Theses, Dissertations and Capstones
Dietary components modulate normal cellular functions and, in cancer cells, alter processes that lead to cancer and/or its progression. The change in the patterns of human food production and consumption over time has contributed to increasing risk for diseases including cancer. Omega-3 and omega-6 fatty acids are classes of essential polyunsaturated fatty acids in the human diet and are required for normal growth and development. Omega-3 and omega-6 fats are thought to be required in the ratio of 1:1 to 1:4 on which humans are thought to have evolved. However, the Western diet has greatly shifted from this ratio. The …
Pitx2 Is Overexpressed In Follicular Cell-Derived Thyroid Cancer And Promotes Thyroid Cancer Proliferation By Regulating Cell Cycle, Yue Huang
Theses, Dissertations and Capstones
Thyroid cancer is the most prevailing malignancy of the endocrine system. Its incidence is rapidly rising at the second fastest rate of all malignancies in the United States, making it a significant health problem. Although the majority of thyroid cancer is slowly-growing and well-differentiated, available treatment options are very limited, and most of them require complete removal of the thyroid gland and surrounding tissues. Patients who have undergone thyroid removal have to take life-long hormone replacement therapy, which is very inconvenient and costly. Therefore, there is an urgent need to develop new treatments for this disease. As a prerequisite for …
Cancer Cachexia And Cardiac Atrophy In The Apcmin/+ Mice Model Of Colon Cancer, Nandini Durga Prasanna Kumar Manne
Cancer Cachexia And Cardiac Atrophy In The Apcmin/+ Mice Model Of Colon Cancer, Nandini Durga Prasanna Kumar Manne
Theses, Dissertations and Capstones
Cancer cachexia is a muscle wasting condition that occurs in response to a malignant growth in the body. Cachexia is associated with heart failure and is estimated to be the immediate cause of death in about a third of all cancer patients. The purpose of this study was to investigate cardiac atrophy in the APCmin/+ mouse model of colorectal cancer. Compared to age matched C57BL/6 (BL6) mice, APCmin/+ body mass and heart mass were lower at 12 (11.1 Ѡ4.5% and 7.6 Ѡ2.8%, respectively) and 20-weeks (26.1 Ѡ2.5% and 6.0 Ѡ3.8%, respectively) of age (P < 0.05). Immunoblot analysis revealed that these changes in mass were accompanied by increased activation of protein kinase B (Akt Thr 473: 74.4 Ѡ10.9% and 216.0 Ѡ19.6% ; Akt Ser 308: 161.6 Ѡ31.7% and 367.4 Ѡ41.6% at 12- and 20-weeks, respectively, (P < 0.05)), mammalian target of rapamycin (mTOR Ser2448: 23.2 Ѡ13.2% and 44.0 Ѡ16.4% at 12- and 20-weeks, respectively, (P < 0.05)), 5' adenosine monophosphate-activated protein kinase (AMPK: 19.6 Ѡ5.2% and 22.5 Ѡ5.5% at 12- and 20-weeks, respectively, (P < 0.05)) and elevated levels of the autophagy regulator beclin1 (4.7 Ѡ3.3% and 9.5 Ѡ3.0% at 12- and 20-weeks, respectively, (P < 0.05)). No evidence of increased cardiac apoptosis, protein ubiquitination or activation of cardiac caspases or calpains was noted. Taken together, these data suggest that the cardiac atrophy that occurs in the 12- and 20-week old APCmin/+ mouse is relatively modest compared to that seen with other tumor models [1] and is associated with evidence of increased cardiac autophagy.
