Virus Mimics Human Protein To Hijack Cell Division Machinery

Viruses are masters of deception, duping their host's cells into helping them grow and spread. A new study has found that human cytomegalovirus (HCMV) can mimic a common regulatory protein to hijack normal cell growth machinery, disrupting a cell's primary anti-cancer mechanism.

Public funding impacts progress of human embryonic stem cell research

Bolstered by supportive policies and public research dollars, the United Kingdom, Israel, China, Singapore and Australia are producing unusually large shares of human embryonic stem cell research, according to a report from the Georgia Institute of Technology in the June 2008 issue Cell Stem Cell. Aaron Levine, assistant professor of public policy and author of the book Cloning: A Beginner's Guide, studied how countries output of research papers related to human embryonic stem cell research compared to their output in less contentious fields. He found that even though the United States still puts out far more research in this field than any other single country, when one compares the amount of research in human embryonic stem cells to other forms of research in molecular biology and genetics, the U.

Getting Wise To Influenza Virus' Tricks: Imaging Of Influenza Virus Protein Opens Way To Design New Anti-viral Drugs

Influenza is currently a grave concern for governments and health organisations around the world. The worry is the potential for highly virulent bird flu strains, such as H5N1, to develop the ability to infect humans easily. New drugs and vaccines to halt the spread of the virus are badly needed. Now one of the tactics used by influenza virus to take over the machinery of infected cells has been laid bare by structural biologists at the European Molecular Biology Laboratory (EMBL) and the joint Unit of Virus Host-Cell Interaction of EMBL, the University Joseph Fourier and National Centre for Scientific Research (CNRS), in Grenoble, France.

Puzzle In The Control Of Cell Division Unraveled

A puzzle in the control of cell division, one of the most fundamental processes in all biology, has been unravelled by Oxford University researchers. Although the steps of cell division are familiar to all pupils studying biology in schools, the details of how cell division is controlled and errors avoided have still to be sorted out.

How Cells Communicate To Activate The Cell Division Machinery

A study performed by researchers at the Institute for Research in Biomedicine (IRB Barcelona) on the fruit fly, Drosophila melanogaster, unveils how distinct signaling pathways operate between neighboring cells in order to activate the cell proliferation machinery that results in the organized growth of the fly wing. The signaling pathways involved in this process are also conserved in humans, and when altered in diverse tissues give rise to the appearance of different types of cancer, including cancer of the colon and skin, and leukemia. The study has been undertaken in the Cell and Development Biology Laboratory headed by ICREA Research Professor, Marco Milán, at IRB Barcelona.

UK Approves Human-Pig Embryo Stem-Cell Harvest

An anonymous reader writes "British biologists have received government approval to create the world's first human stem cells from hybrid embryos, part pig, part human. The Warwick Medical School team, led by Justin St. John of the Clinical Sciences Research Institute, was granted the country's third animal-human embryo license from the Human Fertilisation and Embryology Authority, which goes into effect today (July 1)."

Policy environments may shape international progress of human embryonic stem cell research

Biomedical research may be substantially hampered by drawn out debates, conflicting legislation and restrictive policies. A new analysis, published by Cell Press in the June issue of Cell Stem Cell, investigates the influence of policy environments on the progression of research related to human embryonic stem cells (hESC) and offers new insight into the international development of this often ethically controversial field.

Quantum dots shed light on protein workload

Cell division is essential to life, but the mechanism by which emerging daughter cells organize and divvy up their genetic endowments is little understood. In a new study, researchers at the Univ. of Illinois and Columbia Univ. report on how a key motor protein orchestrates chromosome movements at a critical stage of cell division.

Stem Cell Sciences receives European Patent

Singapore, June 5, 2008: Stem Cell Sciences, a leading provider of cells and cell culture media to the burgeoning stem cell research market announced that the European Patent Office has granted a patent that protects its existing range of embryonic stem cell culture media. The media, marketed in Europe under the brands HEScGRO and EScGRO, are used in the culture of embryonic stem cells from human and mouse, respectively.

Deconstructing Green Fluorescent Protein

Green fluorescent protein (GFP) has been reassembled from two pieces, a large fragment 214 amino acids in length that is produced recombinantly (GFP 1−10) and a short synthetic peptide corresponding to the 11th stave of the β-barrel that is 16 amino acids long (synthetic GFP 11), following a system developed by Waldo and co-workers (Cabantous, S.; et al. Nat. Biotechnol. 2005, 23, 102−7) as an in vivo probe for protein association and folding. We demonstrate that the reassembled protein has identical absorption and excited-state proton transfer dynamics as a whole protein of the identical sequence. We show that the reassembled protein can be taken apart and the peptide replaced with a different synthetic peptide designed to perturb the chromophore absorption.

Dividing Cells Find Their Middle By Following A Protein contour Map

Self-organization keeps schools of fish, flocks of birds and colonies of termites in sync. It’s also, according to new research, the way cells regulate the final stage of cell division. Scientists at Rockefeller University have shown that a protein-chemistry-based contour map, which helps individual proteins locate the center of their cell without direction from a “master organizer,� is key to ensuring accurate division during mitosis.
