Sorafenib (SOR) resistance remains a major obstacle in the effective treatment of hepatocellular carcinoma (HCC). A number of long noncoding RNAs (lncRNAs) are responsible for this chemoresistance. This study aimed to reveal the essential function of a recently defined lncRNA, lncRNA-POIR, in the epithelial-mesenchymal transition (EMT) and SOR sensitivity of HCC cells. SOR-induced cytotoxicity was analyzed via cell counting kit-8 and ethynyl-2'-deoxyuridine incorporation assays, whereas immunoblotting and confocal immunofluorescence were used to determine the expression levels of EMT markers. Furthermore, loss- or gain-of-function approaches were used to demonstrate the role of lncRNA-POIR/miR-182-5p on EMT and SOR sensitivity in HCC. AZ191 The direct interaction between lncRNA-POIR and miR-182-5p was verified using a luciferase reporter assay. We found that knockdown of lncRNA-POIR sensitized HCC cells to SOR and simultaneously reversed EMT. As expected, miR-182-5p was confirmed as the downstream target of lncRNA-POIR. Moreover, miR-182-5p overexpression clearly reversed EMT and promoted SOR-induced cytotoxicity in representative HCC cells, whereas miR-182-5p downregulation played a contrasting role; miR-182-5p knockdown abolished the modulatory effects of lncRNA-POIR siRNA on EMT and SOR sensitivity. Together, these pieces of data suggest that lncRNA-POIR promotes EMT progression and suppresses SOR sensitivity simultaneously by sponging miR-182-5p. Thus, we proposed a compelling rationale for the use of lncRNA-POIR as a promising predictor of SOR response and as a potential therapeutic target for HCC treatment in the future.Resistant hypertension was defined according to the 2008 scientific statement as office blood pressure ≥ 140/90 mm Hg and the 2018 scientific statement as office blood pressure ≥ 130/80 mm Hg. We investigated the prognostic significance of lowered blood pressure threshold for defining resistant hypertension in the 2018 American Heart Association scientific statement compared with that in the 2008 scientific statement. The participants of this prospective cohort were enrolled from December 2013 to November 2018. Major adverse cardiovascular events (MACEs) were defined as a composite of cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, and heart failure hospitalization. Renal event was defined as a ≥ 50% decline in estimated glomerular filtration rate or progression to end-stage renal disease. A total of 206 patients among 2018 (10.2%) were diagnosed with resistant hypertension by the previous definition (≥140/90 mm Hg), and 276 patients among 2011 (13.7%) were diagnosed with resistant hypertension by the updated definition (≥130/80 mm Hg). During a median follow-up of 4.5 years, 33 MACEs (3.7 per 1000 patient-years) and 164 renal events (19.9 per 1000 patient-years) occurred in the study population. Treatment-resistant hypertension groups had a higher incidence rate of MACEs and renal events than the control groups. In multivariate Cox proportional hazards regression analysis, resistant hypertension by both definitions was significantly associated with increased risk of MACE and renal event. Both the previous and updated definitions of resistant hypertension were significant predictors of MACEs and renal events. This finding supports the adoption of the updated criteria for resistant hypertension in clinical practice.We investigated if the dual systems model could explain the increased rates of substance use among at-risk youth. This study sampled 365 adolescents, 289 of which had a family history of substance use disorder, assessed biannually between the ages 13-16 years old. Growth curve analyses revealed that higher levels of impulsivity were related to higher levels of sensation seeking and a slower rate of decline in impulsivity was related to a faster rate of increase in sensation seeking. Only family history status and sensation seeking were directly associated with substance use (marijuana, alcohol) at age 16, though family history status was also indirectly related to substance use through higher levels of impulsivity to higher levels of sensation seeking.The transcription factor TBX1 is the major gene implicated in 22q11.2 deletion syndrome (22q11.2DS). The complex clinical phenotype includes vascular anomalies and a recent report presented new cases of primary lymphedema in 22q11.2DS patients. We have previously shown that TBX1 is required for systemic lymphatic vessel development in prenatal mice and it is critical for their survival postnatally. Using loss-of-function genetics and transgenesis in the mouse, we show here a strong genetic interaction between Tbx1 and Vegfr3 in cardiac lymphangiogenesis. Intriguingly, we found that different aspects of the cardiac lymphatic phenotype in Tbx1-Vegfr3 compound heterozygotes were regulated independently by the two genes, with Tbx1 primarily regulating vessel numbers and Vegfr3 vessel morphology. Consistent with this observation, Tbx1Cre -activated expression of a Vegfr3 transgene rescued partially the cardiac lymphatic abnormalities in compound heterozygotes. Through time-controlled genetic experiments, we show that Tbx1 is activated and required in cardiac lymphatic endothelial cell (LEC) progenitors between E10.5 and E11.5. Furthermore, we found that it is also required later in development for the growth of the cardiac lymphatics. Finally, our study revealed a differential sensitivity between ventral and dorsal cardiac lymphatics to the effects of altered Tbx1 and Vegfr3 gene dosage, and we show that this likely results from an earlier requirement for Tbx1 in ventral cardiac LEC progenitors.Saffron (Crocus sativus L) is a well-known spice with active pharmacologic components including crocin, crocetin, safranal, and picrocrocin. Similar to crocin/crocetin, mesenchymal stem cells (MSCs) have been shown to display immunomodulatory and antioxidant properties, which could be beneficial in treatment of various diseases. In the current study, we have evaluated the effects of crocin and crocetin on the functions of MSCs. We used the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay to evaluate MSCs proliferation, and flow cytometry assay to measure the percentage of apoptotic MSCs and Tregs populations. Furthermore, we used the real-time polymerase chain reaction method to quantify messenger RNA (mRNA) expression of inflammatory and anti-inflammatory cytokines. Antioxidant assay was employed to quantify antioxidant parameters including nitric oxide and malondialdehyde levels besides superoxide dismutase activity. Our findings indicated that both crocin and crocetin at low concentrations (2.
