Pharmaceuticals (Basel) 2024; 17:224. [PMID: 38399439 PMCID: PMC10892132 DOI: 10.3390/ph17020224] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Revised: 02/01/2024] [Accepted: 02/06/2024] [Indexed: 02/25/2024] Open
Abstract
Background: Arnicolide C, which is isolated from Centipeda minima, has excellent antitumor effects. However, the potential impacts and related mechanisms of action of arnicolide C in breast cancer remain unknown. Methods: The viability of breast cancer cells was measured using MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay and colony formation assays. For analysis of apoptosis and the cell cycle, flow cytometry was used. A molecular docking approach was used to explore the possible targets of arnicolide C. Western blot analysis was used to detect changes in the expression of 14-3-3θ and proteins in related pathways after arnicolide C treatment in breast cancer cells. The anti-breast cancer effect of arnicolide C in vivo was evaluated by establishing cell-derived xenograft (CDX) and patient-derived xenograft (PDX) models. Results: Arnicolide C inhibited proliferation, increased apoptosis, and induced G1 arrest. In particular, molecular docking analysis indicated that arnicolide C binds to 14-3-3θ. Arnicolide C reduced 14-3-3θ expression and inhibited its downstream signaling pathways linked to cell proliferation. Similar results were obtained in the CDX and PDX models. Conclusion: Arnicolide C can have an anti-breast cancer effect both in vitro and in vivo and can induce cell cycle arrest and increase apoptosis in vitro. The molecular mechanism may be related to the effect of arnicolide C on the expression level of 14-3-3θ. However, the specific mechanism through which arnicolide C affects 14-3-3θ protein expression still needs to be determined.

Zhan X, Liu X, Zhang S, Chen H. Expression and prognosis of inducible T-cell co-stimulator and its ligand in Chinese stage I-III lung adenocarcinoma patients. Animal Model Exp Med 2023; 6:464-473.

Abstract
BACKGROUND Immunotherapy has become the fastest-adopting treatment paradigm for lung cancer with improved survival. By binding with its ligand (inducible T-cell co-stimulator and its ligand [ICOSL]), an inducible T-cell co-stimulator (ICOS) could contribute to reversing immunosuppression and improving immune response and thus be a potential target for cancer immunotherapy. METHODS We selected 54 formalin-fixed, paraffin-embedded tumor tissues from cases with stage I-III lung adenocarcinoma cancer. Immunohistochemical expression of ICOS and ICOSL was evaluated. The correlation with clinical parameters in Chinese patients was also compared with TCGA results. RESULTS The positive rates of ICOS and ICOSL were 68% and 81.5%, respectively, in lung tumor tissues. Of these, 9 cases had a low expression of ICOS, and 22 cases had a high expression of ICOS; ICOSL expression was low in 20 cases and high in 24 cases. According to the International Association for the Study of Lung Cancer (8th edition), phase I lesions were detected in 21 cases, phase II lesions in 15 cases, and phase III lesions in 18 cases. The median survival time of all patients was 44.5 months, and the median disease-free survival was 32 months. Univariate analysis showed that the factors significantly associated with overall survival were tumor size, regional lymph node involvement, stage, and expression level of ICOS/ICOSL. Survival analysis using log-rank test indicated that the lower ICOS+ cell infiltration may predict poor prognosis, whereas lower ICOSL protein expression may be associated with better prognosis, but ICOSL data need further validation in larger samples due to inconsistency in TCGA mRNA prediction. CONCLUSION ICOS/ICOSL might be associated with prognosis of lung cancer, and ICOS and its ligand may be potential therapeutic targets in non-small cell lung cancer.

Abstract
This study attempted to determine the expression of p21-activated kinase 4 (PAK4) in non-small cell lung cancer (NSCLC) tissues and the normal lung tissues. The correlation between PAK4 expression and prognosis of NSCLC patients was also evaluated in the present study. The expression level of PAK4 was measured by high-performance liquid chromatography method. Chi-square test was adopted to explore the relationship of PAK4 expression and clinical features. Kaplan-Meier survival curves were plotted to delineate the overall survival rate of NSCLC patients. Cox regression analysis was performed to evaluate the prognostic significance of PAK4 expression in NSCLC. The PAK4 expression in NSCLC tissue samples was significantly higher than that in normal lung tissues (P<0.001) and shared significant correlation with Eastern Cooperative Oncology Group score, histological type, and distant metastasis (P<0.05). Survival curve revealed that NSCLC patients with high PAK4 expression had relatively higher mortality than those with low PAK4 expression (P = .001). Cox regression analysis explained that PAK4 expression was associated with the prognosis of NSCLC patients (P = .024; HR, 3.104; 95% CI, 1.164-8.278). In a word, PAK4 was highly expressed in NSCLC tissues and could act as a prognostic factor for NSCLC patients.

