Possible Tool To Study Aging From “Selfish” DNA In Animal Mitochondria
2012-08-10 09:14:10

Researchers at Oregon State University have discovered, for the first time in any animal species, a type of “selfish” mitochondrial DNA that is actually hurting the organism and lessening its chance to survive — and bears a strong similarity to some damage done to human cells as they age. The findings, just published in the journal PLoS One, are a biological oddity previously unknown in animals. But they may also provide an important new tool to study human aging,...

Inflammation and cell stress play important roles in the death of insulin-secreting cells and are major factors in diabetes. Cell stress also plays a role in Wolfram syndrome, a rare, genetic disorder that afflicts children with many symptoms, including juvenile-onset diabetes. Now a molecule has been identified that's key to the cell stress-modulated inflammation that causes insulin cells to die, report scientists at Washington University School of Medicine in St. Louis, the University of...

3D movie at ℠ultraresolution´ shows how cell´s machinery bends membrane inwards Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have combined the power of two kinds of microscope to produce a 3-dimensional movie of how cells ℠swallow´ nutrients and other molecules by engulfing them. The study, published today in Cell, is the first to follow changes in the shape of the cell´s membrane and track proteins thought to...

The popular belief that "cancer originates due to DNA mutations” is wrong” according to Samil Ozavar, who is the President of GEMM Research Ltd. Malignant transformation actually takes place due to an excessive build up of ATP in the cell that force a premature and uncontrolled cell division. A structural damage to the mitochondrial membrane channels that regulate the ATP flow to the cytosol are responsible for the excessive energy build that may lead to the formation of a...

Programmed Cell Death Explained By Lace Plants
2012-07-25 08:21:31

Programmed cell death (PCD) is a highly regulated process that occurs in all animals and plants as part of normal development and in response to the environment. New research published in BioMed Central's open access journal BMC Plant Biology is the first to document the physiological events in the lace plant (Aponogeton madagascariensis) which occur via PCD to produce the characteristic holes in its leaves. The aquatic lace plant, endemic to Madagascar, uses PCD to generate holes in its...

Cell is a peer-reviewed scientific journal founded by Benjamin Lewin in January 1974 with the sponsorship of MIT Press. Lewin bought the rights to the journal in 1986 and published it under his own publishing arm Cell Press. Cell Press was sold to Elsevier in 1999, which currently publishes Cell twice monthly. Cell Press publishes several biomedical journals, including Cell, Neuron, Immunity, Molecular Cell, Developmental Cell, Cancer Cell, Current Biology, Structure, Chemistry &...
