Effect of nutritional factors and cortisol on tyrosine aminotransferase activity in liver of brook trout, Salvelinus fontinalis Mitchill

Comparative Biochemistry and Physiology. B, Comparative Biochemistry
S J Whiting, A J Wiggs


1. Starvation for over 50 days increased the activity of Tyrosine aminotransferase (TAT) from brook trout liver and decreased liver glycogen. 2. Cortisol (6-40 mg/100 g body wt) increased TAT activity, optimally 72 hr post-injection; liver glycogen response to cortisol was variable while tissue water either increased or remained constant. 3. Fish fed high-protein/low-carbohydrate had greater TAT activity than fish fed low-protein/high carbohydrate. There was food-induced peak of activity indicating a "diurnal rhythm" analogous to that of rat TAT. 4. TAT activity in brook trout appears to be correlated with protein catabolism.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration

HLA Genetic Variation

HLA genetic variation has been found to confer risk for a wide variety of diseases. Identifying these associations and understanding their molecular mechanisms is ongoing and holds promise for the development of therapeutics. Find the latest research on HLA genetic variation here.
