Conference Paper
MDM4 and topoisomerase IIα (TOP2A) are important cancer-related factors. MDM4 acts as an oncoprotein promoting cancer progression by inhibiting tumor suppressor p53. As a DNA replication- and cell division-regulating enzyme, TOP2A is the main target of many anticancer therapy regimens, even though the exact role of TOP2A in cancer remains elusive....
Data
Fig. S1. Expression of MDM4 is associated with TOP2A protein expression in cancer cells. Fig. S2. The CTR of TOP2A interacts to a unique sequence (188–238) of MDM4.

MDM4 and topoisomerase IIα (TOP2A) are over‐expressed in various human cancers. MDM4 acts as an oncoprotein which promotes cancer progression by inhibiting tumor suppressor p53. As a DNA replication‐ and cell division‐regulating enzyme, TOP2A is the main target of many anticancer therapy regimens; however, the exact role of TOP2A in cancer remains...
Article
A novel small-molecule anthraquinone (AQ) analog, AQ-101, which was synthesized through chemical modification of the core structures of rhein, exhibited potent anticancer activity. In the present study, we evaluated the cancer-inhibiting mechanism of AQ-101 and tested the therapeutic potential of this compound for treating cancer in mice. We found...
Article
Nucleophosmin (NPM1), a restricted nucleolar localization protein, shuttles between the nucleus and the cytoplasm. Mutated (Mt)-NPM1 protein, which has aberrant cytoplasmic dislocation of nucleophosmin, occurs in approximately one-third of acute myeloid leukemia cases. Deguelin, a rotenoid isolated from several plant species, is a strong antitumor...
Article
Acute myeloid leukemia (AML) is a genetically heterogeneous malignancy due to abnormal proliferation of hematopoietic progenitor cells, with difficulty in treatment and high mortality. Nucleophosmin 1 (NPM1), a restricted nucleolar localization protein, shuttles between nucleus and cytoplasm. NPM1-mutant protein, aberrant cytoplasmic dislocation of...
Article
MDM2 and XIAP are mutually regulated. Binding of MDM2 RING protein to the IRES region on XIAP mRNA results in MDM2 protein stabilization and enhanced XIAP translation. In this study, we developed a protein-RNA fluorescence polarization (FP) assay for high-throughput screening (HTS) of chemical libraries. Our FP-HTS identified eight inhibitors that...

The FK506-binding protein 12 (FKBP12) is a cytoplasmic protein and has been reported to possess multiple functions in signaling transduction based on its interaction with different cellular targets. Here, we report that FKBP12 interacts with oncoprotein MDM2 and induces MDM2 degradation. We demonstrate that FKBP12 degrades MDM2 through binding to M...
Article
Gambogic acid (GA), the active ingredient from gamboges, has been verified as a potent anti-tumor agent in many cancer cells. Nevertheless, its function in lymphoma, especially in B-cell Non-Hodgkin lymphoma (NHL), remains unclear. Amplification and/or overexpression of steroid receptor coactivator-3 (SRC-3) have been detected in multiple tumors an...
Article
Steroid receptor coactivator-3 (SRC-3) mediates the transcriptional functions of nuclear receptors and other transcription factors, regulating the cell proliferation, survival and growth. SRC-3 amplification or overexpression, detected in many hormone-dependent or -independent tumors, has been demonstrated its important role in promoting carcinogen...

It is known that the MDM2 protein is stabilized when it forms a heterodimer with its partner MDM4, but MDM2 protein stability in its homodimer form is not known. The MDM2 protein contains a C-terminal RING domain that not only functions as an E3 ligase to regulate ubiquitination of p53 and MDM2 itself, but also is characterized to be able to bind s...
Article
As the principal active ingredient in the Chinese herb Tripterygium wilfordii Hook.F (TwHF), triptolide has been shown to have very strong antitumor properties. The trimethylation of lysine 4 on histone H3 (H3K4me3) has been proposed to promote gene expression, and the accumulation of H3K4me3 at the transcriptional start sites of oncogenes is invol...
Article
The MYCN oncogene is amplified in 20% of neuroblastomas, leading to its overexpression at both the mRNA and protein levels. MYCN overexpression is strongly associated with advanced disease stage, rapid tumor progression and a worse prognosis. In the present study, we identified microRNA-375 (miR-375) as a negative regulator of MYCN: enforced expres...
Article
AML with Mt NPM1 has relatively good responses to induction therapy. However, a proportion of NPMc+ AML cells cannot be cleared by conventional treatments. Therefore, we determined the therapeutic efficacy of deguelin that has demonstrated extensive biological activity with low toxicity. We previously reported that deguelin selectively reduces Mt N...
Article
Nucleophosmin (NPM1) is a multifunctional protein that functions as a molecular chaperone, shuttling between the nucleolus and the cytoplasm. In up to one third of patients with acute myeloid leukemia, mutation of NPM1 results in the aberrant cytoplasmic accumulation of mutant protein and is thought to be responsible for leukemogenesis. Deguelin, a...
Article
Aim: Skewed cytoplasmic accumulation of NPM mutant protein (NPM1c+) is close related to leukemia pathogenesis. The aim of this study was to investigate whether oridonin, a diterpenoid isolated from the Chinese traditional medicine Rabdosia rubescens, was able to interfere with NPM1c+ protein trafficking and induce apoptosis in NPM1c+ acute myeloid...
Article
2435 Acute myeloid leukemia (AML) carrying nucleophosmin (NPM1) gene mutations, leading to aberrant cytoplasmic expression of the nucleolar protein NPM1, accounts for about one-third of adult AML and shows distinctive biological and clinical features. In spite of the relatively good prognosis of NPM1-mutated AML, there are still cases that show poo...

Connexins (Cxs), a conserved family of trans-membrane proteins, function in the organization of cell-cell communicatin via gap junctions in multicellular organisms. However, the role of Cxs in acute myeloid leukemia (AML) is poorly understood. In this study, we investigated the relationship between cell proliferation and expression of connexin 43 (...

Aim: To investigate the effects of betulinic acid (BA) on apoptosis and autophagic flux in multiple myeloma cells and the relationship between the two processes. Methods: The proliferation of human multiple myeloma KM3 cells was measured with MTT assay. FITC/PI double-labeled flow cytometry (FCM) and Hoechst 33258 staining were used to analyze the...
Article
Objective: To elucidate the effects of triptolide on histone demethylase in multiple myeloma U266 cell and to investigate its epigenetic regulation. Methods: The inhibition of triptolide on U266 cell proliferation was studied by MTT assay. Apoptosis was evaluated by Annexin-V-FITC/PI-labeled flow cytometry. The changes of mRNA expression of histone...
Article
Oridonin has been utilized for the treatment of various human diseases due to its anti-inflammatory, antibacterial and antitumor effects. However, the precise mechanisms induced by oridonin in human erythroleukemia are yet to be clarified. The present study aimed to elucidate possible oridonin‑induced apoptotic mechanisms in OCIM2 cells, as well as...

Multiple myeloma (MM) is the second most commonly diagnosed hematologic malignancy. Although new drugs, including bortezomib and lenalidomide, have improved the treatment landscape for MM patients, MM remains incurable. Therefore, screening for novel anti-myeloma drugs is necessary. Gambogic acid (GA), the main active ingredient of gamboges secrete...
Article
The absence of researches about autophagy in multiple myeloma promoted us to explore the biological characteristics and role of autophagy induced by nutrient depletion in multiple myeloma (MM) cell line RPMI8226 cells. Both autophagic and apoptotic morphology were observed by TUNEL, transmission electron microscopy (TEM), and monodansylcadervarine...
