We already know that miRNAs are involved in cancer and stem cell biology." Investigators were initially surprised to find that miRNAs affected only a small fraction of expressed genes withi...

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

...We believe the specific cell-to-cell signaling and dysfunction observed in fruit flies is applicable to mammals, which also possess genes Notch and Cut," said Deng. The researchers traced the journey of transmissions originating from Notch ?? which carries information gleaned from other cells ?? following the s...

Lack of key enzyme associated with development of rare tumor

...esearchers wrote that drugs used to treat erectile dysfunction interfere with the functioning of PDE11A. The researchers noted that PDE11A "is partially inhibited" by the drug tadalafil and "weakly" inhibited by sildenafil. They added that there are no reports in the medical literature of malfunctioning adrena...

New study shows antibiotic may protect the heart

...nd his colleagues have studied a class of erectile dysfunction drug known as phosphodiesterase-5 inhibitors as part of ongoing research into heart protection. The team first investigated Viagra®, generically known as sildenafil, and more recently, Levitra®, generically known as vardenafil, and found that both co...
