Here we modeled T-ALL resistance to Notch inhibition, identifying M-bM-^@M-^XpersisterM-bM-^@M-^Y cells that readily expand in the presence of gamma secretase inhibitor (GSI) and the absence of Notch signaling. Rare persister cells are already present in naM-CM-/ve T-ALL populations, and the reversi...

In embryonic stem (ES) cells, bivalent chromatin domains with overlapping repressive (H3 lysine 27 tri-methylation) and activating (H3 lysine 4 tri-methylation) histone modifications mark the promoters of more than 2000 genes. To gain insight into the structure and function of bivalent domains, we m...

Pancreatic M-CM-^_-cells adapt to compensate for the increased metabolic demand during insulin resistance. While the microRNA pathway has an essential role in the expansion of M-CM-^_-cell mass, the extent of its contribution is unclear. Here we show that miR-184 is silenced in the pancreatic islets...

Plexiform leiomyomata are a histologically defined subgroup of benign uterine smooth muscle tumors based on their epitheliod cytology and abundant extracellular matrix. We used microarrays to compare plexiform leiomyomata to normal myometrium (smooth muscle of the uterine wall), typical leiomyomata,...

Recent analyses of 5-hydroxymethylcytosine (5hmC) suggest that the modified base influences transcription by acting as an intermediate to demethylation. However, elevated levels of 5hmC within neural tissues suggest that the mark is stable and may directly contribute to gene regulation. Here, we cha...

Four male SHR/Ola, BN and SHR-18 rats were fed a normal diet and sacrificed at 9 weeks of age. Four male SHR/Ola and SHR-18 rats at 8 weeks of age were fed 1% NaCl for one week and then sacrificed. Kidneys were removed and frozen in liquid nitrogen for all 20 animals. Total RNA was isolated, labelle...
