Nanoparticles can Damage DNA, Increase Cancer Risk

...g DNA damage directly or if they are acting on the membrane and inducing a cascade of events resulting in DNA damage," Pacheco said. "Once we understand the mechanisms by which nanoparticles induce their toxicity, we will be better able to prevent or mitigate their harmful effects." In the meantime, the exp...

HIV/AIDS- Possible Cure From Within

...s that otherwise allows the virus to penetrate the membrane of cells it is about to infect, a process known as fusion.As no existing drugs affect this stage of infection, the team hopes the compound could be modified to form a new class of similar drugs. With nearly 40 million people living with HIV worldwi...

Key Found to Kill Cystic Fibrosis Superbug

...a4N), may lead to a susceptibility within the cell membrane to antibiotics. "We are very excited with these findings, as they will let us come up with novel molecules to disrupt the making of Ara4N," says Valvano. "These molecules could then be tested as novel antibiotics." Valvano is a Professor and Chair...

A New Target for Cancer Therapy-Integrin Alpha7 Molecule

... Integrin alpha7 belongs to a major class of cell membrane proteins that play a role in the attachment of a cell to the extracellular matrix (ECM), which is the material that holds cells within a particular type of tissue together. Integrins also help cells attach to one another and are involved in transmitt...

Scientists Discover How HIV Escapes Cells

...l. However, when they were replaced with synthetic membrane anchors and clumping domains, Gag regained its ability to get out of cells in exosomes. Gould believes that cells might have initially developed exosomes as a quality control mechanism to get rid of clumped proteins, which are generally broken and...

Researchers Discover Starch Cocktail Fuel for green Car

...en". The CO2 is separated from the hydrogen by a membrane and returned to the atmosphere. As the starch is from biomass - wood and plants - the same amount of CO2 is released by the conversion which is taken out of the atmosphere by plants to produce the starch in the first place. As such, the process is ca...

Super-oxidised Water Found Effective Against MRSA

... water, which is made by passing it through a salt membrane that generates the oxychlorine ions, kills bacteria, virus and fungi. The company claims that the solution is effective against Methicillin-resistant Staphylococcus aureus (MRSA). We would welcome any safe effective treatment which could help peo...

Role of Protein in the Development of Prostate Cancer Identified

...epithelial luminal cells express functional plasma membrane TRPM8 (PM-TRPM8) and that prostate cancer cells possessed higher PM-TRPM8 levels than normal cells. However, endoplasmic reticulum TRPM8 (ER-TRPM8) retained its function as a calcium release channel, independent of the differentiation state of the...

Study Revises Dynamin's Role in Nerve Cell Function

...ysically squeezes off a piece of the old vesicular membrane creating a brand new vesicle poised to take on a new load of neurotransmitter.' Based on this work in fruit flies, neuroscientists had assumed that dynamin 1 was necessary for the growth and function of all synaptic transmission. But Dr. Ryan, a...
