Apoptosis is programmed cell death, the body's normal method of disposing of damaged, unwanted, or unneeded cells.

Researchers identify new mechanism that protects against Salmonella infection

Mice study has revealed a formerly unknown interaction between an immune cell protein and molecules extracted from dietary fiber.

Novel molecular survival strategy of Shigella bacterium uncovered

Enteric pathogens, such as the bacterium Shigella, can cause severe intestinal disease with bloody diarrhea. In a new study, researchers from Tokyo Medical and Dental University (TMDU) discovered a novel molecular survival strategy by which Shigella is able to cause damage to the intestines despite two elaborate protective mechanisms used by host cells.

Study shows DNA damage causes cells to reprogram themselves into stem cells

Researchers have discovered that when DNA in the moss Physcomitrella patens is damaged, it causes cells to reprogram on their own to change into stem cells.

Researchers identify mechanism that prevents death of neurons

When our neurons -- the principle cells of the brain -- die, so do we. Most neurons are created during embryonic development and have no "backup" after birth.

Study shows efficacy of L-Grb2 in preclinical models of ovarian and uterine cancer

The cover for issue 29 of Oncotarget features Figure 5, "In vivo effects of treatment with L-Grb2 in combination with anti-angiogenic therapy in an ovarian tumor model," by Lara, et al. which reported that adaptor proteins such as growth factor receptor-bound protein-2 play important roles in cancer cell signaling.

Scientists gain insights into how parasitic bacterium gives rise to lesions

Bacteria of the genus Bartonella are parasites that can be transmitted to humans via insect bites and animal scratches, resulting in an infection known as "bartonellosis." Cat-scratch disease and trench fever are forms of bartonellosis caused by different Bartonella species infecting humans.

Study reveals the negative effects of silicone breast implants

Silicone molecules extracted from breast implants can trigger the processes in human cells that result in apoptosis.

Protein dynamics can help fight bacterial infections

When pathogenic bacteria infect, the body’s immune system attempts to remove these invaders. One method to do this is to trigger an inflammatory response.

Researchers discover how a microRNA protects vascular integrity

Ludwig-Maximilian-Universitaet in Munich researchers have discovered a hitherto unknown molecular function of a specific microRNA that preserves integrity of the endothelium and reduces the risk of atherosclerosis.

Cryo-electron microscopy helps visualize PANX1 protein at near-atomic level

For the first time, researchers from Van Andel Institute have explained the near-atomic level structure of a molecular route that has crucial roles to play in the regulation of blood pressure, cell death, inflammation, and human development.

Study demonstrates the role of p53 gene in cell cycle regulation and apoptosis

The p53 gene is crucial in cell biology and thus cell replacement therapy. The function of this gene is to control the cell cycle and stop tumor formation.

New Players In The Programmed Cell Death Mechanism

Apoptosis is a form of 'cell suicide', in which a series of programmed molecular steps in a cell lead to its death.

Scientists discover molecular mechanism that regulates the body's immune sentinels

A team at the Centro Nacional de Investigaciones Cardiovasculares, working in partnership with researchers at Mount Sinai Hospital in New York, has discovered a new molecular mechanism mediated by nuclear receptors that determines the identity and expansion of macrophages--one of the cell types that act as immune sentinels in the body.
