The Role Of Lipocalin 2 In Early Stage Colon Cancer Metastasis To The Liver, Fides Elamparo
The Role Of Lipocalin 2 In Early Stage Colon Cancer Metastasis To The Liver, Fides Elamparo
Senior Theses
Metastasis, frequently from the colon to the liver, is the major cause of death with colorectal cancer, reducing the five-year survival to less than 6%. Metastasis occurs due to productive collaborations between tumor cells and host-derived cells in the tumor microenvironment, where a pre-metastatic niche is created to prime for cancer cell invasion into the target organ. In a highly metastatic colorectal cancer cell line implanted into the cecum of Balb/c mice, microarray analysis showed lipocalin 2 (Lcn2) is one of the most highly expressed proteins in the liver of tumor-bearing mice prior to metastasis.
When RT-PCR was performed, greater …
Rna Interference Targeting Glucose-Regulated-Protein 78 Induces Hepg2 Cell Apoptosis, Brittany Blackman
Rna Interference Targeting Glucose-Regulated-Protein 78 Induces Hepg2 Cell Apoptosis, Brittany Blackman
Seton Hall University Dissertations and Theses (ETDs)
Cancer is a complex genetic disease that is driven by genetic mutations resulting in chronic, inappropriate cell proliferation. Many current cancer therapies lack specificity towards tumor tissues, ultimately leading to adverse side effects and limited clinical efficacy. Recently, selective cancer cell therapy has examined a well-characterized cell surface marker that is preferentially expressed on tumor cells. The over-expression of an endoplasmic reticulum chaperone protein, 78-kDa glucose-regulated-protein (GRP78), has been observed on the surface of cancer cells, but not on normal tissues. By selectively targeting GRP78 with short-interfering RNA (siRNA), potent GRP78 silencing is anticipated by the RNA interference (RNAi) pathway. …

A Study On The Function Of 14-3-3sigma In Regulating Cancer Energy Metabolism, Liem M. Phan, Liem M. Phan

Metabolic reprogramming has been shown to be a major cancer hallmark providing tumor cells with significant advantages for survival, proliferation, growth, metastasis and resistance against anti-cancer therapies. Glycolysis, glutaminolysis and mitochondrial biogenesis are among the most essential cancer metabolic alterations because these pathways provide cancer cells with not only energy but also crucial metabolites to support large-scale biosynthesis, rapid proliferation and tumorigenesis. In this study, we find that 14-3-3σ suppresses all these three metabolic processes by promoting the degradation of their main driver, c-Myc. In fact, 14-3-3s significantly enhances c-Myc poly-ubiquitination and subsequent degradation, reduces c-Myc transcriptional activity, and down-regulates …
Platelets And Anti-Angiogenic Resistance In Ovarian Carcinoma, Justin N. Bottsford-Miller
Platelets And Anti-Angiogenic Resistance In Ovarian Carcinoma, Justin N. Bottsford-Miller
Dissertations & Theses (Open Access)
Background: Resistance to targeted anti-angiogenic therapy is a growing clinical concern given the disappointing clinical impact of anti-angiogenic. Platelets represent a component of the tumor microenvironment that are implicated in metastasis and represent a significant reservoir of angiogenic regulators. Thrombocytosis has been shown to be caused by malignancy and associated with adverse clinical outcomes, however the causal connections between these associations remain to be identified.
Materials and Methods: Following IRB approval, patient data were collected on patients from four U.S. centers and platelet levels through and after therapy were considered as indicators of recurrence of disease. In vitro effects of …

Increased Geranylgeranylated K-Ras Contributes To Antineoplastic Effects Of Farnesyltransferase Inhibitors., Mandy A. Hall

The Ras family of small GTPases (N-, H-, and K-Ras) is a group of important signaling mediators. Ras is frequently activated in some cancers, while others maintain low level activity to achieve optimal cell growth. In cells with endogenously low levels of active Ras, increasing Ras signaling through the ERK and p38 MAPK pathways can cause growth arrest or cell death. Ras requires prenylation – the addition of a 15-carbon (farnesyl) or 20-carbon (geranylgeranyl) group – to keep the protein anchored into membranes for effective signaling. N- and K-Ras can be alternatively geranylgeranylated (GG’d) if farnesylation is inhibited but are …
Matrix Metalloproteinase Genes Are Transcriptionally Regulated By E2f Transcription Factors: A Link Between Cell Cycle Control And Metastatic Progression, Jacqueline Lea Johnson
Matrix Metalloproteinase Genes Are Transcriptionally Regulated By E2f Transcription Factors: A Link Between Cell Cycle Control And Metastatic Progression, Jacqueline Lea Johnson
USF Tampa Graduate Theses and Dissertations
The RbµE2F transcriptional regulatory pathway plays a critical role in the cell cycle. Rb is inactivated through multiple waves of phosphorylation, mediated mainly by cyclin D and cyclin E associated kinases. Once Rb is inactivated, cells can enter Sµphase. Collectively, three Rb family members and ten E2F proteins coordinate every additional stage of the cell cycle, from quiescence to mitosis. However the RbµE2F pathway is frequently altered in cancer. Aside from cell proliferation, the RbµE2F pathway regulates other essential cellular processes including apoptosis, cell differentiation, angiogenesis and DNA damage repair pathways, but its role in invasion and cancer progression is …
Altered Leptin Signaling On Dendritic Cells As A Potential Mechanism For Cancer Immunotherapy, Lorena Y. De Los Santos
Altered Leptin Signaling On Dendritic Cells As A Potential Mechanism For Cancer Immunotherapy, Lorena Y. De Los Santos
Open Access Theses & Dissertations
Leptin is a pleiotropic hormone synthesized primarily by white adipocytes and its receptors are expressed in a variety of tissues and cells such as in the hypothalamus and cells of the immune system. Multiple cell types can produce a considerable amount of leptin such as skeletal muscle, placenta, and osteoblasts to name a few and its synthesis has been shown to be regulated by sex hormones and a broad range of inflammatory mediators. Although leptin has been shown to directly affect immune response, we are interested in how leptin affects dendritic cell function and their ability to induce a proper …

The literature dealing with the larva of Pacific Coast brachyuran crabs is slight. The prominent papers, those of Aikawa (1927, 1928, 1929, 1933, 1937), deal with a variety of genera and offer information useful in determin- ing family relationships. A single paper by Hart (1935) also deal with a number of brachyuran larvae found in the Pacific Ocean. None of these papers, however, identifies to species any member of the genus Cancer, although one member, C. magister (Dana) is of considerable economic importance on the pacific coast of North America. In the fall of 1958 an investigation was under taken …
