SWI/SNF (SWItch/Sucrose Non-Fermentable) is the most frequently mutated chromatin-remodelling complex in human malignancy, with over 20% of tumours having a mutation in a SWI/SNF complex member. Mutations in specific SWI/SNF complex members are characteristic of rare chemoresistant ovarian cancer histopathological subtypes. Somatic mutations in , encoding one of the mutually exclusive DNA-binding subunits of SWI/SNF, occur in 42-67% of ovarian clear cell carcinomas (OCCC).

  • Excision repair cross-complementation group 2 (ERCC2) is key for DNA repair, and mutations in this gene are found in about 10% of bladder cancer cases, potentially indicating how well patients respond to cisplatin therapy.
  • * In a study, mutations in ERCC2 were found to independently predict prognosis for bladder cancer and significantly change the mutation patterns in the genome, leading to specific mutation hotspots.
  • * Researchers used these findings to create a machine learning model that may help predict harmful ERCC2 mutations, aiming to improve treatment strategies for bladder cancer patients.

Gynecological and obstetric infectious diseases are crucial to women's health. There is growing evidence that links the presence of (), an anaerobic oral commensal and potential periodontal pathogen, to the development and progression of various human diseases, including cancers. While the role of this opportunistic oral pathogen has been extensively studied in colorectal cancer in recent years, research on its epidemiological evidence and mechanistic link to gynecological diseases (GDs) is still ongoing.

Glioblastoma cells can restrict the DNA-damaging effects of temozolomide (TMZ) and radiation therapy (RT) using the DNA damage response (DDR) mechanism which activates cell cycle arrest and DNA repair pathways. Ataxia-telangiectasia and Rad3-Related protein (ATR) plays a pivotal role in the recognition of DNA damage induced by chemotherapy and radiation causing downstream DDR activation. Here, we investigated the activity of gartisertib, a potent ATR inhibitor, alone and in combination with TMZ and/or RT in 12 patient-derived glioblastoma cell lines.

Vasculogenic mimicry (VM), the ability of tumour cells to form functional microvasculature without an endothelial lining, may contribute to anti-angiogenic treatment resistance in glioblastoma. We aimed to assess the extent of VM formation in primary and recurrent glioblastomas and to determine whether VM vessels also express prostate-specific membrane antigen (PSMA), a pathological vessel marker. Formalin-fixed paraffin-embedded tissue from 35 matched pairs of primary and recurrent glioblastoma was immunohistochemically labelled for PSMA and CD34 and stained with periodic acid-Schiff (PAS).

Article Synopsis
  • This Letter presents a precise measurement of the antineutrino spectrum from a reactor fueled exclusively with ^{235}U, using data from the PROSPECT-I detector.
  • The analysis doubled the previous measurements by utilizing previously unused segments of the detector, leading to a more accurate reconstruction of the antineutrino energy spectrum.
  • A notable excess in the antineutrino counts is observed in the 5-7 MeV energy range, indicating that the behavior of antineutrinos from ^{235}U cannot exclusively account for this anomaly compared to commercial reactors.

Introduction: Timely access to early support that optimises autistic children's development and their caregiver's mental health is critical. Naturalistic developmental behavioural interventions (NDBIs) and acceptance and commitment therapy (ACT) are evidence-based supports that can enhance child learning and behaviour, and adult well-being, respectively. The traditional face-to-face delivery of these approaches is resource intensive.

Fatty acids (FAs) and FA methyl esters (FAMEs) are easily isolated from vegetable oil and are important starting materials for the chemical industry to produce commercial products that are green, biorenewable, and nontoxic. A challenge in these applications is that mixtures of five or more FAs and FAMEs are isolated from a vegetable oil source, and methods to separate these mixtures are decades old and have increasingly high costs associated with the production of high-purity single-component FAs or FAMEs. We developed a method to separate these mixtures using mixed matrix membranes containing nanometer-sized covalent organic frameworks.
