Increasing The Efficacy Of Actinomycin D With Resveratrol In Aerodigestive Tract Cancers, Lukmon Morenikeji Raji

Theses, Dissertations and Capstones

Chemotherapy poses a significant challenge for cancer patients due to drug-associated toxicity, which often results from their effects on both healthy (normal) and cancerous cells. While various options aim to reduce toxicity and optimize beneficial effects, a comprehensive solution remains elusive. Cyclotherapy is one such approach developed to protect normal cells from the toxic effects of chemotherapy drugs. The basic principle underlying cyclotherapy is p53- dependent cell cycle arrest of normal cells while killing cancer cells via a p53-independent mechanism using a second drug. In our research, we investigated the inhibitory effects of a combination of two low-dose anticancer drugs, …

The Epigenetic Effects Of Omega-3 Fatty Acids In Diffuse Large B-Cell Lymphoma, Tanner Jeffrey Bakhshi

Theses, Dissertations and Capstones

Diffuse large B-cell lymphoma (DLBCL) is the most common type of lymphoma. It is an aggressive cancer, with 50-70% of patients diagnosed at an advanced stage and 30-50% of patients not cured by chemoimmunotherapy. DLBCL is almost always caused by genetic damage sustained during the germinal center (GC) reaction. The mechanisms that govern the GC reaction bear a striking resemblance to those that drive DLBCL. Genomic studies have shown that some of its most common mutations occur in genes that encode epigenetic modifiers, including the lysine (histone) acetyltransferases CREBBP and p300. These mutations prevent the acetylation of multiple histone residues, …

Potential Applications Of Capsaicinoids In Small Cell Lung Cancer Therapy, Jamie Rae Friedman

Theses, Dissertations and Capstones

Lung cancer continues to be the leading cause of cancer related mortality worldwide. Lung cancer is not a single disease but an umbrella that encompasses two major classifications, nonsmall cell lung cancer (NSCLC) and small cell lung cancer (SCLC). SCLC represents about 15- 20% of all lung cancer cases and is almost exclusively diagnosed in smokers. Typically, patients will respond very well to first line treatment, but face inevitable relapse. The fact that SCLC still carries a grim 5-year survival rate of less than 5% highlights the lack of advancement in treatment options to effectively improve patient response and survival. …
