Abstract
The M2 isoform of pyruvate kinase (PKM2) is one isoform of pyruvate kinase (PK). PKM2 is expressed at high levels during embryonic development and tumor progression and is subject to complex allosteric regulation. PKM2 is a special glycolytic enzyme that regulates the final step of glycolysis; the role of PKM2 in the metabolism, survival, and apoptosis of cancer cells has received increasing attention. Mitochondria are directly or indirectly involved in the regulation of energy metabolism, susceptibility to oxidative stress, and cell death; however, the role of PKM2 in mitochondrial functions remains unclear. Herein, we review the related mechanisms of the role of PKM2 in the regulation of mitochondrial functions from the aspects of metabolism, reactive oxygen species (ROS), dynamic, and apoptosis, which can be highlighted as a target for the clinical management of cardiovascular and metabolic diseases.

Abstract
Cell surface proteases (also known as ectoproteases) are transmembrane and membrane-bound enzymes involved in various physiological and pathological processes. Several members, most notably dipeptidyl peptidase 4 (DPP4/CD26) and its related family member fibroblast activation protein (FAP), aminopeptidase N (APN/CD13), a disintegrin and metalloprotease 17 (ADAM17/TACE), and matrix metalloproteinases (MMPs) MMP2 and MMP9, are often overexpressed in cancers and have been associated with tumour dysfunction. With multifaceted actions, these ectoproteases have been validated as therapeutic targets for cancer. Numerous inhibitors have been developed to target these enzymes, attempting to control their enzymatic activity. Even though clinical trials with these compounds did not show the expected results in most cases, the field of ectoprotease inhibitors is growing. This review summarizes the current knowledge on this subject and highlights the recent development of more effective and selective drugs targeting ectoproteases among which small molecular weight inhibitors, peptide conjugates, prodrugs, or monoclonal antibodies (mAbs) and derivatives. These promising avenues have the potential to deliver novel therapeutic strategies in the treatment of cancers.

Abstract
Cancer cells usually show adaptations to their metabolism that facilitate their growth, invasiveness, and metastasis. Therefore, reprogramming the energy metabolism is one of the current key foci of cancer research and treatment. Although aerobic glycolysis-the Warburg effect-has been thought to be the dominant energy metabolism in cancer, recent data indicate a different possibility, specifically that oxidative phosphorylation (OXPHOS) is the more likely form of energy metabolism in some cancer cells. Due to the heterogeneity of epithelial ovarian cancer, there are different metabolic preferences among cell types, study types (in vivo/in vitro), and invasiveness. Current knowledge acknowledges glycolysis to be the main energy provider in ovarian cancer growth, invasion, migration, and viability, so specific agents targeting the glycolysis or OXPHOS pathways have been used in previous studies to attenuate tumor progression and increase chemosensitization. However, chemoresistant cell lines exert various metabolic preferences. This review comprehensively summarizes the information from existing reports which could together provide an in-depth understanding and insights for the development of a novel targeted therapy which can be used as an adjunctive treatment to standard chemotherapy to decelerate tumor progression and decrease the epithelial ovarian cancer mortality rate.

Abstract
Ovarian cancer is a common cause of death among gynecological cancers. Although ovarian cancer initially responds to chemotherapy, frequent recurrence in patients remains a therapeutic challenge. Pyruvate kinase M2 (PKM2) plays a pivotal role in regulating cancer cell survival. However, its therapeutic role remains unclear. Here, we investigated the anticancer effects of compound 3K, a specific PKM2 inhibitor, on the regulation of autophagic and apoptotic pathways in SK-OV-3 (PKM2-overexpressing human ovarian adenocarcinoma cell line). The anticancer effect of compound 3K was examined using MTT and colony formation assays in SK-OV-3 cells. PKM2 expression was positively correlated with the severity of the tumor, and expression of pro-apoptotic proteins increased in SK-OV-3 cells following compound 3K treatment. Compound 3K induced AMPK activation, which was accompanied by mTOR inhibition. Additionally, this compound inhibited glycolysis, resulting in reduced proliferation of SK-OV-3 cells. Compound 3K treatment suppressed tumor progression in an in vivo xenograft model. Our findings suggest that the inhibition of PKM2 by compound 3K affected the Warburg effect and induced autophagic cell death. Therefore, use of specific PKM2 inhibitors to block the glycolytic pathway and target cancer cell metabolism represents a promising therapeutic approach for treating PKM2-overexpressing ovarian cancer.

