A Randomized Controlled Study Of Heart Rate Variability Biofeedback In An Older Adult Sample, Whitney D. Allen

Theses and Dissertations

Heart rate variability biofeedback (HRVB) is a controlled breathing treatment designed to increase the variation in consecutive heartbeats leading to improved regulation of one's autonomic nervous system thereby improving one's ability to self-regulate and maintain homeostasis. Changes in heart rate variability (HRV) are seen in those of increased age and lower HRV is associated with poorer outcomes (e.g., increased mortality, worse emotional functioning, cardiovascular risk factors). As such, older adults are a group that stands to benefit from HRVB principles. The current randomized control trial was designed to understand the impact of HRVB in an older adult population on resting …

The mutational landscape of phylogenetically ultraconserved elements (UCEs), especially those in noncoding DNAs (ncUCEs), and their functional relevance in cancers remain poorly characterized. Here, we perform a systematic analysis of whole-genome and in-house targeted UCE sequencing datasets from more than 3000 patients with cancer of 13,736 UCEs and demonstrate that ncUCE somatic alterations are common. Using a multiplexed CRISPR knockout screen in colorectal cancer cells, we show that the loss of several altered ncUCEs significantly affects cell proliferation. In-depth functional studies in vitro and in vivo further reveal that specific ncUCEs can be enhancers of tumor suppressors (such as ARID1B) …

Nuclease-deactivated Cas (dCas) proteins can be used to recruit epigenetic effectors, and this class of epigenetic editing technologies has revolutionized the ability to synthetically control the mammalian epigenome and transcriptome. DNA methylation is one of the most important and well-characterized epigenetic modifications in mammals, and while many different forms of dCas-based DNA methyltransferases (dCas-DNMTs) have been developed for programmable DNA methylation, these tools are frequently poorly tolerated and/or lowly expressed in mammalian cell types. Further, the use of dCas-DNMTs has largely been restricted to cell lines, which limits mechanistic insights in karyotypically normal contexts and hampers translational utility in the …
