It is well established that prolactin (PRL) sustains, while prostaglandin F(2 alpha) (PGF(2 alpha)) curtails, progesterone production by the rat corpus luteum (CL). We have previously shown that the actions of both molecules converge on the 20 alpha-HSD gene and control its expression in a dramatically opposed manner. In this investigation, we have found twelve more genes that are inversely regulated by PRL and PGF(2 alpha). In addition to 20 alpha-HSD, PGF(2 alpha) stimulated and PRL inhibited PGF(2 alpha)-receptor, phospholipase C delta(1) and TGF beta(1) expression. In contrast PRL stimulated and PGF(2 alpha) inhibited the LH receptor, 11 beta-HSD2, sterol carrier protein 2, mitochondrial glutathione S-transferase (GST), GST mu(2), inhibitory DNA-binding proteins 1, 2, and 3, and calcium binding protein 2. We have also identified new target genes for PRL and PGF(2 alpha). PGF(2 alpha) stimulated the expression of genes involved in cell signaling such as cell adhesion kinase-beta, ERK3, FRA2, IL-2 receptor, and 14-3-3 proteins. PGF(2 alpha) also up-regulated the expression of the sodium channel beta(1), Na/K ATPase, annexin IV, GST7pi, and P450 reductase. In contrast PGF(2 alpha) inhibited the expression of two genes involved in cell cycle: cyclin D2 and retinoblastoma related protein (Rb2/p130). It also inhibited genes involved in estradiol (P-450(AROM)) and cholesterol biosynthesis (HMG-CoA synthase), as well as genes involved in tissue remodeling: VEGF and TIMP3. PRL had a profound inhibitory effect on the expression of genes encoding the ADP-ribosylation factor 3, annexin V and c-jun, yet increased the expression of P450scc, 3beta-HSD, and SR-B1 (HDL-receptor), all genes involved in steroidogenesis. PRL also stimulated the expression of beta(2)-microglobulin, TIMP2, cytochrome c oxidase IV, cathepsin H and L, and copper-zinc superoxide dismutase as well as elongation factor SIII, heat shock protein-60 and mitochondrial ATP synthase-D. In conclusion, this investigation has revealed a "yin-yang" relationship between PRL and PGF(2 alpha) in regulating certain critical genes in the rodent CL, and has demonstrated novel regulation by these factors of other important genes involved in luteal function.

This study presents the first prospective multicenter study assessing sirolimus-based immunosuppression with early (4-day) corticosteroid withdrawal (CSWD) in renal transplantation. Immunosuppression included: anti-IL-2 receptor antibody and tacrolimus/sirolimus. Inclusion criteria included adult primary recipients. Exclusion criteria included: (i) African Americans, (ii) current PRA >50%, (iii) multiple organ transplants, (iv) WBC < 3000 cells/microL and (v) fasting hypercholesterolemia/hypertriglyceridemia. The primary endpoints were acute rejection and the proportion of patients off corticosteroids. Seventy-seven patients were enrolled: mean age of 49.7 +/- 12 years. Transplants included: cadaveric (26%) and living donor (74%). Patient and graft survival were 100%. Biopsy proven acute rejection occurred in 13%; presumptive rejection in 10.5%. Banff grades included: IA (seven patients), IB (one patient), IIA (one patient) and IIB (one patient). Renal function at 1 year: serum creatinine (1.18 +/- 0.06 mg/dL). Mean weight gain was minimal at 1 year: 3 +/- 2 kg/patient. Mild increases in total, LDL and HDL cholesterol were observed and new antilipid agent use occurred in 26 patients. In conclusion, early CSWD under tacrolimus/sirolimus-based immunosuppression in selected, low-risk renal transplant recipients provides: (i) excellent patient and graft survival, (ii) good renal function, (iii) reduced hyperlipidemia and antilipid agent use and (iv) low acute rejection rates.
