Hyperglycemic agents with complementary mechanisms of action allows greater glycemic control with lower doses of either agent. Clinical combinations commonly used to treat patients with type 2 diabetes include metformin plus sulfonylurea DeFronzo 1995; Garber 1997 ; , metformin plus repaglinide Moses 1999 ; , metformin plus pioglitazone or rosiglitazone Egan 1999; Einhorn 2000; Fonseca 1999 ; , sulfonylurea plus pioglitazone Kipnes 2001; Schneider 1999 ; , metformin plus acarbose Halimi 2000; Rosenstock 1998 ; , and sulfonylurea plus acarbose Bayraktar 1996; Willms 1999 ; . The most frequently used combination is metformin plus a sulfonylurea DeFronzo 1999 ; . Several studies have shown that this combination provides greater glycemic control than either agent alone, with no increase in adverse events Erle 1999; Hermann 1994; UKPDS 1998a; UKPDS 1998b ; . The single-tablet formulation of a sulfonylurea glyburide ; plus metformin has been approved by the Food and Drug Administration and is likely to simplify treatment of type 2 diabetes. The glyburide metformin tablet was developed using a formulation of glyburide of controlled particle size that delivers twice as much of the agent during the first 3 hours of dosing than does glyburide coadministered with metformin. Recently, a combination of metformin plus glipizide was introduced Donahue 2002 ; . The use of single-tablet glyburide metformin was evaluated in a large, 32-week, double-blind, placebo-controlled clinical trial of pa.

Dana-Farber Cancer Institute, Boston, MA ; . GST-PPAR was produced using a baculovirus expression system. A cDNA expressing full-length PPAR was cloned into a pAcGHLT baculovirus expression plasmid Pharmingen ; . Sf21 cells were infected with the baculovirus expressing GST-PPAR for 2 d and then harvested into lysis buffer. GST-PPAR protein was isolated by incubation with GSH-Sepharose beads and protein quantified by Commassie blue staining. Affinity purification was performed using 1 g GST-PPAR protein with cell lysate from Bosc cells transfected full-length gfp-Hic-5 or an N-terminal or C-terminal gfp-Hic-5 deletion constructs gfp-Nterm and gfp-Cterm, respectively ; as shown in Figure 1C a kind gift from Drs. Nose and Shibanuma, Showa University School of Pharmaceutical Sciences, Tokyo, Japan ; Fujita et al. 1998 ; . Briefly, GST-PPAR bound to GSH beads was incubated for 2 h with cell lysates at 25C. Beads were washed and proteins resolved on an 8% SDS gel. Proteins were transferred to PVDF and immunoblotted using an antibody against gfp a kind gift from Dr. Pam Silver ; . Mapping of Hic-5 domains that interact with PPAR was performed by using full-length Hic-5 or Hic-5 deletion constructs, as shown in Figure 1D a kind gift from Drs. Nose and Shibanuma ; , or SRC-1 as a positive control. Proteins were translated in vitro in the presence of 35S-methionine according to manufacturer protocol Promega ; . GST-PPAR bound to GSH beads was incubated with in vitro translated protein in binding buffer at room temperature for 1 h. Following washing, proteins were eluted and resolved on a 4%12% gel Invitrogen ; by PAGE. Gels were dried down and exposed to film. Retroviral preparation and infections A full-length Hic-5 cDNA was generated by RTPCR from mouse spleen RNA using Invitrogens TOPO cloning kit. The resulting cDNA was sequenced and subsequently cloned into a pMSCV retroviral vector Clontech ; . siRNA against Hic-5 was designed using Oligoengines online design program. The 293T packaging cell line was transfected using Lipofectamine 2000 Invitrogen ; . Cells were transfected with expression vectors for vsv and gag-pol and with the following retroviral vectors: pBabe expressing gfp, gfp-Hic-5, or gfp-Nterm, pmscv-puro, pmscvpuro expressing Hic-5, pSuperRetro-neo control, or pSuperRetro-neo siRNA against Hic-5. After 612 h, media was replaced, and cells were transferred to 33C for 2472 h. Viral supernatants were collected and filtered. Moser or 3T3-L1 cells were plated and infected on the following day with the viral supernatants and 8 g mL polybrene. 3T3-L1 cells were subjected to a differentiation protocol when confluent see below ; . Moser cells were split 1: 3 and selected with either puromycin or neomycin for 1 wk, or sorted for gfp-expressing cells. Adipocyte differentiation and Oil-Red-O staining For differentiation assays, confluent 3T3-L1 cells infected with control or Hic-5 expressing retrovirus were treated with or without 1 M rosiglitazone plus 0.5 mM 3-isobutyl-1-methylxanthine, 5 g mL insulin, and 1 M dexamethasone for 2 d.

Rosiglitazone and heart attack
Patients was observed. These data, although obtained in a very small series of tumors, might suggest that the levels of receptor expression in pituitary tumors did not represent the critical event determining the variable inhibition of cortisol secretion induced by PPAR-g agonists. In our experience, apart from the expected improvement of glucose metabolism in two diabetic patients, some clinical features showed only a tendency to slow regression. Finally, it is conceivable that the long-term effectiveness of rosihlitazone on hormone secretion might also be due to the induction of G0 G1 cell-cycle arrest and apoptosis by PPAR-g ligands, as shown in secreting and nonfunctioning pituitary adenomas 13 ; . It relevant that before starting the chronic administration of rosigliatzone to hypercortisolemic patients, the acute effects of the thiazolidinedione compound on ACTH and cortisol secretion were evaluated 11 ; and, interestingly, no significant hormonal changes were observed. The biochemical efficacy of rosiglitaznoe in some patients in whom the acute administration of the drug was unable to reduce ACTH cortisol levels 11 ; further confirms that the hypothalamic pituitary adrenal axis response to acute testing is often misleading. Thus, when dealing with neuromodulatory compounds meant to reduce corticotropin secretion, it is noteworthy that no predictive criteria for therapeutic outcome can be given. In conclusion, the documented effects of PPAR-g agonists on steroidogenesis and on the peripheral activity of cortisol suggest that the effectiveness of this drug in the treatment of Cushing's disease needs a more extensive evaluation through a randomized and controlled study. Interestingly, our data show that, at least in some patients, there is a favorable response to rosiglitazone in terms of hormonal modifications, but the value of the drug in the management of ACTHdependent Cushing's disease is far from being proved. However, its administration may be attempted as an adjunctive tool in cases of unsuccessful surgery or if the patient cannot safely undergo operation.
