Human HNF4A adenoviral particles

The hepatocyte nuclear factor 4 alpha (HNF4A) gene encodes a transcription factor that plays a key role in regulating gene networks related to metabolism, development, and cell differentiation. As a member of the nuclear receptor superfamily, HNF4A is highly expressed in the liver, pancreas, kidney, and intestine, and regulates the expression of genes critical for glucose homeostasis, lipid metabolism, and bile acid synthesis. Mutations in the HNF4A gene are associated with maturity-onset diabetes of the young (MODY1), highlighting its importance in maintaining metabolic balance. In addition, HNF4A is essential for embryonic development, especially during the formation of liver and pancreatic tissue. Its ability to modulate epigenetic states and interact with co-regulators makes it a key player in cellular reprogramming and disease modeling.

Human HNF4A adenoviral particles are genetically engineered viral vectors designed to efficiently deliver the HNF4A gene to target cells. These particles exploit the natural infectivity of adenoviruses to achieve stable and transient gene expression, making them ideal for research applications that require rapid and efficient protein production. Adenoviral systems are particularly advantageous due to their broad tropism, enabling transduction in both dividing and non-dividing cells, including primary hepatocytes and stem cells. Researchers have used HNF4A adenoviral particles to study metabolic pathways, explore mechanisms of diabetes, or reprogram cells to a hepatocyte-like phenotype. They are also used to explore gene therapy for liver disease and metabolic syndrome.
