Exposure To Endocrine Disrupting Chemicals And The Effects On Inflammation And Mammary Tumor Progression, Stephanie Morin
Exposure To Endocrine Disrupting Chemicals And The Effects On Inflammation And Mammary Tumor Progression, Stephanie Morin

The vast majority of breast cancers, ~70%, are not directly related to an inherited genetic mutation. Environmental factors play a dominant role in the etiology of most breast cancers. There is a subset of chemicals that are able to affect the homeostasis of hormones called endocrine disrupting chemicals (EDCs). Many of these chemicals are pervasive and persistent making the chances for lifetime exposure more prevalent. While many of these chemicals have been deemed safe, a subset of them have come under review to reassess their safety. As estrogen is critical for breast development and can act as a mitogen in …
Environmental Risk Factors For Inflammatory Bowel Disease: Triclosan And Other Consumer Antimicrobials, Katherine Z. Sanidad
Environmental Risk Factors For Inflammatory Bowel Disease: Triclosan And Other Consumer Antimicrobials, Katherine Z. Sanidad
Doctoral Dissertations
Inflammatory bowel disease (IBD) has become a serious health problem since the incidence and prevalence of IBD has dramatically increased throughout the world. There is evidence that environmental factors are primarily responsible for the increase of IBD, therefore, it is important to identify novel environmental risk factors to reduce the risk of IBD and its associated diseases. Antimicrobials used in consumer products might serve as environmental risk factors for IBD and its associated diseases. Triclosan (TCS), triclocarban (TCC), benzalkonium chloride (BAC), benzethonium chloride (BET), and chloroxylenol (PCMX) are widely used antimicrobial ingredients in consumer products and are ubiquitous contaminants in …

Notch1 is a rational therapeutic target in several human cancers, but as a transcriptional regulator, it poses a drug discovery challenge. To identify Notch1 modulators, we performed two cell-based, high-throughput screens for small-molecule inhibitors and cDNA enhancers of a NOTCH1 allele bearing a leukemia-associated mutation. Sarco/endoplasmic reticulum calcium ATPase (SERCA) channels emerged at the intersection of these complementary screens. SERCA inhibition preferentially impairs the maturation and activity of mutated Notch1 receptors and induces a G0/G1 arrest in NOTCH1-mutated human leukemia cells. A small-molecule SERCA inhibitor has on-target activity in two mouse models of human leukemia and interferes with Notch signaling …
