Genetic Mutation Linked to Crohn's and Parkinson's Diseases

The inflammatory bowel diseases (IBD) are composed of two major subtypes, Crohn’s disease (CD) and ulcerative colitis (UC), which are distinguished by the distribution of chronic inflammatory changes. More...

Immune Response Tests Enable Rapid Antibiotic Decisions

A novel test uses quantitative multiplex gene expression to analyze a patient's immune system, or the host response, rather than looking for the presence of a pathogen that indicates whether there is an infection in the blood. More...

Lab-Developed Tests Compared with Approved Diagnostics

The debate about the role of the government-approved diagnostics in the regulation of laboratory-developed tests (LDTs) has focused attention on the analytical performance of all clinical laboratory testing. More...

New Gene Variant Linked to Prostate Cancer

Prostate cancer (PCa) is the most commonly diagnosed malignancy and the second leading cause of cancer-related death in men in the USA. The growth and survival of PCa cells are driven by androgens through activation of the androgen receptor (AR) and its target genes. More...

Liquid Biopsy Test Detects Eight Types of Cancer

Cancer researchers have developed a "liquid biopsy" blood test that can detect eight common cancer types through assessment of the levels of circulating proteins and mutations in cell-free DNA. More...

Cancerous Tissue Analysis Introduced Using On-chip Technology

A novel gene expression analysis technique has been introduced that can accurately measure levels of RNA quickly and directly from a cancerous tissue sample while preserving the spatial information across the tissue. More...

KRAS Mutations Revealed in Rare Brain Condition

Sporadic arteriovenous malformations of the brain, which are morphologically abnormal connections between arteries and veins in the brain vasculature, are a leading cause of hemorrhagic stroke in young adults and children. More...