Abstract
Oral tongue squamous cell carcinoma (OTSCC) is a highly malignant type of tumor. The 5-year survival rate of patients with advanced tongue squamous cell carcinoma is only ~50%. Pyruvate kinase M2 (PKM2) is the key rate-limiting enzyme of glycolysis, maintaining the Warburg effect in tumor cells. The present study aimed to investigate the relationship between PKM2 expression and the poor prognosis of patients with OTSCC and to determine oral squamous carcinoma tumor cell proliferation and apoptosis. Reverse transcription-quantitative (RT-q) PCR, western blotting and immunohistochemistry were used to analyze the expression levels of PKM2 in OTSCC, and the clinicopathological characteristics and prognosis of patients with OTSCC were further analyzed by statistical analysis. The results from RT-qPCR and immunohistochemistry demonstrated that PKM2 was upregulated in OTSCC tissues and highly expressed in advanced stage OTSCC tissues compared with paired adjacent tissues and lower stage OTSCC tissues. Patients with OTSCC and high PKM2 expression had shorter overall survival (OS) compared with those with low PKM2 expression. Furthermore, high expression of PKM2 was significantly associated with Tumor-Node-Metastasis (TNM) stage. TNM stage and PKM2 expression were independent predictive factors for OS in patients with OTSCC. In addition, PKM2 knockdown inhibited the proliferation and increased the apoptosis of oral squamous carcinoma tumor cells. Furthermore, PKM2 knockdown could regulate the expression of cell cycle and apoptosis-related proteins by activating Hippo signaling pathway, as confirmed by the decreased expression of yes-associated protein 1 (YAP), Bcl-2 and Ki-67 and the increased expression of large tumor suppressor kinase 1, phosphorylated YAP and Bax. Taken together, the findings from this study demonstrated that PKM2 may be considered as a potential target for the diagnosis and treatment of OTSCC.

Abstract
Gastric carcinoma is a common malignant cancer. Pyruvate kinase M2 (PKM2) is highly expressed in cancers, including gastric carcinoma. However, its function and molecular mechanism in gastric carcinoma remains unclear. Here, we aimed to explore the function and the underlying mechanism of PKM2 on malignant phenotypes in gastric carcinoma. In this study, the mRNA levels and protein levels of PKM2 in gastric carcinoma cell lines and normal gastric mucosa epithelial cell lines were detected using quantitative real-time PCR and western blot, respectively. PKM2 was downregulated by siRNA transfection. HIF-1α or BCL-6 was upregulated by corresponding overexpression plasmid. Cell viability was detected using CCK-8 assay. Cell invasion and migration were determined using transwell assay. Higher expression of PKM2 was observed in human gastric carcinoma cell lines MKN-45 and SGC-7901 than in the normal gastric mucosa epithelial cell line GES-1. PKM2 knockdown suppressed cancer cell invasion and migration and inhibited the epithelial-mesenchymal transition (EMT) phenotype by inhibiting E-cadherin and promoting vimentin and N-cadherin expression. Also, we observed that PKM2 knockdown suppressed the hypoxia-inducible factor alpha (HIF-1α) and B-cell lymphoma 6 (BCL-6) signaling pathway. HIF-1α overexpression reversed the function of PKM2 silencing on cell invasion, migration, EMT, and BCL-6 expression. BCL-6 overexpression also reversed the function of PKM2 silencing on cell invasion, migration, and EMT but did not affect HIF-1α expression. Taken together, data from our study suggest that PKM2 knockdown impeded cell migration, invasion, and EMT of gastric carcinoma cells via the HIF-1α/BCL-6 pathway.

