Structural basis of RNAPII transcription on the nucleosome containing histone variant H2A.B
The EMBO JournalH2A.B is a distant histone H2A variant associated with actively transcribed regions of the genome, suggesting its positive role in promoting transcription.

Molecular Oncology, EarlyView.In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Nature Communications, 2022 Antoniou and colleagues used base editing to generate a variety of mutations inducing γ-globin and rescue the β-hemoglobinopathy phenotype. This strategy was safe and effective in long-term repopulating hematopoietic stem/progenitor cells.

Chromatin and Epigenetics [PDF]
Plant Physiology, 2015 Wrapping DNA around protein beads, to form so-called nucleosomes, is an ingenious invention of nature allowing the condensation of an enormous amount of genomic information into a tiny package.

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma
Molecular Oncology, EarlyView.The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

In vitro Histone H3 Cleavage Assay for Yeast and Chicken Liver H3 Protease
Bio-Protocol, 2017 Histone proteins are subjected to a wide array of reversible and irreversible post-translational modifications (PTMs) (Bannister and Kouzarides, 2011; Azad and Tomar, 2014).

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3
Molecular Oncology, EarlyView.PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.
