Mammalian SWI/SNF chromatin remodeling complexes and cancer: Mechanistic insights gained from human genomics

Science Advances, 2015
New human genetic findings paired with biochemical studies are challenging current thinking on the function of chromatin remodeling complexes. Over the past 4 years, nearly 100 exome sequencing studies have revealed the high frequency of mutations in the

Identifying transcription factors controlling the basal expression of human MRP4 highlights a substantial role for Sp1

FEBS Open Bio, EarlyView.
The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Proof of principle for shotgun DNA mapping by unzipping

, 2009
Ability to map polymerases and nucleosomes on chromatin is important for understanding the impact of chromatin remodeling on key cellular processes. Current methods (such as ChIP and ChIP-chip) have produced a wealth of information that demonstrates ...

The Chromosomal High-Affinity Binding Sites for the Drosophila Dosage Compensation Complex [PDF]

, 2008
Dosage compensation in male Drosophila relies on the X chromosome-specific recruitment of a chromatin-modifying machinery, the dosage compensation complex (DCC). The principles that assure selective targeting of the DCC are unknown.

Aging Is a Key Driver for Adult Acute Myeloid Leukemia

Aging and Cancer, EarlyView.
Acute myeloid leukemia (AML) is a classical age‐related hematologic malignancy, and a key driver of AML is aging, which profoundly regulates intrinsic factors such as genomic instability, epigenetic reprogramming, and metabolic dysregulation, and alters bone marrow microenvironment.

Nuclear factor I genomic binding associates with chromatin boundaries [PDF]

, 2013
BACKGROUND: The Nuclear Factor I (NFI) family of DNA binding proteins (also called CCAAT box transcription factors or CTF) is involved in both DNA replication and gene expression regulation.

CREMOFAC - a database of chromatin remodeling factors [PDF]

, 2006
Motivation: Chromatin-remodeling is an important event in the eukaryotic nucleus rendering nucleosomal DNA accessible for various transaction processes. Remodeling Factors facilitate the dynamic nature of chromatin through participation of the collective

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance

Aging and Cancer, EarlyView.
NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

Chromatin Modification and Remodeling in Heart Development

The Scientific World Journal, 2006
In organogenesis, cell types are specified from determined precursors as morphogenetic patterning takes place. These events are largely controlled by tissue-specific transcription factors.
