A new plant-bacterial symbiotic mechanism promising for crop applications

...inside the plant by the root hairs. The finding raises the question as to what signalling pathway Bradyrhizodium might use to gain entry to the plant and set off nodulation. The first observation was that the bacteria did not penetrate the roots of its host-plant by the hairs. It took advantage of “c...

Potent possibilities for parasite attack

...so the identification of a CFAS gene in Leishmania raises the exciting possibility that some virulence factors are conserved between bacterial and eukaryotic intracellular pathogens," said Jeremy Mottram, a collaborator on the project who is a Professor in the Wellcome Centre for Molecular Parasitology at t...

Common treatment for methamphetamine overdose may damage brain cells

...Neuroscience . "This work in laboratory animals raises immediate concerns that a standard treatment for methamphetamine overdose in humans might worsen drug abuse-related brain injuries," says William Carlezon, PhD, at Harvard's McLean Hospital, who was not affiliated with the study. "A crucial next step...

Switching genes to overdrive improves muscular dystrophy symptoms in mice

...ty of genes under its control. Exercising a muscle raises PGC-1alpha levels, causing the formation of more mitochondria, the chemical power plants that create energy in cells. PGC-1alpha is also required for the normal operation of genes that control the development of neuromuscular junctions (NMJ) ?site...

Leukemia drug turns mini-molecules up, cancer genes down

...eating the disease. The study showed that ATRA raises the levels of three particular miRNAs in leukemia cells and that this rise coincides with a fall in activity of two important cancer-causing genes. The three are identified as miRNA-15b, miRNA-16-1 and let-7. Two of these, miRNA-15b and miRNA-16-...

Study suggests some drug resistance to influenza B medications

...B medications. “The report by Hatakeyama et al raises more questions than it answers, including questions about viral evolution, biological fitness, and transmissibility. But some facts are strikingly clear. Influenza B mutants with reduced sensitivity to neuraminidase inhibitors are circulating, and th...

"This raises the tantalizing prospect of three times the number of anticoagulants, and three times as many biomedically important developments in areas like protease inhibitors," said Mark Siddall of the American Museum of Natural History, who led the research te...

Cold sore virus might play role in Alzheimer's disease

...oncert with the herpes virus is new. "This work raises the question whether herpes in concert with ApoE-4 increases the risk of Alzheimer's disease. The data suggests that ApoE-4 may support the ability of HSV to be a more virulent pathogen," said Howard Federoff, M.D., Ph.D., the leader of the team and ...

Tumor-suppressor gene is critical for placenta development

... gene in mice. In humans, this gene, when mutated, raises the risk of a rare cancer of the eye called retinoblastoma. Two decades ago, it was identified as the first tumor-suppressor gene, a class of genes that protects cells from becoming cancerous. It has since been shown to be inactivated in many cancers...

"Whereas the conventional RPA complex acts elsewhere in the genome to raise a red flag to attract the attent...

Are journal rankings distorting science?

This week’s BMJ raises concerns over whether journal rankings (known as impact factors) are distorting publishing and science. The impact factor is a measure of the citations to papers in scientific journals. It was developed as a simple measure of quality and has become ...
