Researchers develop mouse model of neurofibromatosis

A mouse tumor model of neurofibromatosis type 1 has been developed, allowing researchers to study the genetic lesions that lead to malignant tumor formation. The study found that mutations in both NF-1 and p53 genes accelerate tumor growth, providing a potential target for new treatments.

Neurological disorder inspired European dancing tradition

A historical review suggests that European dancing traditions may have roots in a neurological disorder causing dance-like movements.

Researchers develop mouse models of neurofibromatosis

The researchers created mouse models with benign and malignant NF1-related tumors to study the disease. The studies revealed that neurofibroma tumors invariably include cells lacking the NF1 gene, and that anti-Ras drugs might be useful in treating NF1.

Male unemployment levels affect birthweight

Research reveals a correlation between male unemployment and lower birthweights in Norway and Sweden. The study suggests that the indirect effects of unemployment on stressed partners and community stress can lead to increased risk of preterm delivery, low infant birthweight, and subsequent infant illness.
