Genetic testing for patients at risk of hereditary breast and ovarian cancer.

The field of cancer genetic testing has made great advances in correctly identifying patients at risk for hereditary cancer syndromes. These tests, used during a genetic consultation, promote earlier detection of cancer and potentially increase survival. Despite these advancements, a large number of persons at risk for BRCA1/2 mutations remain untested due to a shortage of genetic counselors and lack of clinician knowledge on how to properly screen, identify, and refer patients to genetic counseling.

Therapeutic modulation of the bile acid pool by Cyp8b1 knockdown protects against nonalcoholic fatty liver disease in mice.

Bile acids (BAs) are surfactant molecules that regulate the intestinal absorption of lipids. Thus, the modulation of BAs represents a potential therapy for nonalcoholic fatty liver disease (NAFLD), which is characterized by hepatic accumulation of fat and is a major cause of liver disease worldwide. Cyp8b1 is a critical modulator of the hydrophobicity index of the BA pool.
