Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer
The genome sequence of the parasitic amoeba Entamoeba histolytica, a leading cause of severe diarrheal disease in developing countries, includes an unexpectedly complex repertoire of sensory genes as well as a variety of bacterial-like genes that contribute to the organism's unique biology. The report, which appears in the February 24 issue of Nature, presents the first genome-wide study...Scientists document complex genomic events leading to the birth of new genes
A team of scientists led by Peer Bork, Ph.D., Senior Bioinformatics Scientist at the European Molecular Biology Laboratory, report today in the journal Genome Research that they have identified a new primate-specific gene family that spans about 10% of human chromosome 2. Comprised of eight family members, the RGP gene cluster may help to explain what sets apart humans and other primates from the...NYU, Rockefeller researchers find complexity of regulation by microRNA genes
Collaborating researchers at New York University and Rockefeller University have discovered that microRNA genes, which have recently been shown to have key roles in gene regulation, can team up and regulate target genes in mammals. MicroRNAs are a recently discovered large class of regulatory, non-coding genes, which bind to partially complementary sites in target messenger RNA to regulate their...Simple explanation for complex pattern of feather development
Biologists testing a mathematical model of the mechanism birds use to control the growth of complex feathers found that plumed feather structures involve the coordination of at least two genes that activate and that inhibit barb growth. "Understanding these mechanisms of feather growth gives a whole new perspective on the unique beauty of feathers," said Richard Prum, senior author on the...MSKCC researchers uncover structure of key protein complex in cells
Scientists at Memorial Sloan-Kettering Cancer Center (MSKCC) have uncovered the structure of a network of proteins that help regulate the life cycle of cells. Understanding the network's physical layout is an important step toward learning its precise function, and in finding ways to correct flaws in the system that could lead to cancer. Using x-ray crystallography, the researchers identif...Cell Wall Degrading Enzyme Complex Aspergillus sp. from Sigma-Aldrich

Rae 1-Nup98 are two protein complexes which is found to protect cell from transforming into aneuploidy state, which has an abnormal number of chromosomes leading to cell instability which leads to cancerous cells.// Professor Jan Van Deursen and his research team from Mayo Clinic have found that the two protein complex Rae1 – Nup98 have proofing capacity which maintains the euploidy state in the...Bush’s new prescription drug plan, a complex puzzle for the citizen
President Bush’s prescription drug plan came in to effect on Jan 1st, but the governors of many states like those of Pennsylvania, have trouble dealing with the issue//. The plan has been under study for more than a year but members of Medicare came to know about it when they received a booklet declaring the new prescription drug plan. The plan was very difficult to understand which pre...Human Complexity Can Be Attributed To Regulatory Sequence
Joseph M. Miano, Ph.D associate professor within the Cardiovascular Research Institute at the University of Rochester Medical Center said that // small regulatory DNA sequences control the genes and their functions. The researchers scanned the vast human DNA code to reveal 60 genes controlled by one such regulatory sequence. The findings of the study were published in the journal Geno...Mystery behind Complex Regional Pain Syndrome Unraveled
A new study said that complex regional pain syndrome is a neurological disorder caused by continuous nerve injury affecting small fibers which has the ability to sense pain. // This syndrome includes all the post-traumatic limb pain and other disturbances that continue even though the injury has healed. But the causes of the symptoms of the syndrome are unknown. This is due to...Scientists Explain Complex Darwinian Evolution
Scientists have managed to reconstruct a complex molecular system of Darwinian evolution for the first time by using new techniques for resurrecting// ancient genes. The research was led by Joe Thornton, assistant professor of biology at the University of Oregon's Center for Ecology and Evolutionary Biology, and will be published in the April 7 issue of SCIENCE.
