Investigation Of Moringa Oleifera Leaf Extract And Its Cancer-Selective Antiproliferative Properties, Reagen H. Welch, Ashlee H. Tietje

Journal of the South Carolina Academy of Science

Moringa oleifera is a tree native to a number of Asian, African, and Central American countries and has been used in traditional medicine for an assortment of medicinal uses for centuries. Due to bioactive compounds within Moringa leaves, it is believed that Moringa leaf extract may possess cancer-selective antiproliferative properties. Previous research has been conducted in regards to this topic, but poor experimental design due to lack of necessary controls limits the legitimacy of anticancer claims. While previous research has shown that Moringa leaf extract has the potential to kill cancer cells, the research fails to demonstrate the effects of …

The Chemotherapeutic Potential Of Resveratrol-Based Treatments, Connor Peck, Kim O'Neill

Journal of Undergraduate Research

Cancer is one of the most prevalent and deadly diseases in the world. In 2012 alone, there were approximately 14 million new cases of cancer and over 8 million cancer-related deaths worldwide. Despite extensive research in past decades, the burden of cancer continues to increase.

One of the most common treatments for cancer is chemotherapy, the use of various chemical substances that exhibit anti-cancer activity. Unfortunately, chemotherapy can be quite toxic and often produces inadequate results. There remains a great need for improved chemotherapeutic treatment strategies in order to improve outcomes for cancer patients.

The purpose of my project was …

Cellular Mechanism Of Thymidine Kinase 1 Secretion, Wei Meng, Kim O'Neill

Journal of Undergraduate Research

Cancer remains the second most common cause of death in the US, accounting for nearly 1 of every 4 deaths. Studies have shown that the early detection of cancer leads to better patient prognosis and a greater five-year survival rate. [1] Diagnostic and prognostic markers play a key role in classifying tumors and determining the best treatment plan for a patient. Among these biomarkers, Thymidine kinase 1 (TK1) has been studied extensively, primarily as a diagnostic biomarker for a variety of cancer types. TK1 plays a role in regulating the intracellular thymidine pools throughout the cell cycle, and thus regulates …

Transition From Cardiovascular Disease To Cancer As The Leading Cause Of Death In Us States, 1999-2014, Michael C. Harding, Evan Thacker

Journal of Undergraduate Research

In 1900 the three leading causes of death in the United States were pneumonia and influenza; tuberculosis; and gastritis, enteritis, and colitis.¹ However, through a combination of improved sanitation, the discovery of antibiotics, and the advent of vaccination programs, deaths from infectious diseases subsided and soon gave way to chronic diseases.² Shortly after the turn of the century, diseases of the heart became of the number one cause of death, and in the 1940s, cancer began consistently appearing at number two. Since then, heart disease and cancer have remained firmly entrenched as the number one and two causes …

Splice Site Predictor, Mark Wadsworth, Dr. Perry G. Ridge

Journal of Undergraduate Research

With the advent of nextgeneration sequencing, one of the unintended consequences is the sheer number of genomic variations requiring interpretation. Mutations in splice sites have been shown to contribute to the development of cancer [1], and dementia [2] among other potentially deadly disorders. Roughly 14 million people are diagnosed with cancer every year [3], and roughly 7 million with dementia [4]. Since these diseases cause an incredible amount of suffering, scientists in all fields are driven to search for ways to identify and treat them. These have been particularly difficult to interpret and have been largely ignored by the bioinformatics …

Natural Killer (Nk) Cells And Their Involvement In Different Types Of Cancer. Current Status Of Clinical Research, Isadora Zaharescu, Adina D. Moldovan, Cristiana Tanase

Journal of Mind and Medical Sciences

Natural killer cells are the main agents of innate immunity. Since 1970, various studies have repeatedly confirmed their involvement in decreasing local tumor growth and also decreasing the risk of metastasis, due to their cytotoxic effects and also through the release of immunostimulatory cytokines such as IFN-gamma. In the 1990s, several studies demonstrated the existence of certain inhibiting and stimulating receptors of these cells, leading to the concept of “induced self”, thus explaining why tumors with MHC-1 are destroyed and autologous cells without it are saved out. Recognition and destruction of tumor cells by the NK cells are the result …

Th1 Cells In Cancer-Associated Inflammation, Güneş Di̇nç Akbulut, Di̇dem Özkazanç, Güneş Esendağli

Turkish Journal of Biology

The immune system is not only evolved to protect the body from pathogens, but it also recognizes and eliminates cancer cells. CD4+ helper T (Th) lymphocytes are central intercessors differentiated according to the character of physiological or pathological status. Generation of type 1 Th (Th1) cells is primarily associated with a pathological insult that must be removed through immune elimination. Upon interacting with other immune and transformed cells, Th1 cells can hamper cancer progression. Therefore, it is a major obstacle for tumor cells to become insensitive or resistant to Th1-oriented actions. The organism employs various mechanisms to return to a …
