Cloning and characterization of exc-9, a Caenorhabditis elegans CRIP homologue that regulates tubular structure
… is fundamental to organismal development. The excretory canal cell of C.elegans forms a single-cell epithelial tubule, which provides a simple model for tubular structure study. The EXC proteins regulate maintenance of the apical (lumenal) cytoskeleton of the excretory canal. Loss of exc gene …

EXC-5 Controls Intracellular Trafficking in Order to Maintain the Apical Structure of the C. elegans Excretory Canal
… form and maintain tubular shapes. The protein EXC-5 is necessary for a small tubular structure in Caenorhabditis elegans to maintain its shape. C. elegans is a small, easily manipulable, genetically tractable, and transparent nematode with a unicellular excretory canal system. The C. elegans …

DNA -Protein Interactions in the CTnDOT Excisive Intasome
The excision mechanism of CTnDOT is more complicated than any system studied to date. Excision requires multiple accessory proteins. Exc is one protein required for excision, however, its function is unknown. In an attempt to determine a role for Exc, the native wild type Exc protein was purified. …

Excision of the Bacteroides Conjugative Transposon CTnDOT
In this study, we showed that expression of the exc operon is regulated by tetracycline and mediated by the regulatory proteins, RteA, RteB, and RteC. Tetracycline induces the expression of rteA and rteB, genes in the tetQ operon. Then, RteB induces the expression of rteC. RteC, subsequently, …

Positive regulators of Bacteroides CTnDOT excision and transfer
Tetracycline stimulates both excision and transfer of a Bacteroides Conjugative transposon CTnDOT. It was shown previously that a gene, rteC, is necessary for tetracycline-stimulated transcriptional regulation of the xis2c operon, which contains the excision genes. The protein encoded by this gene, …

Skeletal muscle mass, function, and metabolic regulation between menopause stages in moderately active mid-life females
… low impact resistance exercise training program (EXC) or maintained habitual physical activity (CON). EXC significantly increased hip strength (19-20%), dynamic balance (>10%), flexibility (21%) and lean mass (2%). These adaptations were comparable between pre-, peri- and post-menopause groups, …

Excision, transfer, and integration of the bacteroides integrative and conjugative element CTnDOT
… through a complex regulatory cascade. The excision operon is a key component of this regulation, and is involved at many different levels of the regulatory cascade. As the name implies, the expression of the excision operon promotes the excision of CTnDOT from the host chromosome. Once the …

Transcriptional regulation of mobilization and transfer of the Bacteroides conjugative transposon CTnDOT
… A notable feature of CTnDOT is that excision from the donor chromosome and conjugative transfer are coordinately regulated upon exposure of donor cells to tetracycline (Tc). While no transfer is detected in the absence of Tc, upon Tc induction a regulatory cascade ultimately …

Regulatory Genes of the Bacteroides Conjugative Transposon, CTnDOT
… order to examine which genes are responsible for excision, I first demonstrated that the excision genes orf2c, orf2d, orf3, and exc are part of an operon (the orf2c operon) and that this operon is regulated at the transcriptional level. I found that RteC is an DNA-binding activator of the orf2c …

A Genome-Scale Analysis of Alternative Splicing Regulation by Splicing Factors in C. elegans
… this thesis, I focus on four SFs – ASD-1, FOX-1, EXC-7 and MEC-8. In the first data chapter, I use RNA sequencing, RNA-binding preferences and conservation information to identify likely direct targets of these SFs. I find that AS regulation by these SFs is often combinatorial and converges upon …

Volatile chemistry, and nitrogen sources and fluxes, in subduction zones : insights from the Izu-Bonin-Mariana Arc
… Most samples have high N2/He and low CO2/N2,exc., due to addition of sedimentary nitrogen from the subducting slab. This is confirmed by δ15N values, which are generally positive – up to +5.5°. Quantitative mixing calculations indicate that, after correction for atmospheric contamination, an …
