Future wood production quality tied to cambial function and regulation As large organisms, trees face some remarkable challenges, particularly regarding long-distance transport and communication. In addition to moving water and nutrients from their roots to their leaves, they must also integrate cell-to-cell communication over large areas. Furthermore, in order to function as a single, cohesive organism they must be able to effectively and efficiently send vital substances–such as...

Whitehead Institute scientists report that certain molecules present in high concentrations on the surfaces of many cancer cells could be exploited to funnel lethal toxic molecules into the malignant cells. In such an approach, the overexpression of specific transporters could be exploited to deliver toxic substances into cancer cells. Although this finding emerges from the study of a single toxic molecule and the protein that it transports, Whitehead Member David Sabatini says this...

The work has implications for cancer drug development Scientists at The Scripps Research Institute (TSRI) have determined how two proteins help create organelles, or specialized subunits within a cell, that play a vital role in maintaining cell health. This discovery opens the door for research on substances that could interfere with the formation of these organelles and lead to new therapies for cancer. The study, published online ahead of print on December 2, 2012, by the journal...

Bacteria that cause the tick-borne disease anaplasmosis in humans create their own food supply by hijacking a process in host cells that normally should help kill the pathogenic bugs, scientists have found. This bacterium, Anaplasma phagocytophilum (Ap), secretes a protein that can start this process. The protein binds with another protein produced by white blood cells, and that connection creates compartments that siphon host-cell nutrients to feed the bacteria, enabling their growth...

Synthetic Membrane Channels Built Out Of DNA

Technische Universitaet Muenchen Nanotech structures mimic nature's way of tunneling through cell walls As reported in the journal Science, physicists at the Technische Universitaet Muenchen (TUM) and the University of Michigan have shown that synthetic membrane channels can be constructed through "DNA nanotechnology." This technique employs DNA molecules as programmable building materials for custom-designed, self-assembling, nanometer-scale structures. The researchers present evidence...

Genetic Mosaic Of DNA Revealed

redOrbit Staff & Wire Reports - Your Universe Online A new study of stem cells derived from skin tissue has challenged the commonly held notion that a person's cells all share the same DNA sequence, arguing instead that genetic variation may occur to a greater extent than experts had previously believed. Researchers at the Yale School of Medicine set out to challenge the theory that human cells are comprised of identical genetic material, and that a body's functions are governed by...

Yeast Mothers Sacrifice All For Their Babies

University of California - San Francisco UCSF discovery shows evolution at work in the laboratory A mother's willingness to sacrifice her own health and safety for the sake of her children is a common narrative across cultures — and by no means unique to humans alone. Female polar bears starve, dolphin mothers stop sleeping and some spider moms give themselves as lunch for their crawly babies' first meal. Now an unexpected discovery at the University of California, San...

Key To Controlling Fruit Ripening Could Be In The Functions Of Chloroplasts
2012-11-01 14:51:47

University of Leicester Biologists may have unearthed the potential to manipulate the functions of chloroplasts, the parts of plant cells responsible for photosynthesis. Researchers in the University of Leicester's Department of Biology discovered that chloroplasts are affected by the ubiquitin proteasome system (UPS) — a process which causes the breakdown of unwanted proteins in cells, previously thought to only act on central parts of the cell. As a result, the researchers...

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 &...
