Abstract
Cytochrome b5 reductase 3 (CYB5R3) is involved in various cellular metabolic processes, including fatty acid synthesis and drug metabolism. However, the role of CYB5R3 in cancer development remains poorly understood. Here, we show that CYB5R3 expression is downregulated in human lung cancer cell lines and tissues. Adenoviral overexpression of CYB5R3 suppresses lung cancer cell growth in vitro and in vivo. However, CYB5R3 deficiency promotes tumorigenesis and metastasis in mouse models. Transcriptome analysis revealed that apoptosis- and endoplasmic reticulum (ER) stress-related genes are upregulated in CYB5R3-overexpressing lung cancer cells. Metabolomic analysis revealed that CYB5R3 overexpression increased the production of nicotinamide adenine dinucleotide (NAD+) and oxidized glutathione (GSSG). Ectopic CYB5R3 is mainly localized in the ER, where CYB5R3-dependent ER stress signaling is induced via activation of protein kinase RNA-like ER kinase (PERK) and inositol-requiring enzyme 1 alpha (IRE1α). Moreover, NAD+ activates poly (ADP-ribose) polymerase16 (PARP16), an ER-resident protein, to promote ADP-ribosylation of PERK and IRE1α and induce ER stress. In addition, CYB5R3 induces the generation of reactive oxygen species and caspase-9-dependent intrinsic cell death. Our findings highlight the importance of CYB5R3 as a tumor suppressor for the development of CYB5R3-based therapeutics for lung cancer.

Abstract
Ferroptosis, a type of cell death induced by lipid peroxidation, has emerged as a novel anti-cancer strategy. Cancer cells frequently acquire resistance to ferroptosis. However, the underlying mechanisms are poorly understood. To address this issue, we conducted a thorough investigation of the genomic and transcriptomic data derived from hundreds of human cancer cell lines and primary tissue samples, with a particular focus on non-small cell lung carcinoma (NSCLC). It was observed that mutations in Kelch-like ECH-associated protein 1 (KEAP1) and subsequent nuclear factor erythroid 2-related factor 2 (NRF2, also known as NFE2L2) activation are strongly associated with ferroptosis resistance in NSCLC. Additionally, AIFM2 gene, which encodes ferroptosis suppressor protein 1 (FSP1), was identified as the gene most significantly correlated with ferroptosis resistance, followed by multiple NRF2 targets. We found that inhibition of NRF2 alone was not sufficient to reduce FSP1 protein levels and promote ferroptosis, whereas FSP1 inhibition effectively sensitized KEAP1-mutant NSCLC cells to ferroptosis. Furthermore, we found that combined inhibition of FSP1 and NRF2 induced ferroptosis more intensely. Our findings imply that FSP1 is a crucial suppressor of ferroptosis whose expression is partially dependent on NRF2 and that synergistically targeting both FSP1 and NRF2 may be a promising strategy for overcoming ferroptosis resistance in cancer.

Abstract
MDH1 and MDH2 enzymes play an important role in the survival of lung cancer. In this study, a novel series of dual MDH1/2 inhibitors for lung cancer was rationally designed and synthesized, and their SAR was carefully investigated. Among the tested compounds, compound 50 containing a piperidine ring displayed an improved growth inhibition of A549 and H460 lung cancer cell lines compared with LW1497. Compound 50 reduced the total ATP content in A549 cells in a dose-dependent manner; it also significantly suppressed the accumulation of hypoxia-inducible factor 1-alpha (HIF-1α) and the expression of HIF-1α target genes such as GLUT1 and pyruvate dehydrogenase kinase 1 (PDK1) in a dose-dependent manner. Furthermore, compound 50 inhibited HIF-1α-regulated CD73 expression under hypoxia in A549 lung cancer cells. Collectively, these results indicate that compound 50 may pave the way for the development of next-generation dual MDH1/2 inhibitors to target lung cancer.

