A path towards better cancer drugs: Modeling interactions between antimitotic agents and tubulin
DownloadFall 2015
Antimitotic agents, a class of cancer chemotherapies, target the tubulin protein in microtubules to suppress microtubule dynamics and affect the segregation of chromosomes during cell division. A variety of antimitotic agents are known, which range in status from clinically-approved agents to...

An investigation of factors that regulate cytoskeleton in the first mitotic division of the C. elegans embryo
DownloadFall 2017
Microtubule dynamics is regulated by naturally occurring microtubule-associated proteins occurring in the cellular environment as well as by natural and synthetic compounds. These compounds target the microtubule cytoskeleton and serve as anti-mitotic drugs. Therefore, microtubules continue to be...

Microtubules are cellular structures that are crucial to many cellular functions including maintenance of cell shape, vesicular transport, and cell division. The dynamic instability of microtubules is the basic feature which enables them to do their cellular functions. Their pivotal role in cell...

Drosophila ATM and ATR have distinct activities in the regulation of meiotic DNA damage and repair

Tiong, S., McKim, K.S., Campbell, S.D., White-Brown, S.K., Paul, A., Pedersen, M., Joyce, E.F.
Ataxia telangiectasia–mutated (ATM) and ataxia telangiectasia–related (ATR) kinases are conserved regulators of cellular responses to double strand breaks (DSBs). During meiosis, however, the functions of these kinases in DSB repair and the deoxyribonucleic acid (DNA) damage checkpoint are...

In the newly fertilized embryo, meiotic and mitotic spindles form consecutively within the same egg cytoplasm. The order of events during this transition is controlled, in part, via the regulation of the microtubule cytoskeleton. Herein, I show that mel-43 is part of a small paralogous gene...

Spindle assembly pathways are conserved in many organisms. Defects in spindle assembly can result in aneuploidy, a common cause of cell death and cancer. A better understanding of spindle assembly pathways is required to fully appreciate how defects in spindle assembly manifest as aneuploidy and...

Meiosis in eukaryotes includes a developmentally programmed pre-meiotic G2 phase arrest before the onset of MI division mediated by inhibitory phosphorylation of Cdk1. There are two inhibitory kinases, Wee1 and Myt1. Myt1 mediated Cyclin B-Cdk1 regulation serves as a conserved mechanism for...

Mapping and characterization of mel-43(sb41), a gene required for early embryonic viability in C. elegans
DownloadSpring 2010
A genetic screen for dominant, temperature-sensitive, maternal-effect embryonic lethal mutations identified mel-43(sb41), a gene required for early embryonic viability (Mitenko et al., 1997). Linkage mapping placed mel-43 within a small region on chromosome IV. Genetic analyses suggested that...

Three important mechanical behaviors of microtubules in vivo, i.e., buckling, vibration and splitting are investigated with especial focus on their relevance to biological functions of microtubules. To study the vibration and buckling of a microtubule, we model a microtubule as an elastic beam...

The thesis is divided in three parts based largely on published articles or on manuscripts submitted for publication. First we propose a new method which is called the shooting-bead method. This method is a fast and easy experimental technique for evaluating cantilever stiffness and flexural...
