Overall, this study highlights the role of POC-derived GDNF in BMMSC migration and osteogenic differentiation, suggesting that GDNF regulates bone metabolism. [BMB Reports 2020; 53(12) 646-651].Skeletal myogenesis is a complex process that is finely regulated by myogenic transcription factors. Recent studies have shown that saturated fatty acids (SFA) can suppress the activation of myogenic transcription factors and impair the myogenic differentiation of progenitor cells. Despite the increasing evidence of the roles of miRNAs in myogenesis, the targets and myogenic regulatory mechanisms of miRNAs are largely unknown, particularly when myogenesis is dysregulated by SFA deposition. This study examined the implications of SFA-induced miR-183-5p on the myogenic differentiation in C2C12 myoblasts. Long-chain SFA palmitic acid (PA) drastically reduced myogenic transcription factors, such as myoblast determination protein (MyoD), myogenin (MyoG), and myocyte enhancer factor 2C (MEF2C), and inhibited FHL1 expression and myogenic differentiation of C2C12 myoblasts, accompanied by the induction of miR-183-5p. The knockdown of FHL1 by siRNA inhibited myogenic differentiation of myoblasts. Interestingly, miR-183-5p inversely regulated the expression of FHL1, a crucial regulator of skeletal myogenesis, by targeting the 3'UTR of FHL1 mRNA. find more Furthermore, the transfection of miR-183-5p mimic suppressed the expression of MyoD, MyoG, MEF2C, and MyHC, and impaired the differentiation and myotube formation of myoblasts. Overall, this study highlights the role of miR-183-5p in myogenic differentiation through FHL1 repression and suggests a novel miRNA-mediated mechanism for myogenesis in a background of obesity. [BMB Reports 2020; 53(11) 605-610].Osteosarcoma is the most prevailing malignant bone tumor among adolescents. Punicalagin, a polyphenolic compound extracted from pomegranate, possesses many functions such as anti-oxidation, anti-bacterial, anti-virus, and immunosuppression, which can counter the aggressiveness of a variety of cancers such cervical, ovarian and prostate. This study aimed to investigate the inhibitory effect of punicalagin on the proliferation and metastasis of osteosarcoma cells and its potential regulatory mechanisms. Osteosarcoma cell lines (HOS cells, U2OS cells and MG63 cells) were treated with different doses of punicalagin, and the effects on osteosarcoma cell activity were examined in vitro using cell counting kit-8 (CCK-8), colony formation and apoptosis assays. The mobility, migration and invasion abilities of osteosarcoma cells were detected by wound healing and Transwell assays. NF-κB activity was explored by the NF-κB p65 luciferase reporter assay. Western blot was used to investigate the expressions of downstream proteins. We found that punicalagin inhibited the viability of osteosarcoma cells in vitro in dose-dependent and time-dependent manners and promoted apoptosis. In addition, punicalagin could significantly impede the mobility, migration and invasion abilities of osteosarcoma cells. In terms of mechanism, punicalagin down-regulated the expressions of p65, survivin, XIAP, CIAP2 and other proteins, and suppressed the proliferation and metastasis of osteosarcoma cells by repressing NF-κB signaling pathway. In conclusion, it is concluded that punicalagin restrains the growth and metastasis of osteosarcoma by obstructing the NF-κB signal transduction pathway.A central function of health technology assessment (HTA) agencies is the production of HTA reports to support evidence-informed policy and decision making. HTA agencies are interested in understanding the mechanisms of HTA impact, which can be understood as the influence or impact of HTA report findings on decision making at various levels of the health system. The members of the International Network of Agencies for HTA (INAHTA) meet at their annual Congress where impact story sharing is one important activity. This paper summarizes four stories of HTA impact that were finalists for the David Hailey Award for Best Impact Story.The methods to measure impact include document review; claims analysis and review of reimbursement status; citation analysis; qualitative evaluation of stakeholders' views; and review of media response. HTA agency staff also observed changes in government activities and priorities based on the HTA. Impact assessment can provide information to improve the HTA process, for example, the value of patient and clinician engagement in the HTA process to better define the assessment question and literature reviews in a more holistic and balanced way.HTA reports produced by publicly funded HTA agencies are valued by health systems around the globe as they support decision making regarding the appropriate use, pricing, reimbursement, and disinvestment of health technologies. HTAs can also have a positive impact on information sharing between different levels of government and across stakeholder groups. These stories show how HTA can have a significant impact, irrespective of the health system and health technology being assessed.The coronavirus disease-2019 (COVID-19) pandemic is a public health emergency of international concern. This pandemic poses a challenge to research and scientific community. In this study, we developed and tested content reliability and content validity of a questionnaire designed for evaluating the readiness and willingness of researchers to participate in virology research in Jordan. The survey was hosted on an online platform, and the link was emailed. A total of 332 participants from universities across Jordan completed the survey. For factor analysis, Kaiser-Meyer-Olkin value (KMO) and Bartlett's Test of Sphericity were conducted. Furthermore, exploratory factor analysis (EFA) with parallel analysis and scree plots were conducted to evaluate the most suitable model for the data. The result of the EFA suggested a 5-factor model would fit the survey. Data showed that the lowest means were for researchers' readiness to conduct virology research and readiness for virology research with means of 2.07 and 2.95, respectively. Moreover, years of experience and speciality had a significant effect on the readiness and willingness of virology research in Jordan. In conclusion, readiness for research and researchers should be addressed and authorities should pay attention to these shortcomings in virology research.
