Overview of molecular signatures of senescence and associated resources: pros and cons

open access: yesFEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Facultative dosage compensation of developmental genes on autosomes in Drosophila and mouse embryonic stem cells

open access: yesNature Communications, 2018
In Drosophila the Male-Specific Lethal complex (MSLc) mediates upregulation of the single male X chromosome. Here the authors provide evidence that MSL2 also targets autosomal genes required for proper development and that MSL2 binds and similarly ...

SIRT4 positively regulates autophagy via ULK1, but independently of HDAC6 and OPA1

open access: yesFEBS Open Bio, EarlyView.
Cells expressing SIRT4 (H161Y), a catalytically inactive mutant of the sirtuin SIRT4, fail to upregulate LC3B‐II and exhibit a reduced autophagic flux under stress conditions. Interestingly, SIRT4(H161Y) promotes phosphorylation of ULK1 at S638 and S758 that are associated with inhibition of autophagy initiation.

Acetylated histone variant H2A.Z is involved in the activation of neo-enhancers in prostate cancer

open access: yesNature Communications, 2017
Acetylation of the histone variant H2A.Z at gene promoters is associated with oncogene activation; however, it is unclear if such modification has a role in regulating the function of enhancers.

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

open access: yesFEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

Effect of Trust in Science on Parental Reactions to Messaging about Children’s Epigenetics-Related Obesity Risk

open access: yesPublic Health Genomics
Introduction: Accumulating evidence suggests that preconception epigenetic changes elevate the risk for obesity throughout the lifespan. Little is known about how parents may react to learning about parent-child epigenetic transmission of ...

SUMO conjugation – a mechanistic view

open access: yesBiomolecular Concepts, 2017
The regulation of protein fate by modification with the small ubiquitin-related modifier (SUMO) plays an essential and crucial role in most cellular pathways.

Epigenetics protocols

open access: yesEuropean Journal of Histochemistry, 2012
Thanks to the creative effort of Prof. Trygve O. Tollefsbol (Dept. of Biology, University of Alabama at Birmingham, USA) we can handle the second edition in just seven years of this must needed volume devoted to the study of the epigenome.

FGFR Like1 drives esophageal cancer progression via EMT, PI3K/Akt, and notch signalling: insights from clinical data and next‐generation sequencing analysis

open access: yesFEBS Open Bio, EarlyView.
Clinical analysis reveals significant dysregulation of FGFRL1 in esophageal cancer (EC) patients. RNAi‐coupled next‐generation sequencing (NGS) and in vitro study reveal FGFRL1‐mediated EC progression via EMT, PI3K/Akt, and Notch pathways. Functional assays confirm its role in tumor growth, migration, and invasion.