Abstract
Nitroreductase (NTR) has the ability to activate nitro group-containing prodrugs and decompose explosives; thus, the evaluation of NTR activity is specifically important in pharmaceutical and environmental areas. Numerous studies have verified effective fluorescent methods to detect and image NTR activity; however, near-infrared (NIR) fluorescence probes for biological applications are lacking. Thus, in this study, we synthesized novel NIR probes (NIR-HCy-NO2 1-3) by introducing a nitro group to the hemicyanine skeleton to obtain fluorescence images of NTR activity. Additionally, this study was also designed to propose a different water solubility and investigate the catalytic efficiency of NTR. NIR-HCy-NO2 inherently exhibited a low fluorescence background due to the interference of intramolecular charge transfer (ICT) by the nitro group. The conversion from the nitro to amine group by NTR induced a change in the absorbance spectra and lead to the intense enhancement of the fluorescence spectra. When assessing the catalytic efficiency and the limit of detection (LOD), including NTR activity imaging, it was demonstrated that NIR-HCy-NO2 1 was superior to the other two probes. Moreover, we found that NIR-HCy-NO2 1 reacted with type I mitochondrial NTR in live cell imaging. Conclusively, NIR-HCy-NO2 demonstrated a great potential for application in various NTR-related fields, including NTR activity for cell imaging in vivo.

Abstract
Owing to their unique properties and biological activities, ionic liquids (ILs) have attracted research interest in pharmaceutics and medicine. Hypoxia-inducible factor (HIF)- 1α is an attractive cancer drug target involved in cancer malignancy in the hypoxic tumor microenvironment. Herein, we report the inhibitory activity of ILs on the HIF-1α pathway and their mechanism of action. Substitution of a dimethylamino group on pyridinium reduced hypoxia-induced HIF-1α activation. It selectively inhibited the viability of the human colon cancer cell line HCT116, compared to that of the normal fibroblast cell line WI-38. These activities were enhanced by increasing the alkyl chain length in the pyridinium. Under hypoxic conditions, dimethylaminopyridinium reduced the accumulation of HIF-1α and its target genes without affecting the HIF1A mRNA level in cancer cells. It suppressed the oxygen consumption rate and ATP production by directly inhibiting electron transfer chain complex I, which led to enhanced intracellular oxygen content and oxygen-dependent degradation of HIF-1α under hypoxia. These results indicate that dimethylaminopyridinium suppresses the mitochondria and HIF-1α-dependent glucose metabolic pathway in hypoxic cancer cells. This study provides insights into the anticancer activity of pyridinium-based ILs through the regulation of cancer metabolism, making them promising candidates for cancer treatment.

Abstract
Hypoxia inducible factor (HIF)-1α is an important transcription factor regulating cancer metabolism in hypoxic environment. Capsaicin is known to inhibit hypoxia-induced HIF activity in lung cancer. Hence, in this study we tried to elucidate its inhibitory mechanism of action. In lung cancer cells, including H1299, H23, A549, and H2009 cells, capsaicin inhibited cell growth and HIF activation. Under hypoxic conditions, capsaicin reduced the accumulation of HIF-1α protein and the expression of its target genes, including pyruvate dehydrogenase kinase 1 (PDK1) and glucose transporter 1 (GLUT1), with no effect on overall HIF-1α mRNA levels in the H1299 cells. In addition, capsaicin increased intracellular oxygen levels by suppressing mitochondrial respiration, resulting in a reduction of HIF-1α accumulation. Furthermore, mitochondrial ATP production was reduced by capsaicin through the inhibition of mitochondrial respiration in the H1299, H23, A549, and H2009 cells. These results indicate that capsaicin potentially exhibits anticancer therapeutic effects in lung cancer under hypoxic conditions.

Abstract
Carboranes 1 and 2 were designed and synthesized for hydrophobic tag (HyT)-induced degradation of HaloTag fusion proteins. The levels of the hemagglutinin (HA)-HaloTag2-green fluorescent protein (EGFP) stably expressed in Flp-In 293 cells were significantly reduced by HyT13, HyT55, and carboranes 1 and 2, with expression levels of 49, 79, 43, and 65%, respectively, indicating that carborane is an alternative novel hydrophobic tag (HyT) for protein degradation under an intracellular environment. To clarify the mechanism of HyT-induced proteolysis, bovine serum albumin (BSA) was chosen as an extracellular protein and modified with maleimide-conjugated m-carborane (MIC). The measurement of the ζ-potentials and the lysine residue modification with fluorescein isothiocyanate (FITC) of BSA-MIC conjugates suggested that the conjugation of carborane induced the exposure of lysine residues on BSA, resulting in the degradation via ubiquitin E3 ligase-related proteasome pathways in the cell.

