Gene expression

CRISPR Cas9 CRISPR Cas9 is a gene editing tool that can be used to edit, delete, and change parts of the genome. What makes CRISPR Cas9 different from other gene editing techniques such as Zinc Finger Nuclease (ZFN) or Transcription Activator-Like Effector Nucleases (TALEN) is its targeting efficiency ability. For example, ZFNs and TALENs could only reach targeting efficiencies from 1% to 50% in human cells. On the other hand, CRISPR Cas9 had a much higher rate at greater than 70% in Zebrafish…

by the Ventura lab to investigate the potential role of non-sense mediated decay and of the UPF1 gene in pancreatic ASC. Background At the core of this grant proposal is the recent discovery that 78.2%…

Drosophila that express parkin under the yeast UAS enhancers controls. Only when parkin and α-synucein are co-expressed is the climbing ability of the fly loss prematurely, due to the dopaminergic neurons suppressing the α-synuclein. On the contrary- expression of parkin alone causes little repercussions or consequences-although when directed to the eye counteracts the α-s degeneration of ommatidial arrangement. PD-like symptoms in the α-synuclein dependent Drosophila are suppressed when parkin…

that their study was constrained by the limited number of samples with appropriately preserved DNA and by the fact that mitochondrial DNA is inherently sex linked. They thus theorised that Neandertals may have possible contributed a small number of genes to contemporary humans, which may have been lost to genetic drift. Ghirotto, S., Tassi, F., Benazzo, A. & Barbujani, G. (2011). No evidence of Neandertal admixture in the mitochondrial genomes of early European modern humans and contemporary…

Homework 4 1. A. Hcd19Tg is Human CD-19-Transgenic mice overexpressing CD19 which is a B-lymphocyte antigen present on all B cells. It is a transgenic model of human gene CD-19 introduced into the mice for research studying the effect of CD19 related to B-cell related immunological response B. CD1dloCD5+ is a rare phenotype of Regulatory B cells found in spleen of normal and autoimmune mice producing IL-10 and hence also called the B10 cells. As this phenotype is identifies to regulate T cell…

genetic disorders and can allow the parents to make a decision based on the results (terminate, etc) making gene modification useless (http://www.advancedfertility.com). This allows parents to decide if they want to have the child or try again. Genetically modified babies also cause a multitude of issues. The babies would be considered “fake” by some people because they don’t share their parent’s genes because they were edited. This can also cause paternity test issues since neither of the…

given in pH 6.2 column in Table 2. Approach 3: Pigment initiated termination. Looking at the results of Approach 2 where the delayed termination was seen to be more effective , we decided to couple it with the detection module such that the killer gene is activated when a certain concentration of pigment is…

the human body. An autoimmune disorder is a condition where the antibodies of the immune system attack the healthy cells and tissues. Since they’re both autoimmune disorders, the possibility of them being related genetically increases due to same genes to trigger the immune response. Scientist are investigating the possibility of these two disorders having a genetic similarity, causing individuals who have celiac to be more susceptible to type 1 diabetes and vice versa. Scientist and…

learned to manipulate gene expression by only allowing less hostile breeds to reproduce. Although this method of changing behavioral gene expression has much less control on a specific genomic sequence, it still provides us an insight as to how long we’ve been manipulating genes for: approximately 12,000 years (Lange). Subsequent to a more in depth knowledge of DNA, genetic modification became…

can result in couples who struggle to pass on genes to do so. This may halter the process of natural selection and increase biodiversity. It changes the genetic composition by having the choice of what characteristics’. E.g. few selected genes become common in the heard and other alleles are lost. This could be significant as a resistant for a disease can potentially be…
