Epigenetic dysregulation has been implicated in a variety of pathological processes including carcinogenesis. A major group of enzymes that influence epigenetic modifications are lysine demethylases (KDMs) also known as "erasers" which remove methyl groups on lysine (K) amino acids of histones. Numerous studies have implicated aberrant lysine demethylase activity in a variety of cancers, including melanoma.

Background: Survival from melanoma is strongly related to patient sex, with females having a survival rate almost twice that of males. Many explanations have been proposed but have not withstood critical scrutiny. Prior analysis of different cancers with a sex bias has identified six X-linked genes that escape X chromosome inactivation in females and are, therefore, potentially involved in sex differences in survival.

Introduction: Recent studies have suggested that the VEGF inhibitors, Ranibizumab and Aflibercept may be associated with an excess of cardiovascular events, potentially driven by increasing atheroma instability, leading to plaque rupture and clinical events. Inflammation plays a key role in the progression of atherosclerotic plaque and particularly conversion to an unstable phenotype. Here, we sought to assess the in vitro effects of these drugs on the expression of key inflammatory mediators on endothelial cells.

Objective: Aberrant Wnt signalling has previously been associated with gynaecological cancers, and the aim of this study was to investigate the expression of Wnt5a in epithelial ovarian cancer, and clarify its role in activating or inhibiting β-catenin dependent and independent Wnt signalling pathways.

Method: Wnt5a expression was investigated in a large cohort of epithelial ovarian cancer patient samples using immunohistochemistry and correlated with clinicopathological variables. Wnt5a function was investigated in vitro in ovarian cell lines.

Article Synopsis
  • Iron chelators from the 2'-benzoylpyridine thiosemicarbazone (BpT) class show promise as anticancer agents, and new analogues with halogen substituents (XBpTs) were developed to study their effectiveness.
  • Some XBpT analogues demonstrated stronger antiproliferative effects than the original BpT compound, while also having a favorable therapeutic index, meaning they harmed healthy cells less than cancer cells.
  • The addition of halogens increased the redox potential of XBpT-Fe complexes and correlated with higher generation of reactive oxygen species (ROS), linking this increase to the observed anticancer activity in the more hydrophilic BpT compounds.
