The broad use of the Gal4 is in yeast two-hybrid screening to screen or to assay protein-protein interactions in eukaryotic cells from yeast to human. In the GAL4/UAS system, the Gal4 protein and Gal4 upstream activating region (UAS) are used to study the gene expression and function in organisms such as the fruit fly. [3]
The reporter gene used in the system is the HIS1 gene. When proteins interact, the cells will be able to grow on medium lacking histidine due to the activation of the HIS1 reporter gene. [11] [38] Several interactions have thus far been detected using this system in a low scale set up. [38] [125] A first high-throughput screening has also been ...
Mutations in other genes can also have an indirect dependence on the TREX complex and lead to disease, including familial amyotrophic lateral sclerosis(ALS). ALS is a rare neurodegenerative disease that leads to the death of motor neurons in the brain, resulting in the loss of voluntary movement. [ 39 ]

Candida species tend to be the culprit of most fungal infections and can cause both systemic and superficial infection. [6] Th1-type cell-mediated immunity (CMI) is required for clearance of a fungal infection. Candida albicans is a kind of diploid yeast that commonly occurs among the human gut microflora. C. albicans is an opportunistic ...
What experts say about the connection between the immune system and autoimmune disorders like MS, lupus, arthritis, and others.
Candida antigens can be presented to antigen-presenting cells, which may trigger cytokine production and activate lymphocytes and neutrophils that then cause inflammation and edema. [23] [24] PRA1 gene (pH-regulated antigen) is strongly up-regulated during vaginal infections, which correlates with inflammation. [25]
As of 2010 a model of genetic interactions is most comprehensive yet to be constructed, containing "the interaction profiles for ~75% of all genes in the Budding yeast". [60] This model was made from 5.4 million two-gene comparisons in which a double gene knockout for each combination of the genes studied was performed.
