A Crispr Platform For Rapid And Inducible Genome Editing In Human Non-Small Cell Lung Cancer Cells, Lloyd Bartley

Posters-at-the-Capitol

Non-small cell lung cancer (NSCLC) accounts for about 85% of lung cancer, which is the leading cause of cancer death in the world. High mortality rate associated with NSCLC is partially attributed to the limited understanding of NSCLC as well as ineffective therapeutic treatments. The initiation and progression of NSCLC involves genetic changes leading to alterations in the control of tissue development and homeostatic maintenance. Better knowledge about these genetic abnormalities is imperative for developing new chemotherapeutic drugs for NSCLC. Recent research demonstrates that the expression of paraoxonase 2 (PON2), a lactonase/arylesterase with anti-oxidant properties, are markedly enhanced in cancer …

Development Of A Pd-L1 Pet Imaging Biomarker, Caleb Jack Bridgwater

Posters-at-the-Capitol

Immunotherapy strategies are very promising treatments for cancer patients. Specifically, Immune checkpoint inhibitor therapy focusing on the PD-1/PD-L1 pathway shows long-lasting positive results in many cancer patients. Unfortunately, not all the patients can benefit from this highly effective treatment. Hence, there is a great need for predictive biomarkers. Immunohistochemical (IHC) staining has been used as a way of predicting patient response, yet shows many problems. For example, IHC utilizes an invasive biopsy and sample fixing, which creates an incomplete and delayed picture of the patient’s biochemistry and the tumor microenvironment, consequently ignoring metastases.

Histone Deacetylation Is The Primary Epigenetic Mechanism For Silencing Of Tumor Suppressor Gene - Tissue Factor Pathway Inhibitor-2 In Hepatocellular Carcinoma Cells, Alisha Deshmukh, Shirish Barve

Posters-at-the-Capitol

Hepatocellular carcinoma (HCC) is the third leading cause of cancer related mortality worldwide. With a survival rate of less than 5 percent, a therapeutic treatment is desperately needed to manage this disease. Many epigenetic mechanisms that underlay HCC are being identified. A frequently silenced pathway tissue factor pathway inhibitor-2 (TFPI-2) is a critical tumor suppressor gene. In HCC, inactivation of TFPI-2 leads to tumor growth. Recent research indicated Fas L plays a major role in apoptosis as part of HCC. For the purposes of this study, the phytochemical Curcumin was explored to observe its possible effects on the epigenetic mechanisms …

Sirna Knock-Down Of Vav1 In Breast Cancer Cells: Effects On Pi3kinase And Akt, Tajai Sion-Milligan

Student Scholar Showcase

One in eight women in the United States will be diagnosed with breast cancer. Approximately 25-30% of these breast tumors will overexpress Human Epidermal Growth Factor Receptor 2 (HER2), associated with a worse prognosis and decreased survival rate. Stimulation of HER2 results in activation and production of many signaling molecules, ultimately resulting in increased cell division. Two of the downstream molecules activated are PI₃Kinase and, further downstream, the molecule Akt. Typically, overproduction and/or overactivation of PI₃Kinase can lead to oncogenesis. A molecule that may have a significant role in PI₃Kinase formation is VAV1. VAV1 …

Changes In The Proliferation And Gene Expression Of Huvecs In Response To Treatment With Plant Secondary Metabolites, Caleigh Howard

Seaver College Research And Scholarly Achievement Symposium

Medicinal plants have historically been a valuable source of new drugs, and Southern California possesses a rich collection of native plants which have been used as medicines by native people groups for thousands of years. Angiogenesis is the biological process of new blood-vessel growth from endothelial cells. It is an essential part of the wound-healing process, and increased angiogenesis has also been implicated in the growth of some types of cancerous tumors. In this study, extracts of the Southern Californian native plants Red shanks (Adenostoma sparsifolium) and the alkaloid extract of Jimson weed (Datura wrightii) were …
