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).

Researchers develop α-emitting cancer therapy using a novel drug targeting LAT1

A cancer-specific L-type amino acid transporter 1 (LAT1) is highly expressed in cancer tissues.

New UCLA-developed device transfers mitochondria into 100,000 or more recipient cells

Scientists from the UCLA Jonsson Comprehensive Cancer Center have developed a simple, high-throughput method for transferring isolated mitochondria and their associated mitochondrial DNA into mammalian cells.

Scientists trace genetic roots of Chiari 1 malformation

About one in 100 children has a common brain disorder called Chiari 1 malformation, but most of the time such children grow up normally and no one suspects a problem.

Researchers discover how chromosomal instability allows cancer cells to avoid immune defenses

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. This is called chromosomal instability, and scientists at Memorial Sloan Kettering have learned that it is associated with cancer's aggressiveness.

Researchers develop new drug discovery method 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.

Study clarifies the effect of aging on hematopoietic stem cells

By transferring mouse aged hematopoietic stem cells (aged HSCs) to the environment of young mice (bone marrow niche), it was demonstrated that the pattern of stem cell gene expression was rejuvenated to that of young hematopoietic stem cells.

Study reveals how ecDNA fragments drive gene amplification to generate drug resistance in cancer

Researchers led by Ludwig San Diego Member Don Cleveland and Peter Campbell of the Sanger Center have solved the mystery of how free-floating circular DNA fragments, which are almost exclusively found in cancer cells, drive gene amplification to generate drug resistance in cancer.

Researchers discover 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.

23 Dec 2020

Researcher discovers seven DNA fingerprints that define cancer risk

Lifestyle, or put another way 'bad habits', is one of the textbook explanations for why some people are at higher risk for cancer.

Molecular reporters produce fluorescence to expose the allies of tumor cells

Glioblastoma is the most common malignant brain tumor in adults. Roughly five in every 100,000 people develop this type of cancer each year.

COVID-19 severity could be linked to genetic variance

A new study describes some potentially important genetic factors in the host that may shape the clinical symptoms and signs of the disease.

Novel computational tool can systematically analyze cell images in 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.

Researchers discover protein 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.

23 Dec 2020

Researchers uncover key regulation step that inhibits tumor growth

Most living things need oxygen to grow and thrive. Even cancerous tumors. That's why tumors will readily sprout new blood vessels if their oxygen is starved, creating new lifelines for survival.

22 Dec 2020

New drug starves cancer cells by attacking mitochondria

A newly developed compound starves cancer cells by attacking their "power plants" - the so-called mitochondria.

22 Dec 2020

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.

22 Dec 2020

Clinical psychologist evaluates the dangers of race-based norms in cognitive testing

A UCSF clinical psychologist has taken aim at the National Football League (NFL) for "race norming" black players diagnosed with dementia, a practice that is depriving them of the monetary awards allocated to former footballers with neurodegenerative disorders.
