Scientists reveal how a common gene mutation in ALS and FTD disrupts normal cell function

Researchers have determined how the most common gene mutation in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) disrupts normal cell function, providing insight likely to advance efforts to develop targeted therapies for these brain diseases.

Determining the dynein-dynactin complex structure: an interview with Dr Gabriel C. Lander

This is a macromolecular assembly is made up of two components, dynein and dynactin, that works to move molecular cargo (organelles, RNA, vesicles, proteins, viruses) along microtubule highways within our cells.

Sigma 1 receptor appears to play vital role in supporting the retina

A receptor that is already a target for treating neurodegenerative disease also appears to play a key role in supporting the retina, scientists report.

Scientists develop biosensor to measure abnormal activity of cell 'fuel' carrier

To be able to function, cell mitochondria import "fuel" using a carrier, the Mitochondrial Pyruvate Carrier (MPC). In order to determine whether the MPC is still functional in malignant cells, the team of Professor Jean-Claude Martinou, at the University of Geneva, Switzerland, has just developed a biosensor to measure its live activity.

Researchers uncover new mechanism that p53 protein uses to trigger cell death

Researchers have identified a new mechanism that the tumor suppressor protein p53 uses to trigger cell death via apoptosis and have shown how the process could be harnessed to kill cancer cells. St. Jude Children's Research Hospital scientists led the study, which appears today in the scientific journal Molecular Cell.

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.

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.

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.

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.

New study sheds light on mechanism that affects AID enzyme

A new study by immunology researchers at the IRCM led by Javier M. Di Noia, PhD, sheds light on a mechanism affecting AID, a crucial enzyme for the immune response. The scientific breakthrough, published in the latest issue of The Journal of Experimental Medicine, could eventually improve the way we treat the common flu, as well as lymphoma and leukemia.

RNA could be a potential target for new anticancer drugs, say UC Berkeley scientists

Most of today's anticancer drugs target the DNA or proteins in tumor cells, but a new discovery by University of California, Berkeley, scientists unveils a whole new set of potential targets: the RNA intermediaries between DNA and proteins.

Common cancers deform mitochondria to create conducive environment for tumor growth

In a breakthrough in the understanding of how cancer does its deadly work, researchers at the University of Virginia School of Medicine have shown that many cancers - including nearly all pancreatic cancers - enslave and deform mitochondria, the powerhouses of cells, to create an environment more conducive to tumor growth.
