DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

New technique to detect gene doping in human plasma

All athletes wish to be at the top of their game while competing, yet some turn to corrupt strategies to achieve peak speed, agility, and muscle growth. Latest advancements in gene editing technology could lure athletes to change their DNA to gain an upper hand.

Study addresses mystery of how chromosomes are inherited during cell division

Starting as a single cell, organisms undergo millions of generations of divisions to ultimately generate the bones, heart, brain and other components that make up a living being. The mainspring within this intricate process is the transfer of DNA through each subsequent cell split within discrete packets called chromosomes.

DNA-editing technique used to extend lifespan of mice with progeria

Researchers have successfully used a DNA-editing technique to extend the lifespan of mice with the genetic variation associated with progeria, a rare genetic disease that causes extreme premature aging in children and can significantly shorten their life expectancy.

Scientists resolve long-standing debate over key mechanism involved in gene silencing

Scientists from Massachusetts General Hospital (MGH) have resolved a long-standing debate over how crucial gene-silencing protein detects its targets.

New project on self-deleting gene technology takes aim at mosquito populations

To control mosquito populations and prevent them from transmitting diseases such as malaria, many researchers are pursuing strategies in mosquito genetic engineering. A new Texas A&M AgriLife Research project aims to enable temporary "test runs" of proposed genetic changes in mosquitoes, after which the changes remove themselves from the mosquitoes' genetic code.

Controlling biological functions of DNA with the aid of light

DNA (deoxyribonucleic acid) is the basis of life on earth. The function of DNA is to store all the genetic information, which an organism needs to develop, function and reproduce. It is essentially a biological instruction manual found in every cell.

Chromosomal instability is associated with cancer's aggressiveness

Cancer cells are known for spreading genetic chaos. As cancer cells divide, DNA segments and even whole chromosomes can be duplicated, mutated, or lost altogether.

HKU researchers develop new drug discovery strategy targeting membrane proteins on live cells

A research team led by Dr Xiaoyu LI from the Research Division for Chemistry, Faculty of Science, in collaboration with Professor Yizhou LI from School of Pharmaceutical Sciences, Chongqing University and Professor Yan CAO from School of Pharmacy, Second Military Medical University in Shanghai has developed a new drug discovery method targeting membrane proteins on live cells.

Triple drug combination keeps people with metastatic colon cancer disease free for longer time

Researchers from SWOG Cancer Research Network, a cancer clinical trials group funded by the National Cancer Institute (NCI), part of the National Institutes of Health, have shown that a triple drug combination - of irinotecan, cetuximab, and vemurafenib - is a more powerful tumor fighter and keeps people with metastatic colon cancer disease free for a significantly longer period of time compared with patients treated with irinotecan and cetuximab.

Transporter protein likely played a crucial role in vertebrate evolution

A transporter protein that regulates cell membrane cholesterol likely played an important role in vertebrate evolution, according to a review published by iCeMS researchers in the journal FEBS Letters.

Study uncovers how shattered chromosomes make cancer cells more aggressive

Cancer is one of the world's greatest health afflictions because, unlike some diseases, it is a moving target, constantly evolving to evade and resist treatment.

Researchers report a potential cancer drug that targets mitochondrial function

A newly developed compound starves cancer cells by attacking their "power plants" - the so-called mitochondria. The new compound prevents the genetic information within mitochondria from being read.

Scientists discover molecular defects associated with rare genetic disorder in children

Damien D'Amours and his team at the Ottawa Institute of Systems Biology needed three years to discover the molecular defects associated with the LIC Syndrome, a serious genetic disorder that affects young children and result in acute respiratory distress, immune deficiency and abnormal chromosomes.

Scientists find master switch that adjusts gene activity to match nutrient levels in roundworms

Transforming a fertilized egg into a fully functional adult is a complicated task. Cells must divide, move, and mature at specific times. Developmental genes control that process, turning on and off in a choreographed way.

New computational tool can segment and analyze cell images of C. elegans

A joint research team co-led by City University of Hong Kong (CityU) has developed a novel computational tool that can reconstruct and visualise three-dimensional (3D) shapes and temporal changes of cells, speeding up the analysing process from hundreds of hours by hand to a few hours by the computer.

Scientists identify new protein that may improve future chemotherapy treatment

Chemotherapy not only attacks cancer cells but also targets all cells in the human body. This is the reason why patients receiving this treatment generally experience adverse side effects, like hair loss, physical weakness, and nausea.
