Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 17, one copy inherited from each parent, form one of the pairs. Chromosome 17 spans about 79 million base pairs (the building blocks of DNA) and represents between 2.5 percent and 3 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 17 likely contains between 1,200 and 1,500 genes.
Genes on chromosome 17 are among the estimated 20,000 to 25,000 total genes in the human genome.
Researchers utilized a CRISPR/Cas9 system to evaluate the usage of tRNA by deleting two tRNA genes from the genomes of hyper hepatocellular carcinoma and human near-haploid chronic myeloid leukemia cells.
A recent study by researchers from Sweden and the United Kingdom shows that CRISPR/Cas9-based genomic engineering can prompt unwanted on-target effects, and highlights the complexity of human DNA repair mechanisms in the presence of the powerful prokaryotic Cas9 nuclease. The paper is currently available on the bioRxiv* preprint server.
It turns out that not all build-ups of tau protein are bad, and a team of researchers from the Perelman School of Medicine at the University of Pennsylvania developed a method to show that.
Researchers at Henry Ford Health System, as part of a national asthma collaborative, have identified a gene variant associated with childhood asthma that underscores the importance of including diverse patient populations in research studies.
Researchers have used insight from a comprehensive genomic analysis of neuroblastoma to learn about the process driving one of the most common childhood solid tumors. The findings revealed possible approaches for developing precision medicines to improve patient outcomes. St. Jude Children's Research Hospital scientists led the study, which appears today in the journal Nature Communications.
The study, published in the scientific journal Nature, has uncovered a genetic vulnerability present in nearly 10% percent of all breast cancers tumours, and found a way to target this vulnerability and selectively kill cancer cells.
There are several studies looking at the effects of alcohol intake on the brain. Anew study adds to the existing knowledge. The large study with around 11,651 participants from United Kingdom shows that each gram of alcohol consumed could lead to around a week of aging of the brain.
The search for a mechanism that could explain how the protein complex NCOR1/2 regulates memory has revealed an unexpected connection between the lateral hypothalamus and the hippocampus, the feeding and the memory centers of the brain, respectively.
Researchers have discovered that the same gene which increases your risk of depression following financial stress as you grow older also reduces your chance of depression associated with friendship and relationships stresses when young- your social network.
How are chromosomes arranged in the cell nucleus? Is it possible that they communicate with one another by "touching" each other?
Some scientists have suspected that the most common form of ovarian cancer may originate in the fallopian tubes, the thin fibrous tunnels that connect the ovaries to the uterus.
Research led by scientists at UC San Francisco and Case Western Reserve University School of Medicine has used brain "organoids" — tiny 3D models of human organs that scientists grow in a dish to study disease — to identify root causes of Miller-Dieker Syndrome (MDS), a rare genetic disorder that causes fatal brain malformations.
All humans are 99.9 percent identical, genetically speaking. But that tiny 0.1 percent variation has big consequences, influencing the color of your eyes, the span of your hips, your risk of getting sick and in some ways even your earning potential.
Kataegis is a recently discovered phenomenon in which multiple mutations cluster in a few hotspots in a genome. The anomaly was previously found in some cancers, but it has been unclear what role kataegis plays in tumor development and patient outcomes.
AbbVie, a global biopharmaceutical company, today announced The Lancet Oncology published results from the Phase 2, single arm, open label trial studying venetoclax in patients with relapsed/refractory (R/R) chronic lymphocytic leukaemia (CLL) with 17p deletion.
A major challenge in the field of neurodegeneration is the unclear understanding of neuronal dysfunction. Elucidation of these patho-mechanisms could result in the identification of novel therapeutic targets. In this article, Bell et al. present an exhaustive literature review highlighting the endoplasmic reticulum (ER) kinase PERK as a crucial contributor to systemic and neurodegenerative disorders.
Using the genetic information of two different families with three generations of disease, researchers have identified a new mutation responsible for a degenerative and ultimately fatal movement disorder. Through induced pluripotent stem cell techniques, researchers also grew neurons from one patient in the laboratory to be used in future experiments.
The effect of a widespread genetic variant that increases the risk for childhood asthma can be neutralized. A new study shows that young infants are particularly responsive to the positive influence of exposure to farm dust.
New research published in The Lancet Respiratory Medicine and presented at this year's European Respiratory Society meeting in Amsterdam presents the first analyses of genetic data from the UK Biobank that reveal new associations with lung disease and smoking behaviour.
AbbVie, a global biopharmaceutical company, today announced that a Phase 2 trial of its investigational medicine venetoclax met its primary endpoint of achieving overall response rates in patients with relapsed/refractory or previously untreated chronic lymphocytic leukemia (CLL) with 17p deletion, according to an independent review analysis.