Abstract
Amyloid β (Aβ) aggregation inhibitor activity cliff involving a curcumin structure was predicted using the SAR Matrix method on the basis of 697 known Aβ inhibitors from ChEMBL (data set 2487). Among the compounds predicted, compound B was found to possess approximately 100 times higher inhibitory activity toward Aβ aggregation than curcumin. TEM images indicate that compound B induced the shortening of Aβ fibrils and increased the generation of Aβ oligomers in a concentration dependent manner. Furthermore, compound K, in which the methyl ester of compound B was replaced by the tert-butyl ester, possessed low cytotoxicity on N2A cells and attenuated Aβ-induced cytotoxicity, indicating that compound K would have an ability for preventing neurotoxicity caused by Aβ aggregation.

Abstract
Cereblon (CRBN) is a multi-functional protein that acts as a sub-strate receptor of the E3 ligase complex and a molecular chaperone. While CRBN is proposed to function in mitochondria, its specific roles are yet to be established. Here, we showed that knockdown of CRBN triggers oxidative stress and calcium overload in mitochondria, leading to disruption of mitochondrial membrane potential. Notably, long-term CRBN depletion using PROteolysis TArgeting Chimera (PROTAC) induced irreversible mitochondrial dysfunction, resulting in cell death. Our collective findings indicate that CRBN is required for mitochondrial homeostasis in cells.

Abstract
In eukaryotic cells, mitochondria are closely tethered to the endoplasmic reticulum (ER) at sites called mitochondria-associated ER membranes (MAMs). Ca2+ ion and phospholipid transfer occurs at MAMs to support diverse cellular functions. Unlike those in yeast, the protein complexes involved in phospholipid transfer at MAMs in humans have not been identified. Here, we determine the crystal structure of the tetratricopeptide repeat domain of PTPIP51 (PTPIP51_TPR), a mitochondrial protein that interacts with the ER-anchored VAPB protein at MAMs. The structure of PTPIP51_TPR shows an archetypal TPR fold, and an electron density map corresponding to an unidentified lipid-like molecule probably derived from the protein expression host is found in the structure. We reveal functions of PTPIP51 in phospholipid binding/transfer, particularly of phosphatidic acid, in vitro. Depletion of PTPIP51 in cells reduces the mitochondrial cardiolipin level. Additionally, we confirm that the PTPIP51-VAPB interaction is mediated by the FFAT-like motif of PTPIP51 and the MSP domain of VAPB. Our findings suggest that PTPIP51 is a phospholipid transfer protein with a MAM-tethering function.

Abstract
Introduction: Hypoxia-inducible factor (HIF) is a master regulator of oxygen homeostasis. The increased expression of genes targeted by HIF is associated with many human diseases, including ischemic cardiovascular disease, stroke, chronic lung disease, and cancer.Areas covered: This patent survey summarizes the information about patented HIF inhibitors over the last 5 years.Expert opinion: HIF inhibitors have shown promise for the treatment of hypoxic pulmonary hypertension, a circadian rhythm disorder, calcific aortic valve disease, cerebrovascular accident, and heterotopic ossification. In addition, HIF-2α inhibitors can be used for the treatment or prevention of iron overload disorders, Crohn's disease, ulcerative colitis, and thyroid eye disease, or to improve muscle generation and repair. PT2385 completed phase I clinical trials for the treatment of clear cell renal cell carcinoma. It exerted a higher synergistic inhibitory effect on tumor growth in combination with anti-PD-1 antibody, in comparison with each treatment alone, indicating that effective immunotherapy for solid tumors counteracts of the immunosuppression induced by hypoxia. Therefore, considering the effects of hypoxia on cancer cells, stromal cells, and effector immune cells, it is important to develop inhibitors of molecular pathways activated by hypoxia for successful treatments.

Abstract
Hypoxia-inducible factor (HIF)-1 is an important regulator of the cellular response in the hypoxic tumor environment. While searching for HIF inhibitors derived from natural products that act as anticancer agents, we found that Glycyrrhiza uralensis exerts HIF-1 inhibitory activity in hypoxic cancer cells. Among the five components of G. uralensis, licochalcone A was found to potently suppress hypoxia-induced HIF-1α accumulation and expression of HIF-1α target genes, including GLUT1 and PDK1 in HCT116 cells. Licochalcone A also enhances intracellular oxygen content by directly inhibiting mitochondrial respiration, resulting in oxygen-dependent HIF-1α degradation. Hence, licochalcone A may effectively inhibit ATP production, primarily by reducing the mitochondrial respiration-mediated ATP production rate rather than the glycolysis-mediated ATP production rate. This effect subsequently suppresses cancer cell viability, including that of HCT116, H1299, and H322 cells. Consequently, these results suggest that licochalcone A has therapeutic potential in hypoxic cancer cells.

