Dynamics of the NADP+ and NAD+ levels in the mycelium of P. nigricans Thom strains of varying productivity depending on the carbon source

I G Rogal'


The levels of NADP+ and NAD+ in the mycelium of the highly productive strain 117 and low productive strain B of P. nigricans were studied by the 2nd, 5th, 9th and 13th days of development on the mineral medium in the presence of glucose, succinate or acetate. It was found that at the beginning of the growth the levels of NADP+ in both strains in the presence of the same carbon source were the same, just as the levels of NAD+ in the presence of glucose or succinate. The same strain had different levels of NADP+ in the presence of different carbon sources. The levels of NAD+ depended on both the carbon source and the strain. In the presence of glucose both nucleotides were accumulated by the end of the culture development and in greater amounts by strain 117. In the presence of succinate the maximum levels were observed at the beginning of the culture growth, while in the presence of accetate the maximum levels were recorded by the end of the culture development (strain 117) and by the 19th day (strain B). It is supposed that NAD+ is transformed into adenylates in the fungi.

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.

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.
