A 2020 study explored the role of the glucose-alanine cycle in the metabolic reprogramming of Hepatocellular Carcinoma (HCC). [12] HCC is the most common form of liver cancer and the third most common cause of cancer-related deaths worldwide. [12]
Estimates based on most recent data suggest that each year there are 841,000 new liver cancer diagnoses and 782,000 deaths across the globe. [55] Liver cancer is the most common cancer in Egypt, the Gambia, Guinea, Mongolia, Cambodia, and Vietnam. [55] In terms of gender breakdown, globally liver cancer is more common in men than in women. [43 ...
[1]: 26 In most cases of a metabolic pathway, the product of one enzyme acts as the substrate for the next. However, side products are considered waste and removed from the cell. [2] Different metabolic pathways function in the position within a eukaryotic cell and the significance of the pathway in the given compartment of the cell. [3]
A convergence between phenotypic and metabolic state transitions that confers a survival advantage to cancer cells against clinically used drug combinations like taxanes and anthracyclines have also been reported while drug resistant cancer cells had increased activity of both the glycolytic and oxidative pathways and glucose flux through the ...
In cancer, there are several reprogrammed metabolic pathways that help cells survive when nutrients are scarce: Aerobic glycolysis, an increase in glycolytic flux, also known as the Warburg effect, allows glycolytic intermediates to supply subsidiary pathways to meet the metabolic demands of proliferating tumorigenic cells.

The liver is a major metabolic organ exclusively found in vertebrate animals, which performs many essential biological functions such as detoxification of the organism, and the synthesis of proteins and various other biochemicals necessary for digestion and growth.
Cytochrome P450 3A4 (abbreviated CYP3A4) (EC 1.14.13.97) is an important enzyme in the body, mainly found in the liver and in the intestine, which in humans is encoded by CYP3A4 gene. It oxidizes small foreign organic molecules ( xenobiotics ), such as toxins or drugs, so that they can be removed from the body.
The main regulator enzyme for this pathway is an enzyme called phosphoenolpyruvate carboxykinase (PEPC-K), which catalyzes the decarboxylation of oxaloacetate to phosphoenolpyruvate. [1] Glyceroneogenesis is observed mainly in adipose tissue, and in the liver. A significant biochemical pathway regulates cytosolic lipid levels.
