Glaucoma and cell death: an interview with Dr. Vivek Gupta

Glaucoma is normally caused by increased pressure of aqueous humour fluid in the eye. A defining feature of this disease is destruction of a particular type of cells in the retina called retinal ganglion cells and excavation of the optic disc region.

DNA synthesis in the 3’ and 5’ direction possible using new template-directed method

When a cell divides, it passes on genetic information by producing copies of its DNA. Chemists have also learned to copy DNA. In the journal Angewandte Chemie, a German team has now introduced a new copying technique that uses a single strand of DNA as the “master copy”, like a cell, but does not require enzymes.

Herceptin® (trastuzumab) delivery methods: an interview with Dr Gustavo Ismael

Approximately 20% of all breast cancer patients have overexpression of HER2 (human epidermal growth factor receptor 2), resulting in a more aggressive phenotype, and a poor prognosis.

Friedreich Ataxia Research Alliance, USF ARC to host ‘Understanding a Cure’ symposium

Scientists, clinicians and patients will gather at the University of South Florida's Center for Advanced Medical Learning and Simulation (CAMLS) in downtown Tampa Sept. 6 to share research insights and energize the search for a cure for Friedreich's ataxia and related disorders.

Blood cells returned to stem cell state by Johns Hopkins researchers

Johns Hopkins scientists have developed a reliable method to turn the clock back on blood cells, restoring them to a primitive stem cell state from which they can then develop into any other type of cell in the body.

SSEA4+ marker helps identify and isolate precursors of insulin-producing pancreatic cells

For the millions of people worldwide with type 1 diabetes who cannot produce sufficient insulin, the potential to transplant insulin-producing cells could offer hope for a long-term cure. The discovery of a marker to help identify and isolate stem cells that can develop into insulin-producing cells in the pancreas would be a critical step forward and is described in an article in BioResearch Open Access, a new bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc.

Genetic key to severe malaria resistance uncovered

Researchers have identified two genetic variants linked with human resistance to severe malaria.

Rhomboid enzymes and malaria treatment: an interview with Sinisa Urban

Rhomboid enzymes live in the cell’s membrane where their job is to cut the anchors of proteins, which releases the target proteins from the membrane.

Cathepsins may attack one another instead of the bodily proteins

Researchers for the first time have shown that members of a family of enzymes known as cathepsins - which are implicated in many disease processes - may attack one another instead of the bodily proteins they normally degrade. Dubbed "cathepsin cannibalism," the phenomenon may help explain problems with drugs that have been developed to inhibit the effects of these powerful proteases.

Chronic nerve pain: researchers identify which sensory nerve cells are responsible

New research, led by academics at the University of Bristol and published in the journal Pain, has identified the subtypes of sensory nerve cells that are likely to contribute to long-term nerve pain from partial nerve injury. It is hoped this will aid in development of more effective pain killers.

Review explores whether HPV vaccination of young men is warranted and cost effective

Vaccination against human papilloma virus (HPV) is recommended for young women to protect them from HPV infection and cervical cancer. Male HPV immunization is increasingly a topic of debate in the medical community. A timely review of the literature published in Viral Immunology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers, explores whether HPV vaccination of young men is warranted and cost effective.

Mapping rhomboid enzymes could eventually lead to drugs to treat malaria

Johns Hopkins scientists have decoded for the first time the "stability blueprint" of an enzyme that resides in a cell's membrane, mapping which parts of the enzyme are important for its shape and function.

Parkinson’s disease treatment: an interview with Ted Dawson

Parkinson’s disease is a disorder which usually affects people in their 60’s and older. It is caused by the loss of dopamine neurons in the brain leading to rigidity, slowness of movement, tremor, problems with balance and so forth.

Antioxidants and pancreatic cancer risk: an interview with Dr Andrew Hart

The antioxidants that we mainly looked at were selenium, vitamin C and vitamin E. They are chemicals which inactivate pro-oxidants or free radicals. Smoking and normal metabolism can lead to the production of free radicals.

Vanderbilt researchers receives new $2.1M grant to develop microbrain bioreactor

Take a millionth of a human brain and squeeze it into a special chamber the size of a mustard seed. Link it to a second chamber filled with cerebral spinal fluid and thread both of them with artificial blood vessels in order to create a microenvironment that makes the neurons and other brain cells behave as if they were in a living brain. Then surround the chambers with a battery of sensors that monitor how the cells respond when exposed to minute quantities of dietary toxins, disease organisms or new drugs under development.

Protein associated with Huntington’s and other neurodegenerative diseases has several brain-specific forms

A protein essential for metabolism and recently associated with neurodegenerative diseases also occurs in several brain-specific forms. This discovery emerged in the course of a research project funded by the Austrian Science Fund FWF, the findings of which have now been published in the journal Human Molecular Genetics.

Egg allergy treatment for children: an interview with Dr Robert Wood

The tendency to get allergies is a fairly general one, which is mostly inherited – it tends to run in families. There are several foods that are most common for children to become allergic to: milk, egg and peanuts in most countries are the most common food allergies.

Keystone Symposia on Molecular and Cellular Biology receives Gates Foundation grant

Keystone Symposia on Molecular and Cellular Biology is pleased to announce that it has received a fourth grant from the Bill & Melinda Gates Foundation to promote discoveries that will solve urgent global health problems via support of infectious disease conferences in the "Keystone Symposia Global Health Series."

Heart-protective protein finally found

It is a cellular component so scarce, some scientists even doubted its existence, and many others gave up searching for its molecular structure. Now a team led by researchers at Johns Hopkins has defined the protein structural composition of mitoKATP, a potassium channel in the mitochondria of the heart and other organs that is known to protect against tissue damage due to a heart attack or stroke.

Promising path to Parkinson’s disease treatment

Using adult stem cells, Johns Hopkins researchers and a consortium of colleagues nationwide say they have generated the type of human neuron specifically damaged by Parkinson’s disease (PD) and used various drugs to stop the damage.
