Temporal relationships among testosterone production, steroidogenic acute regulatory protein (StAR), and P450 side-chain cleavage enzyme (P450scc) during Leydig cell agingLindi Luo
Department of Biochemistry and Molecular Biology, Division of Reproductive Biology, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD 21205, USA
J Androl 26:25-31. 2005..This suggestion is supported by recent studies from our lab demonstrating that long-term (3 days) culture of old Leydig cells with dbcAMP restored testosterone production to levels approximating those of young cells...
Dibutyryl cyclic adenosine monophosphate restores the ability of aged Leydig cells to produce testosterone at the high levels characteristic of young cellsHaolin Chen
Department of Biochemistry and Molecular Biology, Division of Reproductive Biology, Johns Hopkins University Bloomberg School of Public Health, Baltimore, Maryland 21205, USA
Endocrinology 145:4441-6. 2004..These results strongly suggest that signal transduction deficits are responsible for reduced steroidogenesis by aged Leydig cells and that bypassing signal transduction reverses the steroidogenic decline by the aged cells...

Leydig cell gene expression: effects of age and caloric restrictionHaolin Chen
Division of Reproductive Biology, Department of Biochemistry and Molecular Biology, Bloomberg School of Public Health, Johns Hopkins University, 615 North Wolfe Street, Baltimore, MD 21205, USA
Exp Gerontol 39:31-43. 2004..In contrast to the effects of caloric restriction as seen in many other cell types and systems, the vast majority (44/45) of the Leydig cell genes that changed with age were not 'rescued' by this intervention...
Cholesterol transport, peripheral benzodiazepine receptor, and steroidogenesis in aging Leydig cellsMartine Culty
Department of Cell Biology, Georgetown University School of Medicine, Washington, DC, USA
J Androl 23:439-47. 2002..Taken together, these results suggest that alterations in cholesterol transport and in PBR may play critical roles in age-related decreases in testosterone production in Brown Norway rat Leydig cells...
