Mitochondria-To-Nucleus Retrograde Signaling And Its Role In Cancer, Trevor Carden Jan 2018

Mitochondria-To-Nucleus Retrograde Signaling And Its Role In Cancer, Trevor Carden

All ETDs from UAB

Mitochondrial dysfunction is considered a hallmark of cancer. Mitochondria are essential, cellular organelles that participate in processes including energy production, calcium homeostasis and steroid metabolism. Mitochondria have been more recently appreciated for their role in cellular signaling, bringing about a greater understanding of their role in many diseases including cancer. Retrograde signaling is a mechanism by which the nucleus responds to mitochondrial dysfunction by modulating its own transcriptional programs to maintain metabolic and cellular processes. Many genes have already been identified as participants in or mediators of this signaling mechanism; these include cell signaling, metabolic and structural genes as well …


Elucidating The Role Of Hedgehog Signaling In Modulating Macrophage Function In Breast Cancer, Ann Hanna Jan 2018

Elucidating The Role Of Hedgehog Signaling In Modulating Macrophage Function In Breast Cancer, Ann Hanna

In the tumor microenvironment, breast cancer cells participate in crosstalk with the surrounding stroma. This tumoral-stromal interaction forms a balance that dictates tumor suppressing or tumor promoting response mechanisms. Macrophages in the tumor microenvironment are plastic and can mediate several functions depending on their activation states. Tumor associated macrophages co-exist as two major phenotypes: anti-tumorigenic and immune-eliciting classically activated M1 as well as tumor-promoting and immune-suppressive alternatively activated M2 macrophages. Alternatively activated macrophages are specifically associated with more aggressive stages and poor clinical outcomes in breast cancer patients as they suppress the tumoricidal properties of the immune system, thus facilitating …


Cardiovascular Disease Risk Among Breast Cancer Survivors, Jacqueline B. Vo Jan 2018

Cardiovascular Disease Risk Among Breast Cancer Survivors, Jacqueline B. Vo

All ETDs from UAB

Background: There are nearly 3.5 million breast cancer survivors in the U.S., and approximately 10% are diagnosed prior to age 45 and considered “young.” The overall five-year survival rate for breast cancer survivors is approaching 90%. Living longer, many breast cancer survivors are at risk for developing cardiovascular disease due to cancer treatment, such as anthracyclines and/or trastuzumab. This study’s purpose was to examine cardiovascular disease risk, measured using excess heart age, among young breast cancer survivors. Methods: A retrospective, two-year longitudinal design was used to review electronic medical records of breast cancer survivors diagnosed between 30 and 44 years …