Overexpression of 14-3-3ζ primes disease recurrence, metastasis and resistance to chemotherapy by inducing epithelial-mesenchymal transition in NSCLC. Aging (Albany NY) 2022; 14:5838-5854. [PMID: 35876652 PMCID: PMC9365555 DOI: 10.18632/aging.204188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Accepted: 07/08/2022] [Indexed: 11/25/2022]
Abstract
The prognosis of non-small cell lung cancer (NSCLC) is disappointing because disease recurrence and distant metastasis inevitably occurred. The aim of the present study is to identify novel biomarkers predicting tumor recurrence and metastasis. The 14-3-3ζ protein has been extensively described as a tumor promoter in a panel of solid tumors, including NSCLC. However, there is a big gap regarding the knowledge between 14-3-3ζ and NSCLC recurrence. In this study, we found that overexpression of 14-3-3ζ was more frequent in NSCLC tumor tissues with tumor recurrence. By using scratch healing assay and transwell assay, we demonstrated that NSCLC cells with high expression of 14-3-3ζ gained increased motile and invasive capacity, whereas siRNA-mediated knockdown of endogenous 14-3-3ζ abrogated cancer cell dissemination. Intriguingly, we found that NSCLC cells underwent epithelial-mesenchymal transition (EMT) after the induction of 14-3-3ζ in vitro and in vivo. These findings could be readily recaptured in clinical setting since we showed that NSCLC tumor specimen with high expression of 14-3-3ζ revealed biological features of EMT. Overexpression of 14-3-3ζ also enhanced the phosphorylation of Akt and promoted the proliferation of NSCLC cell lines. In agreement with this notion, we reported that NSCLC cells with high expression of 14-3-3ζ became resistant to chemotherapy-induced apoptosis. These findings strongly suggested that 14-3-3ζ as a novel biomarker predicting risks of disease recurrence and screening 14-3-3ζ status may be a promising approach to select patients who experienced high risks of cancer recurrence and resistance to chemotherapy.

Abstract
Lung adenocarcinoma (LUAD) is one of the leading causes of cancer-related death worldwide. 14-3-3ơ is an intracellular phosphoserine-binding protein that has been proposed to be involved in tumorigenesis. However, the biofunctional role of 14-3-3ơ and its clinicopathological/prognostic significance in LUAD have remained elusive. In the present study, western blot and immunohistochemical analyses of cancer tissues/cells and the corresponding normal controls were performed to verify that 14-3-3ơ was upregulated in LUAD. Univariate and multivariate logistic regression analysis indicated that high expression of 14-3-3ơ predicted poor overall survival and progression-free survival of patients with LUAD. Furthermore, in vivo and in vitro experiments demonstrated that overexpression of 14-3-3ơ markedly promoted cell proliferation, colony formation, anchorage-independent growth and tumor growth, whereas 14-3-3ơ depletion produced the opposite effects. Of note, 14-3-3ơ was identified as an independent prognostic factor for patients with LUAD. Collectively, the present results revealed that high expression of 14-3-3ơ may serve as an independent biomarker, contributing to poor prognosis and progression of LUAD.

Abstract
Lung adenocarcinoma (LUAD) is the most common form of lung cancer and with the highest mortality rate. Therefore, the identification and development of effective methods for the treatment of LUAD is of great importance. The present study aimed to investigate the role of thioredoxin domain-containing protein 9 (TXNDC9) and tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein γ (YWHAG; also known as 14-3-3γ) in the progression of LUAD. The expression of TXNDC9 and its association with the survival of patients with LUAD was analyzed using Encyclopedia of RNA Interactomes. Reverse transcription-quantitative PCR and western blot analysis were used to detect TXNDC9 mRNA and protein expression levels, respectively, in in vitro studies. To investigate the role of TXNDC9 in the progression of LUAD, TXNDC9 was silenced using small interfering RNA transfection. Furthermore, the viability, proliferation, migration, invasiveness and apoptosis of TXNDC9-silenced A549 cells were detected using Cell Counting Kit (CCK)-8, colony formation, wound healing, Transwell and TUNEL assays, respectively. The association between TXNDC9 and YWHAG was analyzed using STRING and Gene Expression Profiling Interactive Analysis databases, as well as co-immunoprecipitation assays. Subsequently, YWHAG was overexpressed to similarly determine effects of YWHAG on viability, proliferation, migration, invasiveness and apoptosis of A549 cells. TXNDC9 expression was markedly upregulated in lung cancer cells, particularly A549 cells, and silencing of TXNDC9 expression suppressed the viability of the lung cancer cells. The results also revealed that TXNDC9 silencing exerted inhibitory effects on the viability, proliferation, migration and invasiveness of A549 cells, whereas the apoptotic rate was increased. Similar to TXNDC9, YWHAG expression was also upregulated in the A549 cells. Furthermore, TXNDC9 was demonstrated to bind to YWHAG and was positively associated with YWHAG. YWHAG overexpression reversed the inhibitory effects of TXNDC9 silencing on LUAD, as evidenced by increased viability, proliferation, migration and invasiveness, and decreased apoptosis, of A549 cells. The present study demonstrated that the knockdown of TXNDC9 exerted suppressive effects on LUAD, whereas YWHAG overexpression reversed the inhibitory effects of TXNDC9 silencing on LUAD. Therefore, TXNDC9 silencing may exert protective effects against LUAD by targeting YWHAG.

