Oncogenic BRAF and KRAS Promote Global DNA Hypomethylation Through a Directed Pathway That Upregulates TET3

Cancer Science, EarlyView.
Oncogenic BRAF and KRAS promote global DNA hypomethylation through a directed pathway that increases the levels of TET3, which helps drive tumorigenesis. ABSTRACT Aberrant epigenetic modification is one of the characteristics of the cancer genome.

Ezh2 Inhibits the Differentiation of Short‐Lived Effector CD8+ T Cells and Promotes T Cell‐Dependent Antitumor Immunity

Cancer Science, EarlyView.
The antitumor immune response is attenuated in T cell‐specific Ezh2 knockout mice. ABSTRACT Appropriate regulation of the differentiation balance between effector CD8+ T cells and memory CD8+ T cells is crucial for an appropriate immune response. We previously reported that the tumor suppressor menin suppresses the differentiation of CD8+ T cells into ...

Mechanisms of Thrombocytosis in Iron‐Deficiency Anemia

European Journal of Haematology, EarlyView.
ABSTRACT Iron‐deficiency anemia is frequently accompanied by reactive thrombocytosis, yet the mechanisms underlying this association remain incompletely understood. Beyond impaired erythropoiesis, iron availability has emerged as an active regulator of hematopoietic lineage decisions.

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

The epigenetic landscape of skeletal muscle in response to exercise and aging

The FEBS Journal, EarlyView.
Epigenetic mechanisms regulate gene expression in response to exercise and aging, thereby supporting skeletal muscle plasticity. Acute exercise induces chromatin remodeling through histone modifications and DNA methylation, promoting the expression of exercise‐responsive genes.

Understanding and addressing resistance to IMiDs immunomodulatory compounds in multiple myeloma

The FEBS Journal, EarlyView.
IMiDs are pivotal in the treatment of multiple myeloma. Mechanisms of resistance comprise cell intrinsic and extrinsic pathways, involving tumour microenvironment, immune cell dysfunction, CRBN‐dependent and independent genetic drivers and epigenetic changes.

Physiological media and oxygen levels modulate cancer hallmarks in cultured breast cancer cells

The FEBS Journal, EarlyView.
MCF7 breast cancer cells were cultured in standard conditions (18% O2 and DMEM) and physiological conditions (5% O2 and Plasmax, a medium modeled after the human plasma metabolome). A combined transcriptomic and proteomic approach was used to identify gene expression signatures at the mRNA and protein levels upstream of functional enrichment analyses ...

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Decoding stress resilience in soybean: Regulatory networks and precision breeding under climate change

Journal of Integrative Plant Biology, EarlyView.
This review covers recent progress in the understanding of stress‐responsive regulatory networks in soybean and highlights emerging genomic and breeding strategies. Integrating molecular insights and precision breeding will help to accelerate the development of climate‐resilient soybean cultivars.

Role of the tomato MARS1/ROUGH gene encoding a LYSINE‐SPECIFIC HISTONE DEMETHYLASE 1 in adventitious root and fruit skin formation

Journal of Integrative Plant Biology, EarlyView.
The tomato mars1/rough mutant displays enhanced root regeneration and rough fruits due to ectopic cell proliferation. The causal gene encodes a lysine‐specific histone demethylase that normally maintains gene silencing. Its loss alters histone methylation, upregulating several genes, including those B‐type cyclins involved in tissue‐specific cellular ...
