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.

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.

Researchers investigate the role of auxin in regulating pathogen gene expression

Scientists have long known that the plant hormone auxin controls many aspects of plant growth, development, and responses to the environment. Only more recently have they begun to understand that there is also a link between auxin and leaf spotting diseases.

Cancer mutations occur in distinct patterns based on 3D structure of the genome

A new study from researchers at The University of Texas MD Anderson Cancer Center has discovered that mutations found in cancers do not accumulate randomly, but are found in distinct patterns that vary based on the three-dimensional organization of the genome in the cell as well as the underlying factors causing the mutations.

Research finds gene family critical to unlocking vertebrate evolution

New University of Colorado Boulder-led research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an important episode in evolution where new genes played a significant role in the evolution of novel traits in vertebrates.

Researchers unravel the molecular basis underlying colorectal cancer

A team of scientists has unraveled the molecular mechanism behind one of the causes of colorectal cancer, and a treatment target.

Researchers discover link between defensive responses in plants and crop parasite

Researchers at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan have discovered a link between defensive responses in plants and the beautiful but devastating crop parasite witchweed.

Study shows strigolactones enhance tolerance to insects in tobacco plants

A team of researchers at the Max Planck Institute for Chemical Ecology in Jena, Germany, has discovered that strigolactones, a class of novel plant hormones, mediate the fine-tuning of the production plant defensive substances in the stem of plants of the wild tobacco species Nicotiana attenuata.

Researchers identify a novel molecular mechanism of intestinal stem cells

Stem cells in the intestines maintain an excellent balance between two promising forms—developing into intestinal epithelial cells, or remaining as stem cells.

Biologists identify a molecular mechanism that underlies phenotypic plasticity

Evolutionary and developmental biologist Craig Albertson and colleagues at the University of Massachusetts Amherst report that they have identified a molecular mechanism that allows an organism to change the way it looks depending on the environment it is exposed to, a process known as phenotypic plasticity.

Researchers identify how airway cells work together in regeneration and aging

Researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have identified the process by which stem cells in the airways of the lungs switch between two distinct phases -- creating more of themselves and producing mature airway cells -- to regenerate lung tissue after an injury.

Researchers to develop new ways to prevent esophageal cancer

The incidence of esophageal adenocarcinoma has increased 8-fold over the past 50 years. This is one of the deadliest cancers, with a five-year survival rate of only 20 percent.

Bacteria-induced cell fusion provokes the immune system and causes host cell destruction

Burkholderia pseudomallei is a bacterium in the soil that causes melioidosis, a tropical disease with high morbidity and mortality.

Researchers identify osmotic stress as stimulator of cellular waste disposal

Cellular waste disposal, where autophagy and lysosomes interact, performs elementary functions, such as degrading damaged protein molecules, which impair cellular function, and reintroducing the resulting building blocks such as amino acids into the metabolic system.