Abstract
The 14-3-3 family proteins are vital scaffold proteins that ubiquitously expressed in various tissues. They interact with numerous protein targets and mediate many cellular signaling pathways. The 14-3-3 binding motifs are often embedded in intrinsically disordered regions which are closely associated with liquid-liquid phase separation (LLPS). In the past ten years, LLPS has been observed for a variety of proteins and biological processes, indicating that LLPS plays a fundamental role in the formation of membraneless organelles and cellular condensates. While extensive investigations have been performed on 14-3-3 proteins, its involvement in LLPS is overlooked. To date, 14-3-3 proteins have not been reported to undergo LLPS alone or regulate LLPS of their binding partners. To reveal the potential involvement of 14-3-3 proteins in LLPS, in this review, we summarized the LLPS propensity of 14-3-3 binding partners and found that about one half of them may undergo LLPS spontaneously. We further analyzed the phase separation behavior of representative 14-3-3 binders and discussed how 14-3-3 proteins may be involved. By modulating the conformation and valence of interactions and recruiting other molecules, we speculate that 14-3-3 proteins can efficiently regulate the functions of their targets in the context of LLPS. Considering the critical roles of 14-3-3 proteins, there is an urgent need for investigating the involvement of 14-3-3 proteins in the phase separation process of their targets and the underling mechanisms.

Abstract
Background Non-small cell lung cancer (NSCLC) was usually associated with poor prognosis and invalid therapeutical response to immunotherapy due to biological heterogeneity. It is urgent to screen reliable biomarkers, especially immunotherapy-associated biomarkers, that can predict outcomes of these patients. Methods Gene expression profiles of 1026 NSCLC patients were collected from The Cancer Genome Atlas (TCGA) datasets with their corresponding clinical and somatic mutation data. Based on immune infiltration scores, molecular clustering classification was performed to identify immune subtypes in NSCLC. After the functional enrichment analysis of subtypes, hub genes were further screened using univariate Cox, Lasso, and multivariate Cox regression analysis, and the risk score was defined to construct the prognostic model. Other microarray data and corresponding clinical information of 603 NSCLC patients from the GEO datasets were applied to conduct random forest models for the prognosis of NSCLC with 100 runs of cross-validation. Finally, external datasets with immunotherapy and chemotherapy were further applied to explore the significance of risk-scores in clinical immunotherapy response for NSCLC patients. Results Compared with Subtype-B, the Subtype-A, associated with better outcomes, was characterized by significantly higher stromal and immune scores, T lymphocytes infiltration scores and up-regulation of immunotherapy markers. In addition, we found and validated an eleven -gene signatures for better application of distinguishing high- and low-risk NSCLC patients and predict patients’ prognosis and therapeutical response to immunotherapy. Furthermore, combined with other clinical characteristics based on multivariate Cox regression analysis, we successfully constructed and validated a nomogram to effectively predict the survival rate of NSCLC patients. External immunotherapy and chemotherapy cohorts validated the patients with higher risk-scores exhibited significant therapeutic response and clinical benefits. Conclusion These results demonstrated the immunological and prognostic heterogeneity within NSCLC and provided a new clinical application in predicting the prognosis and benefits of immunotherapy for the disease.

