Targeting Heat Shock 27 Kda Protein Induces Androgen Receptor Degradation, Yaxin Li

Glioblastoma (GBM) is the most common and aggressive brain tumor, with very poor prognosis. Androgen receptor (AR) plays a significant role in the progression of GBM, and anti-androgen agents have the potential to be used for the treatment of GBM. However, AR mutation commonly happens in GBM, which makes the anti-androgen agents less effective. Heat shock 27 kDa protein (HSP27) is a well-documented chaperone protein to stabilize AR. Inhibition of HSP27 results in AR degradation regardless the mutation status of AR, which makes HSP27 a good target to abolish AR in GBM. Identified compound I ((N-(3-((2,5-dimethoxybenzyl)oxy)-4-(methylsulfonamido) phenyl)-4-methoxybenzamide) inhibits GBM cell …
Mechanisms Of Telomere Maintenance In Trypanosoma Brucei, M A G G. Rabbani
Mechanisms Of Telomere Maintenance In Trypanosoma Brucei, M A G G. Rabbani
ETD Archive
Telomeres are a nucleoprotein structure at the end of the chromosome and are essential for genome integrity and chromosome stability. Telomere lengths are primarily maintained by a telomerase-mediated pathway but can be maintained by a homologous recombination-mediated pathway. However, detailed mechanisms of telomere maintenance are still unclear in many eukaryotes, including an important human pathogen, Trypanosoma brucei. Telomeres can be elongated by telomerase in T. brucei, a causative agent of fatal sleeping sickness in humans and nagana in cattle. T. brucei evades host immune response by regularly switching its major surface antigen, variant surface glycoprotein (VSG), a process known as …

Project I: Chemotherapeutic drugs have many side effects that are undesirable and are highly toxic. Therefore, there is a growing need for the development of drugs with enhanced efficacy, specificity, and potency to provide cancer patients with a better prognosis. It was discovered that a member of the Receptor Tyrosine Kinase family, EphA2, may prove to be a viable target in developing anti-cancer agents. In the presence of its ligand, EphA2 receptor is responsible for apoptotic and anti-migratory activity. However, in the absence of ligand, EphA2 is able to stimulate cell migration and therefore tumorigenic activity. These conflicting roles of …
Quantitative Analysis Of Bleomycin In Rat Plasma By Lc-Ms/Ms, Huawen Li
Quantitative Analysis Of Bleomycin In Rat Plasma By Lc-Ms/Ms, Huawen Li

Bleomycin is the most commonly used compound in its group of antineoplastic drugs. It works on tumor cells by single and double stranded DNA cleavage after its activation, in which it blocks tumor cells’ DNA replication or transcription activities to inhibit tumor cells’ growth. Bleomycin sulfate (Blenoxane) is the most popular preparation used in clinical research, and contains Bleomycin fractions of A2 and B2, which causes difficulties in quantitative analysis. This work uses the metal chelating property of Bleomycin as an advantage to simplify and improve sensitivity of existing quantitative methods. Copper was spiked in excess to plasma samples, followed …

Il-17 Drives Copper Uptake And Activation Of Growth Pathways In Colorectal Cancer Cells In A Steap4-Dependent Manner, Evan Martin

Colorectal cancer is a disease characterized by abnormal, invasive cell growth beginning in the colon or rectum. The third most common type of cancer worldwide, approximately one million new cases of the disease are diagnosed across the globe annually, resulting in an estimated 700,000+ deaths. One major risk factor associated with development of colorectal cancer is the presence of chronic inflammation in the large intestine, also known as colitis. Inflammation is a complex immune response against harmful stimuli, characterized by symptoms including heat, redness, swelling and pain. One important molecular mediator of this process is interleukin 17 (IL-17), a pro-inflammatory …
