Heme, a Poisonous Nutrient, Tracked by ‘Green Lantern’ Sensor

greenandred.PNG

The toxin heme is essential to life, but cells must make use of it sparingly and carefully, as poor heme management can lead to Alzheimer's, heart disease and cancer. Researchers at the Georgia Tech have tailored ratiometric sensors to tracks heme's movements in yeast cells for the first known time.

Research Explains the Role of the Gene BRCA1 in DNA Repair

Scientists at the University of Birmingham are a step closer to understanding the role of the gene BRCA1. Changes in this gene are associated with a high risk of developing breast and ovarian cancer.

By increasing the level of a specific microRNA (miRNA) molecule, researchers have for the first time restored chemotherapy sensitivity in vitro to a line of human pancreatic cancer cells that had developed resistance to a common treatment drug.

Why Fruit Fly Sperm Are Giant

116306_web.jpg

In the animal kingdom, sperm usually are considerably smaller than eggs, which means that males can produce far more of them. Large numbers of tiny sperm can increase the probability of successful fertilization, especially when females mate with several males.

Among the valuable holdings in London's Wellcome Library is a rough pencil sketch made in 1953 by Francis Crick. The drawing is one of the first to show the double-helix structure of DNA--Nature's blueprint for the design of sea snails, human beings, and every other living form on earth.

Metagenomics Pathogen Detection Tool Could Change How Infectious Diseases Are Diagnosed

Dr.Schlaberg.jpg

Scientists at the University of Utah, ARUP Laboratories, and IDbyDNA, Inc., have developed ultra-fast, meta-genomics analysis software called Taxonomer that dramatically improves the accuracy and speed of pathogen detection. In a paper published today in Genome Biology, the collaborators demonstrated the ability of Taxonomer to analyze the sequences of all nucleic acids in a clinical specimen (DNA and RNA) and to detect pathogens, as well as profile the patient’s gene expression, in a matter of minutes.

Scientists Capture the Elusive Structure of Essential Digestive Enzyme

116348_web.jpg

Using a powerful combination of techniques from biophysics to mathematics, researchers have revealed new insights into the mechanism of a liver enzyme that is critical for human health. The enzyme, phenylalanine hydroxylase, turns the essential amino acid phenylalanine -- found in eggs, beef and many other foods and as an additive in diet soda -- into tyrosine, a precursor for multiple important neurotransmitters.

Nebraska Medicine, UNMC Offer New Service for Sickle Cell Disease Patients

Red blood cell exchange offers the risk lowering benefit of frequent blood transfusions but does so without increasing the iron stored in the body. Patients are connected to an apheresis machine which removes sickled red cells and replaces them with normal red cells from donors.

Alabama Woman Completes Year in Verapamil-Diabetes Clinical Trial, More Participants Needed

UAB physician Fernando Ovalle says one of the more difficult aspects of finding enrollees for the trial is that many physicians immediately think adults who show diabetic symptoms are likely type 2 diabetics when — if their body mass index is below 30 — it may actually be type 1 diabetes.

In addition the technique to grow the blood vessels in a 3D scaffold cuts down on the risk of transplant rejection because it uses cells from the patient. It was developed by researchers from the University of Bath's Department of Pharmacy and Pharmacology, working with colleagues at Bristol Heart Institute.

Neutrons Probe Structure of Enzyme Critical to Development of Next-Generation HIV Drugs

16-G00322_Feature_Kovalevsky_ornlStory.jpg

A team led by the Department of Energy’s Oak Ridge National Laboratory used neutron analysis to better understand a protein implicated in the replication of HIV, the retrovirus that causes AIDS. The enzyme, known as HIV-1 protease, is a key drug target for HIV and AIDS therapies. The multi-institutional team used neutron crystallography to uncover detailed interactions of hydrogen bonds at the enzyme’s active site, revealing a pH-induced proton ‘hopping’ mechanism that guides its activity.
