What happens when breast cancer spreads to the lungs
by CORDIS Credit: Explode, Shutterstock When cancer cells break away from the original tumor in metastatic—stage IV—breast cancer, they usually spread to the bones, liver or lungs. A new study, associated with the MetEpiStem project, describes what happens to metastatic breast cancer cells when they migrate from the primary site in the breast to soft...

Shift work increases the severity of strokes later in life
by Lindsey Hendrix, Texas A&M University Credit: CC0 Public Domain As most Americans wind down for bed, 15 million people are just clocking into work. These hospital workers, emergency responders, factory operators and others are among the 20 percent of the world’s population who do shift work. Their different sleep-wake cycle elevates their risk for...
Finding the triggers of inflammation
by Hudson Institute of Medical Research TLR-induced inflammasome priming triggers IL-1β and NLRP3 ubiquitylation. a BMDMs were primed with Lipopolysaccharide (LPS, 50 ng/ml) for up to 8 h (hr) and ubiquitylated (Ub.) proteins were isolated from cell lysates by Tandem Ubiquitin Binding Entity (TUBE) purification. Immunoblots were performed on cell lysates (input) and purified ubiquitylated proteins (TUBEs) for the...
Non-invasive shockwave treatment is ‘highly effective’ for moderate erectile dysfunction
by Wolters Kluwer Health Credit: CC0 Public Domain For men with moderate erectile dysfunction (ED), a non-invasive technique called low-intensity shockwave therapy (LiST) leads to significant improvement in sexual function, concludes a clinical trial in the Journal of Urology. “Our findings suggest LiST is highly effective and safe in patients with moderate vasculogenic ED,” write Nikolaos...

Global team of scientists discover new gene causing severe neurodevelopmental delays
by Nadine A Yehya, UC Davis Credit: Unsplash/CC0 Public Domain An international team of researchers led by UC Davis geneticist Suma Shankar has discovered a new gene implicated in a neurodevelopmental condition called DPH5-related diphthamide-deficiency syndrome. The syndrome is caused by DPH5 gene variants that may lead to embryonic death or profound neurodevelopmental delays. Findings...
