Molecular basis for modulation of the p53 target selectivity by KLF4 [PDF]

, 2012
The tumour suppressor p53 controls transcription of various genes involved in apoptosis, cell-cycle arrest, DNA repair and metabolism. However, its DNA-recognition specificity is not nearly sufficient to explain binding to specific locations in vivo ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

PICALM::MLLT10 translocated leukemia

FEBS Letters, EarlyView.
This comprehensive review of PICALM::MLLT10 translocated acute leukemia provides an in‐depth review of the structure and function of CALM, AF10, and the fusion oncoprotein (1). The multifaceted molecular mechanisms of oncogenesis, including nucleocytoplasmic shuttling (2), epigenetic modifications (3), and disruption of endocytosis (4), are then ...

Surface plasmon resonance imaging of the conversion of clustered DNA lesions into double strand breaks by Fpg protein

AIMS Materials Science, 2015
Ionizing radiations induce clustered damage sites known to be severely challenging for the cell's repair machinery. In the present study, we have grafted on a biochip four synthetic oligonucleotide duplexes containing either a single 8-oxoguanine, a ...

Early neuronal accumulation of DNA double strand breaks in Alzheimer's disease. [PDF]

, 2019
The maintenance of genomic integrity is essential for normal cellular functions. However, it is difficult to maintain over a lifetime in postmitotic cells such as neurons, in which DNA damage increases with age and is exacerbated by multiple neurological

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

FEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Clusters of S1 Nuclease-Hypersensitive Sites Induced In Vivo by DNA Damage [PDF]

Molecular and Cellular Biology, 1997
DNA end-labeling procedures were used to analyze both the frequency and distribution of DNA strand breaks in mammalian cells exposed or not to different types of DNA-damaging agents. The 3' ends were labeled by T4 DNA polymerase-catalyzed nucleotide exchange carried out in the absence or presence of Escherichia coli endonuclease IV to cleave abasic ...

Genomic and experimental evidence for multiple metabolic functions in the RidA/YjgF/YER057c/UK114 (Rid) protein family. [PDF]

, 2015
BackgroundIt is now recognized that enzymatic or chemical side-reactions can convert normal metabolites to useless or toxic ones and that a suite of enzymes exists to mitigate such metabolite damage.

The early life microbiota protects neonatal mice from pathological small intestinal epithelial cell shedding [PDF]

, 2020
The early life gut microbiota plays a crucial role in regulating and maintaining the intestinal barrier, with disturbances in these communities linked to dysregulated renewal and replenishment of intestinal epithelial cells.

Adenosine‐to‐inosine editing of miR‐200b‐3p is associated with the progression of high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.