Abstract
Targeting cancer metabolism has emerged as an important cancer therapeutic strategy. Here, we describe the synthesis and biological evaluation of a novel class of hypoxia-inducible factor (HIF)-1α inhibitors, disubstituted adamantyl derivatives. One such compound, LW1564, significantly suppressed HIF-1α accumulation and inhibited the growth of various cancer cell lines, including HepG2, A549, and HCT116. Measurements of the oxygen consumption rate (OCR) and ATP production rate revealed that LW1564 suppressed mitochondrial respiration, thereby increasing the intracellular oxygen concentration to stimulate HIF-1α degradation. LW1564 also significantly decreased overall ATP levels by inhibiting mitochondrial electron transport chain (ETC) complex I and downregulated mammalian target of rapamycin (mTOR) signaling by increasing the AMP/ATP ratio, which increased AMP-activated protein kinase (AMPK) phosphorylation. Consequently, LW1564 promoted the phosphorylation of acetyl-CoA carboxylase, which inhibited lipid synthesis. In addition, LW1564 significantly inhibited tumor growth in a HepG2 mouse xenograft model. Taken together, the results indicate that LW1564 inhibits the growth of cancer cells by targeting mitochondrial ETC complex I and impairing cancer cell metabolism. We, therefore, suggest that LW1564 may be a potent therapeutic agent for a subset of cancers that rely on oxidative phosphorylation for ATP generation. A drug that curbs the accumulation of a critical protein involved in the oxygen-sensing machinery of cells could offer a potent new therapeutic for treating cancer. Inhyub Kim, University of Science and Technology, Daejeon, South Korea, and colleagues describe a compound called LW1564 that suppresses metabolism within mitochondria, the energy factories of the cell. Less energy production means less oxygen consumption and therefore oxygen molecules build up inside the cell, which in turn stimulates the degradation of HIF-1α, a master regulator of oxygen balance. Many tumors rely on HIF-1α for their aberrant biological characteristics, and without this protein they tend to show reduced growth. The authors demonstrated that LW1564 could limit HIF-1α accumulation and inhibit the proliferation of various cancer cell lines. The drug also inhibited tumor growth in a mouse model of liver cancer.

Abstract
Simple Summary Non-coding RNAs such as microRNAs, long non-coding RNAs, and circular RNAs contribute to the development and progression of hepatocellular carcinoma through epigenetic association. Long non-coding RNAs and circular RNAs act as competing endogenous RNAs that contain binding sites for miRNAs and thus compete with the miRNAs, which results in promotion of miRNA target gene expression, thereby leading to proliferation and metastasis of hepatocellular carcinoma. Competing endogenous RNAs have the potential to become diagnostic biomarkers and therapeutic targets for treatment of hepatocellular carcinoma. Abstract The three major members of non-coding RNAs (ncRNAs), named microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), play an important role in hepatocellular carcinoma (HCC) development. Recently, the competing endogenous RNA (ceRNA) regulation model described lncRNA/circRNA as a sponge for miRNAs to indirectly regulate miRNA downstream target genes. Accumulating evidence has indicated that ceRNA regulatory networks are associated with biological processes in HCC, including cancer cell growth, epithelial to mesenchymal transition (EMT), metastasis, and chemoresistance. In this review, we summarize recent discoveries, which are specific ceRNA regulatory networks (lncRNA/circRNA-miRNA-mRNA) in HCC and discuss their clinical significance.

Abstract
Epigenetic alterations, such as histone modification, DNA methylation, and miRNA-mediated processes, are critically associated with various mechanisms of proliferation and metastasis in several types of cancer. To overcome the side effects and limited effectiveness of drugs for cancer treatment, there is a continuous need for the identification of more effective drug targets and the execution of mechanism of action (MOA) studies. Recently, epigenetic modifiers have been recognized as important therapeutic targets for hepatocellular carcinoma (HCC) based on their reported abilities to suppress HCC metastasis and proliferation in both in vivo and in vitro studies. Therefore, here, we introduce epigenetic modifiers and alterations related to HCC metastasis and proliferation, and their molecular mechanisms in HCC metastasis. The existing data suggest that the study of epigenetic modifiers is important for the development of specific inhibitors and diagnostic targets for HCC treatment.

