Abstract
Abstract
Background
The Collaboration for Evidence-based Healthcare and Public Health in Africa (CEBHA+) is an NCD research consortium that seeks to engage policy-makers and practitioners throughout the research process in order to build lasting relationships, enhance evidence uptake and build long-term capacity among partner institutions in Ethiopia, Malawi, Rwanda, South Africa and Uganda. This integrated knowledge translation (IKT) approach includes the formal development and implementation of country-specific engagement strategies.
Methods
An early-stage evaluation is taking place in Mid-2020. Online surveys and qualitative interviews with researchers and policy-and-practice partners will inform adaptation of country-specific strategies, advance the initial programme theory and contribute to the science of IKT.
Results
We present three pertinent observations based on the development and implementation of an overarching CEBHA+ IKT approach and five country-specific strategies over the last two years: Despite being informed by an overarching IKT programme theory, the site-specific strategies and resulting partnerships vary markedly, representing the whole continuum of integrated knowledge translation.The diversity of approaches is due to different understandings of IKT, discontinuity of staff, lack of IKT training, and perceptions of usefulness (compared to ongoing research activities) among CEBHA+ researchers.The individual, dynamic and often pre-existing relationships of researchers and partners from policy and practice are central to IKT, but capturing these within the programme theory and monitoring them remains challenging.
Conclusions
These observations are useful to guide further evaluation and cross-country comparison. Close examination of relationships and conceptualisation of IKT as a continuum may provide valuable insights into the circumstances that make IKT efforts worthwhile.
Key messages
Translating evidence into policy and practice is reliant on partnerships between researchers and policy-and-practice partners. These can be formalised but the relationships remain complex and dynamic.

Abstract
Health policy and systems research (HPSR) is vital to guiding global institutions, funders, policymakers, activists and implementers in developing and enacting strategies to achieve the Sustainable Development Goals. We undertook a multi-stage participatory process to identify priority research questions relevant to improving accountability within health systems. We conducted interviews (n = 54) and focus group discussions (n = 2) with policymakers from international and national bodies (ministries of health, other government agencies and technical support institutions) across the WHO regions. Respondents were asked to reflect on challenges and current policy discussions related to health systems accountability, and to identify their pressing research needs. We also conducted an overview of reviews (n = 34) to determine the current status of knowledge on health systems accountability and to identify any gaps. We extracted research questions from the policymaker interviews and focus groups (70 questions) and from the overview of reviews (112 questions), and synthesized these into 36 overarching questions. Using the online platform Co-Digital, we invited researchers from around the world to refine and then rank the questions according to research importance. The questions that emerged amongst the top priorities focused on political factors that mediate the adoption or effectiveness of accountability initiatives, processes and incentives that facilitate the acceptability of accountability mechanisms among frontline healthcare providers, and the national governance reforms and contexts that enhance provider accountability. The process revealed different underlying conceptions of social accountability and how best to promote it, with some researchers and policymakers focusing on specific interventions and others embracing a more systems-oriented approach to understanding accountability, the multiple forms that it can take, how these interact with each other and the importance of power and underlying social relations. The findings from this exercise identify HPSR funding priorities and future areas for evidence production and policy engagement.

Abstract
We have previously identified a CHO cell line (UT2 cells) that expresses only one 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase protein which is localized exclusively in peroxisomes [Engfelt, H.W., Shackelford, J.E., Aboushadi, N., Jessani, N., Masuda, K., Paton, V.G., Keller, G.A., and Krisans, S.K. (1997) J. Biol. Chem. 272, 24579-24587]. In this study, we utilized the UT2 cells to determine the properties of the peroxisomal reductase independent of the endoplasmic reticulum (ER) HMG-CoA reductase. We demonstrated major differences between the two proteins. The peroxisomal reductase is not the rate-limiting enzyme for cholesterol biosynthesis in UT2 cells. The peroxisomal reductase protein is not phosphorylated, and its activity is not altered in the presence of inhibitors of cellular phosphatases. Its rate of degradation is not accelerated in response to mevalonate. Finally, the degradation process is not blocked by N-acetyl-Leu-Leu-norleucinal (ALLN). Furthermore, the peroxisomal HMG-CoA reductase is significantly more resistant to inhibition by statins. Taken together, the data support the conclusion that the peroxisomal reductase is functionally and structurally different from the ER HMG-CoA reductase.

Abstract
In the liver 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase is present not only in the endoplasmic reticulum but also in the peroxisomes. However, to date no information is available regarding the function of the peroxisomal HMG-CoA reductase in cholesterol/isoprenoid metabolism, and the structure of the peroxisomal HMG-CoA reductase has yet to be determined. We have identified a mammalian cell line that expresses only one HMG-CoA reductase protein and that is localized exclusively to peroxisomes. This cell line was obtained by growing UT2 cells (which lack the endoplasmic reticulum HMG-CoA reductase) in the absence of mevalonate. The cells exhibited a marked increase in a 90-kDa HMG-CoA reductase that was localized exclusively to peroxisomes. The wild type Chinese hamster ovary cells contain two HMG-CoA reductase proteins, the well characterized 97-kDa protein, localized in the endoplasmic reticulum, and a 90-kDa protein localized in peroxisomes. The UT2 cells grown in the absence of mevalonate containing the up-regulated peroxisomal HMG-CoA reductase are designated UT2*. A detailed characterization and analysis of this cell line is presented in this study.
