They found that blocking cleavage in the IGD diminished the loss of aggrecan and cartilage erosion in animals with osteoarthritis and inflammatory arthritis. In addition, this blockade appeared to stimulate...

New biotech company to commercialize novel UD gene-repair technology

...ber of these diseases are caused by a single-point mutation in a gene--which is like a spelling error, a single letter out of place, in its DNA code. The DNA nucleotide adenine (A), for example, might be replaced by guanine (G), cytosine (C) or thymidine (T). Kmiec and Parekh-Olmedo discovered a way to intr...

This initiat...

Study examines risk of soft tissue sarcomas in hereditary retinoblastoma survivors

... of soft tissue sarcomas is attributed both to the mutation in the RB-1 gene that causes retinoblastoma and to the radiation treatment that most retinoblastoma patients received when treated decades ago. Radiation is used less frequently today because of the risk of second cancers. Ruth A. Kleinerman, of the...
