    Abstract Agents that inhibit bromodomain and extra-terminal domain (BET) proteins have been actively tested in the clinic as potential anticancer drugs. NEDD8-activating enzyme (NAE) inhibitors, represented by MLN4924, target the only activation enzyme in the neddylation pathway that has been identified as an attractive target for cancer therapy. In this study, we focus on the combination of BET inhibitors (BETis) and NAE inhibitors (NAEis) as a cancer therapeutic strategy and investigate its underlying mechanisms to explore and expand the application scope of both types of drugs. The results showed that this combination synergistically inhibited the proliferative activity of tumor cells from different tissues. Compared to a single drug, combination therapy had a weak effect on cycle arrest but significantly enhanced cell apoptosis. Furthermore, the growth of NCI-H1975 xenografts in nude mice was significantly inhibited by the combination without obvious body weight loss. Research on the synergistic mechanism demonstrated that combination therapy significantly increased the mRNA and protein levels of the proapoptotic gene BIM. The inhibition and knockout of BIM significantly attenuated the apoptosis induced by the combination, whereas the re-expression of BIM restored the synergistic effects, indicating that BIM induction plays a critical role in mediating the enhanced apoptosis induced by the co-inhibition of BET and NAE. Together, the enhanced transcription mediated by miR-17-92 cluster inhibition and reduced degradation promoted the increase in BIM levels, resulting in a synergistic effect. Collectively, these findings highlight the need for further clinical investigation into the combination of BETi and NAEi as a promising strategy for cancer therapy.

    Abstract Inhibitors targeting bromodomain and extraterminal (BET) proteins are promising anticancer drugs. The emergence of drug resistance during treatments will impair their therapeutic effectiveness. To investigate the mechanisms of acquired resistance to BET inhibitors (BETi), we generated a series of drug-resistant sublines by exposing non-small cell lung cancer (NSCLC) NCI-H1975 cells to the BETi ABBV-075. These sublines displayed cross-resistance to other tested BETis, increased migration abilities, reduced growth rates accompanied by an increased proportion of cells in G1 phase and decreased apoptotic responses to BETis. Changes in RNA expression and gene mutation profiles in the resistant variants indicate that emergence of BETi resistance is multifactorial. Importantly, all the tested ABBV-075-resistant variants showed loss of vesicular overexpressed in cancer prosurvival protein 1 (VOPP1) and an increase in the antiapoptotic BCL-2 protein. By knockdown, knockout, and reconstitution of VOPP1 in resistant cells, their parental cells, and other NSCLC cells, we confirmed that the loss of VOPP1 contributed to BETi resistance. Moreover, knockout of VOPP1 in the parental cells caused the increased expression of BCL-2, and the latter directly mediated BETi resistance. Through combined treatments with BETis and BCL-2 inhibitors (BCL-2i), we demonstrated that BCL-2is synergistically sensitized resistant cells to BETis.
    Implications: Based on these results, for the first time, we establish a causal link from VOPP1 loss to BCL-2 gain and then to BETi resistance, which provides new insights into BETi resistance and paves the way for further testing to circumvent BETi resistance.

    Abstract Ecto-5'-nucleotidase (CD73), encoded by the NT5E gene, mediates tumor immunosuppression and has been targeted for the development of new anticancer drugs. Proteasome inhibitors impair protein degradation by inhibiting proteasome and have been used in the clinic for cancer therapy. Here we report that proteasome inhibitors reduce the protein and mRNA levels of CD73. Among 127 tested small-molecule drugs, proteasome inhibitors were found to consistently decrease the protein and mRNA levels of CD73 in NSCLC NCI-H1299 cells. This effect was further confirmed in different NSCLC cells exposed to different proteasome inhibitors. In those treated cells, the protein levels of ERK and its active form p-ERK, the vital components in the MAPK pathway, were reduced. Consistently, inhibitors of MEK and ERK, another two members of the MAPK pathway, also lowered the protein and mRNA levels of CD73. Correspondingly, treatments with fibroblast growth factor 2 (FGF2), an activator of the MAPK pathway, enhanced the levels of p-ERK and partly rescued the proteasome inhibitor-driven reduction of CD73 mRNA and protein in NSCLC cells. However, exogenous CD73 overexpression in murine Lewis lung carcinoma (LLC) cells was not lowered either in vitro or in vivo, by the treatments with proteasome inhibitors and basically, did not affect their in vitro proliferative inhibition either. In contrast, CD73 overexpression dramatically reduced the in vivo anticancer activity of Bortezomib in immunocompetent mice, with tumor growth inhibition rates from 52.18 % for LLC/vector down to 8.75 % for LLC/NT5E homografts. These findings give new insights into the anticancer mechanisms of proteasome inhibitors.