Reprod Biol Endocrinol 2020; 18:58. [PMID: 32493421 PMCID: PMC7268382 DOI: 10.1186/s12958-020-00613-z] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Accepted: 05/17/2020] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disease with unknown pathogenesis. However, the treatment of Diane-35 combined with metformin can improve the endocrine and ovulation of PCOS. In this study, we investigated the effects of Diane-35 combined with metformin (DM) treatment on ovulation and glucose metabolism in a PCOS rat model. METHODS Sprague Dawley rats were divided into 3 groups, control group, model group (PCOS group) and Diane-35 combined with metformin (PCOS + DM group). The mRNA expression levels were determined by qRT-PCR. The hormone levels were determined by enzyme-linked immunosorbent assay. Immunostaining detected the protein levels of lactate dehydrogenase A (LDH-A), pyruvate kinase isozyme M2 (PKM2) and sirtuin 1 (SIRT1) in the ovarian tissues. TNUEL assay was performed to determine cell apoptosis in the PCOS rats. The metabolites in the ovarian tissues were analyzed by liquid chromatography with tandem mass spectrometry. RESULTS PCOS rats showed an increased in body weight, levels of luteinizing hormone and testosterone and insulin resistance, which was significantly attenuated by the DM treatment. The DM treatment improved disrupted estrous cycle and increased the granulosa cells of the ovary in the PCOS rats. The decreased proliferation and increased cell apoptosis of granulosa cells in the ovarian tissues of PCOS rats were significantly reversed by the DM treatment. The analysis of metabolics revealed that ATP and lactate levels were significantly decreased in PCOS rats, which was recovered by the DM treatment. Furthermore, the expression of LDH-A, PKM2 and SIRT1 was significantly down-regulated in ovarian tissues of the PCOS rats; while the DM treatment significantly increased the expression of LDH-A, PKM2 and SIRT1 in the ovarian tissues of the PCOS rats. CONCLUSION In conclusion, our study demonstrated that Diane-35 plus metformin treatment improved the pathological changes in the PCOS rats. Further studies suggest that Diane-35 plus metformin can improve the energy metabolism of the ovary via regulating the glycolysis pathway. The mechanistic studies indicated that the therapeutic effects of Diane-35 plus metformin treatment in the PCOS rats may be associated with the regulation of glycolysis-related mediators including PKM2, LDH-A and SIRT1.

Abstract
FA-SAT is a highly conserved satellite DNA sequence transcribed in many Bilateria species. To disclose the cellular and functional profile of FA-SAT non-coding RNAs, a comprehensive experimental approach, including the transcripts location in the cell and in the cell cycle, the identification of its putative protein interactors, and silencing/ectopic expression phenotype analysis, was performed. FA-SAT non-coding RNAs play a nuclear function at the G1 phase of the cell cycle and the interactomic assay showed that the PKM2 protein is the main interactor. The disruption of the FA-SAT non-coding RNA/PKM2 protein complex, by the depletion of either FA-SAT or PKM2, results in the same phenotype-apoptosis, and the ectopic overexpression of FA-SAT did not affect the cell-cycle progression, but promotes the PKM2 nuclear accumulation. Overall, our data first describe the importance of this ribonucleoprotein complex in apoptosis and cell-cycle progression, what foresees a promising novel candidate molecular target for cancer therapy and diagnosis.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) has poor survival and treatment options. PDAC cells shift their metabolism towards glycolysis, which fuels the plasma membrane calcium pump (PMCA), thereby preventing Ca2+-dependent cell death. The ATP-generating pyruvate kinase-M2 (PKM2) is oncogenic and overexpressed in PDAC. This study investigated the PKM2-derived ATP supply to the PMCA as a potential therapeutic locus. METHODS PDAC cell growth, migration and death were assessed by using sulforhodamine-B/tetrazolium-based assays, gap closure assay and poly-ADP ribose polymerase (PARP1) cleavage, respectively. Cellular ATP and metabolism were assessed using luciferase/fluorescent-based assays and the Seahorse XFe96 analyzer, respectively. Cell surface biotinylation identified membrane-associated proteins. Fura-2 imaging was used to assess cytosolic Ca2+ overload and in situ Ca2+ clearance. PKM2 knockdown was achieved using siRNA. RESULTS The PKM2 inhibitor (shikonin) reduced PDAC cell proliferation, cell migration and induced cell death. This was due to inhibition of glycolysis, ATP depletion, inhibition of PMCA and cytotoxic Ca2+ overload. PKM2 associates with plasma membrane proteins providing a privileged ATP supply to the PMCA. PKM2 knockdown reduced PMCA activity and reduced the sensitivity of shikonin-induced cell death. CONCLUSIONS Cutting off the PKM2-derived ATP supply to the PMCA represents a novel therapeutic strategy for the treatment of PDAC.

