Hallmarks Of Stem Cell Aging, Thomas A Rando, Anne Brunet, Margaret A Goodell

Faculty, Staff and Students Publications

As organisms age, somatic stem cells progressively lose their ability to sustain tissue homeostasis and support regeneration. Although stem cells are relatively shielded from some cellular aging mechanisms compared with their differentiated progeny, they remain vulnerable to both intrinsic and extrinsic stressors. In this review, we delineate five cardinal features that characterize aged stem cells and examine how these alterations underlie functional decline across well-studied stem cell compartments. These hallmarks not only provide insight into the aging process but also serve as promising targets for therapeutic strategies aimed at rejuvenating stem cell function and extending tissue health span.

Laterality defects are defined by perturbations in the usual left-right asymmetry of organs. The genetic etiology that underlies congenital heart disease (CHD) is often unknown (less than 40%), so we used a digenic model approach for the identification of contributing variants in known laterality-defect-associated genes (n = 115) in the exome/genome sequencing (ES/GS) data from individuals with clinically diagnosed laterality defects. The unsolved ES/GS data were analyzed from three CHD cohorts: Baylor College of Medicine-Genomics Research to Elucidate the Genetics of Rare Diseases (BCM-GREGoR; n= 251 proband ES), Gabriella Miller Kids First Pediatric Research Program (Kids First; n = 158 …

Synthesis And Evaluation Of Novobiocin Analogues As Potential Inhibitors Of Polymerase Theta Polθ In Dna Damage And Repair, Mohammed Essam Albuhluli

Theses and Dissertations

Killing tumors while leaving normal cells unharmed is the goal of precision cancer therapy, a challenging feat that is enabled by targeting tumor-specific vulnerabilities [1]. Targeting Polθ potentiates PARP inhibitors (PARPi) in specifically killing homology-directed repair (HDR)-deficient tumor cells and re-sensitize PARPi resistant tumor cells [1]. The induced essentiality between Polθ and HDR-deficiency underscores the value of Polθ as a therapeutic target in the context of tumors with HDR genetic mutations [1]. The helicase-like domain (HLD) is a super family 2 (SF2)-type domain with DNA-dependent ATPase activity [1]. We previously discovered that the antibiotic NVB acts as an inhibitor of …
