The Effects Of Vitamin C On Cancer: A Cellular And Epidemiological Perspective, Amy C. Mclaughlin Apr 2013

The Effects Of Vitamin C On Cancer: A Cellular And Epidemiological Perspective, Amy C. Mclaughlin

Senior Honors Theses

While vitamin C has been proven to benefit the immune system during acute infections, there are now many studies to support the findings that vitamin C may also contribute to more effective chemotherapy and lessened damage on the body as a result of chemotherapy. This thesis investigates the impact of vitamin C on many components of cancer such as C-reactive protein, interleukins, reactive oxygen species, and many types of antioxidants and examines vitamin C's ability to inhibit or promote these agents' functions in the body. In addition, this thesis evaluates the ability of vitamin C to keep tumor cells from …

Chloroform Fraction Of Centratherum Anthelminticum (L.) Seed Inhibits Tumor Necrosis Factor Alpha And Exhibits Pleotropic Bioactivities: Inhibitory Role In Human Tumor Cells, Dr Syam Mohan

Syam Mohan

We investigated the antioxidant potential, cytotoxic effect, and TNF-α inhibition activity with NF-κB activation response in a chloroformfraction of Centratherum anthelminticum seeds (CACF). The antioxidant property of CACF was evaluated with DPPH, ORAC, and FRAP assays, which demonstrated significant antioxidant activity. The cytotoxicity of CACF was tested using theMTT assay; CACF effective inhibitory concentrations (IC50) for A549, PC-3, MCF-7, and WRL-68 cells were 31.42 ± 5.4, 22.61 ± 1.7, 8.1±0.9, and 54.93±8.3 μg/mL, respectively. CACF effectively and dose-dependently inhibited TNF-α release, in vitro and in vivo. CACF inhibited TNF-α secretion in stimulated RAW264.7macrophage supernatants with an IC50 of 0.012 μg/mL, …

In Vitro Anti-Inflammatory, Cytotoxic And Antioxidant Activities Of Boesenbergin A, A Chalcone Isolated From Boesenbergia Rotunda (L.) (Fingerroot), Dr Syam Mohan

Syam Mohan

The current in vitro study was designed to investigate the anti-inflammatory, cytotoxic and antioxidant activities of boesenbergin A (BA), a chalcone derivative of known structure isolated from Boesenbergia rotunda. Human hepatocellular carcinoma (HepG2), colon adenocarcinoma (HT-29), non-small cell lung cancer (A549), prostate adenocarcinoma (PC3), and normal hepatic cells (WRL-68) were used to evaluate the cytotoxicity of BA using the MTT assay. The antioxidant activity of BA was assessed by the ORAC assay and compared to quercetin as a standard reference antioxidant. ORAC results are reported as the equivalent concentration of Trolox that produces the same level of antioxidant activity as …

Synthesis Of Chalcones With Anticancer Activities., Dr Syam Mohan Jan 2012

Synthesis Of Chalcones With Anticancer Activities., Dr Syam Mohan

Syam Mohan

Several chalcones were synthesized and their in vitro cytotoxicity against various human cell lines, including human breast adenocarcinoma cell line MCF-7, human lung adenocarcinoma cell line A549, human prostate cancer cell line PC3, human adenocarcinoma cell line HT-29 (colorectal cancer) and human normal liver cell line WRL-68 was evaluated. Most of the compounds being active cytotoxic agents, four of them with minimal IC50 values were chosen and studied in detail with MCF-7 cells. The compounds 1, 5, 23, and 25 were capable in eliciting apoptosis in MCF-7 cells as shown by multiparameter cytotoxicity assay and caspase-3/7, -8, and -9 activities …

Cucurbitacin L 2-O- Glucoside Demonstrates Apoptogenesis In Colon Adenocarcinoma Cells (Ht-29): Involvement Of Reactive Oxygen And Nitrogen Species Regulation, Dr Syam Mohan Jan 2012

Cucurbitacin L 2-O- Glucoside Demonstrates Apoptogenesis In Colon Adenocarcinoma Cells (Ht-29): Involvement Of Reactive Oxygen And Nitrogen Species Regulation, Dr Syam Mohan