Abstract
Long non-coding RNAs (lncRNAs) have been found to play regulatory roles in cancers; for example, UCC was reported to promote colorectal cancer progression. However, the function of UCC in non-small-cell lung cancer (NSCLC) remains unclear. Therefore, mRNA and protein levels were assessed using qPCR and western blots. Cell viability was assessed by colony-formation assays. The interaction between lncRNAs and miRNAs was detected by dual-luciferase reporter and RIP assays. The tumorigenesis of NSCLC cells in vivo was determined by xenograft assays. LncRNA UCC was highly expressed in both NSCLC tissues and cells. Knockdown of UCC expression suppressed the proliferation of NSCLC cells. In addition, a dual-luciferase reporter system and RIP assays showed that UCC specifically bound to miR-143-3p and acted as a sponge of miR-143-3p in NSCLC cells. The miR-143-3p inhibitor rescued the inhibitory effect of sh-UCC on the proliferation of NSCLC cells. Moreover, miR-143-3p and UCC showed opposite effects on the expression of SOX5, which promoted EMT in NSCLC cells. In addition, in a mouse model, knockdown of UCC expression alleviated EMT and NSCLC progression in vivo, which was consistent with the in vitro results. In the current study, we found that UCC induced the proliferation and migration of NSCLC cells both in vitro and in vivo by inducing the expression of SOX5 via miR-143-3p and subsequently promoted EMT in NSCLC.

Abstract
The aim of the study is to investigate how lncRNA EWSAT1 regulates the tumorigenesis of non-small cell lung cancer (NSCLC) as a ceRNA by modulating miR-330-5p/ITGA5 axis. qRT-PCR was conducted to evaluate the expression of EWSAT1 in NSCLC tissue. Then, A549 cells were selected and divided into Blank shScramble, shEWSAT1, miR-330-5p inhibitor, shEWSAT1 + miR-330-5p inhibitor, and siITGA5 and miR-330-5p inhibitor + siITGA5 groups. Besides, a series of in-vitro experiments were carried out to determine the changes in cell proliferation, apoptosis, invasion, and migration in each group. In addition, xenograft models were also constructed on nude mice to detect the tumor volume and weight, and the expression of Ki67 and apoptosis in xenograft tumor were evaluated. In NSCLC tissue and cell, EWSAT1 was upregulated significantly, demonstrating a correlation with tumor diameter, differentiation, lymph node metastasis, and TNM stage. Dual luciferase reporter gene assay confirmed targeting relationships among miR-330-5p, EWSAT1, and ITGA5. In comparison with the Blank group, the number of cell clones in the shEWSAT1 group and siITGA5 decreased, with declined invasion and migration but increased apoptotic rate. Meanwhile, ITGA5, MMP-2, and MMP-9 were downregulated with upregulated cleaved caspase-3. However, the changes above were totally reversed in the miR-330-5p inhibitor group, and miR-330-5p inhibitor transfection abolished the effect of shEWSAT1. In addition, subcutaneous xenotransplantation showed that the tumor growth in shEWSAT1 group retarded significantly, with downregulation of Ki67 and increase apoptotic rate. Silencing EWSAT1 could inhibit the expression of ITGA5 via upregulating miR-330-5p, thus, resulting in the inhibition of NSCLC cell growth.

Abstract
Recent advances in genomics unraveled several actionable mutational drivers in lung cancer, leading to promising therapies such as tyrosine kinase inhibitors and immune checkpoint inhibitors. However, the tumors' acquired resistance to the newly-developed as well as existing therapies restricts life quality improvements. Therefore, we investigated the noncoding portion of the human transcriptome in search of alternative actionable targets. We identified an antisense transcript, LY6K-AS, with elevated expression in lung adenocarcinoma (LUAD) patients, and its higher expression in LUAD patients predicts poor survival outcomes. LY6K-AS abrogation interfered with the mitotic progression of lung cancer cells resulting in unfaithful chromosomal segregation. LY6K-AS interacts with and stabilizes 14-3-3 proteins to regulate the transcription of kinetochore and mitotic checkpoint proteins. We also show that LY6K-AS regulates the levels of histone H3 lysine 4 trimethylation (H3K4me3) at the promoters of kinetochore members. Cisplatin treatment and LY6K-AS silencing affect many common pathways enriched in cell cycle-related functions. LY6K-AS silencing affects the growth of xenografts derived from wildtype and cisplatin-resistant lung cancer cells. Collectively, these data indicate that LY6K-AS silencing is a promising therapeutic option for LUAD that inhibits oncogenic mitotic progression.

Abstract
Cancer progression is dependent on heightened mechanical adaptation, both for the cells' ability to change shape and to interact with varying mechanical environments. This type of adaptation is dependent on mechanoresponsive proteins that sense and respond to mechanical stress, as well as their regulators. Mechanoresponsive proteins are part of the mechanobiome, which is the larger network that constitutes the cell's mechanical systems that are also highly integrated with many other cellular systems, such as gene expression, metabolism, and signaling. Despite the altered expression patterns of key mechanobiome proteins across many different cancer types, pharmaceutical targeting of these proteins has been overlooked. Here, we review the biochemistry of key mechanoresponsive proteins, specifically nonmuscle myosin II, α-actinins, and filamins, as well as the partnering proteins 14-3-3 and CLP36. We also examined a wide range of data sets to assess how gene and protein expression levels of these proteins are altered across many different cancer types. Finally, we determined the potential of targeting these proteins to mitigate invasion or metastasis and suggest that the mechanobiome is a goldmine of opportunity for anticancer drug discovery and development.

