Elucidating the importance and regulation of key enhancers for human MEIS1 expression.

Myeloid ecotropic virus insertion site 1 (MEIS1) is essential for normal hematopoiesis and is a critical factor in the pathogenesis of a large subset of acute myeloid leukemia (AML). Despite the clinical relevance of MEIS1, its regulation is largely unknown. To understand the transcriptional regulatory mechanisms contributing to human MEIS1 expression, we created a knock-in green florescent protein (GFP) reporter system at the endogenous MEIS1 locus in a human AML cell line.

Differential Effects of Extended Exercise and Memantine Treatment on Adult Neurogenesis in Male and Female Rats.

Adult neurogenesis has potential to ameliorate a number of disorders that negatively impact the hippocampus, including age-related cognitive decline, depression, and schizophrenia. A number of treatments enhance adult neurogenesis including exercise, NMDA receptor antagonism, antidepressant drugs and environmental enrichment. Despite the chronic nature of many disorders, most animal studies have only examined the efficacy of neurogenic treatments over short timescales (≤1 month).
