New enzyme may help curb chronic kidney disease

University of South Australia researchers have identified an enzyme that may help to curb chronic kidney disease, which affects approximately 700 million people worldwide.

Host cell transmembrane protein MARCH8 targets lysine residues to inhibit SARS-CoV-2 and other viruses

A new study deals with the inhibitory activity of a membrane protein that has broad-spectrum activity against multiple viruses, showing that this is due to its effect on cytoplasmic lysine residue incorporation into replicating virions.

A missing protein explains the appearance of tumor cells in people with Mulibrey syndrome

Researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine (CABIMER), in collaboration with the Swiss Institute for Experimental Cancer Research (ISREC) have studied the mechanisms behind the higher tendency of people with Mulibrey syndrome to develop tumors.

New approach harnesses disease-causing proteins to combat cancer

Over many decades now, traditional drug discovery methods have steadily improved at keeping diseases at bay and cancer in remission. And for the most part, it's worked well.

Discovery of protein function could be important for future chemotherapy treatment

Chemotherapy attacks all cells in our body and not just cancer cells, which is why patients undergoing the treatment often experience side effects such as physical weakness, hair loss and nausea.

Researchers discover a mechanism that cells use to degrade microRNAs

UT Southwestern researchers have discovered a mechanism that cells use to degrade microRNAs (miRNAs), genetic molecules that regulate the amounts of proteins in cells.

Study implicates new gene as driver of motor neuron diseases

Failures in a quality control system that protects protein-building fidelity in cells can lead to motor neuron degeneration and related diseases, according to a new study from an international team co-directed by Scripps Research molecular biologist Claudio Joazeiro, PhD.

Improved type of PROTAC enhances intracellular accumulation and protein knockdown

Cancer therapies sometimes involve drugs that mediate the breakdown of specific intracellular proteins that participate in cancer formation and proliferation.

New study expands the knowledge on tumor-suppressor role of HERC proteins

The RAF protein could be a therapeutical target to treat the tumor growth in regulated pathways by the p38 protein, according to a new study published in the journal Scientific Reports by a team of experts of the Faculty of Medicine and Health Sciences of the University of Barcelona and the Bellvitge Institute for Biomedical Research.

Siah2 Gene Control could Help Treat Melanomas More Effectively

To develop improved cancer immunotherapies, it is essential to understand how cancers shut down the natural immune response to foreign antigens. This current study demonstrates how mice lacking the Siah2 gene, fail to develop BRAF-mutation carrying melanoma from the corresponding cells, completely rejecting them. This could help in boosting the anticancer effect of existing specific immune checkpoint inhibitors, such as anti-PD-1 drugs.

Discovery may provide clues for treatment of autism and schizophrenia

Researchers at the Case Western Reserve University School of Medicine have identified that a gene critical to clearing up unnecessary proteins plays a role in brain development and contributes to the development of autism spectrum disorders and schizophrenia.

Study: MIB2 improves inflammation by degrading CYLD enzyme

The tumor suppressor CYLD lysine 63 deubiquitinase (CYLD) is a deubiquitinating enzyme that suppresses polyubiquitin-dependent signaling pathways, including the proinflammatory and cell growth-promoting NF-κB pathway.

Researchers find a weak spot in cancer cells

Cancer cells form tumors. This statement, simple as it seems, hides a complex failure of normal immune responses that should eliminate tumor cells from the body before they ever form viable cancer masses.

Study uncovers how simpler organisms manage recycling of incomplete proteins

Our cells' process for transforming genes into useful proteins works much like an automobile factory's assembly line; there are schematics, parts, workers, motors, quality control systems and even recycling crews.

Mechanism behind how diabetes causes muscle loss revealed

Diabetes mellitus is associated with various health problems including decline in skeletal muscle mass. A research group led by Professor Wataru Ogawa at the Kobe University Graduate School of Medicine revealed that elevation of blood sugar levels leads to muscle atrophy and that two proteins, WWP1 and KLF15, play key roles in this phenomenon.

Researchers identify LZTR1 as evolutionarily conserved component of RAS pathway

Mutations in RAS proteins initiate many of the most aggressive tumors, and the search for pharmacological inhibitors of these proteins has become a priority in the battle against cancer. Michail Steklov, Francesca Baietti, and colleagues from the Anna Sablina lab identified LZTR1 as an evolutionarily conserved component of the RAS pathway.

Inhibition of one protein clears toxic clumps seen in Parkinson's disease, study finds

A defining feature of Parkinson's disease is the clumps of alpha-synuclein protein that accumulate in the brain's motor control area, destroying dopamine-producing neurons.

Scientists discover new details about UHRF1 protein

Epigenetic changes often play an important role in cancer, because they cause the genetic material to be read incorrectly at certain locations. Genes that are especially critical are those that control the growth and death of cells.

Scientists take important step to understand mechanisms that cause Huntington's disease

The neuroscientist Dr David Vilchez and his team at CECAD, the University of Cologne's Cluster of Excellence for Aging Research, have made an important step towards understanding the mechanisms that cause the neurodegenerative disorder Huntington's disease.
