- The number of transporter proteins that are not fully characterized is immense. Here, we used Drosophila melanogaster and human cell lines to perform a first in-depth characterization of CG4928, an ortholog to the human UNC93A, of which little is known. Solute carriers regulate and maintain biochemical pathways important for the body, and malfunctioning transport is associated with multiple diseases. Based on phylogenetic analysis, CG4928 is closely related to human UNC93A and has a secondary and a tertiary protein structure and folding similar to major facilitator superfamily transporters. Ubiquitous knockdown of CG4928 causes flies to have a reduced secretion rate from the Malpighian tubules; altering potassium content in the body and in the Malpighian tubules, homologous to the renal system; and results in the development of edema. The edema could be rescued by using amiloride, a common diuretic, and by maintaining the flies on ion-free diets. CG4928-overexpressing cells did not facilitate the transport of sugars and amino acids; however, proximity ligation assay revealed that CG4928 co-localized with TASK(1) channels. Overexpression of CG4928 resulted in induced apoptosis and cytotoxicity, which could be restored when cells were kept in high-sodium media. Furthermore, the basal membrane potential was observed to be disrupted. Taken together, the results indicate that CG4928 is of importance for generating the cellular membrane potential by an unknown manner. However, we speculate that it most likely acts as a regulator or transporter of potassium flows over the membrane.

- Cellular transport and function are dependent on substrate influx and efflux of various compounds. In humans, the largest superfamily of transporters is the SoLute Carriers (SLCs). Many transporters are orphans and little to nothing is known about their expression and/or function, yet they have been assigned to a cluster called atypical SLCs. One of these atypical SLCs is MFSD11. Here we present a first in-depth characterization of the MFSD11, CG18549. By gene expression and behavior analysis on ubiquitous and brain-specific knockdown flies. CG18549 knockdown flies were found to have altered adipokinetic hormone and adipokinteic hormone receptor expression as well as reduced vesicular monoamine transporter expression; to exhibit an altered locomotor behavior, and to have an altered reaction to stress stimuli. Furthermore, the gene expression of CG18549 in the brain was visualized and abundant expression in both the larvae and adult brain was observed, a result that is coherent with the FlyAtlas Anatomy microarray. The exact mechanism behind the observed behaviors is not fully understood, but this study provides new insights into the expression and function of CG18549. Clearly, these results provide a strong example as to why it is vital to fully characterize orphan transporters and through that gain knowledge about the body during normal condition and disease.

Patientinformation avseende bröstcancer och diabetes : en utvärdering
- 1998
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Avsikten med studien var att i första hand undersöka hur patientinformation uppfattas av personer med två sjukdomar - bröstcancer och diabetes. den patientinformation som avsågs var dels information från hälso- och sjukvården och dels information från andra källor. Ett delsyfte var att låta personer med erfarenhet av tidigare nämnda sjukdomar bedöma den patientinformation avseende bröstcancer och diabetes som finns i den medicinska faktadatabasen MARS. Underlaget för studien utgörs av materiel från fokusgrupper och efterföljande telefonintervjuer.

- Many transporters such as the solute carriers belonging to the Major facilitator superfamily Pfam clan are orphans in that their tissue and cellular localization as well as substrate profile and function are still unknown. Here we have characterized the putative solute carrier UNC93A. We aimed to investigate the expression profile on both protein and mRNA level of UNC93A in mouse since it has not been clarified. UNC93A staining was found in cortex, hippocampus and cerebellum. It was found to be expressed in many neurons, but not all, with staining located in close proximity to the plasma membrane. Furthermore, we aimed to extend the starvation data available for Unc93a in hypothalamic cell cultures from mouse. We investigated the Unc93a alterations with focus on amino acid deprivation in embryonic cortex cells from mice as well as 24 h starvation in adult male mice and compared it to recently studied putative and known solute carriers. Unc93a expression was found both in the brain and peripheral organs, in low to moderate levels in the adult mice and was affected by amino acid deprivation in embryonic cortex cultures and starvation in in vivo samples. In conclusion, the membrane-bound UNC93A is expressed in both the brain and peripheral tissues and responds to nutrient availability in mice.

- Trace elements (heavy metals and metalloids) are among the most widespread contaminants that pose serious threat to all living organisms. Plant and microbial-assisted remediation holds great promise for in situ remediation of trace element contaminated environments. An extended knowledge of plant processes generally involved in the uptake, translocation, storage and detoxification of contaminants, and plant-microbe interactions were essential in developing improved technologies for environmental clean up. Currently, with the initiation of transgenic technologies, great strides have been made in trace element phytoremediation research. In this review, we provide an overview of the current knowledge of how plants cope with trace elements and discuss the development of transgenic plants with improved trace element remediation capabilities. In addition, this review also addresses the recent progress made towards understanding the plant-microbe interactions, especially of endophytic bacteria (natural and genetically engineered), and their contribution in improving the efficiency and versatility of trace element phytoremediation.

- Background Patients with hematological malignancies are more susceptible to viral infections including influenza. In 2009, the World Health Organization classified the novel influenza A (H1N1) virus as pandemic. The potential impact of this pandemic for patients with hematological disorders was unknown. Institutional guidelines recommended two doses of AS03-adjuvanted influenza A (H1N1) 2009 pandemic vaccine for these patients. Objectives We aimed to determine the safety, immunogenicity, and clinical efficacy of this vaccine in patients with hematological diseases. Furthermore, we compared the immunological responses to that obtained by the non-adjuvanted trivalent seasonal influenza vaccine (TIV). Methods All included patients received adjuvanted pandemic vaccine and the majority received TIV. Serum for antibody analyses was collected at five time points. Results Thirty-one patients with different hematological diseases were included. After the second vaccine dose, a total of 25 (81%) reached both protective levels of antibodies and seroconversion response. Antibody titers1:40 persisted for 50% of responding patients at 1yr. Seroconversion was observed in 69% of 14 patients who had undergone hematopoietic stem cell transplantation and in all (9/9) patients with myeloma (five with ongoing treatment including high-dose corticosteroids). After vaccination with TIV, seroconversions against the three included strains were detected in 28%, 40%, and 20%. Response to the adjuvanted pandemic vaccine was superior (P<0.009). Conclusions A substantial proportion of patients with hematological malignancies including patients undergoing chemotherapy mounted a good response to the adjuvanted pandemic vaccine. This vaccine had superior immunogenicity as compared to the non-adjuvanted TIV.
