BRAT1 - a new therapeutic target for glioblastoma.

Cell Mol Life Sci

January 2025

Experimental Neurosurgery, Department of Neurosurgery, Neuroscience Center, Goethe University Hospital, Goethe University Frankfurt, 60528, Frankfurt am Main, Germany.

Glioblastoma (GBM), the most malignant primary brain tumor in adults, has poor prognosis irrespective of therapeutic advances due to its radio-resistance and infiltrative growth into brain tissue. The present study assessed functions and putative druggability of BRCA1-associated ATM activator 1 (BRAT1) as a crucial factor driving key aspects of GBM, including enhanced DNA damage response and tumor migration. By a stable depletion of BRAT1 in GBM and glioma stem-like (GSC) cell lines, we observed a delay in DNA double-strand break repair and increased sensitivity to radiation treatment, corroborated by in vitro and in vivo studies demonstrating impaired tumor growth and invasion.

Unlabelled: The concept of genome-microbiome interactions, in which the microenvironment determined by host genetic polymorphisms regulates the local microbiota, is important in the pathogenesis of human disease. In otolaryngology, the resident bacterial microbiota is reportedly altered in non-infectious ear diseases, such as otitis media pearls and exudative otitis media. We hypothesized that a single-nucleotide polymorphism in the ATP-binding cassette sub-family C member 11 () gene, which determines earwax properties, regulates the ear canal microbiota.

Article Synopsis
  • Elderly patients often face feeding and swallowing issues, leading to the use of the simple suspension method where tablets are dissolved in warm water for tube administration without crushing.
  • A study using verapamil revealed that drug release was faster from crushed tablets than from the simple suspension or intact tablets, indicating significant differences in dissolution profiles.
  • While both crushing and simple suspension methods can safely help patients with dysphagia, they may also increase the risk of side effects, so it's advisable to avoid altering medications before giving them.

Article Synopsis
  • Progranulin (PGRN) is a neurotrophic and anti-inflammatory protein, and its loss due to human mutations is linked to frontotemporal dementia, with PGRN knockout (KO) mice used to model this condition.
  • Restoration of PGRN in neurons (but not microglia) was achieved in a specific mouse model, allowing researchers to investigate if it could reduce brain damage after traumatic brain injury (TBI).
  • Findings indicated that restoring PGRN in neurons was enough to mitigate excessive brain damage caused by TBI, suggesting that microglial PGRN was not necessary for neuroprotection and anti-inflammatory effects in this context.

MHC class I polypeptide-related sequence B shedding modulates pancreatic tumor immunity via the activation of NKG2D T cells.

Sci Rep

October 2024

Department of Clinical Immuno Oncology, Clinical Research Institute for Clinical Pharmacology and Therapeutics, Showa University, 6-11-11 Kita-karasuyama, Setagaya-ku, Tokyo, 157-8577, Japan.

Article Synopsis
  • Natural killer group 2 member D ligands (NKG2DLs) in cancer cells can either activate immune responses or help tumors evade them, depending on their levels in the cells.
  • In pancreatic cancer cells (PANC-1), soluble MICB (sMICB) is found in the culture supernatant, which may saturate NKG2D T cells and inhibit their activation by membrane-bound MICB (mMICB).
  • Inhibiting the enzyme ADAM17, which contributes to the shedding of MICB, can help maintain mMICB expression and enhance NKG2D T cell activation, demonstrating a potential strategy to improve anti-tumor immune responses.
