Article Synopsis
  • Mutant isocitrate dehydrogenase 1 (mIDH1) creates excess 2-hydroxyglutarate (2HG), leading to changes in gene expression and making mIDH1 gliomas more resilient to DNA damage and radiation.* -
  • Research found mIDH1 glioma cells showed reduced mitochondrial metabolism and increased autophagy, which became their main energy source, indicating they rely heavily on autophagy for survival.* -
  • Blocking autophagy weakened the growth of mIDH1 glioma cells and, when combined with radiation, enhanced treatment effectiveness, suggesting targeting autophagy could improve therapies for mIDH1 glioma patients.*

Glioblastoma (GBM) is an aggressive primary brain cancer, with a 5 year survival of ∼5%. Challenges that hamper GBM therapeutic efficacy include (i) tumor heterogeneity, (ii) treatment resistance, (iii) immunosuppressive tumor microenvironment (TME), and (iv) the blood-brain barrier (BBB). The C-X-C motif chemokine ligand-12/C-X-C motif chemokine receptor-4 (CXCL12/CXCR4) signaling pathway is activated in GBM and is associated with tumor progression.

Background: Esophageal adenocarcinoma (EAC) is a molecularly heterogeneous disease with poor prognosis that is rising rapidly in incidence. We aimed to demonstrate specific binding by a peptide heterodimer to Barrett's neoplasia in human subjects.

Methods: Peptide monomers specific for EGFR and ErbB2 were arranged in a heterodimer configuration and labeled with IRDye800.

Sessile serrated adenomas (SSAs) are premalignant lesions driven by the BRAF mutation to give rise to colorectal cancers (CRCs). They are often missed during white light colonoscopy because of their subtle appearance. Previously, a fluorescently labeled 7mer peptide KCCFPAQ was shown to detect SSAs .

Background: Cribriform comedo-type adenocarcinoma was a colon cancer subtype recognised in the previous WHO classification of tumours that is no longer included in the recent edition. Previous reports have described colon cancers with cribriform growth as having worse overall survival and being associated with microsatellite stability. We sought to validate whether cribriform carcinoma (CC) is a distinct morphological subtype with clinical relevance in the context of modern colon cancer diagnosis.