    Abstract Colorectal cancer (CRC) is an aggressive malignancy with limited options for treatment. Targeting the bromodomain and extra terminal domain (BET) proteins by using BET inhibitors (BETis) could effectively interrupt the interaction with acetylated histones, inhibit genes transcription and have shown a certain effect on CRC inhibition. To improve the efficacy, the inhibitors of Tankyrases, which cause accumulation of AXIN through dePARsylation, in turn facilitate the degradation of β-Catenin and suppress the growth of adenomatous polyposis coli (APC)-mutated CRCs, were tested together with BETi as a combination treatment. We examined the effects of BETi and Tankyrases inhibitor (TNKSi) together on the proliferation, cell cycle and apoptosis of human CRCs cell lines with

    Abstract Angiogenesis inhibitors have been successfully used for cancer therapy in the clinic. Many marine-derived natural products and their analogues have been reported to show antiangiogenic activities. Compared with the drugs in the clinic, these agents display interesting characteristics, including diverse sources, unique chemical structures, special modes of action, and distinct activity and toxicity profiles. This review will first provide an overview of the current marine-derived angiogenesis inhibitors based on their primary targets and/or mechanisms of action. Then, the marine-derived antiangiogenic protein kinase inhibitors will be focused on. And finally, the clinical trials of the marine-derived antiangiogenic agents will be discussed, with special emphasis on their application potentials, problems and possible coping strategies in their future development as anticancer drugs.

    Abstract Tanshinone I (Tanshinone-1), a major active principle of Salvia miltiorrhiza (Danshen), has been shown to overcome tumor drug resistance and metastasis. Here we report that tanshinone-1 inhibits angiogenesis. Tanshinone-1 inhibited proliferation, migration and tube formation of vascular endothelial cells, rat aortic ring sprouting and the neovascularization of the chick chorioallantoic membrane in a concentration-dependent manner. In endothelial cells, tanshinone-1 almost completely inhibited phosphorylation of Stat3 at Tyr705 regardless of hypoxia or normoxia but only slightly decreased the hypoxia-induced HIF-1α accumulation. In tumor cells, contrastively, tanshinone-1 could not only make phosphorylation of Stat3 at Tyr705 disappear but also reduce the hypoxia-induced accumulation of HIF-1α to its baseline levels at normoxia. Consequently, VEGF secretion from tumor cells was reduced, which could potentiate the direct inhibition of tanshinone-1 on endothelial cells. Together with its overcoming tumor drug resistance and metastasis, our results reveal unique characteristics of tanshinone-1 and its improved derivatives as promising angiogenesis inhibitors.

    Abstract PARK7 mutations are accountable for the inherited Parkinson's disease. An induced pluripotent stem cell (iPSC) line FJMUUHi001-A was generated by expressing five reprogramming factors, OCT3/4, SOX2, c-MYC, KLF4 and BCL-XL, in peripheral blood mononuclear cells from a 32-year old patient carrying a homozygous mutation of c.189dupA in PARK7. The iPSCs with a normal karyotype had the abilities to differentiate into three germ layers and expressed pluripotency markers without detectable residual plasmids. The cell line FJMUUHi001-A carrying the truncating protein PARK7 could be a useful tool to help comprehend the function of PARK7 in the iPSCs and differentiated cells from them.

    Abstract Bromodomain and extra-terminal domain (BET) family proteins are promising anticancer targets. Most BET inhibitors in clinical trials are monovalent. They competitively bind to one of the bromodomains (BD1 and BD2) in BET proteins and exhibit relatively weak anticancer activity, poor pharmacokinetics, and low metabolic stability. Here, we evaluated the anticancer activity of a novel bivalent BET inhibitor, N2817, which consists of two molecules of the monovalent BET inhibitor 8124-053 connected by a common piperazine ring, rendering a long linker unnecessary. Compared with ABBV-075, one of the potent monovalent BET inhibitors reported to date, N2817 showed greater potency in inhibiting proliferation, arresting cell-cycle, inducing apoptosis, and suppressing the growth of tumor xenografts. Moreover, N2817 showed high metabolic stability, a relatively long half-life, and no brain penetration after oral administration. Additionally, N2817 directly bound and inhibited another BD-containing protein, TAF1 (BD2), as evidenced by a reduction in mRNA and protein levels. TAF1 inhibition contributed to the anticancer effect of N2817. Therefore, this study offers a new paradigm for designing bivalent BET inhibitors and introduces a novel potent bivalent BET inhibitor and a new anticancer mechanism.