Abstract
At present, cancers have been causing deadly fears to humans and previously unpredictable
losses to health. Especially, lung cancer is one of the most common causes of cancer-related mortality
accounting for approximately 15% of all cancer cases worldwide. While Non-Small Cell Lung Carcinomas
(NSCLCs) makes up to 80% of lung cancer cases. The patient compliance has been weakening
because of serious drug resistance and adverse drug effects. Therefore, there is an urgent need for the
development of novel structural agents to inhibit NSCLCs. Nitrogen-containing heterocyclic compounds
exhibit wide range of biological properties, especially antitumor activity. We reviewed some
deadly defects of clinical medicines for the lung cancer therapy and importance of nitrogen based heterocyclic
derivatives against NSCLCs. Nitrogen heterocycles exhibit significant antitumor activity
against NSCLCs. Nitrogen heterocyclic hybrids could be developed as multi-target-directed NSCLC
inhibitors and it is believed that the review is significant for rational designs and new ideas in the development
of nitrogen heterocyclic-based drugs.

Abstract
14-3-3 proteins are a family of conserved regulatory adaptor molecules which are expressed in all eukaryotic cells. These proteins participate in a variety of intracellular processes by recognizing specific phosphorylation motifs and interacting with hundreds of target proteins. Also, 14-3-3 proteins act as molecular chaperones, preventing the aggregation of unfolded proteins under conditions of cellular stress. Furthermore, 14-3-3 proteins have been shown to have similar expression patterns in tumors, aging, and neurodegenerative diseases. Therefore, we put forward the idea that the adaptor activity and chaperone-like activity of 14-3-3 proteins might play a substantial role in the above-mentioned conditions. Interestingly, 14-3-3 proteins are considered to be standing at the crossroads of cancer, aging, and age-related neurodegenerative diseases. There are great possibilities to improve the above-mentioned diseases and conditions through intervention in the activity of the 14-3-3 protein family.

Abstract
Protein-protein interactions (PPIs) mediate a variety of cellular processes and form complex networks, where connectivity is achieved owing to the "hub" proteins whose interaction with multiple protein partners is facilitated by the intrinsically disordered protein regions (IDPRs) and posttranslational modifications (PTMs). Universal regulatory proteins of the eukaryotic 14-3-3 family nicely exemplify these concepts and are the focus of this chapter. The extremely wide interactome of 14-3-3 proteins is characterized by high levels of intrinsic disorder (ID) enabling protein phosphorylation and consequent specific binding to the well-structured 14-3-3 dimers, one of the first phosphoserine/phosphothreonine binding modules discovered. However, high ID enrichment also challenges structural studies, thereby limiting the progress in the development of small molecule modulators of the key 14-3-3 PPIs of increased medical importance. Besides the well-known structural flexibility of their variable C-terminal tails, recent studies revealed the strong and conserved ID propensity hidden in the N-terminal segment of 14-3-3 proteins (~40 residues), normally forming the α-helical dimerization region, that may have a potential role for the dimer/monomer dynamics and recently reported moonlighting chaperone-like activity of these proteins. We review the role of ID in the 14-3-3 structure, their interactome, and also in selected 14-3-3 complexes. In addition, we discuss approaches that, in the future, may help minimize the disproportion between the large amount of known 14-3-3 partners and the small number of 14-3-3 complexes characterized with atomic precision, to unleash the whole potential of 14-3-3 PPIs as drug targets.

Abstract
PURPOSE Pseudopodia are actin-rich ventral protrusions associated with cell motility and cancer cell invasion. We previously applied our established method of using excimer laser cell etching to isolate pseudopodial proteins from MDA-MB-231 breast cancer cells. We later identified 14-3-3γ as an oncogenic molecule among 46 candidate proteins that are specific to pseudopodia. The present study aimed to determine the function of 14-3-3γ in the motility of breast cancer cells. METHODS MDA-MB-231 cells were cultured on 3-µm porous membranes and double stained to localize 14-3-3γ and phalloidin in pseudopodia using confocal imaging. We assessed pseudopodia numbers and length, as well as migration and wound healing in MDA-MB-231 cells with knockdown and forced expression of 14-3-3γ to determine 14-3-3γ involvement in cell motility. We also immunohistochemically analyzed 14-3-3γ in human breast cancer tissues with high-grade lymphatic invasion. RESULTS We specifically located 14-3-3γ in pseudopodia of MDA-MB-231 cells. Knockdown and forced expression of 14-3-3γ, respectively, decreased and increased pseudopodial formation and elongation. Migration and wound healing assays also showed that 14-3-3γ knockdown and forced expression, respectively, decreased and increased the number of underside cells and acellular areas in MDA-MB-231 breast cancer cells. More 14-3-3γ was expressed in sites of lymphatic invasion, than in the center and periphery of human breast cancer tissues. CONCLUSION The role of 14-3-3γ in breast cancer invasiveness might be to promote cell motility. Inhibition of 14-3-3γ could, therefore, become a novel target of therapy to prevent invasion and metastasis in patients with breast cancers expressing 14-3-3γ.

