Association of radiation-induced normal tissue toxicity with a high genetic risk for rheumatoid arthritis.

J Natl Cancer Inst

January 2025

Translational Radiobiology Group, Division of Cancer Sciences, University of Manchester, The Christie NHS Foundation Trust, Manchester, United Kingdom.

Purpose: Overlapping genes are involved with rheumatoid arthritis (RA) and DNA repair pathways. Therefore, we hypothesised that patients with a high polygenic risk score (PRS) for RA will have an increased risk of radiotherapy (RT) toxicity given the involvement of DNA repair.

Methods: Primary analysis was performed on 1494 prostate cancer, 483 lung cancer and 1820 breast cancer patients assessed for development of RT toxicity in the REQUITE study.

The chromosomal translocation t(1;6)(p35.3;p25.2), recurrent in chronic lymphocytic leukaemia, leads to RCC1::IRF4 fusion.

Br J Haematol

December 2024

The Ernest and Helen Scott Haematological Research Institute, Leicester Cancer Research Centre, University of Leicester, Leicester, UK.

Article Synopsis
  • * A study of 10 cases revealed that this translocation connects the interferon regulatory factor 4 (IRF4) gene on chromosome 6 with the regulator of chromosome condensation 1 (RCC1) gene on chromosome 1, resulting in fusion transcripts.
  • * Despite the fusion, the expression levels of RCC1 and IRF4 proteins remained normal, and the cases also displayed typical mutations related to CLL, suggesting a linkage with the IGHV-unmutated subtype.

Article Synopsis
  • Tobacco consumption has been linked to human health issues, but its specific impact on the bone metabolome hasn't been studied until now.
  • This research investigates the differences in metabolomic profiles of cortical bone between archaeological individuals who used tobacco and those who did not, using advanced mass spectrometry techniques.
  • The study found 45 distinct molecular features that can differentiate between tobacco users and non-users, indicating that such metabolic evidence remains even postmortem and can potentially identify individuals’ tobacco use status even when it's unknown.

Altered hepatic metabolic landscape and insulin sensitivity in response to pulmonary tuberculosis.

PLoS Pathog

September 2024

Department of Respiratory Sciences, Leicester TB Research Group, University of Leicester, Leicester, United Kingdom.

Article Synopsis
  • Chronic inflammation from pulmonary tuberculosis (TB) affects liver metabolism, leading to metabolic disorders by altering gene expression related to immune signaling and reducing metabolic processes.
  • Analysis showed upregulation of interferon (IFN) signaling genes and downregulation of gluconeogenesis-related genes in TB-infected mice's livers.
  • The study also found a correlation between metabolic changes in humans with TB and the progress of the disease, suggesting that TB-induced inflammation significantly impairs liver function and insulin sensitivity.

Epidermal growth factor receptor (EGFR) kinase has been implicated in the uncontrolled cell growth associated with non-small cell lung cancer (NSCLC). This has prompted the development of 3 generations of EGFR inhibitors over the last 2 decades due to the rapid development of drug resistance issues caused by clinical mutations, including T790M, L858R and the double mutant T790M & L858R. In this work we report the design, preparation and biological assessment of new irreversible 2,4-diaminopyrimidine-based inhibitors of EGFR kinase.

Whole-genome sequencing (WGS) and whole-exome sequencing (WES) are crucial within the context of breast cancer (BC) research. They play a role in the detection of predisposed genes, risk stratification, and identification of rare single nucleotide polymorphisms (SNPs). These technologies aid in the discovery of associations between various syndromes and BC, understanding the tumour microenvironment (TME), and even identifying unknown mutations that could be useful in future for personalised treatments.
