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).

Scientists use gene-editing technique to considerably increase the production of formicamycin antibiotics

Researchers have leveraged gene-editing advances to obtain a 10 times increase in the development of super-bug targeting formicamycin antibiotics.

Circadian rhythms control killer cells in the immune system

According to an analysis of data humans’ ability to combat diseases may largely depend on day-to-day circadian cycles than previously believed.

Study reveals richness of space-time gene expression dynamics of the liver

Nothing in biology is static. Biological processes fluctuate over time, and if we are to put together an accurate picture of cells, tissues, organs etc., we have to take into account their temporal patterns. In fact, this effort has given rise to an entire field of study known as "chronobiology".

New discovery helps explain how COVID-19 suppresses the body’s immune response

Seeking to understand why COVID-19 is able to suppress the body's immune response, new research from the USC Leonard Davis School of Gerontology suggests that mitochondria are one of the first lines of defense against COVID-19 and identifies key differences in how SARS-CoV-2, the virus that causes COVID-19, interacts with mitochondrial genes when compared to other viruses.

Using proteomics to determine how long a corpse has been underwater

In this interview, AZoLifeSciences speaks to Dr. Noemi Procopio about her latest research which involved using bone proteomics to determine the length of time a corpse had been left underwater.

Sequencing-based solution can help determine patients’ response to infection therapy

Scientists from the University of Helsinki have created a new sequencing-based strategy for identifying pathogens from complex samples.

Scientists trace back evolutionary history of antibiotic resistance genes

By comparing thousands of bacterial genomes, scientists in Gothenburg, Sweden have traced back the evolutionary history of antibiotic resistance genes. In almost all cases where an origin could be determined, the gene started to spread from bacteria that, themselves, can cause disease.

New deep neural network predicts transcription factors from protein sequences

A collaborative team of researchers have developed a deep neural network called DeepTFactor that predicts transcription factors from protein sequences.

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.
