Bisphenol A (BPA), used, for example, in the production of food packaging, may negatively affect fertility, according to animal studies. The mechanisms responsible for its effect on female reproductive cells are currently being investigated by Dr. Anna Ajduk from the University of Warsaw.

Lymphocytes are white blood cells that regulate the immune system. If they have some 'experience' with an allergenic protein and get transplanted into another organism, that transfer will strengthen the immune reaction and the body will start to defend itself better against this protein. The experiment was conducted by scientists from the Institute of Animal Reproduction and Food Research of the Polish Academy of Sciences in Olsztyn.

A new gene called ATRIP, whose mutations cause a high risk of breast cancer, has been discovered by Polish researchers in cooperation with scientists from Canada, reports Dr. Cezary Cybulski, a geneticist from the Department of Genetics and Pathomorphology of the Pomeranian Medical University in Szczecin.

Researchers have shown that the higher the level of Prolactin-Induced Protein (PIP) in breast cancer cells, the better the effects of chemotherapy. The discovery may be of key importance in the choice of therapy for patients suffering from breast cancer.

Professor Ewa Szczurek's team from the University of Warsaw employed artificial intelligence to develop new peptides with promising antibacterial activity. In their work, the researchers used their own, innovative AI solutions.

Scientists from the Jagiellonian University described in Nature Communications a key discovery concerning an extremely important modification of proteins produced in cells. The mechanism called hypusination is important in the development of cancer, neurodegenerative diseases and diabetes.

Eating habits, the use of stimulants, and even playing sports can leave traces in specific places in the DNA. Biologists from the University of Lodz together with other Polish scientists are conducting research, the results of which can be used in forensic science.

Higher daily physical activity is associated with lower susceptibility to upper respiratory tract infections (colds), shows a study involving 104 Polish preschoolers.

Polish scientists are among the first in the world to have shown that stem cells can be successfully used in the treatment of diabetic foot ulcer. In their opinion, this is an important step towards the development of cell therapies.
