Profiling microRNA from exosomes and blood

Exosomes are nano-sized vesicles, secreted by all types of cells and found abundantly in biofluids like blood, saliva and urine. These extracellular vesicles carry multiple functional passengers including DNA, miRNA, non-coding RNA and proteins, and function as intercellular communication vehicles by transporting molecules between specific cells. microRNAs are small non-coding RNAs that play an intricate… Read article →

Getting insight into the body: it’s all about the blood

Blood tells us lots of things. From cardiovascular health to cholesterol to inflammation to vitamin D levels – there is no shortage of information. Historically, blood was used to determine physiological and biochemical states, such as disease and organ function – but now, there are new technologies being developed to run the next generation of… Read article →

If you can’t grow it, you can’t study it. How can we sequence unculturable bacteria?

Sequencing bacteria helps us detect mutations that might be important for antibiotic resistance, virulence changes and other variations within a species. A major complication, though, is the fact that not every bacterium can be successfully grown in culture. So how can you sequence something when you can’t culture it? A recent study points to the… Read article →
