...ease, characterized by the development of multiple cysts in the kidney and end-stage renal disease in late middle age. Resulting from mutations in 1 of 2 genes, PKD1 or PKD2, previous studied have presupposed that the proteins encoded by these two genes, polycystin-1 and 2, physically interact to initiate ...

Arthritis: What Wnt wrong?

..., loss of protective cartilage, and growth of bone cysts (or osteophytes). Interestingly, Wnt-7b was strongly upregulated within joints at sites of disease manifestation: mainly in synovium of RA but in synovium, cartilage, osteophyte, and bone of OA. In addition, the findings that Wnt-7b was frequently...

Gene therapy works in mice to prevent blindness that strikes boys

...e retina. Without it, the layers separate and tiny cysts form, devastating the vision and often leading to blindness in about 1 of every 5,000 boys. UF researchers injected a healthy version of the human RS1 gene to the sub-retinal space of the right eyes of 15-day-old male mice, which, like boys with the...

Pall filtration technology verified to remove arsenic from drinking water

"The edges of tumors are where growth occurs, and they tell radiologists whether what they see is a tumor or not," Lucier said. "You ha...

Scientists find genetic pathway that could lead to drugs for kidney disease

...e disease is characterized by the proliferation of cysts that eventually debilitate the kidney, causing kidney failure in half of all patients by the time they reach age 50. Currently no treatment exists to prevent or slow cyst formation, and most ADPKD patients require kidney transplants or life-long dia...

'Diabetes gene' may be linked to polycystic ovary syndrome

...lycystic ovary syndrome (PCOS) occurs when ovarian cysts block a woman's normal ovulation and menstrual cycle. While the problem sounds straightforward, the disease is complex, born from both multiple genetic components and environmental factors. PCOS affects up to five percent of the female population, an...

Stanford discovery may help predict when toxoplasma can be deadly

Cats are the primary carriers of Toxoplasma, though they rarely exhibit symptoms. The significance of these newl...

Microwave oven can sterilize sponges, scrub pads
