Novel Active Substance Drives Cancer Cells Toward Self Destruction

A new active substance attacks a key protein in tumor cells, leading to complete degradation. In cell experiments, this caused cancer cells to lose their protection and die.

Discovery Reveals Greater Epigenetic Complexity in Unicellular Life

Multicellular organisms (animals, plants, human) all have the ability to methylate the cytosine © base in their DNA. This process, a type of epigenetic modification, plays an important role in conditions such as cancer and processes such as aging.

Sabotaging T Cell Exhaustion for Cancer Therapy

Like all hardworking things, the cytotoxic T lymphocytes (CTLs) of the immune system charged with detecting and destroying cancer cells tend to get very tired-so much so, in fact, that they can even die from exhaustion.

Neurons and Other Nondividing Cells Respond Differently to CRISPR-Cas9 Gene Editing

The gene editing tool known as CRISPR-Cas9 is changing what's possible for treating a wide range of diseases caused by genetic mutations.

Researchers Discover Molecular Switch That Helps Breast Cancer Cells Survive Stress

Cells are regularly faced with environmental stresses that may damage or destroy them. To survive, they quickly adjust their gene expression to protect themselves.

Researchers Reveal How the Brain Forms Hidden-State Inferences

Animals survive in changing and unpredictable environments by not merely responding to new circumstances, but also, like humans, by forming inferences about their surroundings-for instance, squirrels understand that certain bird noises don't signal the presence of a predator, so won't seek shelter when they later hear these same sounds.

Blocking a Hidden Tumor Pathway Revives the Immune System

A new study has discovered a molecular signal that tumors exploit to exhaust the T cells meant to destroy them-and how silencing that signal could revive the body's immunity.

Studying Disease Evolution Through Ancient DNA Analysis

Research institutions around the world house valuable genetic information that could help unlock countless medical mysteries. However, because DNA degrades over time, it is difficult for researchers to analyze DNA samples older than 20 years using conventional analytical approaches.

Plant Cell Duality: Balancing Adaptability in Skin Cells with Stability in Reproductive Cells

Mutations drive evolution, but they can also be risky. New research led by plant biologists at the University of California, Davis, published Nov. 10 in Proceedings of the National Academy of Sciences, reveals how plants control mutation rates in different stem cells to balance adaptability with safety and stability.
