Study shows how cancer protein changes may accelerate tumorigenesis and metastasis

Understanding the genetic mutations and protein changes that take place in the progression of cancer is key to its treatment. Mutations in the gene TP53 and concomitant mutant p53 proteins in cancer cells have become notorious over the course of multiple studies of several different types of cancers.

Scientists uncover important functions of a special protein during cell division

In a new study, researchers from the University of Copenhagen have discovered two important functions of a protein called RTEL1 during cell division.

Novel anti-cancer medicine could improve current therapy for ER+ breast cancer

The anti-cancer medicine venetoclax could improve the current therapy for estrogen receptor-positive breast cancer - the most common form of breast cancer in Australia - according to preclinical studies led by Walter and Eliza Hall Institute researchers.

Study: Recombination is crucial for proper segregation of chromosomes into germs cells

From avocado plants to baker's yeast, humans to zebras, sexually reproducing organisms must create germ cells that contain half the number of chromosomes found in a typical body cell.

Harmful effects of BPA can be reversed by administering coenzyme Q10

Exposure to bisphenol A (BPA), an industrial chemical used to make certain plastics and resins, inner coatings for food cans and bottle tops, thermal paper used in store receipts, dental sealants and so on, is a concern because of possible adverse health effects, including a reduction in fertility.

Cell division and its role in cancer development

To replace aging and worn cells, the body primarily uses a process called mitosis, in which one cell divides into two. When a cell is ready to divide, it duplicates its DNA so a complete copy is available for each of the daughter cells.

Study unravels mechanisms responsible for postnatal skin expansion

In adult tissue, the number of cells in each tissues and organs remains constant, and any new cells produced by cell division need to be compensated by the loss of other cells.

Lactating mothers' nicotine exposure may put babies at risk for skull defects

Lactating mothers who use e-cigarettes or nicotine replacement therapies may be putting their breastfed babies at risk for skull defects, a new study in animals suggests.

Bayreuth researchers discover natural protective mechanism against cancer

Susanne Hellmuth and Olaf Stemmann from the Chair of Genetics at the University of Bayreuth have discovered a natural protective mechanism that leads to the programmed death of potentially diseased cells.

Researchers discover physiological mechanisms underlying pediatric B-ALL

B-cell acute lymphoblastic leukemia (B-ALL) is characterized by the accumulation of abnormal immature B-cell precursors in the bone marrow and is the most common pediatric cancer.

Meis1 protein plays key role in stopping cell division in the heart

UT Southwestern Medical Center scientists have discovered a protein that works with others during development to put the brakes on cell division in the heart, they report today in Nature.

EMBL researchers create ‘virtual embryo’ for single-cell studies

Researchers from EMBL Heidelberg and from the University of Padua School of Medicine have created the first complete description of early embryo development, accounting for every single cell in the embryo.

New study raises red flags about strategy to block cancer drug resistance

Sooner or later, most cancer patients develop resistance to the very chemotherapy drugs designed to kill their cancer, forcing oncologists to seek alternatives.

Advance in understanding actin sheds light on cell function

Scientists have discovered more about actin, a chemical modification on one of the most abundant and important proteins.

A special diet can help in certain cases of asthma, study suggests

Can a special diet help in certain cases of asthma? A new study at the University of Bonn at least points to this conclusion. According to the study, mice that were switched to a so-called ketogenic diet showed significantly reduced inflammation of the respiratory tract.

Researchers uncover novel role for autophagy in the brain

Scientists from the laboratory of Dr. Natalia Kononenko at the CECAD Center of Excellence in Aging Research at the University of Cologne have found out that autophagy - the process of cellular self-recycling, or waste clearance - is dispensable for the survival of the neurons in mice.
