Liquid Biopsy Tests Identified Cell-Free Tumor DNA Mutations

The feasibility of using cell-free circulating tumor DNA (ctDNA) next-generation sequencing (NGS) from liquid biopsies as a complement or alternative to tissue NGS has been evaluated. More...

Simple Blood Test Vastly Improves Severe Liver Disease Detection

A new non-invasive method of predicting the risk of developing a severe form of liver disease could ensure patients receive early and potentially life-saving medical intervention before irreversible damage is done. More...

Unnecessary Endoscopies Could Be Avoided with Fecal Blood Test

The majority of primary care patients referred for bowel endoscopy do not have significant colorectal disease (SCD), and are unnecessarily exposed to a small but realistic risk of severe endoscopy-associated complications. More...

Image: An experiment examining retina tissue for mHtt deposition in GFAP-ir astrocytes in R6/2 mouse model of Huntington’s Disease. Green: glial fibrillary acidic protein (GFAP); Red: mutant huntingtin protein (mHtt). (A) A low magnification picture illustrates GFAP-ir astrocytes and mHtt deposits from the retinal wholemount of 12-week-old R6/2 (Huntington’s disease model) mouse. Scale bar = 50 µm. (B) A detailed confocal analysis of GFAP positivity, mHtt immunoreactivity, and DAPI counterstain (blue) revealed no colocalization of GFAP and mHtt. Scale bar = 20 µm (Image courtesy of PLoS One).

Changes in Eye Tissue May Enable Early Detection of Brain Diseases

Research with mouse models has shown that at least some diseases of the central nervous system (CNS) manifest as pathological changes in the retina of the eye and that these changes may be detected earlier than brain changes. The findings suggest that eye examination could be used for minimally invasive screening for these diseases. More...

Automated Test Strongly Predicts Ovarian Cancer Survival

The tumor microenvironment is pivotal in influencing cancer progression and metastasis and different cells co-exist with high spatial diversity within a patient, yet their combinatorial effects are poorly understood. More...

Genomic Fingerprinting Helps Predict Prostate Tumor Aggressiveness

Next-generation sequencing is revealing genomic heterogeneity in localized prostate cancer (CaP), but incomplete sampling of CaP multiclonality has limited the implications for molecular subtyping, stratification, and systemic treatment. More...

Genetic Cause Deciphered for Inherited Nerve Damage Afflicting Older Adults

An international team of researchers has identified a gene, MME, with a causative link to late-onset autosomal dominant axonal polyneuropathies. Patients initially develop loss of sensation and pain, then the illness can advance rapidly and lead to paralysis, inability to walk, and wheelchair dependency. More...
