情報 Rapamycin (Sirolimus) は、特定のmTOR阻害剤で、IC50 が ~0.1 nMです。



~0.1 nM [1]

In vitro試験 Rapamycin inhibits endogenous mTOR activity in HEK293 cells with IC50 of ~0.1 nM, more potently than iRap and AP21967 with IC50 of ~5 nM and ~10 nM, respectively. [1] In Saccharomyces cerevisiae, Rapamycin treatment induces a severe G1/S cell cycle arrest and inhibition of translation initiation to levels below 20% of control. [2] Rapamycin significantly inhibits the cell viability of T98G and U87-MG in a dose-dependent manner with IC50 of 2 nM and 1 μM, respectively, while displaying little activity against U373-MG cells with IC50 of >25 μM despite the similar extent of the inhibition of mTOR signaling. Rapamycin (100 nM) induces G1 arrest and autophagy but not apoptosis in Rapamycin-sensitive U87-MG and T98G cells by inhibiting the function of mTOR. [3]
In vivo試験 Treatment with Rapamycin in vivo specifically blocks targets known to be downstream of mTOR such as the phosphorylation and activation of p70S6K and the release of inhibition of eIF4E by PHAS-1/4E-BP1, leading to complete blockage of the hypertrophic increases in plantaris muscle weight and fibre size. [4] Short-term Rapamycin treatment, even at the lowest dose of 0.16 mg/kg, produces profound inhibition of p70S6K activity, which correlates with increased tumor cell death and necrosis of the Eker renal tumors. [5] Rapamycin inhibits metastatic tumor growth and angiogenesis in CT-26 xenograft models by reducing the production of VEGF and blockage of VEGF-induced endothelial cell signaling. [6] Rapamycin treatment at 4 mg/kg/day significantly reduces tumor growth of C6 xenografts, and tumor vascular permeability. [7]
臨床試験 A Phase II study of Rapamycin to erase angiofibromas in patients with Tuberous Sclerosis Complex (TSC) is currently ongoing.

Immunoblotting for the mTOR kinase assay HEK293 cells are plated at 2-2.5×105 cells/well of a 12-well plate and serum-starved for 24 hours in DMEM. Cells are treated with increasing concentrations of Rapamycin (0.05-50 nM) for 15 minutes at 37 °C. Serum is added to a final concentration of 20% for 30 minutes at 37 °C. Cells are lysed, and cell lysates are separated by SDS-PAGE. Resolved proteins are transferred to a polyvinylidene difluoride membrane and immunoblotted with a phosphospecific primary antibody against Thr-389 of p70 S6 kinase. Data are analyzed using ImageQuant and KaleidaGr



細胞系 U87-MG, T98G, and U373-MG
濃度 Dissolved in DMSO, final concentrations ~25 μM
処理時間 72 hours

Cells are exposed to various concentrations of Rapamycin for 72 hours. For the assessment of cell viability, cells are collected by trypsinization, stained with trypan blue, and the viable cells in each well are counted. For the determination of cell cycle, cells are trypsinized, fixed with 70% ethanol, and stained with propidium iodide using a flow cytometry reagent set. Samples are analyzed for DNA content using a FACScan flow cytometer and CellQuest software. For apoptosis detection, cells are stained with the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) technique using an ApopTag apoptosis detection kit. To detect the development of acidic vesicular organelles (AVO), cells are stained with acridine orange (1 μg/mL) for 15 minutes, and examined under a fluorescence microscope. To quantify the development of AVOs, cells are stained with acridine orange (1 μg/mL) for 15 minutes, removed from the plate with trypsin-EDTA, and analyzed using the FACScan flow cytometer and CellQuest software. To analyze the autophagic process, cells are incubated for 10 minutes with 0.05 mM monodansylcadaverine at 37 °C and are then observed under a fluorescence microscope.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Results These data suggest that CaPs with AR loss have greater reliance upon the PI3K/AKT/mTOR-signaling pathways and that combined AR/androgen blockage in conjunction with PI3K/AKT/mTOR inhibition (by Rapamycin) is more effective for CaPs initiated by PTEN loss or PI3K/AKT activation.

Results To determine the effect of rapamycin, an mTOR inhibitor, in the OA-induced fatty liver, rats were fed 1% OA and administered rapamycin for seven days. OA-induced lipid accumulation was completely inhibited by the treatment with rapamycin (Fig. A). HE and Oil Red O staining of liver sections clearly confi rmed the results (Fig. B). Immunohistochemistry analyses showed signifi cantly repressed SREBP-1 in the rapamycin-cotreatment liver ( Fig. B ). All the downstream effectors of SREBP-1, such as Lxr-α, Acc, Scd-1 and Fas, were consistently suppressed by rapamycin ( Fig. C ).

Results RAD001 and other mTOR inhibitors decreased the levels of survivin protein, as assessed by Western blot analysis, without affecting the levels of other IAP members. In addition, combined treatment with sorafenib and mTOR inhibitor Rapamycin and RAD001 decreased survivin expression to a greater extent than treatment with either alone.
