The Role Of Atypical Protein Kinase C In Colorectal Cancer Cells Carcinogenesis, S M Anisul Islam Nov 2019

The Role Of Atypical Protein Kinase C In Colorectal Cancer Cells Carcinogenesis, S M Anisul Islam

USF Tampa Graduate Theses and Dissertations

Colorectal cancer (CRC) is the third most common malignancy and the fourth most common cause of cancer-related death worldwide. CRC is a life-threatening disease due to therapy-resistant cancerous cells. The exact mechanisms of cell growth, survival, metastasis and inter & intracellular signaling pathways involved in CRC are still a significant challenge. Moreover, the treatment of metastatic CRC considered palliative for many years aimed for an improved life, with little hope of a cure, highlighting the need for developing novel targeted therapy for CRC. Hence, investigating new molecular mechanism(s) that lead to colorectal carcinogenesis may give insight into the therapeutic target. …


Hybrid Fusion Protein For Inhibition Of Multiple Proteases For Chronic Wound Healing, Graham L. Strauss Jul 2019

Hybrid Fusion Protein For Inhibition Of Multiple Proteases For Chronic Wound Healing, Graham L. Strauss

USF Tampa Graduate Theses and Dissertations

Many diseases display a multitude of relevant factors that contribute to the persistence of the disease and difficulty treating it. The multifactorial characteristics of some diseases lead to the requirement of combination of treatments in order to restore health. The latter may necessitate the mixing of treatments, medications, and therapeutics to first halt the disease, then assist the human body in returning itself to a state of normality. For example, chronic wounds exhibit this multifactor characteristic in which there exist many factors that lead to the body’s inability to properly heal in a timely manner. This presents a further threat …


Targeting Pten For Therapy In Cancer And Ptenopathies, Emily Palumbo Jul 2019

Targeting Pten For Therapy In Cancer And Ptenopathies, Emily Palumbo

USF Tampa Graduate Theses and Dissertations

PTEN, a dual protein and lipid phosphatase, regulates a myriad of cellular functions including PI3K pathway signaling, cell migration, proliferation, invasion and apoptosis. PTEN mutations often lead to multiple malignancies, including prostate, breast, endometrial, skin and brain cancers, associated with hyperactive PI3K signaling. PTEN mutations have also been associated with a variety of other diseases, classified as PTEN Hamartoma Tumor Syndromes (PHTS). In addition, compromised function or reduced expression of PTEN due to non-genomic mechanisms are associated with many types of hyperproliferative diseases, such as restenosis and neoplastic diseases, including melanoma, lung, breast, prostate and colon cancers. Although PI3K pathway …


Roux-En-Y Gastric Bypass Attenuates Obesity-Related Liver Injury, Drew Alan Rideout Jul 2019

Roux-En-Y Gastric Bypass Attenuates Obesity-Related Liver Injury, Drew Alan Rideout

USF Tampa Graduate Theses and Dissertations

Obesity is a growing epidemic in the United States with significant co-morbidities. Non-Alcoholic Fatty Liver Disease (NAFLD) is a prevalent manifestation of obesity that can lead to cirrhosis. Roux-en-Y gastric bypass (RYGB) results in substantial long-term weight loss and resolution of obesity-related metabolic diseases. There appears to be a weight-independent molecular mechanism for the improvement of diabetes mellitus and NAFLD after RYGB, which is poorly understood. Obesity is associated with chronic inflammation that accompanies the hepatic steatosis. Through unknown mechanisms, RYGB in humans increases serum levels of the fat-derived adipocytokine, adiponectin. Adiponectin (an anti-inflammatory cytokine) is known to have a …