Abstract
Although numerous dysregulated circular RNAs (circRNAs) was discovered, the study between circRNAs and non-small cell lung cancer (NSCLC) is just beginning. Here, we investigated the functions and provided a possible mechanism of circ_0000735 for NSCLC. Real-time PCR was used to elucidate the level of circ_0000735 in NSCLC tissue samples and cells. CCK8, colony formation, flow cytometric, and transwell experiments were carried out to evaluate cell proliferation, apoptosis, migratory and invasive abilities in NSCLC cell lines. Luciferase reporter assays were conducted to elucidate the mechanisms of circ_0000735 in NSCLC. Circ_0000735 was elevated in both NSCLC tissues and cells. This upregulation of circ_0000735 is associated with more advanced TNM stages and lymph node invasion. Gain and loss of function experiments documented that circ_0000735 significantly facilitated cell proliferation, migratory and invasive abilities and inhibit cell apoptosis. Moreover, we proved circ_0000735 could bound to miR-1179/1182 to exert its biological functions in NSCLC cells. Taken together, this work provided a possible treatment target for this devastating disease.

Abstract
Long noncoding RNAs are capable of regulating gene expression at multiple levels. These RNA molecules are also involved in a variety of physiological and pathological processes. Emerging data demonstrate that a series of differentially expressed long noncoding RNAs are implicated in tumorigenesis. In the present study, we used microarray analysis to identify long noncoding RNAs that are dysregulated in non-small-cell lung cancer when compared to normal lung tissues. Accordingly, we performed quantitative real-time polymerase chain reaction to analyze the levels of long noncoding RNA and the cis target gene. We further found the oncogene property of long noncoding RNA that long noncoding RNA downexpression inhibits non-small-cell lung cancer cells proliferation and migration based on 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide and colony formation assays and wound healing as well as transwell assays. The influence of long noncoding RNA on cell cycle of non-small-cell lung cancer cells is also analyzed by flow cytometry. Among the dysregulated long noncoding RNAs, we identified INS-IGF2 readthrough, transcript variant 1, noncoding RNA (NR_003512.3) is upregulated in non-small-cell lung cancer tissues, the cis gene of which is insulin-like growth factor 2 gene hinted by bioinformatics analysis. We also observed that downregulation of INS-IGF2 readthrough, transcript variant 1, noncoding RNA reduces insulin-like growth factor 2 messenger RNA expression. Furthermore, INS-IGF2 readthrough, transcript variant 1, noncoding RNA downregulation suppresses non-small-cell lung cancer cell proliferation and migration. This downregulation results in a concomitant inhibition of the G1/S transition in non-small-cell lung cancer cells. Our findings suggest that INS-IGF2 readthrough, transcript variant 1, noncoding RNA may be an oncogene involved in the development of lung cancer. Therefore, we speculate that INS-IGF2 readthrough, transcript variant 1, noncoding RNA represents a potential therapeutic target for lung cancer.

Abstract
Long noncoding RNAs (lncRNAs), with length of more than 200 nucleotides, are not translated into proteins but involved in multiple diverse diseases, especially tumorigenesis. The dysregulation of lncRNAs greatly contributes to the progression of various tumors through specific signaling pathways, including Wnt/β-catenin signaling pathway, which is associated with malignant features of tumors. The interactions between lncRNAs, which have specific expression characteristics in diverse cancer tissues, and Wnt/β-catenin signaling pathway, exhibit potential as novel biomarkers and therapeutic targets. In this review, we aim to present research findings on the roles of Wnt pathway-related lncRNAs and their effects on Wnt/β-catenin signaling to regulate tumorigenesis in different cancer types. Results may be used as basis to develop or improve strategies for treatment of different carcinomas.