Abstract
Background The IDF-11774, a novel clinical candidate for cancer therapy, targets HSP70 and inhibits mitochondrial respiration, resulting in the activation of AMPK and reduction in HIF-1α accumulation. Methods To identify genes that have synthetic lethality to IDF-11774, RNA interference screening was conducted, using pooled lentiviruses expressing a short hairpin RNA library. Results We identified ATP6V0C, encoding the V0 subunit C of lysosomal V-ATPase, knockdown of which induced a synergistic growth-inhibitory effect in HCT116 cells in the presence of IDF-11774. The synthetic lethality of IDF-11774 with ATP6V0C possibly correlates with IDF-11774-mediated autolysosome formation. Notably, the synergistic effect of IDF-11774 and the ATP6V0C inhibitor, bafilomycin A1, depended on the PIK3CA genetic status and Bcl-2 expression, which regulates autolysosome formation and apoptosis. Similarly, in an experiment using conditionally reprogramed cells derived from colorectal cancer patients, synergistic growth inhibition was observed in cells with low Bcl-2 expression. Conclusions Bcl-2 is a biomarker for the synthetic lethal interaction of IDF-11774 with ATP6V0C, which is clinically applicable for the treatment of cancer patients with IDF-11774 or autophagy-inducing anti-cancer drugs.

Abstract
Morpholine- and bis(2-methoxyethyl)amine-substituted 1,3,5-triazine derivatives containing an alkoxy-o-carborane in the 6-position of the triazine ring were successfully synthesized. The molecular structures of the methoxy- and ethoxy-o-carboranyl-1,3,5-triazines were established by X-ray crystallography. In vitro studies showed that the methylene bridged morpholine- and bis(2-methoxyethyl)amine-substituted o-carboranyl-1,3,5-triazines accumulated to high levels in B16 melanoma cells and exhibited higher cytotoxicity than p-boronophenylalanine.

Abstract
Abstract
HIF-1 is associated with poor patient prognosis and therapeutic resistance of cancer. We have developed a novel hypoxia-inducible factor (HIF)-1 inhibitor, IDF-11774, as a clinical candidate for cancer therapy. Under hypoxic condition, IDF-11774 inhibited the accumulation of HIF-1α in vitro and in vivo in colorectal carcinoma HCT116 cells. IDF-11774 suppressed the angiogenesis of cancer cells by reducing the expression of HIF-1 target genes. Moreover, IDF-11774 reduced glucose uptake, leading sensitizing cell growth on low glucose condition. IDF-11774 also decreased the extracellular acidification rate (ECAR) and oxygen consumption rate (OCR). Metabolic profile of IDF-11774-treated cells revealed low levels of NAD+, lactate, and intermediates in glycolysis and tricarboxylic acid (TCA) cycle. More importantly, we observed elevated AMP and diminished ATP level, leading high AMP/ATP ratio. Apparently, phosphorylation of AMPK increased, leading inhibition of mTOR signaling in cells. In vivo xenograft assays demonstrated that IDF11774 has significant anti-cancer efficacy by targeting cancer metabolism in mouse models containing the KRAS, PTEN or VHL mutation, which often occurs in many malignant cancers. Collectively, IDF-11774 suppresses the hypoxia-induced HIF-1α accumulation, thereby repressing tumor growth by regulating cancer metabolism.

Abstract
We designed and synthesized strobilurin analogues as hypoxia-inducible factor (HIF) inhibitors based on the molecular structure of kresoxim-methyl. Biological evaluation in human colorectal cancer HCT116 cells showed that most of the synthesized kresoxim-methyl analogues possessed moderate to potent inhibitory activity against hypoxia-induced HIF-1 transcriptional activation. Three candidates, compounds 11b, 11c, and 11d were identified as potent inhibitors against HIF-1 activation with IC50 values of 0.60-0.94µM. Under hypoxic condition, compounds 11b, 11c, and 11d increased the intracellular oxygen contents, thereby attenuating the hypoxia-induced accumulation of HIF-1α protein.

Abstract
The data included in this article are associated with the article entitled “DNA-damage-induced apoptosis suppressor (DDIAS) is upregulated via ERK5/MEF2B signaling and promotes β-catenin-mediated invasion” (J.Y. Im, S.H. Yoon, B.K. Kim, H.S. Ban, K.J. Won, K.S. Chung, K.E. Jung, M. Won) [1]. Quantitative RT-PCR data revealed that genetic or pharmacological inhibition of extracellular signal-regulated kinase 5 (ERK5) suppresses DDIAS transcription in response to epidermal growth factor (EGF) in Hela cells. p300 did not interact with myocyte enhancer factor 2B (MEF2B), a downstream target of ERK5 and affect transcription of DDIAS. Moreover, DDIAS transcription is activated by ERK5/MEF2B signaling on EGF exposure in the non-small cell lung cancer cells (NSCLC) NCI-H1703 and NCI-H1299. DDIAS knockdown suppresses lung cancer cell invasion by decreasing β-catenin protein level on EGF exposure.

