Description
Gluten is another name for natural proteins found in wheat, rye, barley and other grains that are commonly found in most boxed, pre-made, or baked items. However, the number of people diagnosed with Celiac's Disease, Non-Celiac Gluten Sensitivity, or Wheat Allergy has risen dramatically over the past few decades. In fact, the Gluten-Free Market is estimated to be worth 6.6 billion dollars by 2017. Therefore, this cookbook was made to provide quick, easy, and diverse recipes for people unable to ingest gluten without hurting their wallets.

Description
The human hairless gene (HR) encodes a 130 kDa transcription factor that is primarily expressed in the brain and skin. In the promoter and 5'-untranslated regions (5'-UTR) of HR, there are three putative consensus p53 responsive elements (p53RE). p53 is a tumor suppressor protein that regulates cell proliferation, apoptosis, and other cell functions. The p53 protein, a known tumor suppressor, acts as a transcription factor and binds to DNA p53REs to activate or repress transcription of the target gene. In general, the p53 binding sequence is 5'-RRRCWWGYYY-3' where W is A or T, and R and Y are purines or pyrimidines, respectively. However, even if the p53 binding sequence does not match the consensus sequence, p53 protein might still be able to bind to the response element. The intent of this investigation was to identify and characterize the p53REs in the promoter and 5'-UTR of HR. If the three p53REs (p53RE1, p53RE2, and p53RE3) are functional, then p53 can bind there and might regulate HR gene expression. The first aim for this thesis was to clone the putative p53REs into a luciferase reporter and to characterize the transcription of these p53REs in glioblastoma (U87 MG) and human embryonic kidney (HEK293) cell lines. Through the transactivation assay, it was discovered that p53REs 2 and 3 were functional in HEK293, but none of the response elements were functional in U87 MG. Since p53 displayed a different regulatory capacity of HR expression in HEK293 and U87 MG cells, the second aim was to verify whether the p53REs are mutated in GBM U87 MG cells by genomic DNA sequencing.

Description
The major goal of this large project is to develop a Recognition Tunneling Nanopore (RTP) device that will be used for determining the structure of glycosaminoglycans (GAGs). The RTP device is composed of a recognition tunneling junction that is embedded in a nanopore. In order to translocate the GAG molecule through the nanopore, researchers have designed a scheme in which the GAG molecule of interest will be attached to the 5’ end of a DNA primer (figure 1) and the DNA primer will be extended by a biotinylated Φ29 DNA polymerase that is anchored in the nanoslit using streptavidin. This research project specifically is part of a larger project with the main goal of comparing the activity of the wild-type Φ29 DNA polymerase which I have expressed and purified with the mutated Φ29 DNA polymerase devoid of 3’ - 5’ exonuclease activity which was made by Dr. Deng.
