The Role Of Long Non-Coding Rna (Lncrna) In The Organization Of Nuclear Bodies, Soobin An

Symposium of Student Scholars

Nuclear bodies (NBs) (e.g., the nucleolus, nuclear speckles, and others) are membraneless compartments within the eukaryotic cell nucleus that selectively accumulate and retain specific nuclear proteins. NBs have become a new interest in recent discoveries because of their potential involvement in cancer and neurological disorders. However, the regulation and function of NBs are still enigmatic. Our laboratory studies a specific type of NBs, called B-bodies, to understand how NBs are formed and regulated in the nucleus. We hypothesized that long non-coding RNA (lncRNA) functions as a structural scaffold of NBs.

The B-body is a recently discovered NB expressed in the …

Utilizing Rnai Technology To Develop Novel Agricultural Pesticides, Ethan B. Zand

Undergraduate Student Research Internships Conference

A general description of why RNAi based pesticide technology is a breakthrough technology able to target only pests while not harming others. This presentation gives a summary of RNAi technology, the current drawbacks of conventional pesticides, and our research on how RNAi can be used against the two-spotted spidermite; a polyphagic pest that causes significant financial damage to Canadian and worldwide agriculture

Spr-5; Met-2 Maternal Reprogramming Cooperates With The Dream Complex To Regulate Developmental Cell Fates, Jazmin Dozier, Sandra Nguyen, Brandon Carpenter

Symposium of Student Scholars

Histone methylation is a post-transcriptional modification to the N-terminal tails of histone core proteins that regulates DNA accessibility, and consequently, gene expression. Like DNA, histone methylation can be inherited between generations, and is highly regulated during embryonic development. At fertilization, histone methylation must undergo maternal reprogramming to reset the epigenetic landscape in the new zygote. During maternal reprogramming of histone methylation in the nematode, C. elegans, H3K4me (a modification associated with active transcription) is removed by the H3K4 demethylase, SPR-5, and H3K9me (a modification associated with transcriptional repression) is subsequently added by the histone methyltransferase, MET-2. Recently, it was …

Tissue-Specific Diversity Of The Muscleblind Expression In Adult Flies., Davron Hanley, Anton Bryantsev

Symposium of Student Scholars

Department of Molecular and Cellular Biology, Kennesaw State University

The muscleblind (mbl) family of RNA-binding proteins regulates alternative splicing, determining mRNA transcript composition for various types of tissue, and has been implicated in myotonic dystrophy. The mbl gene is subject to alternative splicing in Drosophila, leading to multiple isoforms, and has several paralogs in humans. Mbl proteins vary significantly in length, although the significance of such diversity and the role of specific isoforms have not been fully explored.

Using immunofluorescence microscopy and polyclonal serum, we analyzed Mbl protein expression across adult Drosophila tissues. Mbl was detected in …
