概括
在肥胖个体中,观察到表皮生长因子受体4 (ERBB4) 和神经调节素4 (NRG4) mRNA的水平较低. 这些发现表明,它可能在肝脂代谢中发挥作用,与非酒精性脂肪性肝病 (NAFLD) 不同.

背景情况:
- 皮表皮生长因子受体4 (ERBB4) 和神经调节素4 (NRG4) 在小鼠模型中显示有望降低肥胖症.
- 它们在人类非酒精性脂肪性肝病 (NAFLD) 中的作用在很大程度上仍未被探索.
- 这项研究研究了肥胖,2型糖尿病和NAFLD患者的ERBB4和NRG4.
研究的目的:

01:31Transducer Mechanism: Nuclear Receptors
1.2K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

13.2K
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...

01:31Internal Receptors
68.1K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
