Pt-Mal-Lhrh Mediates Breast Cancer Cell Cytotoxicity Through Increased Apoptosis, Kendall E. Collins Nov 2016

Pt-Mal-Lhrh Mediates Breast Cancer Cell Cytotoxicity Through Increased Apoptosis, Kendall E. Collins

Posters-at-the-Capitol

In the United States one in eight women will be afflicted with breast cancer. It is estimated that in 2016 there will be approximately 246,600 new invasive breast cancer cases and 61,000 new non-invasive cases. Triple negative breast cancers account for 15% of all breast cancers and are significantly more aggressive than other subtypes. Treatment options for triple negative breast cancer are limited due to the cancers not expressing the estrogen, progestogen, or herceptin receptors making them unresponsive to hormonal therapy. Our recent work centers around developing a novel chemotherapeutic agent that will direct therapy selectively to triple ...

Semaphorin3a Increases Focal Adhesion Formation To Shift The Relationship Between Cell Migration And Substratum Concentration Through A Rock-Dependent Mechanism, Frances V. Compere, Scott Gehler Jun 2016

Semaphorin3a Increases Focal Adhesion Formation To Shift The Relationship Between Cell Migration And Substratum Concentration Through A Rock-Dependent Mechanism, Frances V. Compere, Scott Gehler

Celebration of Learning

Cell migration is essential for many life processes, including wound healing, embryonic development and cancer metastasis. Cells move across a surface by interacting and forming adhesions with the molecules in their environment, specifically the extracellular matrix. Past studies have shown that there is an optimal level of cell-substratum adhesive strength that allows for the most cell migration and spreading (DiMilla et al., 1993; Gaudet et al., 2003). The mechanism by which this works is not well understood, however. Semaphorin 3A (Sema3A) has been shown to increase the expression of integrin receptors, which help mediate the formation of the adhesions between ...

Neutrophils and macrophages differentiate from common myeloid progenitors in the bone marrow, where they undergo unique nuclear morphologic changes as they mature into fully functional phagocytes. These changes include condensation of chromatin, the most pronounced exhibited by mature neutrophils. Both myeloid cells acquire multiple functions critical to their ability to kill pathogens, including phagocytosis, the production of proteolytic enzymes and reactive oxygen species (ROS), and in the case of neutrophils, release of nuclear material known as nuclear extracellular traps (NETs). Studies on these functions often rely on the use of cells acquired from mature mouse tissues, but these tend to ...

Down syndrome is the leading genetic cause of intellectual disabilities, occurring in 1 out of 700 live births. Given that Down syndrome is caused by an extra copy of chromosome 21 that involves over-expression of 400 genes across a whole chromosome, it precludes any possibility of a genetic therapy. Our lab has long studied the natural dosage compensation mechanism for X chromosome inactivation. To “dosage compensate” X-linked genes between females and males, the X-linked XIST gene produces a large non-coding RNA that silences one of the two X chromosomes in female cells. The initial motivation of this study was to ...


Microengineering Approaches For Regenerative Medicine, Yubing Sun May 2016

Microengineering Approaches For Regenerative Medicine, Yubing Sun

UMass Center for Clinical and Translational Science Research Retreat

Stem cells, especially human pluripotent stem cells (hPSCs), hold significant promise for modeling developmental and disease processes, drug and toxicology screening, and cell-based regenerative medicine. Most hPSC studies have so far focused on identifying extrinsic soluble factors, intracellular signaling pathways, and transcriptional regulatory networks involved in regulating hPSC behaviors. We focus on the development and applications of some novel synthetic micromechanical systems to understand the mechano-sensitive and -responsive properties of hPSCs and their functional regulation of self-renewal, directed differentiation, and survival of hPSCs. First, we have demonstrated that rigid PDMS micropost arrays (PMAs) support the maintenance of pluripotency of hPSCs ...


Peptide Inhibitors That Disrupt Viral-Viral Protein Interactions In Hiv-1: Literature-Based Review, Kevin Fei Xia Mar 2016

Peptide Inhibitors That Disrupt Viral-Viral Protein Interactions In Hiv-1: Literature-Based Review, Kevin Fei Xia

Undergraduate Research Symposium

Protein-protein interactions play a key role during each stage of the viral life cycle. Thus, inhibiting viral protein-protein interactions with the peptides derived from the binding interfaces is a promising approach for potential multi-epitope based treatments. However, molecular mechanisms underlying these protein interactions are not yet fully understood. This study is focused on a comprehensive literature survey to identify known peptide inhibitors derived from the HIV-1 viral proteins, which disrupt viral-viral protein interactions. We also discuss the limitations of these studies in identifying the most promising candidates. The candidate domains/regions identified in this survey will be used in the ...
