-TM patients.Several papers have described hyponatraemia with tramadol. However, in most reports, several confounding factors can be found. We used the WHO pharmacovigilance database (VigiBase®) to investigate if tramadol alone could be associated with hyponatraemia. All 1992-2019 ICSRs (individual case safety reports) with the preferred term (PT) "hyponatraemia" and tramadol were included. Two disproportionality analyses were performed (1) after inclusion of all reports, and (2) after exclusion of concomitant hyponatraemic drugs. Results are expressed as reporting odds ratios (ROR; 95% CI) and information component (IC). Of 19 747 604 ICSRs, 225 575 were included. A significant association was found between tramadol use and reports of hyponatraemia (ROR = 1.49 [1.39-1.60], IC = 0.57 [IC025 = 0.47]). After exclusion of hyponatraemic drugs, the previously found association disappeared. The study failed to find any pharmacovigilance signal of hyponatraemia with tramadol alone. We suggest that reports of hyponatraemia with tramadol can be explained principally by other underlying causes of hyponatraemia, especially other concomitant hyponatraemic drugs.Although mesenchymal stem/stromal cells (MSCs) are being explored in numerous clinical trials as proangiogenic and proregenerative agents, the influence of tissue origin on the therapeutic qualities of these cells is poorly understood. Complicating the functional comparison of different types of MSCs are the confounding effects of donor age, genetic background, and health status of the donor. Leveraging a clinical setting where MSCs can be simultaneously isolated from discarded but healthy bone and thymus tissues from the same neonatal patients, thereby controlling for these confounding factors, we performed an in vitro and in vivo paired comparison of these cells. We found that both neonatal thymus (nt)MSCs and neonatal bone (nb)MSCs expressed different pericytic surface marker profiles. Further, ntMSCs were more potent in promoting angiogenesis in vitro and in vivo and they were also more motile and efficient at invading ECM in vitro. These functional differences were in part mediated by an increased ntMSC expression of SLIT3, a factor known to activate endothelial cells. Further, we discovered that SLIT3 stimulated MSC motility and fibrin gel invasion via ROBO1 in an autocrine fashion. Consistent with our findings in human MSCs, we found that SLIT3 and ROBO1 were expressed in the perivascular cells of the neonatal murine thymus gland and that global SLIT3 or ROBO1 deficiency resulted in decreased neonatal murine thymus gland vascular density. In conclusion, ntMSCs possess increased proangiogenic and invasive behaviors, which are in part mediated by the paracrine and autocrine effects of SLIT3.
