Scientists develop small molecule drug that prevents autophagy from starting in cancer cells

As a tumor grows, its cancerous cells ramp up an energy-harvesting process to support its hasty development. This process, called autophagy, is normally used by a cell to recycle damaged organelles and proteins, but is also co-opted by cancer cells to meet their increased energy and metabolic demands.

Early neuronal lysosomal dysfunction could help predict AD

Blood levels of altered lysosomal proteins may help detect preclinical Alzheimer’s disease, researchers report.

Specialized brain proteins may be detected in the blood samples of individuals with Alzheimer's disease

Specialized brain proteins that are involved in the removal of damaged nerve cell materials may be detected in the blood of people who were diagnosed with mild cognitive impairment or dementia due to Alzheimer's disease.

Duke researchers reveal how bladder cells can eject UTI-causing bacteria

Duke Medicine researchers have found that bladder cells have a highly effective way to combat E. coli bacteria that cause urinary tract infections (UTIs).

Scientists identify molecular 'lock' that enables Ebola virus to gain entry to cells

An international team including scientists from Albert Einstein College of Medicine of Yeshiva University and the U.S. Army Medical Research Institute of Infectious Diseases has identified the molecular "lock" that the deadly Ebola virus must pick to gain entry to cells.

Case Western Reserve researchers find potential game-changer for triple-negative breast cancer

Researchers at Case Western Reserve University combined finely crafted nanoparticles with one of nature's potent disrupters to prevent the spread of triple-negative breast cancer in mouse models.

Gene therapy is key to addressing Sanfilippo Syndrome, say Ohio scientists and clinicians

Gene therapy is the delivery of DNA into a patient's cells to replace faulty or missing genes—or adds new genes—in an attempt to cure cancer or make changes so the body is better able to fight off disease. Scientists and clinicians have identified a number of different ways to do this, in an effort to correct malfunctioning or mutated genes. Many gene therapy clinical trials are ongoing to assess the safety and potential benefits in patients with rare diseases.

Deben reports on the work of the Microscopy & Histology Core Facility at the University of Aberdeen

Deben reports on the work of the Microscopy & Histology Core Facility at the University of Aberdeen where a newly installed TEM and camera system have enhanced the services provided to users.

New fluorescent probes detect problems related to lysosomes

Lysosomes are the garbage disposals of animal cells. As the resources are limited in cells, organic materials are broken down and recycled a lot -- and that's what lysosomes do.

Synageva announces submission of Kanuma application to Cofepris for treatment of LAL Deficiency

Synageva BioPharma Corp., a biopharmaceutical company developing therapeutic products for rare disorders, announced today the submission to the Comisión Federal para la Protección contra Riesgos Sanitarios in Mexico for Kanuma as a treatment for patients with lysosomal acid lipase deficiency (LAL Deficiency), a rare genetic disease with significant morbidity and early mortality.

RAB3GAP complex plays important role in autophagy

Neurodegenerative disorders such as Alzheimer's disease are typically characterized by protein deposits in the brain. These are comprised of defective, insoluble proteins which no longer fulfill their function and which cells are unable to break down. The work group headed by Professor Christian Behl of the Institute of Pathobiochemistry of the University Medical Center of Johannes Gutenberg University Mainz has determined the RAB3GAP complex as a novel factor that influences the efficient degradation of proteins.

Scientists identify new cellular pathway affected in cystinosis

Scientists at The Scripps Research Institute have identified a new cellular pathway that is affected in cystinosis, a rare genetic disorder that can result in eye and kidney damage.

Study links lysosomal dysfunction with neonatal intestinal disorders

Neonatal intestinal disorders that prevent infants from getting the nutrients they need may be caused by defects in the lysosomal system that occur before weaning, according to a new Northwestern Medicine study.

Researchers explore how M6P deficiency affects different kinds of immune cells

A group of white blood cells known as B cells, which play a key role in the human immune response, need a protein-targeting signal called mannose 6-phosphate (M6P) in order to proliferate, differentiate, and present immune cell-activating antigens, according to a study in The Journal of Cell Biology.

Abnormal attachment of sugar to BACE1 enzyme leads to formation of Aβ plaques in the brain

Researchers at the RIKEN-Max Planck Joint Research Center in Japan have demonstrated that hallmark symptoms of Alzheimer's disease can be reduced when sugars are prevented from binding to one of the key enzymes implicated in the disease. The new findings, reported in EMBO Molecular Medicine, show that abnormal attachment of a particular sugar to the enzyme BACE1 is a critical factor leading to the formation of Aβ plaques in the brain, and that plaques were reduced and cognitive performance improved when this action was prevented in mice through loss of the enzyme GnT-III.

Chemical chaperone: A new therapeutic option for epilepsy

Researchers found out that the conformational defect in a specific protein causes Autosomal Dominant Lateral Temporal Lobe Epilepsy (ADLTE) which is a form of familial epilepsy. They showed that treatment with chemical corrector called "chemical chaperone" ameliorates increased seizure susceptibility in a mouse model of human epilepsy by correcting the conformational defect.

Artificial cells to devour undesirables: an interview with Dr. Takanari Inoue

If junk is not removed, pathological conditions can develop. For example, in one condition, the neutrophil count significantly decreases. Neutrophils remove pathogens and people with a reduced neutrophil count are more prone to infection, especially to rare bacteria that wouldn’t cause infection under normal conditions.
