Common worm provides insights into salmonella virulence
...indings could ultimately lead to improved drugs to prevent
or treat Salmonella infections. The researchers found four genes related to the Salmonella's "molecular syringe" that are required for the bacteria to have maximum potency in infecting the worm, known as Caenorhabditis elegans. The virulence factors ...

Gene expression ratio identifies risk of recurrence in breast cancer patients receiving tamoxifen
...n-blocking drugs have been used in recent years to prevent
hormone-sensitive breast tumors from recurring after surgery and to treat metastasis. More than 500,000 U.S. women currently take tamoxifen, making it the most frequently used drug of this class. The MGH and Arcturus research teams have collaborate...
