Molecular Diagnostics

Image: In acute myeloid leukemia (AML), defective blood cells (stained purple) are present. When the cells have a double mutation of both the IDH2 and SRSF2 genes (bottom right), the number of defective cells rises considerably, indicating a more lethal disease (Photo courtesy of Cold Spring Harbor Laboratory).

Two Different Mutations Identified as Cause of AML

Two very different mutations have been identified as unexpected partners in crime for causing the blood cancer acute myeloid leukemia (AML). Expert analysis helped reveal how this deadly duo is far more common in AML than thought. More...

Image: A test to detect opioid drugs in exhaled breath was developed. In this photograph, a volunteer breathes normally into the human breath sampler. Samples are frozen before being taken to the laboratory for analysis (Photo courtesy of Dr. Cristina Davis, University of California, Davis).

Breath Analysis May Replace Blood Sampling to Monitor Drug Usage

A simple and non-invasive technique to collect exhaled breath condensate (EBC) from chronic pain patients was developed, and its usefulness was confirmed by comparing metabolites in breath and blood samples following use of different analgesic opioid drugs. More...

Stunted Microbiota and Opportunistic Pathogen Colonize C-Section Birth

Immediately after birth, newborn babies experience rapid colonization by microorganisms from their mothers and the surrounding environment. Infants born by Caesarean section have gut microbiomes that differ from those of infants born vaginally, carrying more hospital-associated opportunistic pathogens. More...

Parkinson’s Gene Mutation Linked to Higher Risk of Leukemia

Parkinson's disease is a progressive nervous system disorder that affects movement. Symptoms start gradually, sometimes starting with a barely noticeable tremor in just one hand. Tremors are common, but the disorder also commonly causes stiffness or slowing of movement. More...

Image: The association of genetic liability to psychotic experiences with neuropsychotic disorders and traits has been explored (Photo courtesy of Cardiff University).

Genetic Links Uncovered Between Psychotic Experiences

Psychotic experiences, such as hallucinations and delusions, are features of psychiatric disorders, such as schizophrenia, but they are also reported by approximately 5% to 10% of the general population. More...

Molecular Changes Associated with Treating Lymphatic Filariasis

Lymphatic filariasis (LF) is a disabling neglected tropical disease that is caused by the mosquito-borne filarial parasites Wuchereria bancrofti, Brugia malayi and B. timori. Adult worms live in the human host’s lymphatic system and release larval parasites (microfilariae or Mf) that circulate in the blood. More...

Some High-Cholesterol Genes Differ Between Countries

Genome-wide association studies (GWAS) have been very successful in identifying genetic variants linked to cardiovascular disease (CVD) and to cardiometabolic traits. Due to the improving predictive accuracy of these variants, genetic risk prediction could soon be implemented in clinical settings. More...
