New nanoparticles can destroy drug-resistant cancer cells

Multidrug resistance, or MDR, is a process in which tumors become impervious to numerous drugs and is a major cause of failure in cancer chemotherapy.

New tool can provide non-invasive decision support for treating lung cancer

Personalized treatment options for patients with lung cancer have come a long way in the past two decades. For patients with non-small cell lung cancer, the most common subtype of lung cancer and the leading cause of cancer-related death worldwide, two major treatment strategies have emerged: tyrosine kinase inhibitors and immune checkpoint inhibitors.

Researchers develop a new method for siRNA stabilization

In the gene controlling mechanism, known as RNA interference, the expression of particular genes is downregulated by siRNAs or endogenic microRNAs.

New mechanism of metastatic cancer cells discovered in substrates of different stiffness

During metastasis, cancer cells actively interact with microenvironments of new tissues. How metastatic cancer cells respond to new environments in the secondary tissues is a crucial question in cancer research but still remains elusive.

New technology rapidly diagnoses sickle cell disease

Researchers at the University of Colorado Boulder and the University of Colorado Anschutz Medical Campus have developed a new way to diagnose diseases of the blood like sickle cell disease with sensitivity and precision and in only one minute.

Synthetic signals could help control tissue regeneration

For a tiny embryo to develop into an adult organism, its cells must develop in precise patterns and interact with their neighbors in carefully orchestrated ways.

Study shows cocaine use in mice leads to formation of synapses

Drugs of abuse, like cocaine, are so addictive due in part to their cellular interaction, creating strong cellular memories in the brain that promote compulsive behaviors.

Researchers discover how specific molecules promote cancer progression

The development of cancer is a highly complicated process, involving multiple genes and signaling pathways that become upregulated or downregulated throughout different stages of tumor growth and spread. Two of the most commonly altered genes in cancer are p53 and AKT.

Cell-cultured meat can surpass nutritional profile of conventionally farmed meat

Researchers have produced plant nutrients by genetically modifying the muscle cells of cows. These nutrients are not natively found in beef cells.

Researchers identify drug that could overcome tumor resistance

Scientists have discovered that a drug that may make some melanoma tumors perceptible to the immune system, enabling them to be better targeted.

Study provides new insights into molecular mechanisms of adipogenesis

The impairment of adipogenesis, the process in which fat cells (also known as adipocytes) accumulate to become fat tissue, can lead to many diseases such as diabetes, obesity, and heart conditions.

Lymphocytes play crucial role in controlling virus shedding in asymptomatic COVID-19 patients

COVID-19 remains stubbornly inconsistent. More than a million people have died and 35 million have been diagnosed, but a large fraction of people infected with the coronavirus--about 45%, according to recent estimates--show no symptoms at all.

Researchers demonstrate healing power of extracellular vesicles on a heart-on-a-chip

Extracellular vesicles (EVs) -- nanometer sized messengers that travel between cells to deliver cues and cargo -- are promising tools for the next generation of therapies for everything from autoimmune and neurodegenerative diseases to cancer and tissue injury.

Scientists find sensor protein which enables normal functioning of bladder

A team co-led by scientists at Scripps Research has found that the main sensor protein enabling our sense of touch also underlies the feeling of having a full bladder and makes normal bladder function possible.

Virus-mimicking drugs may overcome immunotherapy resistance in tumors

Researchers at the UCLA Jonsson Comprehensive Cancer Center have found that a drug that activates the body's natural defenses by behaving like a virus may also make certain stealthy melanoma tumors visible to the immune system, allowing them to be better targeted by immunotherapy.

Study offers renewed hope for children suffering from myofibrillar myopathies

Stephen Greenspan and Laura Zah were devastated when they learned their son Alexander had a rare genetic mutation, which causes a deadly neuromuscular disease with no known treatment or cure.

DNA structural changes play key role in the recovery phase after DNA damage

A research team from Cologne has discovered that a change in the DNA structure - more precisely in the chromatin - plays a decisive role in the recovery phase after DNA damage. The key is a double occupation by two methyl groups on the DNA packaging protein histone H3 (H3K4me2).
