Maui Fires: How Mitochondrial DNA Will Identify Human Remains

PLOS: DNA Science

The Maui firestorm was so vast and fast that most identification of human remains will come from bits of persisting DNA from mitochondria. MtDNA in Forensics and Genealogy Mitochondrial DNA (mtDNA) is used in forensics to match the tiniest bits of human remains to families. Mitochondrial DNA is also far more abundant than nuclear DNA.

More diverse datasets lead to better genetic risk prediction for heart disease

Broad Institute

The accuracy of these scores has improved for some diseases and groups of people, but they continue to fall short for those of non-European ancestry, mainly because the genetic datasets used to calculate these scores have largely come from people of European ancestry.

Addressing increasingly resistant drugs by infectious agents

Drug Target Review

There have been several studies that have reported the ability of infectious disease agents to be drug resistant. Infectious agent includes bacteria, virus, fungi, and parasites, and they are capable of causing disease in a living organism. They could be spread by physical contact, airborne, waterborne, foodborne, or vector-borne.

Epigenetic editing: the next generation of genetic medicine

Drug Target Review

The reasons for this are multifaceted, including concerns over the safety of directly altering DNA sequences and subsequent regulatory restrictions that have arisen as a result. The epigenome (meaning ‘above the genome’) is a system of reversible marks regulating how the DNA is read, translated and used. What is epigenetic editing?

Precision medicine: exploring the impact of DNA Testing

Drug Target Review

Clinical trials are now underway for various genetic subtypes of both rare and common diseases, on the understanding that medications utilising genetic biomarkers have a significantly higher chance of success. There are clinical trials underway for genetic subtypes of rare and common diseases.

Older Siblings Made Possible Just-Approved Gene Therapy for Metachromatic Leukodystrophy

PLOS: DNA Science

Lenmeldy adds functional genes that encode the enzyme arylsulfatase A (ARSA) to bone marrow stem cells taken from children who have inherited the disease, but haven’t yet developed symptoms, which typically begin around age 2 or 3. Each of their children would face a 1 in 4 chance of inheriting the disease.

Human organoid research offers insights into gut cell differentiation

Drug Target Review

The findings may have implications for our understanding of gastrointestinal diseases and endocrine disorders, as well as pancreatic development and diabetes. Gene regulation The differentiation of stem cells into specific cell types happens by gene regulation, where genes in the DNA of cells are switched ‘on’ and ‘off’.
