Examining A Functional Interaction Between Chromatin Remodeler Chd1 And Histone H1 In D. Melanogaster, Breanna Kim Jan 2021

Examining A Functional Interaction Between Chromatin Remodeler Chd1 And Histone H1 In D. Melanogaster, Breanna Kim

Scripps Senior Theses

Chromodomain-helicase-DNA-binding-protein-1 (CHD1) is a highly conserved ATP- dependent remodeling protein. It is localized to active genes and directs nucleosome spacing, while its loss has been linked to various human diseases, such as human prostate cancer. In Drosophila, CHD1 is important for fertility and wing development, and overexpression of CHD1 leads to severe wing vein defect phenotypes. The Linker Histone H1, which is known for maintaining heterochromatin and is associated with inactive genes, had been previously identified as a possible functional partner of CHD1, though the exact nature of their interaction is unclear. I undertook a genetic approach to examining the …


Will There Be Changes In Sexually Differentiated Behaviors In Mice Manipulated For The Sry Gene As They Mature Into Adultood?, Subin Joo Jan 2021

Will There Be Changes In Sexually Differentiated Behaviors In Mice Manipulated For The Sry Gene As They Mature Into Adultood?, Subin Joo

CMC Senior Theses

Sexually differentiated behavior has been shown to be affected by both genes and hormones. The discovery of the SRY gene, which codes for the development of testes, lead to the development of the Four Core Genotypes model of mice, and the separation of sex chromosomes and its resulting gonadal hormones. Using the FCG model, this study aims to look at the development of sexually differentiated behavior in mice, and track how it changes throughout their life. FCG mice will be divided into individual and social housing, and repeated experiments carried out to test their reaction to both intact female and …
