Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 8, one copy inherited from each parent, form one of the pairs. Chromosome 8 spans about 146 million DNA building blocks (base pairs) and represents between 4.5 percent and 5 percent of the total DNA in cells.
Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 8 likely contains between 700 and 1,100 genes.
Genes on chromosome 8 are among the estimated 20,000 to 25,000 total genes in the human genome.
Type 2 diabetes mellitus (T2DM) is a highly prevalent metabolic disorder worldwide. Beyond glucose dysregulation, it exerts significant effects on the central nervous system.
New research published in Allergy indicates that certain environmental exposures may affect a child's risk of developing atopic eczema, a condition characterized by dry, itchy, and inflamed skin. In other words, although some people may be genetically predisposed to eczema, certain environmental factors may increase or decrease that risk.
A study initiated by a University of Arizona Comprehensive Cancer Center physician-scientist defined for the first time how loss of the Y chromosome in male immune cells negatively affects immune system function, which may explain why loss of Y is associated with lower cancer survival rates.
When cancer cells in male patients and immune cells in their tumors both lose the Y chromosome, those patients tend to experience poorer outcomes than patients without Y chromosome loss, according to new findings from Cedars-Sinai investigators.
Cannabis has been a globally important crop for millennia. While best known today as marijuana for its psychoactive cannabinoid THC (tetrahydrocannabinol), historically, cannabis has been a cornerstone of human civilization, providing seed oil, textiles, and food for more than 10,000 years.
Human healthy aging and longevity are complex phenomena influenced by a dynamic interplay of genetic, epigenetic, metabolic, immune, and environmental factors.
Results from the VITAL randomized controlled trial reveal that vitamin D supplementation helps maintain telomeres, protective caps at the ends of chromosomes that shorten during aging and are linked to the development of certain diseases.
In a comprehensive Genomic Press Invited Expert Review, researchers from the University of Haifa have synthesized cutting-edge findings on Prader-Willi syndrome (PWS), revealing how this complex neurodevelopmental disorder serves as a critical model for understanding the interplay between autism spectrum disorder (ASD) and psychotic spectrum disorders (PSD).
Ask scientists what gene editing tool is most needed to advance gene therapy, and they'd probably describe a system that's now close to realization in the labs of Samuel Sternberg at Columbia University Vagelos College of Physicians and Surgeons and David Liu at the Broad Institute of MIT and Harvard.
Since the human genome was first sequenced in 2003, the world's scientific community has been racing to decipher this "book" written in an alphabet of four letters.
Researchers identified 11 genetic loci linked to the age at which infants start walking, revealing that this milestone is influenced by thousands of common genetic variants. These genetic factors also correlate with brain development, cognitive traits, and neurodevelopmental conditions like ADHD.
Medulloblastoma is one of the most common malignant tumors of the central nervous system (CNS) in children and adolescents. It develops in the area of the cerebellum, which is responsible for movement coordination, among other things.
Study provides new evidence that sensory stimulation of gamma-frequency brain rhythm may promote broad-based restorative neurological health response.
New data published in The Journal of Immunology uncovered the role of Plasmodium falciparum infection (malaria) in the development of Burkitt lymphoma (BL), the most common childhood cancer in equatorial Africa and New Guinea.
Antibiotic resistance is a serious threat to public health. When antibiotics don't work, we risk not being able to treat many types of infections and people who would previously have been cured, can die.
Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin.
The research team discovered that glassware used to manipulate and culture fertilized eggs in the fields of assisted reproductive technology (ART), livestock farming, and basic research contains toxic substances that interfere with the development of fertilized eggs (embryos).
A new study from Weill Cornell Medicine provides insights into how cells maintain the tiny end caps of chromosomes as they divide, a key process in keeping cells healthy.
A seminal study from researchers at the Icahn School of Medicine at Mount Sinai and their collaborators in the United Kingdom, Belgium, Spain, the Netherlands, and Iceland has uncovered a new genetic cause of neurodevelopmental disorders (NDDs).
A new study has unveiled when chronic myeloid leukaemia, a type of cancer that affects the blood and bone marrow, arises in life and how fast it grows.
