ModHMM: A Modular Supra-Bayesian Genome Segmentation Method [PDF]

open access: yes, 2020
Genome segmentation methods are powerful tools to obtain cell type or tissue-specific genome-wide annotations and are frequently used to discover regulatory elements.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Epithelial cells maintain memory of prior infection with Streptococcus pneumoniae through di-methylation of histone H3

open access: yesNature Communications
Epithelial cells are the first point of contact for bacteria entering the respiratory tract. Streptococcus pneumoniae is an obligate human pathobiont of the nasal mucosa, carried asymptomatically but also the cause of severe pneumoniae.

Opening Chromatin [PDF]

open access: yesMolecular Cell, 2002
How the transcriptional apparatus gains access to and subsequently opens compacted chromatin has remained a mystery. Now in this issue of Molecular Cell, Zaret and coworkers show that chromatin opening in vitro is not mediated by the classical chromatin remodeling machines but instead occurs through specific transcription factor-histone interactions.

Chromatin Structure in the Cellular Slime Mold Dictyostelium discoideum [PDF]

open access: yes, 1978
The structure of Dictyostelium discoideum chromatin has been studied by the following techniques: electron microscopy, staphylococcal nuclease digestion, acrylamide gel electrophoresis, sucrose gradient centrifugation, and melting.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Structural basis of cyclobutane pyrimidine dimer recognition by UV-DDB in the nucleosome

open access: yesNature Communications
In mammalian global genomic nucleotide excision repair, UV-DDB plays a central role in recognizing DNA lesions, such as 6-4 photoproducts and cyclobutane pyrimidine dimers, within chromatin.

Tumorigenic Cell Reprogramming and Cancer Plasticity: Interplay between Signaling, Microenvironment, and Epigenetics

open access: yesStem Cells International, 2018
Accumulating evidences indicate that many tumors rely on subpopulations of cancer stem cells (CSCs) with the ability to propagate malignant clones indefinitely and to produce an overt cancer.

DDK/Hsk1 phosphorylates and targets fission yeast histone deacetylase Hst4 for degradation to stabilize stalled DNA replication forks

open access: yeseLife, 2021
In eukaryotes, paused replication forks are prone to collapse, which leads to genomic instability, a hallmark of cancer. Dbf4-dependent kinase (DDK)/Hsk1Cdc7 is a conserved replication initiator kinase with conflicting roles in replication stress ...

Chromatin Preparation and Chromatin Immuno-precipitation from Drosophila Embryos

open access: yes, 2016
This protocol provides specific details on how to perform Chromatin immunoprecipitation (ChIP) from Drosophila embryos. ChIP allows the matching of proteins or histone modifications to specific genomic regions.
