P66shc--A Longevity Redox Protein In Human Prostate Cancer Progression And Metastasis : P66shc In Cancer Progression And Metastasis., Mythilypriya Rajendran, Paul Thomes, Li Zhang, Suresh Veeramani, Ming-Fong Lin

Journal Articles: Biochemistry & Molecular Biology

p66Shc, a 66 kDa proto-oncogene Src homologous-collagen homologue (Shc) adaptor protein, is classically known in mediating receptor tyrosine kinase signaling and recently identified as a sensor to oxidative stress-induced apoptosis and as a longevity protein in mammals. The expression of p66Shc is decreased in mice and increased in human fibroblasts upon aging and in aging-related diseases, including prostate cancer. p66Shc protein level correlates with the proliferation of several carcinoma cells and can be regulated by steroid hormones. Recent advances point that p66Shc protein plays a role in mediating cross-talk between steroid hormones and redox signals by serving as a common …

Nm23-H1 Blocks Cell Motility Independently Of Its Known Enzymatic Activities In A Cohort Of Human Melanoma Cells, Joseph Robert Mccorkle

University of Kentucky Doctoral Dissertations

The metastasis suppressor gene NM23-H1 has been shown to possess three enzymatic activities including nucleoside diphosphate kinase, histidine-dependent protein kinase and 3’-5’ exonuclease activity. While these properties have been demonstrated in vitro using recombinant proteins, the contribution of these activities to suppression of metastatic dissemination is unknown. Site-directed mutagenesis studies were used to identify amino acid residues which are required for proper function of each enzymatic activity associated with H1, providing a platform for studying the importance of each function on an individual basis. To assess the relevance of these activities to melanoma progression, a panel of mutants harboring selective …

Brms1 Coordinately Regulates Microrna To Suppress Breast, Mick D. Edmonds

All ETDs from UAB

The majority of cancer related mortality is attributed to complications associated with metastatic disease. Breast cancer metastasis suppressor 1 (BRMS1) suppresses metastasis of multiple cancer types in vivo and loss of nuclear BRMS1 is associated with ER-negative cancers and a high rate of proliferation. Many groups have shown BRMS1 to regulate the expression of multiple metastatic genes, yet until now no one has been able to account for how these many changes in gene expression occur. In this work, we report that BRMS1 regulates a select set of genes called microRNA (miRNA), and these miRNA themselves can regulate metastasis. Using …

Molecular Mechanisms Of Breast Cancer Metastasis: Gap Junction Intercellular Communication And The Bone Microenvironment, Thomas Morgan Bodenstine

All ETDs from UAB

Metastatic disease accounts for the overwhelming majority of cancer related deaths. More specifically, breast cancer remains one of the leading causes of death in women and breast cancer cells metastasize to bone more than any other secondary site. Upon arriving within the bone microenvironment, breast cancer cells interact with bone marrow cells, leading to changes in bone biology that favor growth of the cancer cells. Additionally, some cancer cells are capable of direct cellular communication with cells at metastatic sites via dysregulation of a family of proteins known as connexins. This direct, physical communication is known as gap junctional intercellular …

The Role Of Gli1 In Eralpha-Negative Breast Cancer: Promoting Survival, Migration, Invasion, And Metastasis, Yeon-Jin Kwon

All ETDs from UAB

Glioma-associated oncogene homolog 1 (Gli1) is a well-known oncogene and a transcription factor that mediates several signaling pathways important for tumor progression, such as hedgehog, TGFß, Ras, and EGFR. Although Gli1 is known to play an important role in cancers of brain, skin, prostate, and the pancreas, the role of Gli1 in breast cancer was not previously well-defined. Therefore, this dissertation focuses on defining the role of Gli1 and the mechanism underlying Gli1-mediated transcription in breast cancer. Interestingly, the major findings of the dissertation clearly indicate that Gli1 promotes cell survival and is predictive of a poor outcome in Estrogen …