Abstract
We previously reported that hypoxia-inducible factor (HIF)-1 inhibitor LW6, an aryloxyacetylamino benzoic acid derivative, inhibits malate dehydrogenase 2 (MDH2) activity during the mitochondrial tricarboxylic acid (TCA) cycle. In this study, we present a novel MDH2 inhibitor compound 7 containing benzohydrazide moiety, which was identified through structure-based virtual screening of chemical library. Similar to LW6, compound 7 inhibited MDH2 activity in a competitive fashion, thereby reducing NADH level. Consequently, compound 7 reduced oxygen consumption and ATP production during the mitochondrial respiration cycle, resulting in increased intracellular oxygen concentration. Therefore, compound 7 suppressed the accumulation of HIF-1α and expression of its target genes, vascular endothelial growth factor (VEGF) and glucose transporter 1 (GLUT1). Moreover, reduction in ATP content activated AMPK, thereby inactivating ACC and mTOR the downstream pathways. As expected, compound 7 exhibited significant growth inhibition of human colorectal cancer HCT116 cells. Compound 7 demonstrated substantial anti-tumor efficacy in an in vivo xenograft assay using HCT116 mouse model. Taken together, a novel MDH2 inhibitor, compound 7, suppressed HIF-1α accumulation via reduction of oxygen consumption and ATP production, integrating metabolism into anti-cancer efficacy in cancer cells.

Abstract
We developed a hypoxia-inducible factor-1 (HIF-1) inhibitor, IDF-11774, as a clinical candidate for cancer therapy. To understand the mechanism of action of IDF-11774, we attempted to isolate target proteins of IDF-11774 using bioconjugated probes. Multifunctional chemical probes containing sites for click conjugation and photoaffinity labeling were designed and synthesized. After fluorescence and photoaffinity labeling of proteins, two-dimensional electrophoresis (2DE) was performed to isolate specific molecular targets of IDF-11774. Heat shock protein (HSP) 70 was identified as a target protein of IDF-11774. We revealed that IDF-11774 inhibited HSP70 chaperone activity by binding to its allosteric pocket, rather than the ATP-binding site in its nucleotide-binding domain (NBD). Moreover, IDF-11774 reduced the oxygen consumption rate (OCR) and ATP production, thereby increasing intracellular oxygen tension. This result suggests that the inhibition of HSP70 chaperone activity by IDF-11774 suppresses HIF-1α refolding and stimulates HIF-1α degradation. Taken together, these findings indicate that IDF-11774-derived chemical probes successfully identified IDF-11774's target molecule, HSP70, and elucidated the mode of action of IDF-11774 in inhibiting HSP70 chaperone activity and stimulating HIF-1α degradation in cancer cells.

Abstract
DNA damage induced apoptosis suppressor (DDIAS) is an anti-apoptotic protein that promotes cancer cell survival. We previously reported that DDIAS is transcriptionally activated by nuclear factor of activated T cells 2 (NFATc1). However, the upstream regulation of DDIAS expression by growth factors has not been studied. Here, we demonstrate that DDIAS expression is induced by extracellular signal-regulated kinase 5 (ERK5) and myocyte enhancer factor 2B (MEF2B) in response to epidermal growth factor (EGF) and that it positively regulates β-catenin signaling in HeLa cells. The genetic or pharmacological inhibition of ERK5 suppressed DDIAS induction following EGF exposure and the overexpression of constitutively active MEK5 (CA-MEK5) enhanced DDIAS expression. In chromatin immunoprecipitation assays, MEF2B, a downstream target of ERK5, exhibited sequence-specific binding to a MEF2 binding site in the DDIAS promoter following treatment with EGF. The overexpression of MEF2B increased the EGF-mediated induction of DDIAS expression, whereas the knockdown of MEF2B impaired this effect. Furthermore, DDIAS promoted invasion by increasing β-catenin expression at the post-translational level in response to EGF, suggesting that DDIAS plays a crucial role in the metastasis of cancer cells by regulating β-catenin expression. It is unlikely that MEF2B and NFATc1 cooperatively regulate DDIAS transcription in response to EGF. Collectively, EGF activates the ERK5/MEF2 pathway, which in turn induces DDIAS expression to promote cancer cell invasion by activating β-catenin target genes.

