Many adult humans lack the lactase enzyme, which has the same function as β-galactosidase, so they are not able to properly digest dairy products. β-Galactose is used in such dairy products as yogurt, sour cream, and some cheeses which are treated with the enzyme to break down any lactose before human consumption. In recent years, β ...
This observation was first published by Otto Heinrich Warburg, [2] who was awarded the 1931 Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme". [3] The existence of the Warburg effect has fuelled popular misconceptions that cancer can be treated by dietary reductions in sugar and ...
[47] [48] This study shows that L. lactis NZ9000 can inhibit HT-29 proliferation and induce cell apoptosis by itself. The success of this strain's construction helped to inhibit migration and expansion of cancer cells, showing that the secretion properties of L. lactis of this particular peptide may serve as a new tool for cancer therapy in the ...
Medical research for cancer begins much like research for any disease. In organized studies of new treatments for cancer, the pre-clinical development of drugs, devices, and techniques begins in laboratories, either with isolated cells or in small animals, most commonly rats or mice. In other cases, the proposed treatment for cancer is already ...
Saccharomyces cerevisiae, the yeast commonly used as baker's yeast. Gradation marks are 1 μm apart.. Baker yeast is the common name for the strains of yeast commonly used in baking bread and other bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ...
A yeast expression platform is a strain of yeast used to produce large amounts of proteins, sugars or other compounds for research or industrial uses. While yeast are often more resource-intensive to maintain than bacteria, certain products can only be produced by eukaryotic cells like yeast, necessitating use of a yeast expression platform.
There is no lactose to inhibit the repressor, so the repressor binds to the operator, which obstructs the RNA polymerase from binding to the promoter and making lactase. Bottom: The gene is turned on. Lactose is inhibiting the repressor, allowing the RNA polymerase to bind with the promoter, and express the genes, which synthesize lactase.
The group of short peptides found there have shown antimicrobial properties such as their strength against viruses and other cell types, including cancer cells. [27] There is also some evidence supporting the use of a symbiotic gel (containing L. acidophilus) in treating gastrointestinal symptoms in patients who had received a hemodialysis ...
