TopBP1 utilises a bipartite GINS binding mode to support genome replication

Nature Communications
Activation of the replicative Mcm2-7 helicase by loading GINS and Cdc45 is crucial for replication origin firing, and as such for faithful genetic inheritance.

Overexpression of enzymes that repair endogenous damage to DNA [PDF]

European Journal of Biochemistry, 2000
A significant contribution to human mutagenesis and carcinogenesis may come from DNA damage of endogenous, rather than exogenous, origin. Efficient repair mechanisms have evolved to cope with this. The main repair pathway involved in repair of endogenous damage is DNA base excision repair.

Discerning protein pools by selective staining with self‐labeling tags

FEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.

Inhibitors of the DNA repair enzyme AAG

, 2022
DNA, the genetic blueprint of life, is targeted by a multitude of damaging species of both internal and external origin. This damage can result in the loss of genomic integrity and increase susceptibility to immunodeficiency, neurological disorders, and cancers.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

No cancer predisposition or increased spontaneous mutation frequencies in NEIL DNA glycosylases-deficient mice

Scientific Reports, 2017
Base excision repair (BER) is a major pathway for removal of DNA base lesions and maintenance of genomic stability, which is essential in cancer prevention. DNA glycosylases recognize and remove specific lesions in the first step of BER. The existence of

Epigenetic reprogramming of lineage switching in cancer

FEBS Letters, EarlyView.
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using

SIRT1 Enhances the Survival of Human Embryonic Stem Cells by Promoting DNA Repair

Stem Cell Reports, 2017
Summary: Human embryonic stem cells (hESCs) hold great promise for the treatment of many incurable diseases. Sirtuin1 (SIRT1), a class III histone deacetylase, is abundantly expressed in hESCs and is known to regulate early differentiation and telomere ...

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.
