概括
禁食和素食饮食影响了慢性淋巴细胞白血病 (CLL) 患者的绝对淋巴细胞计数 (ALC) 波动. 发现了一种独特的9个基因特征,可能与疾病的发展有关.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学

01:24Metabolic States of the Body: Fasting and Starvation
1.5K
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