Abstract
Background Previous studies have suggested that the functions of prolyl hydroxylase 3 (PHD3) in tumor growth, apoptosis and angiogenesis are essentially dependent on hypoxia-inducible factor (HIF)-1α signaling. Nevertheless, whether PHD3 represents a promising tumor suppressor target remains to be clarified. To provide insight into the therapeutic potential of PHD3 in lung cancer, this study examined the effects of PHD3 expression on HIF-1α and pyruvate kinase M2 (PKM2), as well as on lung cancer cell proliferation, migration, and invasion. Methods The model of hypoxia was established in A549 and SK-MES-1 cells with 200 µM CoCl2 treatment, and verified by western blot and immunocytochemical staining. The expression levels of PKM2 and HIF-1α were determined by western blot after overexpression or depletion of PHD3 in A549 and SK-MES-1 cells. In addition, cell viability, migration and invasion were measured, respectively. Results Establishment of hypoxia in A549 and SK-MES-1 cells resulted in significant decreases in PHD3 expression and remarkable increase in PKM2 expression in 24 hrs. Overexpression of PHD3 in A549 and SK-MES-1 cells decreased HIF-1α and PKM2 expression. In contrast, PHD3 knockdown increased HIF-1α and PKM2 (P<0.05). In addition, the viability, migration and invasion of A549 and SK-MES-1 cells were significantly decreased with PHD3 overexpression, but dramatically increased with PHD3 depletion (P<0.05). Conclusions PHD3 is involved in lung cancer progression, and might be a promising therapeutic target for cancers.

Abstract
PURPOSE Reprogramming of cell metabolism is essential for tumor progression and the best-studied metabolic phenomenon of cancer cells is aerobic glycolysis, in which pyruvate kinase isozyme type M2 (PKM2) plays a critical role. Follicle-stimulating hormone (FSH) contributes to epithelial ovarian cancer progression and has been shown to regulate cell metabolism in ovaries. The aim of this study was to investigate the interaction between FSH and PKM2 and their effect on aerobic glycolysis and cell proliferation in ovarian cancer. METHODS SKOV3 and OVCAR3 ovarian cancer cells were treated with FSH at various doses to investigate its effect on cell proliferation and PKM2 expression. siRNA-PKM2-transfected SKOV3 and OVCAR3 cells were treated with FSH to examine whether the changes induced by FSH could be altered by siRNA-PKM2. Glucose and lactate levels were evaluated to observe the change in glycolysis in these cells. RESULTS In the current study, FSH upregulated the expression of PKM2 and glycolysis in SKOV3 and OVCAR3 cells. PKM2 knockdown reduced FSH-induced cell growth and glycolysis. Moreover, FSH attenuated apoptosis that was induced by the inhibition of PKM2. CONCLUSIONS Collectively, the findings of this study indicated that FSH promoted glycolysis in epithelial ovarian cancer cells. Knockdown of PKM2 inhibited aerobic glycolysis and cell proliferation induced by FSH.

Abstract
Cancer cells preferentially use aerobic glycolysis over mitochondria oxidative phosphorylation for energy production, and this metabolic reprogramming is currently recognized as a hallmark of cancer. Oncogenic signaling frequently converges with this metabolic shift, increasing cancer cells' ability to produce building blocks and energy, as well as to maintain redox homeostasis. Alterations in cell-cell and cell-extracellular matrix (ECM) adhesion promote cancer cell invasion, intravasation, anchorage-independent survival in circulation, and extravasation, as well as homing in a distant organ. Importantly, during this multi-step metastatic process, cells need to induce metabolic rewiring, in order to produce the energy needed, as well as to impair oxidative stress. Although the individual implications of adhesion molecules and metabolic reprogramming in cancer have been widely explored over the years, the crosstalk between cell adhesion molecular machinery and metabolic pathways is far from being clearly understood, in both normal and cancer contexts. This review summarizes our understanding about the influence of cell-cell and cell-matrix adhesion in the metabolic behavior of cancer cells, with a special focus concerning the role of classical cadherins, such as Epithelial (E)-cadherin and Placental (P)-cadherin.

