Additionally, HLA-B27 positive AS patients expressed the Bcl11b mRNA slightly lower relative to healthy controls (0.40 times down-regulated; P = 0.021, Figure……...). On the other side, HLA-B27-negative AS patients were expressing the Bcl11b mRNA higher, however insignificant (0.51 times up-regulated; P = 0.23, Figure….) than healthy individuals. Methylation level of Bcl11b promoter in PBMCs The methylation status of AS patients and healthy controls has been depicted in Table ……., Figure ……...…

Transfer RNA Transfer RNA (tRNA) is a crucial component in Protein Synthesis. It serves as an adaptor molecule between the codon, the three nucleic acids and the amino acid after which a specific protein will be synthesized. It is the intermediate in Protein Synthesis which interprets the genetic code. Without tRNA, translation in prokaryotes or eukaryotes could not take place. Common Features of tRNA Molecule Each amino acid has at least one tRNA molecule. Therefore, these tRNA molecules have…

the structure and function of G- protein in relation to it’s regulation and the post transcriptional processes associated with gene expression. The lab uses Translation Elongation apparatus found in yeast to investigate these processes. The components of these elongation factors are important targets for antibacterial and antifungal drugs such that improper expressions and mutations in these factors can cause several forms of Carcinoma; a type of cancer that develops from epithelial cells or…

The key scientific issues being discussed right now about GMOs (genetically modified organisms) are that are these transgenic crops safe and is it ethical? Transgenic crops are crops that have a gene in them that has been genetically modified not through pollination but through someone artificially inserting the gene in the seed. Ethics play a big role in genetic engineering so GMOs have a lot of ethics go in them before anything is actually done to the crop itself. That being said not all GMOs…

Homeobox, or HOX genes are genes that determine organ and limb formation during early embryonic development. Frances R. Goodman writes in Limb Malformations and the Human HOX Genes that humans have 39 HOX genes that are organized into four clusters that have their own roles in the development of the central nervous system, axial skeleton, genitalia, and limbs. HOX genes were first discovered through mutation in fruit flies, which led to further research with HOX genes in other vertebrates. The…

The title of the video, “Ghost in your Genes”, is very appropriately titled because it discussed the various appearances of phenotypic differences among organisms with identical genomes. In the mid to late 1900s, scientists were convinced that DNA sequences were solely responsible for every trait evident in organisms. After the human genome experiment, which involved compiling and analyzing genomes of thousands of different people, it was determined that humans have around 25,000 genes, far…

identified in different cancer types, including medulloblastoma (MB). Notably, overexpression of minichromosome maintenance (MCM) proteins 2, 3 and 7 is associated with migration and invasion in MB. In this study, we provide a more comprehensive mRNA expression profiling of a larger set of pre-RC elements in different MB cell lines and tumor tissues. Our results show that pre-RC elements are significantly overexpressed in the majority of MB cell lines and tumor tissues. Notably, MCM10 shows the…

in the retinal pigmented epithelium. Transmission by the eye is performed by the retina and the optic nerve. Lastly, display is specific to the visual cortex (Cvekl and Ashery-Padan 2014). Clearly, a lot of regulation must take place within the expression of genes in order for the eye to develop all of…

which results in a valine to glutamate substitution at residue 600. This mutated form of the BRAF gene has been found to disrupt the hydrophobic interactions in between the activation loop and the ATP binding site, which results in a constitutive expression of MEK, and ultimately transcription factors that perpetuate cellular differentiation, cellular proliferation, and cellular survival7. Research has determined that these mutations involving either the RET/PTC and BRAF mutation do not…

The apterous gene mutations is a recessive trait that is inherited causing a varying phenotypes such as different wing deformities. Other phenotypes observed are the decrease in life span and female sterility. Ap is required to regulate gene expression needed for the development of Drosophila wings and haltere discs. Decreased ap activity due to the overexpression of dLMO results in wing mutations. The phenotypes displayed in apterous mutants are places them at a disadvantage compared to wild…