Abstract
Previous studies have suggested that circular RNAs (circRNAs) serve crucial functions in various human diseases, including cancer. The results of the present study demonstrated that the expression levels of circ-0067934 were significantly increased in non-small cell lung cancer (NSCLC) tissues and NSCLC cells compared with that in adjacent normal tissues and a normal human bronchial epithelium cell line, as assessed using reverse transcription-quantitative polymerase chain reaction. Increased expression levels of circ-0067934 were associated with lymph node metastasis and advanced tumor stage in patients with NSCLC. Increased levels of circ-0067934 were significantly associated with the poor overall survival (OS) time of patients with NSCLC compared with low circ-0067934 expression levels, as assessed using Kaplan-Meier estimator survival curves and log-rank tests. Additionally, circ-0067934 was identified as an independent risk factor for OS time in patients with NSCLC, as assessed using univariate and multivariate Cox proportional hazards regression models. Additionally, cell proliferation and colony formation assays were employed to assess cell proliferation. The results demonstrated that the proliferative ability was significantly inhibited when circ-0067934 was knocked down in NSCLC cells. Therefore, these results indicated that circ-0067934 may be a predictive marker for the prognosis of NSCLC and a target for the treatment of the disease.

Abstract
Accumulating evidence documented the key functions of circular RNAs (circRNAs) in various malignancies. However, the study regarding the involvement of circRNAs in non-small cell lung cancer (NSCLC) has just begun. In the present study, qRT-PCR was used to determine the expression of circ_0001649 in NSCLC tissues and cells. Its clinical significance was further assessed by Fisher's exact test, Kaplan-Meier analysis and Cox regression model. Additionally, loss-of-function and gain-of-function experiments were carried out to detect the functional role of circ_0001649 in cell proliferation, migration and invasion. Furthermore, animal study was performed to confirm the in vitro results. Importantly, luciferase reporter assay was induced to reveal the underlying mechanism of circ_0001649. As a result, circ_0001649 was decreased in NSCLC tissues and cells and this downregulation is correlated with advanced TNM stage, positive lymph node metastasis and unfavorable prognosis. Additionally, circ_0001649 inhibited cell growth and metastasis both in vitro and in vivo. In mechanism, circ_0001649 was identified as the sponge of miR-331-3p and miR-338-5p. Moreover, the biological functions of circ_0001649 is partly dependent on its regulation on miR-331-3p and miR-338-5p. Collectively, this study suggested that circ_0001649/miR-331-3p/miR-338-5p regulatory signaling might be a potential target for NSCLC therapy.

Extracellular vesicles with altered tetraspanin CD9 and CD151 levels confer increased prostate cell motility and invasion. Sci Rep 2018; 8:8822. [PMID: 29891991 PMCID: PMC5995928 DOI: 10.1038/s41598-018-27180-z] [Citation(s) in RCA: 45] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2017] [Accepted: 05/25/2018] [Indexed: 02/06/2023] Open
Abstract
To facilitate intercellular communication, cells release nano-sized, extracellular vesicles (EVs) to transfer biological cargo to both local and distant sites. EVs are enriched in tetraspanins, two of which (CD9 and CD151) have altered expression patterns in many solid tumours, including prostate cancer, as they advance toward metastasis. We aimed to determine whether EVs from prostate cells with altered CD9 and CD151 expression could influence cellular behaviour and increase the metastatic capabilities of non-tumourigenic prostate cells. EVs were isolated by ultrafiltration and characterised for their tetraspanin expression and size distribution. iTRAQ was used to identify differences between RWPE1 and tetraspanin-modified RWPE1 EV proteomes, showing an enrichment in protein degradation pathways. Addition of EVs from RWPE1 cells with reduced CD9 or increased CD151 abundance resulted in increased invasion of RWPE1 cells, and increased migration in the case of high CD151 abundance. We have been able to show that alteration of CD9 and CD151 on prostate cells alters the proteome of their resultant EVs, and that these EVs can enhance the migratory and invasive capabilities of a non-tumourigenic prostate cellular population. This work suggests that cellular tetraspanin levels can alter EVs, potentially acting as a driver of metastasis in prostate cancer.

Abstract
Long noncoding RNA (lncRNA) has been indicated to have an important role in various types of malignant tumors; however, only a small number of lncRNAs have been entirely elucidated. In the present study, a novel lncRNA, actin filament associated protein 1 antisense RNA 1 (AFAP1-AS1), was investigated, which is highly expressed in non-small cell lung cancer (NSCLC). Reverse transcription-quantitative polymerase chain reaction and in situ hybridization were performed to detect AFAP1-AS1 expression in frozen tissues and tissue microarrays, respectively. The results revealed that the expression level of AFAP1-AS1 was significantly increased in tumor tissues, compared with the paired non-cancerous tissues. It was also determined that the AFAP1-AS1 expression level was higher in patients with lymph node metastasis than those without lymph node metastasis (P=0.014). Kaplan-Meier analysis was conducted to evaluate the overall survival of patients with NSCLC and different expression levels of AFAP1-AS1, and the results indicated that patients with high AFAP1-AS1 expression had a reduced survival time, compared with those with low AFAP1-AS1 expression (P=0.011). Cox regression analysis was also performed to analyze the prognostic value of lncRNA AFAP1-AS1. The obtained data demonstrated that lncRNA AFAP1-AS1 was an unfavorable prognostic biomarker for NSCLC (HR: 3.12, 95% CI (1.05–9.25), P=0.040). In conclusion, it was demonstrated that lncRNA AFAP1-AS1 is overexpressed in NSCLC and an unfavorable biomarker for patients with NSCLC.

