Organisms are made up of cells, and in each of those cells, a genome encodes the instructions for that organism to grow and survive. The human genome has at least 20,000 genes, and the expression of ...
Enhancer–promoter specificity in gene transcription: molecular mechanisms and disease associations
Although often located at a distance from their target gene promoters, enhancers are the primary genomic determinants of temporal and spatial transcriptional specificity in metazoans. Since the ...
The development of the human face is a highly complex morphogenetic process. It requires the precise formation of dozens of intricate structures to enable the full ...
Duke University Medical Center-led research has identified a human-specific DNA enhancer that regulates neural progenitor proliferation and cortical size. Small genetic changes in HARE5 amplify a key ...
In a study published in Genome Research, a team of researchers, including Cornell College Assistant Professor of Biology Sophie Gillett, looked at regions of human genetic code that are known for ...
A multi-institutional team of researchers led by Case Western Reserve University has identified a pattern of clustered genetic changes that appear to encourage growth of colorectal cancer tumors—a ...
The mammalian cortex, the region of the brain responsible for a wide range of higher-level cognitive functions, including sensory perception, motor control, and complex thought, is composed of a ...
A newly developed method called ReapTEC allowed the discovery of thousands of active bidirectional enhancers. Further analysis of GWAS data revealed that various immune-mediated diseases, like ...
DNA transcription is the vital first step needed for switching on our genes. For a gene to be switched on, it must be acted upon by an enzyme called RNA polymerase. This is a molecular machine which ...
Scientists can now predict which single-letter changes to the DNA within our genomes will alter genetic instructions and disrupt development, leading to changes such as the growth of extra digits and ...
Genetic studies of diseases map segments of the genome driving disease. But to understand how those changes contribute to disease progression, it is important to understand how they may alter gene ...
