      There are three prolyl hydroxylases (PHD1, 2 and 3) that regulate the hypoxia-inducible factors (HIFs), the master transcriptional regulators that respond to changes in intracellular O(2) tension. In high O(2) tension (normoxia) the PHDs hydroxylate two conserved proline residues on HIF-1α, which leads to binding of the von Hippel-Lindau (VHL) tumour suppressor, the recognition component of a ubiquitin-ligase complex, initiating HIF-1α ubiquitylation and degradation. However, it is not known whether PHDs and VHL act separately to exert their enzymatic activities on HIF-1α or as a multiprotein complex. Here we show that the tumour suppressor protein LIMD1 (LIM domain-containing protein) acts as a molecular scaffold, simultaneously binding the PHDs and VHL, thereby assembling a PHD-LIMD1-VHL protein complex and creating an enzymatic niche that enables efficient degradation of HIF-1α. Depletion of endogenous LIMD1 increases HIF-1α levels and transcriptional activity in both normoxia and hypoxia. Conversely, LIMD1 expression downregulates HIF-1 transcriptional activity in a manner depending on PHD and 26S proteasome activities. LIMD1 family member proteins Ajuba and WTIP also bind to VHL and PHDs 1 and 3, indicating that these LIM domain-containing proteins represent a previously unrecognized group of hypoxic regulators.

    • A selective deficit for reading vowels in a letter-by-letter reader

      Jonsdottir, M K (Sveriges neuropsykologers förening, 2004-11)
      BM, a patient with fluent aphasia and severe alexia without agraphia is presented. He manifests a clear word length effect which is the hallmark of letter-by-letter reading. However, this letter-by-letter reader comes with an unusual twist, namely a selective difficulty in reading vowels, both in words and non-words. BM´s reading was not influenced by word class, imageability or word frequency. Only one other similar case is known in the literature.

    • T cell receptor gene therapy targeting WT1 prevents acute myeloid leukemia relapse post-transplant.

      Chapuis, Aude G; Egan, Daniel N; Bar, Merav; Schmitt, Thomas M; McAfee, Megan S; Paulson, Kelly G; Voillet, Valentin; Gottardo, Raphael; Ragnarsson, Gunnar B; Bleakley, Marie; et al. (Nature Publishing Group, 2019-07)
      Relapse after allogeneic hematopoietic cell transplantation (HCT) is the leading cause of death in patients with acute myeloid leukemia (AML) entering HCT with poor-risk features1-3. When HCT does produce prolonged relapse-free survival, it commonly reflects graft-versus-leukemia effects mediated by donor T cells reactive with antigens on leukemic cells4. As graft T cells have not been selected for leukemia specificity and frequently recognize proteins expressed by many normal host tissues, graft-versus-leukemia effects are often accompanied by morbidity and mortality from graft-versus-host disease5. Thus, AML relapse risk might be more effectively reduced with T cells expressing receptors (TCRs) that target selected AML antigens6. We therefore isolated a high-affinity Wilms' Tumor Antigen 1-specific TCR (TCRC4) from HLA-A2+ normal donor repertoires, inserted TCRC4 into Epstein-Bar virus-specific donor CD8+ T cells (TTCR-C4) to minimize graft-versus-host disease risk and enhance transferred T cell survival7,8, and infused these cells prophylactically post-HCT into 12 patients ( NCT01640301 ). Relapse-free survival was 100% at a median of 44 months following infusion, while a concurrent comparative group of 88 patients with similar risk AML had 54% relapse-free survival (P = 0.002). TTCR-C4 maintained TCRC4 expression, persisted long-term and were polyfunctional. This strategy appears promising for preventing AML recurrence in individuals at increased risk of post-HCT relapse.

    • Towards an Individualized Nutrition Treatment: Role of the Gastrointestinal Microbiome in the Interplay Between Diet and Obesity.

      Dietary treatments for obesity have relatively low long-term success. Recent studies have identified the gastrointestinal microbiome as a factor of high relevance. The current knowledge on the interplay between diet, obesity, and the gastrointestinal microbiome and the potential for individualized dietary treatment will be discussed. Studies indicate that each individual digests and metabolizes identical food substances differently depending on their gastrointestinal microbiome composition. Factors related to this crosstalk may improve our understanding of weight homeostasis and treatment of obesity. Long-time dietary intake is the key in the composition of the gastrointestinal microbiome which seems to be an important factor for energy balance, resulting in emerging opportunities for increasingly varied obesity treatment. Compliance to dietary treatment is critical for long-term success as enduring changes in gastrointestinal microbiome seem to slow over time. More research is urgently needed to investigate this missing link in our understanding of obesity.