Abstract
Human papillomaviruses (HPVs) have important roles in the development and progression of cervical cancer, but the underlying mechanisms are yet to be fully elucidated. MicroRNA-130a (miR-130a) has previously been reported to promote cervical cancer growth. However, the underlying molecular mechanisms by which miR-130a promotes cervical cancer progression have remained largely elusive. In the present study, polymerase chain reaction and western blot analyses were performed to examine the expression levels of miR-130a and associated proteins. A wound healing assay and a Transwell assay were applied to study cell migration and invasion. A luciferase reporter gene assay was performed to confirm the targeting associations of miR-130a. It was observed that miR-130a was significantly upregulated in cervical cancer tissues compared with that in adjacent non-tumorous tissues. High expression of miR-130a was significantly associated with lymph node metastasis and an advanced clinical stage of cervical cancer. Furthermore, the expression of miR-130a was also higher in HPV(+) cervical cancer cell lines compared with that in HPV(-) cells. Knockdown of HPV18 E6 significantly inhibited the expression of miR-130a in HeLa cervical cancer cells. Furthermore, knockdown of miR-130a reduced the migration and invasion of HeLa cells. Tissue inhibitor of metalloproteinase 2 (TIMP2), an antagonist of matrix metalloproteinase 2 (MMP2), was identified as a novel, direct target gene of miR-130a. The expression of TIMP2 was negatively mediated by miR-130a, and HPV18 E6 inhibited the expression of TIMP2 in HeLa cells. Furthermore, knockdown of TIMP2 rescued the suppressive effects of miR-130a downregulation on the migration and invasion of HeLa cells. In summary, the present study suggests that HPV18 E6 promotes the expression of miR-130a, which further inhibits the expression of TIMP2 and promotes cervical cancer cell invasion. Therefore, HPV/miR-130a/TIMP2 signaling may be a potential target for the prevention of cervical cancer metastasis.

Abstract
Glioblastoma is the most common and malignant primary brain tumor. RWD domain containing 3 (RWDD3) has been previously reported to serve a promoting role in pituitary tumors. However, the exact role of RWDD3 in glioblastoma remains unclear. Therefore, the present study aimed to investigate the expression levels of RWDD3 in human glioblastoma tissues and cell lines, as well as to examine the regulatory mechanism of RWDD3 underlying glioblastoma growth and metastasis. The results revealed that RWDD3 was significantly upregulated in glioblastoma tissues compared with normal brain tissues, while high expression of RWDD3 was associated with a shorter survival time of glioblastoma patients. The expression levels of RWDD3 were also higher in the glioblastoma cell lines compared with the normal human astrocyte cell line. Subsequent to knockdown of RWDD3, the proliferation of glioblastoma U87 and U251 cells was significantly decreased, possibly due to the cell cycle arrest at G1 phase, as well as the increased cell apoptosis. Furthermore, downregulation of RWDD3 also suppressed U87 and U251 cell invasion by inhibiting the expression levels of matrix metalloproteinase 2 (MMP2) and MMP9. Molecular mechanism investigation demonstrated that knockdown of RWDD3 significantly downregulated the activity of the phosphoinositide 3-kinase/protein kinase B (PI3K/AKT) signaling pathway. Activation of PI3K/AKT signaling prevented the suppressive effects of RWDD3 downregulation on glioblastoma cell proliferation and migration, concurrent with increased protein levels of MMP2 and MMP9. In conclusion, the current study demonstrated for the first time that inhibition of RWDD3 expression inhibited glioblastoma progression, at least partly, via suppressing the PI3K/AKT signaling activity, and thus RWDD3 may be a novel potential therapeutic target for glioblastoma.

