Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS 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 ...

Unconventional metabolites in chromatin regulation

open access: yes, 2021
Chromatin, the complex of DNA and histone proteins, serves as a main integrator of cellular signals. Increasing evidence links cellular functional to chromatin state.

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Chromatin remodeling enzyme Brg1 is required for mouse lens fiber cell terminal differentiation and its denucleation [PDF]

open access: yes, 2010
Background: Brahma-related gene 1 (Brg1, also known as Smarca4 and Snf2 beta) encodes an adenosine-5'-triphosphate (ATP)-dependent catalytical subunit of the (switch/sucrose nonfermentable) (SWI/SNF) chromatin remodeling complexes.

Insulator-based loops mediate the spreading of H3K27me3 over distant micro-domains repressing euchromatin genes

open access: yesGenome Biology, 2020
Background Chromosomes are subdivided spatially to delimit long-range interactions into topologically associating domains (TADs). TADs are often flanked by chromatin insulators and transcription units that may participate in such demarcation. Remarkably,

Epigenetic reprogramming of lineage switching in cancer

open access: yesFEBS 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

DNA methylation in chromatin - complexes and mechanisms [PDF]

open access: yes, 2010
The DNA in the eukaryotic genome is packaged into chromatin whose basic repeating unit is the nucleosome consisting of 147bp of DNA wrapped around an octameric histone core.

Statins as anti‐tumor agents: A paradigm for repurposed drugs

open access: yesCancer Reports
Background Statins, frequently prescribed medications, work by inhibiting the rate‐limiting enzyme HMG‐CoA reductase (HMGCR) in the mevalonate pathway to reduce cholesterol levels.

KANSL3 directs transcriptional programs essential for hepatic metabolism and differentiation

open access: yesLife Science Alliance
KANSL3 is an epigenetic regulator of hepatocyte metabolism and differentiation, essential for liver development and key to maintaining liver health. Liver disease is a leading cause of mortality worldwide.

Cantharidin downregulates PSD1 expression and inhibits autophagic flux in yeast cells

open access: yesFEBS Open Bio, 2022
Cantharidin is a terpenoid compound of insect origin, naturally produced by male blister beetles as an antipredatory mechanism. Cantharidin has anticancer properties, which are attributed to its ability to induce cell cycle arrest, DNA damage, MAPK ...
