Researchers have created a comprehensive map of the DNA sequences that control gene expression in human cells, identifying 2.37 million potential regulatory elements. This registry reveals previously unrecognized classes of elements and illuminates how noncoding genetic variation contributes to cell type-specific traits.
Biologists at Cold Spring Harbor Laboratory have made a significant discovery that could lead to better patient outcomes for ER+ breast cancer patients. Inhibiting the BPTF protein in mice can slow cancer metastasis and restore tumors' susceptibility to hormone therapy, offering new hope for treating resistant forms of the disease.
A new method called DynaTag has been developed for mapping protein binding to DNA, providing high-resolution results. This innovation enables the analysis of single cells across various tissues and enhances understanding of developmental biological processes and disease mechanisms.
Researchers discovered 47,350 active putative enhancers associated with Parkinson's disease, schizophrenia, and other neurological disorders. These enhancers were found to regulate gene expression during neuronal differentiation.
A team of researchers at Tokyo Medical and Dental University has identified a gene called Rasip1 as crucial for blood cell development. SOX17, a transcription factor, is found to activate Rasip1, leading to the formation of hematopoietic stem cells and associated hematopoietic activity.
Researchers at St. Jude Children's Research Hospital discovered that the epigenetic landscape plays a crucial role in regulating pioneer transcription factor binding. By understanding this process, scientists can develop new therapeutics to combat cancer and other diseases. The study reveals how epigenetic modifications affect transcri...
Researchers at the University of Alabama at Birmingham have identified TBX20 as a vital regulator of direct human cardiac reprogramming. Adding TBX20 to existing cocktails improves contractility and mitochondrial function in reprogrammed heart muscle cells, suggesting a therapeutic potential for TBX20.
John Barrows, a postdoctoral researcher at Kennesaw State University, has earned a two-year NSF Postdoctoral Research Fellowship grant worth $138,000 to study DNA-binding proteins within bacteria. The funding will enable further research and mentoring of undergraduates in the lab.
A research group at the University of Helsinki has discovered the logic controlling gene regulation in human cells. They found that individual transcription factors contribute to gene regulation in an additive manner and identified regulatory elements that function within closed chromatin regions.
A comprehensive study has revealed over 7,000 human transcription factor (TF) protein-protein interactions, with most playing important roles in transcriptional regulation. The study identifies groups of TFs with specific biological functions, such as chromatin remodelling and RNA splicing.
Researchers found that Atf1 and Rst2 transcription factors reciprocally bind to DNA in fission yeast cells responding to glucose scarcity. This unique mechanism prevents both proteins from binding alone and integrates independent activation pathways.
Scientists have used super-resolution microscopy to identify physical connections between five human chromosomes, revealing a shared sequence encoding ribosomal DNA that holds the chromosomes together. The findings suggest that these inter-chromosomal linkages are pervasive in healthy and diseased tissue, and may play a role in chromos...
The new ultra-low input CUT&RUN (uliCUT&RUN) technique allows for genome-wide mapping of DNA binding proteins from single cells and individual pre-implantation mouse embryos. This enables researchers to focus on cell heterogeneity and studies from limited biological samples.
Researchers developed a high-throughput method to screen and categorize transcription factors based on their ability to displace nucleosomes. The study identified both new and previously known nucleosome-displacing factors, which tend to be highly abundant in the nucleus and bind tightly to DNA.
Researchers at Stowers Institute for Medical Research developed a new method to precisely map individual transcription factor binding sites in the genome. The technique, called ChIP-nexus, uses an enzyme to trim back DNA fragments to the spot where transcription factors bind, providing more accurate information than existing methods.
Researchers discovered that transcription factor binding sites are not conserved across 300 million years of evolution. Despite this, these proteins still regulate liver-specific genes in vertebrates. This study highlights the plasticity of gene regulation and its implications for disease mechanisms.
A recent study found that many interactions detected by ChIP-chip are functionally irrelevant. The researchers discovered a clear relationship between the number of factor molecules bound at a given site and its role in gene regulation, suggesting that DNA sites with low-level binding may play no role in regulating gene expression.
Researchers identified a large fraction of functional transcription factor binding sites near human gene transcriptions, challenging traditional views of complex organism regulation. This discovery could aid in identifying transcriptional networks underlying cellular processes and diseases.
STAT proteins play a key role in regulating gene expression by phosphorylating specific sequences, leading to transcriptional activation. This process is essential for various cellular processes, including proliferation and differentiation.