Syam Mohan

Emerging evidence suggests that reactive oxygen (ROS) and nitrogen (RNS) species can contribute to diverse signalling pathways of inflammatory and tumour cells. Cucurbitacins are a group of highly oxygenated triterpenes. Many plants used in folk medicine to treat cancer have been found to contain cucurbitacins displaying potentially important anti-inflammatory actions. The current study was designed to investigate the anti-ROS and -RNS effects of cucurbitacin L 2-O-β-glucoside (CLG) and the role of these signaling factors in the apoptogenic effects of CLG on human colon cancer cells (HT-29). This natural cucurbitacin was isolated purely from Citrullus lanatus var. citroides (Cucurbitaceae). The results …

Dentatin Induces Apoptosis In Prostate Cancer Cells Via Bcl-2, Bcl-Xl, Survivin Downregulation, Caspase-9, -3/7 Activation And Nf-Kb Inhibition., Dr Syam Mohan Jan 2012

Dentatin Induces Apoptosis In Prostate Cancer Cells Via Bcl-2, Bcl-Xl, Survivin Downregulation, Caspase-9, -3/7 Activation And Nf-Kb Inhibition., Dr Syam Mohan

Syam Mohan

This study was set to investigate antiproliferative potential of dentatin (a natural coumarin isolated from Clausena excavata Burm. F) against prostate cancer and to delineate the underlying mechanism of action. Treatment with dentatin dose-dependently inhibited cell growth of PC-3 and LNCaP prostate cancer cell lines, whereas it showed less cytotoxic effects on normal prostate epithelial cell line (RWPE-1). The inhibitory effect of dentatin on prostate cancer cell growth was due to induction of apoptosis as evidenced by Annexin V staining and cell shrinkage. We found that dentatin-mediated accumulation of reactive oxygen species (ROS) and downregulated expression levels of antiapoptotic molecules …

Identification Of Novel Molecular Targets Of Resveratrol In Colorectal Carcinogenesis, Nichelle Chantil Whitlock Dec 2011

Identification Of Novel Molecular Targets Of Resveratrol In Colorectal Carcinogenesis, Nichelle Chantil Whitlock

Doctoral Dissertations

Current research suggests resveratrol, a phytoalexin found predominately in grapes, may function as a chemopreventive and/or chemotherapeutic agent for various cancers, including colorectal cancer. However, the underlying mechanism(s) involved in these activities remain elusive. Thus, the objective of the studies discussed here sought to investigate the effect of resveratrol treatment on gene modulation in human colorectal cancer cells in order to identify and characterize novel molecular targets that contribute to the observed anticancer activities of resveratrol. Here, we identify activating transcription factor 3 (ATF3) and early growth response-1 (Egr-1) as novel targets of resveratrol and provide data to elucidate the …

The Growth Suppressing Effects Of Girinimbine On Hepg2 Involve Induction Of Apoptosis And Cell Cycle Arrest, Syam Mohan Aug 2011

The Growth Suppressing Effects Of Girinimbine On Hepg2 Involve Induction Of Apoptosis And Cell Cycle Arrest, Syam Mohan

Syam Mohan

Murraya koenigii is an edible herb widely used in folk medicine. Here we report that girinimbine, a carbazole alkaloid isolated from this plant, inhibited the growth and induced apoptosis in human hepatocellular carcinoma, HepG2 cells. The MTT and LDH assay results showed that girinimbine decreased cell viability and increased cytotoxicity in a dose-and time-dependent manner selectively. Girinimbine-treated HepG2 cells showed typical morphological features of apoptosis, as observed from normal inverted microscopy and Hoechst 33342 assay. Furthermore, girinimbine treatment resulted in DNA fragmentation and elevated levels of caspase-3 in HepG2 cells. Girinimbine treatment also displayed a time-dependent accumulation of the Sub-G(0)/G(1) …

Therapeutic Touch And Cancer Cells, Gloria A. Gronowicz Jan 2011

Therapeutic Touch And Cancer Cells, Gloria A. Gronowicz

UCHC Graduate School Masters Theses 2003 - 2010

Energy medicine therapies based on a human biofield have been practiced for thousands of years and can trace their origin in Ayurveda. Our goal was to determine if Therapeutic Touch (TT), a more recently developed energy medicine practice, had any effects on cancer cells. Previous work in our laboratory demonstrated that TT significantly increased the growth of normal human osteoblasts and increased the synthesis of bone matrix proteins and mineralization in cell culture. In this study as was practiced in our previous studies, TT was performed twice a week for 10 minutes and was compared to untreated cultures and 'placebo-treated" …
