Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes

FEBS Letters, EarlyView.
The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

Asymmetric division of stem cells and its cancer relevance

Cell Regeneration
Asymmetric division is a fundamental process for generating cell diversity and maintaining the stem cell population. During asymmetric division, proteins, organelles, and even RNA are distributed unequally between the two daughter cells, determining ...

Mitochondrial fatty acid oxidation is stimulated by red light irradiation

FEBS Letters, EarlyView.
Light at different wavelengths has distinct effects on keratinocyte viability and metabolism. UVA light abrogates metabolic fluxes. Blue and green light have no effect on metabolic fluxes, while red light enhanced oxidative phosphorylation by promoting fatty acid oxidation. Keratinocytes are the primary constituents of sunlight‐exposed epidermis.

Engineering a CRISPR-associated IscB system for developing miniature genome-editing tools in human cells and mouse embryos

Nature Communications
IscB, as the putative ancestor of Cas9, possesses a compact size, making it suitable for in vivo delivery. OgeuIscB is the first IscB protein known to function in eukaryotic cells but requires a complex TAM (NWRRNA).

Targeting mutant p53 in cancer: the latest insights

Journal of Experimental & Clinical Cancer Research, 2019
This commentary wishes to highlight the latest discoveries in the mutant p53 field that have been discussed in the 8th p53 Mutant Workshop 2019, held in Lyon. TP53 mutant (mutp53) proteins are involved in the pathogenesis of most human cancers.

The IQ‐compete assay for measuring mitochondrial protein import efficiencies in living yeast cells

FEBS Letters, EarlyView.
The efficiency of mitochondrial protein import depends on the properties of the newly synthesized precursor proteins. The Import and de‐Quenching Competition (IQ‐compete) assay is a novel method to monitor the import efficiency of different proteins by fluorescence in living yeast cells.

scIVNL-seq resolves in vivo single-cell RNA dynamics of immune cells during Salmonella infection

Nature Communications
The immune response against pathogens involves multiple cell state transitions and complex gene expression changes. Here, we establish a single-cell in vivo new RNA labeling sequencing method (scIVNL-seq) and apply it to survey time-resolved RNA dynamics

Targeting EZH2 reverses thyroid cell dedifferentiation and enhances iodide uptake in anaplastic thyroid cancer

FEBS Letters, EarlyView.
Anaplastic thyroid cancer (ATC) lacks iodide uptake ability due to MAPK activation increasing the expression of the histone methyltransferase EZH2, which represses thyroid differentiation genes (TDGs) such as the sodium iodide symporter (NIS). Dual inhibition of MAPK (U0126) and EZH2 (EPZ6438/Tazemetostat) reverses this mechanism, thus restoring TDG ...

Deciphering histone mark-specific fine-scale chromatin organization at high resolution with Micro-C-ChIP

Nature Communications
The regulation of cell-type-specific transcription relies on complex 3D interactions between promoters and distal regulatory elements. Although Hi-C has advanced our understanding of genome architecture, its high sequencing demand limits use in large ...

The oncogenic role of circPVT1 in head and neck squamous cell carcinoma is mediated through the mutant p53/YAP/TEAD transcription-competent complex

Genome Biology, 2017
Background Circular RNAs are a class of endogenous RNAs with various functions in eukaryotic cells. Worthy of note, circular RNAs play a critical role in cancer. Currently, nothing is known about their role in head and neck squamous cell carcinoma (HNSCC)
