Wistar Institute study shows that PI3K inhibitors may make a patient's cancer even worse

The enzyme phosphatidylinositol-3 kinase (PI3K) appears to be exploited in almost every type of human cancer, making it the focus of considerable interest as a therapeutic target, with many PI3K-inhibiting drugs currently in various stages of clinical development. However, PI3K inhibitors have only shown modest clinical activity with patients who receive these drugs experiencing very little improvement in survival.

NGS technology helps identify new mitochondrial disease gene

Next Generation Sequencing (NGS) technology offers an incredible opportunity for the rapid and relatively low-cost characterization of individual genomes, giving us a chance to make a substantial leap ahead in the molecular dissection of all mitochondrial disorders in humans.

New chemical compound reduces pancreatic cancer tumour growth by 80% in mice

Scientists from UCL (University College London) have designed a chemical compound that has reduced the growth of pancreatic cancer tumours by 80 percent in treated mice.

Cochlear Nucleus 6 Sound Processor approved by FDA for use with Nucleus 22 Cochlear Implant

Cochlear Limited, the global leader in implantable hearing solutions, announced today that the U.S. Food and Drug Administration (FDA) has approved the Cochlear™ Nucleus® 6 Sound Processor for use with the Nucleus 22 Cochlear Implant, giving those who have worn cochlear implants from the beginning (over 20 years in some cases) access to the latest breakthroughs in true wireless and automatic hearing. Released in 1985, the Nucleus 22 Implant was the first commercially available multi-channel cochlear implant in the world.

Nucleoporin proteins play significant role in maintaining embryonic stem cells

What if you found out that pieces of your front door were occasionally flying off the door frame to carry out chores around the house? That's the kind of surprise scientists at the Salk Institute experienced with their recent discovery that nucleoporins -- proteins that act as cellular 'doorways' to help manage what goes in and out of a cell's nucleus -- are actually much bigger players in expressing genes than previously thought.

TUSM researchers reveal how scratching evokes pleasurable sensation in chronic itch patients

It's long been known that scratching evokes a rewarding and pleasurable sensation in patients with chronic itch. Now, researchers in the Department of Dermatology and Temple Itch Center at Temple University School of Medicine may be closer to understanding why.

Promising results for multi-source DBS in Parkinson’s disease

Deep-brain stimulation targeting the subthalamic nucleus with a multiple-source constant-current device effectively suppresses motor symptoms in patients with advanced Parkinson’s disease, report researchers.

Brain protein key to binge drinking? An interview with Dr. Candice Contet

Alcohol binge drinking is mostly driven by positive reinforcement, a process in which a rewarding experience (e.g., the euphoria one feels when intoxicated) strengthens the behaviour leading to this experience (e.g., going to a bar).

Cell fusion triggers multiple genetic changes that convert normal cells to cancer cells

Although there is no one established universal cause of cancer, genetic changes are central to its development. The accumulation of spontaneous genetic changes, or mutations, that occur when cells divide can be hastened by exposure to carcinogens such as cigarette smoke (lung cancer) and infectious agents such as the papillomavirus (cervical cancer).

Scientists identify novel mechanism that can reorganize cell's genetic architecture to promote senescence

Senescence, a phenomenon in which cells cease to divide and grow, can be caused by everything from natural DNA damage to treatment with chemotherapy. However, several mechanisms allow for cells to bypass senescence and grow out of control, eventually becoming cancerous.

Researchers uncover critical role for two proteins in chromatin structure

A team of researchers at the IRCM led by François Robert, PhD, uncovered a critical role for two proteins in chromatin structure. Their breakthrough, recently published in the scientific journal Molecular Cell, helps explain how DNA is organized in our cells. This discovery could lead to a better understanding of what causes certain types of cancer, such as lymphoma.

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.

Study reveals molecular basis for endocrine therapy-resistant breast cancer

Mitsuyoshi Nakao, Director of the Institute of Molecular Embryology and Genetics in Kumamoto University and Associate Professor Noriko Saitoh revealed that a cluster of defined, non-coding RNAs are mechanistically involved in endocrine therapy resistance in human breast cancer cells. Furthermore, resveratrol, a kind of polyphenol, was found to repress these RNAs and inhibit the proliferative activity of breast cancer cells which had acquired resistance.

Researchers identify six mRNA isoforms that could be used to diagnose early-stage ovarian cancer

Ovarian cancer is notoriously difficult to diagnose and treat, making it an especially fatal disease. Researchers at University of California, San Diego School of Medicine and Moores Cancer Center have now identified six mRNA isoforms (bits of genetic material) produced by ovarian cancer cells but not normal cells, opening up the possibility that they could be used to diagnose early-stage ovarian cancer.

Discovery opens up new avenue for development of potential therapies to treat, prevent malaria

Scientists have identified a protein on the surface of human red blood cells that serves as an essential entry point for invasion by the malaria parasite. This discovery opens up a promising new avenue for the development of therapies to treat and prevent malaria.

Study offers new insights into construction of nuclear pores in nuclear envelope

In a recent study, a team of researchers led by Alwin Köhler at the Max F. Perutz Laboratories (MFPL) belonging to the University of Vienna and the Medical University of Vienna offer new insights into how nuclear pores are constructed in the nuclear envelope.

Researchers identify mechanism responsible for steroid resistance in leukemia patients

Researchers led by St. Jude Children's Research Hospital scientists have identified a mechanism that helps leukemia cells resist glucocorticoids, a finding that lays the foundation for more effective treatment of cancer and possibly a host of autoimmune diseases.

Findings provide glimmer of hope for treating diffuse intrinsic pontine gliomas

Using brain tumor samples collected from children in the United States and Europe, an international team of scientists found that the drug panobinostat and similar gene regulating drugs may be effective at treating diffuse intrinsic pontine gliomas (DIPG), an aggressive and lethal form of pediatric cancer.
