Function Of Long Noncoding Rnas In Breast Cancer, Edward J. Richards Sep 2015

Function Of Long Noncoding Rnas In Breast Cancer, Edward J. Richards

USF Tampa Graduate Theses and Dissertations

Breast cancer is a disease that will be diagnosed in about 1 in 10 women throughout their lifetime. The majority of breast cancers are originated from the epithelial cells of the mammary ducts, and this occurrence can be due to several factors including hereditary and acquired mutation. There are several major breast cancer subtypes, including estrogen receptor-α (ERα)-positive, HER2-enriched and triple-negative (TNBC). Patients diagnosed with ER+ tumors are generally treated with estrogen blockers (e.g., tamoxifen, letrozole and fulvestrant). Patients with HER2+ tumors are commonly administered with drugs that block HER2 signaling (e.g., trastuzumab) or inhibit HER2’s tyrosine kinase activity (e.g., …


The Role Of Srsf3 In Control Of Alternative Splicing Of Cpeb2 In Triple Negative Breast Cancer, Brian P. Griffin Jan 2015

The Role Of Srsf3 In Control Of Alternative Splicing Of Cpeb2 In Triple Negative Breast Cancer, Brian P. Griffin

Theses and Dissertations

In the presented study, we identified that SRSF3 controls the alternative splicing of CPEB2 and consequently promotes a metastatic phenotype in triple negative breast cancer (TNBC). TNBC causes thousands of deaths annually, frequently due to a lack of effective treatments and a high rate of metastasis in patients. Alternative splicing has been found to be dysregulated in numerous cancers, while splicing factors such as SRSF3 are variably expressed. In this study we performed a siRNA panel to screen potential splicing factors, then used specific siRNA to study the effect of its knockdown on cellular function. These results showed that SRSF3 …