Abstract
DNA damage induced apoptosis suppressor (DDIAS), or human Noxin (hNoxin), is strongly expressed in lung cancers. DDIAS knockdown induced apoptosis in non-small cell lung carcinoma A549 cells in response to DNA damage, indicating DDIAS as a potential therapeutic target in lung cancer. To understand the transcriptional regulation of DDIAS, we determined the transcription start site, promoter region, and transcription factor. We found that DDIAS transcription begins at nucleotide 212 upstream of the DDIAS translation start site. We cloned the DDIAS promoter region and identified NFAT2 as a major transcription factor (Im et al., 2016 [1]). We demonstrated that NFATc1 regulates DDIAS expression in both pancreatic cancer Panc-1 cells and lung cancer cells.

Abstract
A structure-activity relationship study of hypoxia inducible factor-1α inhibitor 3-aminobenzoic acid-based chemical probes, which were previously identified to bind to mitochondrial malate dehydrogenase 2, was performed to provide a better understanding of the pharmacological effects of LW6 and its relation to hypoxia inducible factor-1α (HIF-1α) and malate dehydrogenase 2 (MDH2). A variety of multifunctional probes including the benzophenone or the trifluoromethyl diazirine for photoaffinity labeling and click reaction were prepared and evaluated for their biological activity using a cell-based HRE-luciferase assay as well as a MDH2 assay in human colorectal cancer HCT116 cells. Among them, the diazirine probe 4a showed strong inhibitory activity against both HIF-1α and MDH2. Significantly, the inhibitory effect of the probes on HIF-1α activity was consistent with that of the MDH2 enzyme assay, which was further confirmed by the effect on in vitro binding activity to recombinant human MDH2, oxygen consumption, ATP production, and AMP activated protein kinase (AMPK) activation. Competitive binding modes of LW6 and probe 4a to MDH2 were also demonstrated.

Abstract
The indenopyrazole framework was investigated as a new class of HIF-1α inhibitors. Indenopyrazole 2l was found to most strongly inhibit the hypoxia-induced HIF-1α transcriptional activity (IC50 = 0.014 μM) among all of the known compounds having relatively simple structures, unlike manassantins. Indenopyrazole 2l suppressed HIF-1α transcriptional activity without affecting both HIF-1α protein accumulation and HIF-1α/HIF-1β heterodimerization in nuclei under the hypoxic conditions, suggesting that 2l probably affected the transcriptional pathway induced by the HIF-1α/HIF-1β heterodimer.

Abstract
Mercaptoundecahydrododecaborate (BSH)-encapsulating 10% distearoyl boron lipid (DSBL) liposomes were developed as a boron delivery vehicle for neutron capture therapy. The current approach is unique because the liposome shell itself possesses cytocidal potential in addition to its encapsulated agents. BSH-encapsulating 10% DSBL liposomes have high boron content (B/P ratio: 2.6) that enables us to prepare liposome solution with 5000 ppm boron concentration. BSH-encapsulating 10% DSBL liposomes displayed excellent boron delivery efficacy to tumor: boron concentrations reached 174, 93, and 32 ppm at doses of 50, 30, and 15 mg B/kg, respectively. Magnescope was also encapsulated in the 10% DSBL liposomes and the real-time biodistribution of the Magnescope-encapsulating DSBL liposomes was measured in a living body using MRI. Significant antitumor effect was observed in mice injected with BSH-encapsulating 10% DSBL liposomes even at the dose of 15 mg B/kg; the tumor completely disappeared three weeks after thermal neutron irradiation ((1.5-1.8) × 10(12) neutrons/cm(2)). The current results enabled us to reduce the total dose of liposomes to less than one-fifth compared with that of the BSH-encapsulating liposomes without reducing the efficacy of boron neutron capture therapy (BNCT).

Abstract
We developed 1-[4-(N-benzylamino)phenyl]-3-phenylurea derivative 4 (GN6958) as a non-peptidic selective SUMO-sentrin specific protease (SENP)1 protease inhibitor based on the hypoxia inducible factor (HIF)-1α inhibitor 1 (GN6767). The direct interaction of compound 1 with SENP1 protein in cells was observed by the pull-down experiments using the biotin-tagged compound 2 coated on the streptavidin affinity column. Among the various 1-[4-(N-benzylamino)phenyl]-3-phenylurea derivatives tested, compounds 3 and 4 suppressed HIF-1α accumulation in a concentration-dependent manner without affecting the expression level of tubulin protein in HeLa cells. Both compounds inhibited SENP1 protease activity in a concentration-dependent manner, and compound 4 exhibited more potent inhibition than compound 3. Compound 4 exhibited selective inhibition against SENP1 protease activity without inhibiting other protease enzyme activities in vitro.

