Single-Cell Analysis Sheds Light on Leukemia Cell Heterogeneity

Chromosomal instability plays a crucial role in the progression of cancer: it shapes the properties of tumor cells and drives the development of therapy resistance. Scientists from the German Cancer Research Center (DKFZ), the Heidelberg Stem Cell Institute HI-STEM and the European Molecular Biology Laboratory (EMBL) used state-of-the-art single-cell analysis methods to analyze the cellular heterogeneity of a specific form of acute myeloid leukemia.

Self-Eliminating e-Drive System Reverses Insecticide Resistance in Fruit Flies

Insecticides have been used for centuries to counteract widespread pest damage to valuable food crops. Eventually, over time, beetles, moths, flies and other insects develop genetic mutations that render the insecticide chemicals ineffective.

Hormonal Control of Caste Determination in Ants

Most ants have two morphologically differentiated adult castes - queens and workers - each irreversibly specialized for either reproduction or nonreproductive altruism such as foraging, defense and care of maternal brood. Adult gynes (virgin queens) normally have higher body mass, wings and frontal eyes, as well as enlarged ovaries and a sperm storage organ.

Mapping of Mouse Intestine Sheds Light on Immune Control and Adaptability

The intestine maintains a delicate balance in the body, absorbing nutrients and water while maintaining a healthy relationship with the gut microbiome, but this equilibrium is disrupted in parts of the intestine in conditions such as celiac disease, ulcerative colitis, and Crohn's disease.

Chromosome Abnormalities Found in Healthy Women’s Breast Cells

A new study from researchers at The University of Texas MD Anderson Cancer Center finds that, in healthy women, some breast cells that otherwise appear normal may contain chromosome abnormalities typically associated with invasive breast cancer. The findings question conventional thinking on the genetic origins of breast cancer, which could influence early cancer detection methods.
