DNA News and Research

RSS

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 zebrafish model could help advance glioblastoma multiforme research

Scientists at the Fralin Biomedical Research Institute at VTC have identified a new zebrafish model that could help advance glioblastoma multiforme research. Glioblastoma is an aggressive form of primary brain tumor - fewer than one in 20 patients survive five years after diagnosis.

Major antioxidant in green tea may increase levels of natural anti-cancer protein

An antioxidant found in green tea may increase levels of p53, a natural anti-cancer protein, known as the "guardian of the genome" for its ability to repair DNA damage or destroy cancerous cells.

Novel finding could lead to better treatments for Type 1 and Type 2 diabetes

Monash University researchers have uncovered the barrier to β-cell (beta cell) regeneration that could pave the way for improved treatments for diabetes and diseases that involve organ and tissue damage.

Study offers new protocols for high-quality SARS-CoV-2 genomic sequencing

Researchers at the Southern Illinois University, U.S.A. have presented a comprehensive and well-validated set of working protocols for sequencing high-quality SARS-CoV-2 genomes in high throughput from patient samples.

Disrupting cancer cell cycle with two commercially available inhibitors causes tumor cell death

With two commercially available inhibitors, the cell cycle of the cancer cells in the childhood tumor neuroblastoma can be disrupted at a key point causing tumor cell death.

A brain enzyme plays an important role in waking up neural stem cells

Researchers studying an enzyme in fruit fly larvae have found that it plays an important role in waking up brain stem cells from their dormant 'quiescent' state, enabling them to proliferate and generate new neurons.

Study reveals detailed map of glioblastoma in genetic, molecular detail

Glioblastoma is among the most aggressive and devastating of cancers. While rare compared with other cancers, it's the most common type of brain cancer.

Study addresses multiple challenges of the pathogenesis of Huntington's disease

Recent genetic data from patients with Huntington's disease (HD) show that DNA repair is an important factor that determines how early or late the disease occurs in individuals who carry the expanded CAG repeat in the HTT gene that causes HD.

Lifestyle changes in pregnant women linked to epigenetic alterations in babies

A study led by researchers at Lund University in Sweden showed a connection between lifestyle intervention in pregnant women with obesity and epigenetic alterations in the baby. The study is published in the journal Diabetes.

STING activation may be a new approach to reduce graft-versus-host disease

MUSC Hollings Cancer Center researcher Yongxia Wu, Ph.D., identified a new target molecule in the fight against graft-versus-host disease (GVHD).

Researchers discover previously-unknown function in enzyme critical for cancer growth

Considered the most lethal form of DNA damage, double-strand breaks must be repaired to prevent cell death. In developing therapies for hard-to-treat breast and ovarian cancers in patients with BRCA gene mutations, scientists aim to identify ways to keep cancer cells from using DNA break repair pathways.
