Abstract 4969: Metformin causes AR degradation via Skp2-mediated ubiquitination
This study supports that use of metformin in combination with Enza or other ARSI drugs may not only block autophagy survival but also cause AR degradation that leads to PC cell death.Citation Format: Joy C.

Abstract P5-04-13: Toll like receptor-9 and CD73 may act on the same pathway to induce immunosuppression in triple negative breast cancer cells
Toll like-receptor-9 (TLR9) is an innate immune system DNA-receptor which is also widely expressed in breast cancer cell lines and in clinical breast cancer specimens. Although TLR9 ligands (such as bacterial DNA and synthetic, CpG-sequence containing oligonucleotides) induce TLR9-mediated invasion in breast cancer cells in vitro, the contribution of this protein to breast cancer pathophysiology remains unclear. We showed previously that tumor TLR9 expression is a highly significant prognostic factor in breast cancer, but only in tumors that are triple negative (TNBC). Specifically, low tumor TLR9 expression in TNBC is ass...

Abstract 30: Modulating the angiogenic potential of human microvascular endothelial cells by an endogenous zinc finger transcription factor, ZNF24
Angiogenesis, the formation of new blood vessels from preexisting ones, is an indispensible process under normal physiological conditions such as embryonic development, certain stages of the female reproductive cycle and placenta formation during pregnancy as well as under pathological conditions such as wound healing, diabetic retinopathy, and cancer initiation, progression and metastasis. We have previously identified the molecular mechanism by which a zinc finger transcription factor, ZNF24, functions as a new inhibitor of tumor angiogenesis. ZNF24 represses the transcription of vascular endothelial growth factor (VEGF)...

Abstract 2270: TRAIL-TZD combinatorial treatment induces apoptosis in prostate cancer cells through modulation of AMPK signaling pathway
In this study we determined AMP-activated protein kinase (AMPK) as a potential target for TRAIL-TZD-induced apoptosis in prostate cancer cells. AMPK is a family of serine/threonine protein kinase and is highly conserved from yeast to human. It consists of three subunits: a catalytic α subunit and regulatory β and γ subunits. AMPK is a well-accepted target for the treatment of metabolic syndrome and Type 2 diabetes. We used C42-DN (stably overexpressing AMPK α1-dominant negative) and C42-EV (empty vector) prostate cancer cell lines to study differences in TRAIL-TZD-induced apoptosis. Our studies showed a dose dependent ...
