Article Synopsis
  • The study investigates how cancer cells influence the fitness of surrounding tumor microenvironment (TME) cells through a mechanism involving a long non-coding RNA called Tu-Stroma, which alters the expression of Flower isoforms, impacting their growth advantage.
  • The expression of Flower Win isoforms in cancer cells enhances their dominance over TME cells that express Flower Lose isoforms, leading to reduced fitness in the TME.
  • Targeting Flower proteins with a humanized monoclonal antibody in mice has shown promising results, significantly reducing cancer growth and metastasis while improving survival rates and protecting organs from potential lesions.

Initial clinical trials with drugs targeting epigenetic modulators - such as bromodomain and extraterminal protein (BET) inhibitors - demonstrate modest results in acute myeloid leukemia (AML). A major reason for this involves an increased transcriptional plasticity within AML, which allows cells to escape the therapeutic pressure. In this study, we investigated immediate epigenetic and transcriptional responses following BET inhibition and could demonstrate that BET inhibitor-mediated release of BRD4 from chromatin is accompanied by an acute compensatory feedback that attenuates down-regulation, or even increases expression, of specific transcriptional modules.

In radiology, technological progress has led to an enormous increase in data volumes. To effectively use these data during diagnostics or subsequent clinical evaluations, they have to be aggregated at a central location and be meaningfully retrievable in context. Radiology data warehouses undertake this task: they integrate diverse data sources, enable patient-specific and examination-specific evaluations, and thus offer numerous benefits in patient care, education, and clinical research.

Calcium and vitamin D substitution for hypoparathyroidism after thyroidectomy - how is it continued after discharge from hospital?

Langenbecks Arch Surg

December 2024

Section of Endocrine Surgery, Department of General, Visceral and Transplantation Surgery, University Medical Center, Johannes Gutenberg University Mainz, Langenbeckstraße 1, D-55131, Mainz, Germany.

Article Synopsis
  • The study focuses on managing postoperative hypoparathyroidism (HypoPT) after thyroid surgery, which often requires calcium and active vitamin D supplements.
  • During a retrospective analysis from March 2015 to December 2023 at UMC Mainz, it was found that only 28.3% of patients continued receiving these supplements post-discharge, despite varying levels of parathyroid hormone (PTH) and calcium.
  • The results highlighted inconsistencies in how external practitioners adjust these supplements, suggesting that thyroid surgeons should recommend a structured reduction plan to prevent excessive calcium intake and potential kidney issues.

Background: An increasing number of HCC develops in the context of metabolic dysfunction-associated steatotic liver disease and its inflammatory form, metabolic dysfunction-associated steatohepatitis, even in the absence of cirrhosis. Chronic metabolic inflammation is the driving force of metabolic dysfunction-associated steatotic liver disease progression and a key factor in hepatocarcinogenesis. Given the prominent role of IL-1 signaling in inflammation and metabolic diseases, we investigated the relevance of the hepatocyte-specific IL-1 receptor type 1 knockout in metabolic dysfunction-associated steatohepatitis-related noncirrhotic HCC.
