Researchers discover new signaling events that trigger metastasis in ovarian cancer cells

Like pancreatic cancer, cancer of the ovaries is notorious for being discovered at a relatively late stage - after it has spread to other sites in the body. It is not called "the silent killer" for nothing.

Mitochondrial stress can trigger tumor-related metabolic shifts, study finds

Cancerous tumors must be fed. Their unregulated growth requires a steady stream of blood flow and nutrients. Thus, one way that researchers have tried to wipe out cancer is to target cells undergoing the metabolic shifts that enable a tumor's rapid growth.

New bioinformatics tool can analyse 40,000 proteins per minute

Biology and computing have joined forces to create a piece of software that analyses mutations in proteins; these mutations are potential inducers of diseases, such as cancer.

Researchers uncover mechanism of two-in-one sensor protein KdpD

Uptake of potassium by bacteria is regulated by a single protein that senses the concentration of this cation both inside the cell and in the external medium, and controls the expression of the corresponding transport protein accordingly.

Motor protein Myo1c uses actin cytoskeleton as 'track' for Neph1 transport

The motor protein Myo1c binds to Neph1, a protein crucial for ensuring effective filtration by the kidney, and serves as one mode of its cellular transport, according to findings by investigators at the Medical University of South Carolina and their collaborators reported in the May 16, 2016 issue of Molecular and Cellular Biology.

Unlocking the dark proteome: an interview with Dr Kriwacki

The term dark proteome refers to proteins whose structural features and thus functions are not well understood. Many proteins within the dark proteome do not fold into stable three-dimensional structures. These proteins are called intrinsically disordered proteins (IDPs) and feature highly flexible, disordered confirmations.

lncRNA in placenta may help protect unborn baby from invading pathogens

The human placenta is an organ unlike any other. During the course of nine months it is formed by the embryo, sustains life and then is shed.

Study shows over-expression of adhesion molecules in fat tissues protects mice from obesity, diabetes

Okayama University researchers report that the overexpression of an adhesion molecule found on the surface of fat cells appears to protect mice from developing obesity and diabetes. The findings, published in the journal Diabetes, March 2016, may fuel the development of new therapies targeting these diseases.

Scientists develop new technology that helps visualize translation of mRNA into proteins

For the first time, scientists at Albert Einstein College of Medicine have developed a technology allowing them to "see" single molecules of messenger RNA as they are translated into proteins in living mammalian cells. Initial findings using this technology that may shed light on neurological diseases as well as cancer were published online today in Science.

UNC scientists develop new optogenetic tool to study function of different proteins

Scientists at the University of North Carolina School of Medicine have developed a way to embed light-responsive switches into proteins so that researchers can use lasers to manipulate protein movement and activity within living cells and animals.

UT Southwestern scientists discover mutation that causes X-linked reticulate pigmentary disorder

UT Southwestern Medical Center researchers have discovered a mutation that causes a rare systemic disorder known as X-linked reticulate pigmentary disorder (XLPDR) and, significantly, the unexpected cellular mechanism by which the mutation causes the disease.

High-throughput RNA interference screen identifies potential drug target against henipaviruses

The closely related Hendra and Nipah viruses (referred to jointly as henipaviruses) are deadly cousins of the more common mumps, measles, and respiratory syncytial viruses, all members of the paramyxovirus family. Henipavirus outbreaks are on the rise, but little is known about them, partly because research has to be conducted under extreme level containment conditions.

Cell biologists identify new way for curing cancer and vessel diseases

Cell biologists from the Lomonosov Moscow State University discovered a new way of regulating of cell motility -- this discovery will make possible development of new drugs for curing onco- and vessel diseases.

UT Southwestern researchers identify new role for protein linked to neurological disorders and cancers

Researchers at UT Southwestern Medical Center have identified a second role for a class of RNA-binding proteins, revealing new insights about neurological diseases and conditions associated with this protein such as autism, epilepsy, and certain types of cancer.

WSU researcher explores new drugs to treat neurological disorders linked to autophagic dysfunction

Repairing the brain's "house-cleaning function," which could help people with Alzheimer's, Parkinson's, amyotrophic lateral sclerosis (ALS) and 100 other diseases, is the focus of recently funded research at Washington State University.

Study identifies new mechanism for controlling HIV replication

Researchers at University of California, San Diego School of Medicine have discovered that HIV infection of human immune cells triggers a massive increase in methylation, a chemical modification, to both human and viral RNA, aiding replication of the virus.

Scientists discover role of nucleocytoplasmic transport in specific forms of ALS and FTD

Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are two devastating adult-onset neurodegenerative disorders.

Researchers find how microtubules, motor proteins assemble into macroscopic networks

What bones are to bodies, the cytoskeleton is to cells. The cytoskeleton maintains cellular structure, builds appendages like flagella and, together with motor proteins, powers cellular movement, transport, and division. Microtubules are a critical component of the cytoskeleton, vital for cell division and, because of that, an excellent target for chemotherapy drugs.

New discovery may help researchers tackle mitochondrial diseases and age-related diseases

Buck Institute faculty Judith Campisi, PhD, says age researchers need to stop thinking of cellular senescence, now accepted as an important driver of aging, as a single phenotype that stems from genotoxic stress. Research from her lab reveals that cellular senescence, a process whereby cells permanently lose the ability to divide, is also induced by signaling from dysfunctional mitochondria - and that the arrested cells secrete a distinctly different "stew" of biologically active factors in a process unrelated to the damaging free radicals that are created in mitochondria as part of oxygen metabolism.

UCLA discovery could lead to new therapies for autism

UCLA scientists have discovered that an overlooked region in brain cells houses a motherlode of mutated genes previously tied to autism. Recently published in Neuron, the finding could provide fresh drug targets and lead to new therapies for the disorder, which affects one in 68 children in the United States.