Abstract
The fluorescence-labeled closo-dodecaborane lipid (FL-SBL) was synthesized from (S)-(+)-1,2-isopropylideneglycerol as a chiral starting material. FL-SBL was readily accumulated into the PEGylated DSPC liposomes prepared from DSPC, CH, and DSPE-PEG-OMe by the post insertion protocol. The boron concentrations and the fluorescent intensities of the FL-SBL-labeled DSPC liposomes increased with the increase of the additive FL-SBL, and the maximum emission wavelength of the liposomes appeared at 531 nm. A preliminary in vivo imaging study of tumor-bearing mice revealed that the FL-SBL-labeled DSPC liposomes were delivered to the tumor tissue but not distributed to hypoxic regions.

Abstract
The cell growth inhibition profile of 2,4-(2-methyl-ortho-carboranyl)-4-(dimethylamino)-1,3,5-triazine (TAZ-6) was found to be similar to that of ICRF-193, a topoisomerase II inhibitor, as revealed by COMPARE analysis (correlation coefficient (r) = 0.724). Various mono- and di-ortho-carborane-substituted 1,3,5-triazines were synthesized based on the structure of TAZ-6 and tested for their ability to inhibit cell growth and the activities of topoisomerases I and II. Among the compounds synthesized, 3c, 4c, and 4f completely inhibited topoisomerase I activity without affecting topoisomerase II activity, whereas 3a and 3d completely inhibited topoisomerase II activity without affecting topoisomerase I activity, at 100 μM.

Abstract
The hypoxia-inducible factor (HIF) is a heterodimeric basic helix-loop-helix transcriptional factor and the activated HIF plays pivotal roles in various pathological conditions, including inflammation and cancer. HIF-1alpha overexpression has been observed in many common human cancers, including brain, breast, colon, lung, ovary, and prostate, and HIF-mediated genes, such as vascular endothelial growth factor (VEGF), inducible nitric oxide synthase (iNOS), and insulin-like growth factor (IGF)-1, are associated with tumor angiogenesis, metastasis, and invasion. Therefore, the pro-oncogenic protein HIF is a novel target of cancer therapy. We examined the effects of VEGFR inhibitors, AAL993, SU5416, and KRN633, on suppression of HIF-1alpha accumulation under the hypoxic condition. We found that VEGFR tyrosine kinase inhibitors, AAL993, SU5416, and KRN633, possess dual functions: inhibition of VEGFR signaling and HIF-1alpha expression under the hypoxic condition. The detailed mechanistic study indicated that SU5416 and KRN633 suppressed HIF-1alpha expression through inhibition of both Akt and ERK phosphorylation signaling pathways, whereas AAL993 suppressed HIF-1alpha expression through ERK inhibition without affecting Akt phosphorylation.

Abstract
Closo-dodecaborate lipid liposomes were developed as new vehicles for boron delivery system (BDS) of neutron capture therapy. The current approach is unique because the liposome shell itself possesses cytocidal potential in combination with neutron irradiation. The liposomes composed of closo-dodecaborate lipids DSBL and DPBL displayed high cytotoxicity with thermal neutron irradiation. The closo-dodecaborate lipid liposomes were taken up into the cytoplasm by endocytosis without degradation of the liposomes. Boron concentration of 22.7 ppm in tumor was achieved by injection with DSBL-25% PEG liposomes at 20mg B/kg. Promising BNCT effects were observed in the mice injected with DSBL-25% PEG liposomes: the tumor growth was significantly suppressed after thermal neutron irradiation (1.8 x 10(12)neutrons/cm(2)).

Abstract
A series of boron-containing phenoxyacetanilide derivatives 8a-f, 9a-f, 15, and 16 were synthesized as hypoxia-inducible factor (HIF)-1alpha inhibitors. Among the compounds synthesized, carboranylphenoxyacetanilide 16 (GN26361) was found to be a potent inhibitor against HIF-1alpha accumulation under hypoxic conditions and inhibited the hypoxia-induced HIF-1 transcriptional activity in HeLa cells (IC50=0.74 microM). Compound 16 suppressed hypoxia-induced HIF-1alpha accumulation and vascular endothelial growth factor mRNA expression in a concentration-dependent manner without affecting the expression of HIF-1alpha mRNA.