Abstract
Multiple studies have shown that protein kinase Bβ (AKT2) is involved in the development and progression of ovarian cancer, however, its precise role remains unclear. Here we explored the underlying molecular mechanisms how AKT2 promotes ovarian cancer progression. We examined the effects of AKT2 in vitro in two ovarian cancer cell lines (SKOV3 and HEY), and in vivo by metastasis assay in nude mice. The migration and invasion ability of SKOV3 and HEY cells was determined by transwell assay. Overexpression and knockdown (with shRNA) experiments were carried out to unravel the underlying signaling mechanisms induced by AKT2. Overexpression of AKT2 led to increased expression of pyruvate kinase (PKM2) in ovarian cancer cells and in lung metastatic foci from nude mice. Elevated AKT2/PKM2 expression induced cell migration and invasion in vitro, as well as lung metastasis in vivo; silencing AKT2 blocked these effects. Meanwhile, PKM2 overexpression was unable to increase AKT2 expression. The expressions of p-PI3K, p-AKT2, and PKM2 were increased when stimulated by epidermal growth factor (EGF); however, these expressions were blocked when inhibited the PI3K by LY294002. STAT3 expression was elevated and NF-κB p65 nuclear translocation was activated both in vitro and in vivo when either AKT2 or PKM2 was overexpressed; and these effects were inhibited when silencing AKT2 expression. Taken together, AKT2 increases the migration and invasion of ovarian cancer cells in vitro and promotes lung metastasis in nude mice in vivo through PKM2-mediated elevation of STAT3 expression and NF-κB activation. In conclusion, we highlight a novel mechanism of the AKT2-PKM2-STAT3/NF-κB axis in the regulation of ovarian cancer progression, and our work suggested that both AKT2 and PKM2 may be potential targets for the treatment of ovarian cancer.

Abstract
MicroRNAs (miRs) serve promoting or suppressive roles in various human cancer types, including ovarian cancer; however, the role of miR-142-3p in ovarian cancer growth and chemoresistance has not previously been studied. In the present study, reverse transcription-quantitative polymerase chain reaction and western blotting were used to examine miR and protein expression levels. An MTT assay was used to examine cell proliferation. A luciferase reporter gene assay was used to clarify the target gene of miR-142-3p. The present study reported that miR-142-3p expression levels were significantly lower in ovarian cancer tissues and cell lines, when compared with those in adjacent tissues and the normal human ovarian epithelial cell line IOSE386, respectively. The reduced expression of miR-142-3p was significantly associated with poor cell differentiation. Ectopic expression of miR-142-3p significantly inhibited the proliferation of ovarian cancer cells and increased the sensitivity of SKOV3/DDP cells to cisplatin. Sirtuin 1 (SIRT1) was identified as a target gene of miR-142-3p; SIRT1 expression was negatively regulated by miR-142-3p in ovarian cancer cells. Further investigation demonstrated that SIRT1 reversed the suppressive effects of miR-142-3p on the proliferation and chemoresistance of ovarian cancer cells. In addition, SIRT1 was significantly upregulated in ovarian cancer. A negative correlation between the expression of SIRT1 and miR-142-3p in ovarian cancer tissues was also observed. In summary, the present study indicated that miR-142-3p inhibits the proliferation and chemoresistance of ovarian cancer cells by targeting SIRT1. This suggests that miR-142-3p may be a promising therapeutic candidate for the treatment of ovarian cancer.

Abstract
The aim of the present study was to investigate the effects of microRNA (miR)-183 on vitality, invasion, metastasis and apoptosis in osteosarcoma (OS) cells, mediated by its binding to metastasis-associated protein 1 (MTA1). A dual luciferase reporter assay was performed to determine whether MTA1 was a direct target of miR-183. Cell Counting Kit-8, Transwell, scratch-wound healing, fluorescence-activated cell sorting andterminal deoxynucleotidyl transferase dUTP nick end labeling assays were also performed to investigate the effects of miR-183 expression on the proliferation, invasion, migration and apoptosis of MG63 cells. It was demonstrated that that MTA1 expression levels were significantly higher in OS tissues and MG63 cells compared with corresponding adjacent noncancerous tissues and normal cells, respectively, while miR-183 expression levels were significantly lower (both P<0.05). Furthermore, miR-183 overexpression downregulated MTA1 levels and inhibited cell proliferation (P<0.05), migration (P<0.05) and invasion (P<0.01), as well as promoting apoptosis (P<0.01) by binding to the 3'-untranslated region of MTA1. These results indicate that miR-183 inhibits the vitality, invasion, migration and apoptosis of the OS cell line MG63 by targeting MTA1. These findings may contribute to the development of novel clinical therapeutic approaches for the treatment of OS.

