In Vivo Assessment Of Safranal’S Novel Therapeutic Effects On Chemically Induced Hepatic Neoplasia, Ameera Ali M. Almansoori

Biology Theses

Chronic liver insult leads to fibrosis, which often ends up causing cirrhosis and most of the time that progresses into hepatic neoplasms (early Hepatocellular carcinoma; HCC). HCC is the fifth most common cancer, and the third cause of cancerrelated deaths. Chemotherapy is the most common treatment of cancer patients. HCC is however, chemo-resistant, and the side-effects of chemotherapy are typically exhausting to the patient. Sorafenib is the only anti-HCC drug approved by the U.S Food and Drug Administration. It is a multikinase inhibitor that blocks tumor cells proliferation and angiogenesis. Although sorafenib is successful treating early and mid HCC lesions, …

Anti-Colon Cancer Effect Of Origanum Majorana Essential Oil, Asma Nasser Rashed Alrashedi

Biology Theses

Plants have been shown to be an excellent source of new drugs, including anticancer agents. Origanum majorana commonly known as marjoram is a plant that is known to possess different therapeutic values including antioxidant andantimicrobial activities.

Our research team has previously tested the ethanolic extract of O. majorana on triple negative breast cancer and published the findings. The ethanolic extract promoted mitotic arrest at G2/M phase, induced apoptosis as well as inhibition of migration and metastasis. The promising potential of the ethanolic extract encouraged us to test the effects of O. majorana essential oil on human colon cancer cell lines. …

Study Of Cellular Activities In Response To Metal-Induced Apoptosis In Saccharomyces Cerevisiae Using Ftir, Rupa Koduru

Biology Theses

Saccharomyces cerevisiae exhibits an apoptotic response upon exposure to toxic metals such as cadmium (Cd) and copper (Cu). Preliminary findings indicate that this response is dependent –to some extent- on the presence of a fermentable carbon source, glucose. To investigate this dependency we monitored the apoptotic response to both metals in the presence and absence of glucose and have shown that glucose is absolutely necessary in order to induce apoptosis in yeast at least during the exposure to metal. We have also looked at the biochemical changes that are taking place in yeast when treated with Cd using Fourier Transform …

The C-Phycocyanin/Beta Protein Inhibits Cancer Cell Proliferation, Haizhen Wang

Biology Theses

C-Phycocyanin (C-PC) from blue-green algae has been reported to have various pharmacological characteristics, including anti-inflammatory and anti-cancer activities. In this study, the beta-subunit of C-PC (ref to as C-PC/beta) was expressed and purified from bacteria E. coli BL-21. The recombinant C-PC/beta has been demonstrated to have anticancer properties. Under the treatment of 5 microM of the recombinant C-PC/beta, four different cancer cell lines accrued a high proliferation inhibition and apoptotic induction. The C-PC/beta interacts with membrane-associated beta-tubulin and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) has been found. Under the treatment of the C-PC/beta, depolymerization of microtubulin and actin-filament was observed. The cells underwent …
