Acetaminophen_Toxicity_700x233

Signs of an overdose – microRNAs identify drug toxicity

When we think of drug overdoses, we typically think of controlled substances – e.g., illegal drugs or prescription drug abuse. It might come as a surprise, then, to hear that overdose of acetaminophen (APAP), the common over-the-counter analgesic used for headaches, fevers, and other minor ailments, is also a serious public health concern. Data from… Read article →



Exosomes_700x233

Maximizing quantity and purity of exosomal RNA for liquid biopsy

Exosomes are small membrane-bound vesicles ranging in size from 30 to 100 nm. They have been successfully isolated from multiple biofluids, including blood, plasma, urine and cerebrospinal fluid, and are being increasingly investigated for use in liquid biopsy. Although their primary function was once thought to be waste removal, further study has determined that exosomes… Read article →

Big things in small packages for liquid biopsy: extracellular communication via exosomes

Cells utilize multiple mechanisms to send messages. Long-range signaling, the production of molecules from a single organ which then travel through the bloodstream to the rest of the body, is regulated by the endocrine system. Signaling molecules secreted by the endocrine system include steroid hormones, growth factors, glycoproteins and catecholamines. The list of endocrine organs… Read article →
