Nucleotide requirement and effects of fatty acids on protein synthesis and degradation in brown adipose tissue mitochondria.

abstract：:The rat atrium contains a potent natriuretic factor which appears to inhibit the sodium reabsorption in the collecting tubules of the kidneys. We examined the effects of the injection of partially purified atrial natriuretic factor (ANF) and synthetic ANF (8-33) into rats with simultaneous infusions of dextrose or apr...
