Kdm6b Is Required For Self-Renewal Of Normal And Leukemic Mouse Stem Cells Under Proliferative Stress, Cates Mallaney
Arts & Sciences Electronic Theses and Dissertations
KDM6B (JMJD3) is one of two known epigenetic modifiers responsible for the removal of the repressive histone mark, histone-3 lysine-27 trimethylation (H3K27me3), and has been shown to play a role in development, differentiation, and inflammatory stress response. Unlike the other H3K27me3 demethylase, UTX (KDM6A), which is frequently mutated in hematopoietic malignancies, KDM6B is upregulated in a myriad of blood disorders. This suggests that it may have important functions in the pathogenesis of hematopoietic cancers. Here, we examined the role of Kdm6b in hematopoietic stem cell (HSC) fate decisions under normal and malignant conditions to evaluate its potential as a therapeutic …
Transcriptional Signatures Of Host Susceptibility In Urinary Tract Infections, Lu Yu
Transcriptional Signatures Of Host Susceptibility In Urinary Tract Infections, Lu Yu
Arts & Sciences Electronic Theses and Dissertations
Urinary tract infections (UTI) caused by uropathogenic Escherichia coli (UPEC) are common and highly recurrent. Two important non-behavioral risk factors for UTI in women are genetics and history of two or more episodes of previous UTI. However, specific mechanisms of how these two factors modulate host susceptibility to UTI remain unclear. Concordantly, inbred mice of various genotypes and with different infection histories exhibit different susceptibilities to acute and chronic bladder infection (cystitis), which recapitulates a range of clinical UTI outcomes observed in women. Early host-pathogen interactions have been shown to determine UTI outcomes in mouse models. Here, we used two …
