Increased Cancer Risk in Men due to Loss of Function of Y-Chromosome

17 January 2020

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.

New Archaeal Organism Found Gives Insights into Early Complex Life

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.

Poor Quality Egg Cells are Threatened by Jumping Genes

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.

Six Loci Identified in Association with High Alcohol Intake

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).

Successfully Deleting Disease by Opening up DNA

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.

Leukaemia Cells are Addicted to Vitamin B6

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.

Genetic Variant Identified Associated with Poor Response to Asthma Treatment

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.

Rare DNA Variants Linked to Height Found In Japanese Study

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.

Can Sestrin Actually Mimic the Effects of Exercise?

Researchers at Michigan Medicine have found that a naturally occurring protein called Sestrin can mimic many effects of exercise in flies and mice. Published in Nature Communications, understanding the function of this protein could help scientists combat muscle wasting due to aging and other causes.

Prostate Cancers Show Common Genetic Defect, Inspiring New Anti-Cancer Drugs

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.

GWAS Finds Six Genetic Variants Linked to Anxiety in Veterans

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.

Gene Variants Linked to Developing Features of Autism

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.

Alzheimer’s Protein may Increase in Levels After Just One Bad Night of Sleep

A preliminary study by researchers at Uppsala University, Sweden has found that losing just one night of sleep may increase levels of tau – a biomarker for Alzheimer’s disease. This study found levels of tau were increased in the blood of young, healthy men who were deprived of just one night of sleep, and could contribute to developing the disease later in life

Five Times More Genes Than Previously Thought Found to be Linked to Breast Cancer

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.
