Molecular Oncology, EarlyView.Breast tumor samples scored for metabolic deregulation (M1 to M3) were given a hypoxia score (HS). The highest HS occurred in patients with strongest metabolic deregulation (M3), supporting tumor aggressiveness. HS correlated with the highest number of metabolic pathways in M1. This suggests hypoxia to be an early event in metabolic deregulation.

Molecular Oncology, EarlyView.Analysis of ESR1 mutations in plasma cell‐free DNA (cfDNA) is highly important for the selection of treatment in patients with breast cancer. Using multiplex‐ddPCR and identical blood draws, we investigated whether circulating tumor cells (CTCs) and cfDNA provide similar or complementary information for ESR1 mutations.

Will epigenetics ever be a biosocial science? A reply to Chiapperino and Paneni
Epigenetics Communications, 2023 The recent correspondence article by Chiapperino and Paneni in Clinical Epigenetics correctly points to the inability of epigenetics to incorporate fine-grained mapping data of the individual’s surrounding milieu.

Epigenetics: What it is about? [PDF]
Biopolymers and Cell 2014, 2015 Epigenetics has captured the attention of scientists in the past decades, yet its scope has been continuously changing. In this paper, we give an overview on how and why its definition has evolved and suggest several clarification on the concepts used in this field, in particular, on the notions of epigenetic information, epigenetic stability and ...

KMT2A degradation is observed in decitabine‐responsive acute lymphoblastic leukemia cells
Molecular Oncology, EarlyView.We demonstrate that decitabine (DEC) not only degrades the DNA methyltransferase DNMT1 but also the leukemic driver lysine methyltransferase KMT2A likely due to structural similarity of the DNA‐binding CXXC domains. DEC influences KMT2A downstream processes and synergizes with menin inhibitor revumenib (REV) to decrease leukemic cell proliferation, and

Molecular Oncology, EarlyView.CD226+CD8+ T cells express elevated levels of RUNX2, exhibit higher proliferation capacity, cytokines and cytolytic molecules expression, and migratory capacity. In contrast, CD226−CD8+ T cells display an exhausted phenotype associated with the increased expression of co‐inhibitory receptors and impaired effector functions.

Molecular Oncology, EarlyView.In molecular cancer diagnostics, comprehensive genomic profiling (CGP) is going to replace the small NGS panels since it provides all clinically relevant somatic variants as well as genomic biomarkers with clinical value. Here, we compared two CGP assays and demonstrate that the choice for diagnostic implementation will depend on the specific ...

Cell size sets the diameter of the budding yeast contractile ring
Nature Communications, 2020 Budding yeast cell polarization is known to self-assemble, but it is still not clear what controls the size of the resulting septin ring. Here the authors show that the septin ring diameter is set by cell volume, ensuring that larger cells have larger ...

Cell division drives DNA methylation loss in late-replicating domains in primary human cells
Nature Communications, 2022 DNA methylation loss has been observed in aging tissues and cancers for decades. Researchers from Van Andel Institute have now provided experimental evidence that this process is directly driven by cell division.
