Scientists find a maturity gene in fly

...nt of normal length. Thummel concludes: "Our life cycle consists of embryonic development, growth, maturation, aging and then death. We have a good handle on how embryonic development and aging work at a molecular level. But the transition from growth to maturation is poorly understood. If we can study th...

MWG Biotech expands siMAX?siRNA portfolio with new scales, lengths and design tools

MSKCC researchers uncover structure of key protein complex in cells

... 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 identified ho...

Birds and bats sow tropical seeds

...tropical areas worldwide, leading to a destructive cycle of land fragmentation, habitat loss and -- even with replanting using wind-dispersed trees -- species loss. Howe and his colleagues will lease 16 land parcels in Veracruz located near or adjacent to forest remnants or UNAM's protected rainforest to ...

New study finds how cells with damaged DNA alert the immune system

...wn that when genetic abnormalities occur, the cell cycle is halted so that the cell has time to fix the damage before the DNA is replicated. If the damage is too severe for the cell to repair on its own, it can trigger cell death, a process known as apoptosis. "All of this is happening autonomously within...

Metal-containing compounds show promise as HIV weapon

...old key proteins in place as part of the infective cycle of HIV, preventing the proteases from working. Other advantages are that the compounds are stable and can be modified in many ways by attaching other strings of atoms to them. Further research may reveal that one modified version may be more stable ...

Costly breeding programs for endangered species pay off

...mperatures in incubators were altered on a 12-hour cycle based upon the high and low temperatures recorded in Houston that day. In both strategies, all breeding lines survived in captivity. In the "wild" setting, four of the inbred populations went extinct, compared to just one extinction for the MAI line...

California computer scientists double volume of data in NIH biotech repository

...rs, NCBI can make it an integral part of the build cycle for dbSNP," said NCBI's Stephen Sherry. "Every time there is a new release of polymorphism and human variation information in our database, our colleagues in California will be able to re-compute the haplotypes and tag SNPs." To underscore that point...

Plant genes identified that can form basis for crops better adapted to environmental conditions

...again. Therefore, it is also crucial that the cell cycle − the process that directs cell division − be under optimal control. Although the precise factors that underlie these processes and how they work together are virtually unknown, it has been quite clear that an enormous number of factors a...

Plants reveal a secret and bring researchers nearer a cleaner future

...been proposed in the process of photosynthesis - a cycle known as "Kok cycle"- but only four had been proved until recently. With the help of the ESRF, scientists have been able to identify the missing state, which is particularly important because it is directly involved in the molecular oxygen formation....

Mechanism for Epstein-Barr virus protein's role in blood cancers discovered

...V-related cancers. "Stopping this step in the life cycle of EBV could be a major potential target for the development of therapeutics for treating EBV-related B cell lymphomas," says Robertson. "This is especially important because a large percentage of patients are non-responsive to the current frontline ...

Lethal needle blight epidemic may be related to climate change

...tuted a smoking gun, because D. septosporum's life cycle depends on summer moisture for spore distribution. The increase in precipitation had no clear link to a known climatic oscillation that might have explained it, and the authors conclude that it is most likely related to a directional climate trend. ...

Fruit fly research set to revolutionize study of birth defects

"This study shows that MTX treatment has multiple targets," says Affleck. "And this provides us with a novel invertebrate model for the st...

FSU biologists describe key role of signal-transcribing gene during cell cycle