Abstract
LncRNA urothelial carcinoma associated 1 (UCA1) was reported to be upregulated in non-small cell lung cancer (NSCLC) tissues and contributed to NSCLC progression. Additionally, it has been proposed that the oncogenic role of UCA1 may be related to glucose metabolism in bladder cancer. However, whether and how UCA1 regulates glucose metabolism in the progression of NSCLC remains unknown. Our results showed that knockdown of UCA1 inhibited the viability of NSCLC cells. UCA1 silencing suppressed glycolysis of NSCLC cells by reducing the glucose consumption and lactate production. Additionally, knockdown of UCA1 suppressed PKM2 expression and the mTOR pathway in NSCLC cells. Mechanistically, PKM2 knockdown suppressed the effects of UCA1 on viability and glycolysis of NSCLC cells and inhibition of the mTOR pathway suppressed the effects of UCA1 on viability, glycolysis, and PKM2 expression in NSCLC cells. In conclusion, knockdown of UCA1 inhibited viability and glycolysis by suppressing PKM2 expression maybe through the mTOR pathway in NSCLC cells, providing a novel insight into the molecular mechanism of UCA1 involved in the regulation of glucose metabolism in NSCLC cells.

Abstract
This study aims to explore the effects of shRNA-mediated silencing on Pyruvate kinase type M2 (PKM2) gene during aerobic glycolysis in colorectal cancer (CRC) cells. CRC tissues and adjacent normal tissues were obtained from 136 patients diagnosed with qRT-PCR, Western blotting, and immunohistochemistry (IHC) were performed to detect mRNA and protein expressions of PKM2. CRC cells were divided into a blank, vector, and PKM2-shRNA groups. Hexokinase (HK) and PKM2 activity were both determined by glucose-6-phosphate dehydrogenase (G-6-PD) coupled colorimetric assay and enzyme coupling rate method. The extracellular lactate concentration was measured by ultraviolet spectrophotometer and caspase activity was measured using spectrophotometry. The proliferation, cell cycle, apoptosis, invasion, and migration of CRC cells were detected by cell counting kit-8 (CCK-8) assay, flow cytometry, transwell assay, and scratch test. Three groups of nude mice were injected with 0.2 mL single-cell suspension from the blank, vector, and PKM2-shRNA groups, respectively. PKM2 protein content in CRC tissues was higher than that in adjacent normal tissues. Results showed that the PKM2-shRNA group exhibited significantly lower mRNA and protein expressions of PKM2, decreased PKM2 activity, reduced lactate metabolism level, increased cell apoptosis rate, elevated caspase-3 and caspase-9 activity, weakened proliferation, and a reduction in cell invasion and migration ability compared to the vector and blank groups. The optical density (OD) value was lower in the PKM2-shRNA group than in the blank and vector groups. These findings indicate that shRNA-mediated silencing of PKM2 gene promotes apoptosis and inhibits aerobic glycolysis, proliferation, migration, and invasion in CRC cells. J. Cell.

Eur J Med Chem 2017; 138:343-352. [PMID: 28688274 DOI: 10.1016/j.ejmech.2017.06.064] [Citation(s) in RCA: 61] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2017] [Revised: 06/27/2017] [Accepted: 06/28/2017] [Indexed: 11/28/2022]
Abstract
Pyruvate kinase M2 (PKM2) is a rate-limiting enzyme of the glycolytic pathway which is highly expressed in cancer cells. Cancer cells rely heavily on PKM2 for anabolic and energy requirements, and specific targeting of PKM2 therefore has potential as strategy for cancer therapy. Here, we report the synthesis and biologic evaluation of novel naphthoquinone derivatives as selective small molecule inhibitors of PKM2. Some target compounds, such as compound 3k, displayed more potent PKM2 inhibitory activity than the reported optimal PKM2 inhibitor shikonin. The well performing compound 3k also showed nanomolar antiproliferative activity toward a series of cancer cell lines with high expression of PKM2 including HCT116, Hela and H1299 with IC50 values ranging from 0.18 to 1.56 μM. Moreover, compound 3k exhibited more cytotoxicity on cancer cells than normal cells. The identification of novel potent small molecule inhibitors of PKM2 not only offers candidate compounds for cancer therapy, but also provides a tool with which to evaluate the function of PKM2 in depth.
