The mobilization of free fatty acids from adipose triacylglycerol (TG) stores requires the activities of triacylglycerol lipases. In this study, we demonstrate that adipose triglyceride lipase (ATGL) and hormone-sensitive lipase (HSL) are the major enzymes contributing to TG breakdown in in vitro assays and in organ cultures of murine white adipose tissue(More)
A permanent cell line arising from a cerebellar medulloblastoma was established and its growth characteristics were investigated. Although the original tumor inoculum failed to take, the cultured cells were readily tumorigenic in nude mice and gave rise to rapidly growing tumors which could be easily subpassaged. The primary tumor showed evidence of both(More)
A series of bifunctional alkylators were tested against the genotypically and phenotypically heterogeneous continuous human medulloblastoma cell lines, TE-671, Daoy, and D283 Med in vitro and against TE-671 and Daoy growing as s.c. and intracranial xenografts in athymic mice. Drugs tested included melphalan, cyclophosphamide, iphosphamide,(More)
Mobilization of fatty acids from stored triacylglycerol (TG) in adipose tissue and skeletal muscle [intramyocellular triacylglycerol (IMTG)] requires activity of lipases. Although exercise training increases the lipolytic capacity of skeletal muscle, the expression of hormone-sensitive lipase (HSL) is not changed. Recently, adipose triglyceride lipase(More)
Embryonic teratocarcinoma mouse cells (P19) and embryonic NIH3T3 fibroblasts were induced chemically to differentiate along neurogenic or myogenic lineages. The expression profiles of Pax7 alternate transcripts were then assessed by RNA isolation and RT-PCR. Only two transcripts, Pax7b and Pax7d, were expressed in the neurogenic lineage. By contrast, in(More)
RATIONALE Hydrolysis of intracellular cholesterol ester (CE) is the key step in the reverse cholesterol transport in macrophage foam cells. We have recently shown that neutral cholesterol ester hydrolase (Nceh)1 and hormone-sensitive lipase (Lipe) are key regulators of this process in mouse macrophages. However, it remains unknown which enzyme is critical(More)
This paper describes a vision-based control system for a tracked mobile robot (an excavator). The system includes several controllers that collaborate to move the mobile vehicle from a starting position to a goal position. First, the path planner designs an optimum path using a predefined elevation map of the work space. Second, a fuzzy logic path-tracking(More)
A series of pyrrolo[2,1,5-cd]indolizine derivatives has been synthesized and evaluated as ligands for the estrogen receptor. Properly substituted mono- and di-hydroxy derivatives showed binding in the low nanomolar range in accordance with their structural resemblance to estrogen.
Structural alterations within the myogenic and neurogenic developmental gene Pax7 which involve TaqI recognition sequences have previously been reported. These alterations are associated with differences in the efficiency of regrowth of damaged skeletal muscle. To identify other structural features of Pax genes which may influence skeletal muscle regrowth,(More)
