Ethical Issues And Standards Of Responsible Research Conduct And Monitoring In An Adventist Institution Of Higher Learning - The Babcock Experience, Kayode O. Ogunwenmo, Godswill N. Anyasor, Grace O. Tayo

Adventist Human-Subject Researchers Association

Ethical issues and standards of responsible research conduct involving human participants are important considerations in any institution of higher learning and in particular Adventist institutions. Research conduct and ethics are reviewed and approved before they begin by the Babcock University Health Research Ethics Committee (BUHREC)

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 …

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 …

Times Of Action And Evolutionary Conservation Of Heterochronic Genes, Maria Ivanova, Eric G. Moss

Rowan-Virtua Research Day

Specific genes called heterochronic genes control the timing and sequence of developmental events during larval stages of C. elegans. Mutations in heterochronic genes can cause skipping or reiteration of cell fates associated with certain larval stages. lin-14 and lin-28 are two well-studied heterochronic genes. LIN-14 acts during the first larval stage (L1) and controls events of the L1 and L2 stages, LIN-28 acts during the L2 stage and controls its events.

A Screen For Genetic Modifiers Of Protein Phosphatase 1 Function In Drosophila Collective Cell Cohesion And Migration, Carmen F. Del Real, Yujun Chen, Marissa Komp, Jocelyn A. Mcdonald

Kansas State University Undergraduate Research Conference

Cells can migrate collectively in tightly or loosely-associated groups during tissue and organ formation, during embryonic development, in tumor metastases, and in wound healing. Drosophilaborder cellsserve as an excellent genetic model of collective cell migration inside a developing tissue. During ovarian development, 6-8 cells form the border cell cluster and migrate together as a cohesive group to reach the large oocyte. Previous experiments have shown that Nuclear inhibitor of Protein Serine Threonine Phosphatase 1 (NiPP1) causes border cells to separate into single cells, rather than stay in a group, and limits their ability to migrate. NiPP1 inhibits the …
