Abstract
Neomorphic IDH2R140Q mutation is commonly found in acute myeloid leukemia (AML), and inhibiting its activity has been validated as an effective treatment for AML. Herein, we report a series of highly potent and selective IDH2R140Q inhibitors. Among them, compound 36 was identified as the most promising inhibitor, with an IC50 value of 29 nM and more than 490-fold selectivity over wild-type IDH2. The compound significantly suppressed D2HG production (IC50 = 10 nM) and induced differentiation in TF-1/IDH2R140Q cells. Furthermore, it showed reasonable pharmacokinetic properties with high bioavailability (F = 90.3%) and an appropriate half-life (T1/2 = 6.4 h). In vivo, oral administration of compound 36 at a dose of 25 mg/kg effectively reduced D2HG levels in the tumor of TF-1/IDH2R140Q xenograft mouse model. Besides, compound 36 displayed little effect on the hERG current. These results suggest that compound 36 has the potential to be an efficacious treatment for AML.

Abstract
Advancements in science enable researchers to constantly innovate and create novel biologics. However, the use of non-human animal models during the development of biologics impedes identification of precise in vivo interactions between the human immune system and treatments. Due to lack of this understanding, adverse effects are frequently observed in healthy volunteers and patients exposed to potential biologics during clinical trials. In this study, we evaluated and compared the effects of known immunotoxic biologics, Proleukin®/IL-2 and OKT3 in humanized mice (reconstituted with human fetal cells) to published clinical outcomes. We demonstrated that humanized mice were able to recapitulate in vivo pathological changes and human-specific immune responses, such as elevated cytokine levels and modulated lymphocytes and myeloid subsets. Given the high similarities of immunological side effects observed between humanized mice and clinical studies, this model could be used to assess immunotoxicity of biologics at a pre-clinical stage, without placing research participants and/or patients at risk.

Abstract
With an increasing human population, medical research is pushed to progress into an era of precision therapy. Humanized mice are at the very heart of this new forefront where it is acutely required to decipher human-specific disease pathogenesis and test an array of novel therapeutics. In this review, “humanized” mice are defined as immunodeficient mouse engrafted with functional human biological systems. Over the past decade, researchers have been conscientiously making improvements on the development of humanized mice as a model to closely recapitulate disease pathogenesis and drug mechanisms in humans. Currently, literature is rife with descriptions of novel and innovative humanized mouse models that hold a significant promise to become a panacea for drug innovations to treat and control conditions such as infectious disease and cancer. This review will focus on the background of humanized mice, diseases, and human-specific therapeutics tested on this platform as well as solutions to improve humanized mice for future clinical use.

Abstract
Humanized mouse models that have received human cells or tissue transplants are extremely useful in basic and applied human disease research. Highly immunodeficient mice, which do not reject xenografts and support cell and tissue differentiation and growth, are indispensable for generating additional appropriate models. Since the early 2000s, a series of immunodeficient mice appropriate for generating humanized mice has been successively developed by introducing the IL-2Rγ(null) gene (e.g., NOD/SCID/γc(null) and Rag2(null)γc(null) mice). These strains show not only a high rate of human cell engraftment, but also generate well-differentiated multilineage human hematopoietic cells after human hematopoietic stem cell (HSC) transplantation. These humanized mice facilitate the analysis of human hematology and immunology in vivo. However, human hematopoietic cells developed from HSCs are not always phenotypically and functionally identical to those in humans. More recently, a new series of immunodeficient mice compensates for these disadvantages. These mice were generated by genetically introducing human cytokine genes into NOD/SCID/γc(null) and Rag2(null)γc(null) mice. In this review, we describe the current knowledge of human hematopoietic cells developed in these mice. Various human disease mouse models using these humanized mice are summarized.

Abstract
We have developed an in vivo model of differentiated human acute myeloid leukemia (AML) by retroviral infection of the cytokine-dependent AML cell line TF-1 with the v-Src oncogene. When injected either intravenously or intraperitoneally into 300 cGy irradiated SCID mice, animals formed multiple granulocytic sarcomas involving the adrenals, kidneys, lymph nodes and other organs. The mean survival time was 34+/-10 days (n = 40) after intravenous injection and 24+/-3 days (n = 5) after intraperitoneal injection of 20 million cells. The cells recovered from leukemic animals continued to express interleukin-3 receptors and remained sensitive to the diphtheria fusion protein DT388IL3. Further, these granulocytic sarcoma-derived cells grew again in irradiated SCID mice (n = 10). The cytogenetic abnormalities observed prior to inoculation in mice were stably present after in vivo passage. Similar to the results with v-Src transfected TF-1 cells, in vivo leukemic growth was observed with TF-1 cells transfected with the human granulocyte-macrophage colony-stimulating factor gene (n = 5) and with TF-1 cells recovered from subcutaneous tumors in nude mice (n = 5). In contrast, TF-1 cells expressing v-Ha-Ras (n = 5), BCR-ABL (n = 5), or activated Raf-1 (n = 44) did not grow in irradiated SCID mice. This is a unique, reproducible model for in vivo growth of a differentiated human acute myeloid leukemia and may be useful in the assessment of anti-leukemic therapeutics which have human-specific molecular targets such as the interleukin-3 receptor.

Abstract
Recent clinical studies in China and USA showed that arsenic trioxide (As2O3) is an effective treatment of acute promyelocytic leukemia (APL) patients refractory to all-trans retinoic acid (RA). We here investigate the effects of As2O3 on RA-resistant APL in vivo and in vitro using our RA-resistant APL model system. As2O3 can induce inhibition of cellular growth of both RA-sensitive NB4 and RA-resistant UF-1 APL cells via induction of apoptosis in vitro. The expression of BCL-2 protein decreased in a dose- and time-dependent manner in NB4 cells. Interestingly, the levels of BCL-2 protein were not modulated by As2O3, but it did upregulate BAX protein in UF-1 cells. UF-1 cells (1x10(7)) were transplanted into hGM-CSF-producing transgenic SCID mice and successfully formed subcutaneous tumors. After 40 days of implantation, mice were treated with As2O3, all-trans RA and PBS for 21 days. In all-trans RA- and PBS-treated mice, tumors grew rapidly, with a 4.5-fold increase in volume at day 21 compared to the initial size. In marked contrast, tumor size was decreased to half of the initial size by the treatment of As2O3, which resulted in cells with the typical appearance of apoptosis. Interestingly, one of the As2O3-treated mice showed mature granulocytes in the diminished tumor, suggesting that As2O3 had dual effects on RA-resistant APL cells in vivo: both inducing apoptosis and differentiation of the leukemic cells. We conclude that our RA-resistant APL model will be useful for evaluating novel therapeutic approaches to patients with RA-resistant APL, and for further investigation of the metabolism of As2O3 in vivo.
