New research has identified a possible reason why men are more susceptible to cancer than women. The work published in the Journal of the National Cancer Institute reports that the loss of function in certain genes of the sex-determining Y chromosome may play a role in this.
A new discovery by a Japanese team has identified a type of microorganism called an Asgard archaeon, which could shed light on how early eukaryotic cells evolved. The project took 12 years after finding the cells in deep-sea mud. The findings of the closest Archaeal relative to eukaryotes cultures so far will allow further detailed cellular and metabolic investigation and find out more about the origins of complex life.
Researchers at Carnegie Institution for Science, USA have discovered a mechanism in which the body tries to eliminate egg cells of the poorest quality. The findings indicate that this elimination during foetal development is related to a transposable element, or “jumping gene”, called LINE-1 that promotes the survival of eggs with more “jumping gene” activity.
A team of international researchers have conducted a genome-wide association study (GWAS) to identify genes responsible for high population-levels of alcohol consumption. They used genomic data from the UK Biobank and a US study to pinpoint the genes responsible, identifying six loci that could be associated with alcohol use disorder (AUD).
Bioengineers based in the US have designed a “DNA-binding editorial assistant” that will allow gene-editing technology, like CRISPR, to access previously inaccessible genes of interest. The new protein design can be used to open up areas of the DNA that are obscured by chromatin, which would improve CRISPR efficiency and aid in developing more precise gene-editing techniques to combat disease.
Dr Gemma Chandratillake is the Education and Training Lead for the East Midlands and East of England NHS Genomic Laboratory Hub. She is passionate about the potential of genomics to improve healthcare, and works creatively to facilitate the mainstreaming of genomics within the NHS. We managed to have a chat with Gemma ahead of her […]
Researchers from the Cold Spring Harbor Laboratory (CSHL) and Memorial Sloan Kettering Cancer Center (MSK) have discovered that Acute Myeloid Leukaemia (AML) grows by taking advantage of the B6 vitamin to accelerate cell division. The findings could pave the way for a treatment that can stop cancer growth by manipulating the enzyme that pushes B6 to make proteins essential for cell division.
A genetic variant associated with poor response to a common asthma treatment has been identified in a new study by the Cleveland Clinic. The research team found that a particular gene variant was present in asthmatic patients who were less likely to respond to glucocorticoids and often develop severe asthma.
An international team of researchers has assembled a human genome using just the remnants of a piece of birch tar—last chewed some 5,700 years ago. Scientists have pieced together quite a bit about the person’s life using DNA left in the tar, learning about everything from her diet to certain diseases she carried.
Dozens of rare DNA variants have been identified in the largest genetic study of human height in an Asian population. The genome-wide association study (GWAS) highlighted some of the similarities and differences that play a role in determining height in different parts of the world.
A research team from Lewis Katz School of Medicine at Temple University (LKSOM) and Fox Chase Cancer Centre found that in prostate cancer, a mutation leading to the loss of just one allele of a tumour suppressor gene known as PPP2R2A is enough to make a tumour caused by other mutations worse.
A genome-wide analysis of nearly 200,000 military veterans has identified six genetic variants linked to anxiety. This is the largest genome-wide association study (GWAS) to date, and has given insights into how people may be pre-disposed to anxiety disorders and provides further explanations for why anxiety and depression often coexist.
Dr Rona Strawbridge has been using genetics to try to understand complex diseases, who’s work has focused much on obesity, type 2 diabetes and cardiovascular disease, and more recently serious mental illness. We managed to have a chat with Rona ahead of her speaking at the Festival of Genomics about her work and why she’s excited to be speaking at the festival this year.
Researchers at the Seattle Children’s Hospital in Washington have identified variants in the ZNF292 gene that could contribute to the development of autism. The study built upon previous work that linked the ZNF292 gene to intellectual disability, and has now identified multiple variations in the gene that could be responsible.
A collaborative fine-mapping study from researchers across more than 450 departments worldwide has found five times more genetic variants to be associated with breast cancer than previously thought. The most comprehensive map of breast cancer risk variants to date identified 352 DNA errors that are associated with breast cancer with “reasonable confidence”, and target 191 genes, five times more than were previously recognised.