Abstract
Diffuse large B cell lymphoma (DLBCL) patients with early relapse or refractory disease have a very poor outcome. Immunochemotherapy resistance will probably, also in the era of targeted drugs, remain the major cause of treatment failure. We used proteomic mass spectrometry to analyse the global protein expression of micro-dissected formalin-fixed paraffin-embedded tumour tissues from 97 DLBCL patients: 44 with primary refractory disease or relapse within 1 year from diagnosis (REF/REL), and 53 who were progression-free more than 5 years after diagnosis (CURED). We identified 2127 proteins: 442 were found in all patients and 102 were differentially expressed. Sixty-five proteins were overexpressed in REF/REL patients, of which 46 were ribosomal proteins (RPs) compared with 2 of the 37 overexpressed proteins in CURED patients (P = 7·6 × 10-10 ). Twenty of 37 overexpressed proteins in CURED patients were associated with actin regulation, compared with 1 of 65 in REF/REL patients (P = 1·4 × 10-9 ). Immunohistochemical staining showed higher expression of RPS5 and RPL17 in REF/REL patients while MARCKS-like protein, belonging to the actin network, was more highly expressed in CURED patients. Even though functional studies aimed at individual proteins and protein interactions to evaluate potential clinical effect are needed, our findings suggest new mechanisms behind immunochemotherapy resistance in DLBCL.

Abstract
Antisense RNA (AS) is a type of long non-coding RNAs that functions as a post-transcriptional regulatory element on regulating parental coding gene expression via directly binding to complementary mRNA sequences. We aimed to investigate the effect of the AS to FEZF1 gene on non-small cell lung cancer (NSCLC) development. The expression level of lncRNA FEZF-AS1 and FEZF1 was determined by the quantitative Real-time PCR in 160 cases of NSCLC tissues and their adjacent non-tumour tissues. We found that lncRNA FEZF-AS1 was significantly up-regulated in tumour tissues when compared to the adjacent non-cancerous tissues (P = 0.001), and it's high expression correlated with advanced stages (P = 0.002) and Tumour Family History (P = 0.029). Meanwhile, In 58 cases of NSCLC tissues the expression of lncRNA FEZF-AS1 was positively associated with that of FEZF1expression (r = 0.8810, p = 1.6575E-20). By GEPIA database analysis, we also found that the expression of lncRNA FEZF-AS1 and FEZF1 were significantly higher in tumour tissues than those of the adjacent non-cancerous tissues in 969 NSCLC patients (P < 0.05), and lncRNA FEZF-AS1 was positively correlated with FEZF1 (r = 0.90, P < 0.001). These results suggest that lncRNA FEZF-AS1 relate to the progression of lung cancer patients and it may be a potential target for cancer therapy.

Abstract
Protein 14-3-3γ was significantly reduced in human uterine leiomyoma compared to the adjacent normal myometrium tissue. To investigate the possible link between the reduced 14-3-3γ expression and uterine leiomyoma growth, we have overexpressed 14-3-3γ protein in uterine leiomyomal cells and its effects on cell proliferation and apoptosis were analyzed. Over-expression of 14-3-3γ was achieved by transducing into two types of uterine leiomyoma cells (primary culture cells and immortal stem cells) with a 14-3-3γ expressing adenovirus vector. Differentially expressed proteins were screened by the proteomics tool (TMT-LCTMS), followed by PANTHER database analysis to single out specifically modified signaling pathway proteins, which were confirmed by Phospho-MAPK Antibody Array and Western blots analysis. The results showed that increase in 14-3-3γ expression in both two types of human uterine leiomyoma cells inhibited cell proliferation and induced apoptosis. Proteomic screening has found 42 proteins, among 5846, that were significantly affected. PANTHER database and GeneMANIA analysis of the differentially expressed proteins have found that proteins involved in apoptosis signaling and cytoskeletal/adhesion were among the ones affected the most. Further analysis of the key signaling pathways have found that over-expression of 14-3-3γ resulted in reductions in the phosphorylations of multiple signaling molecules, including AKT, pan, ERK1/2, GSK-3 α/β, MEK1/2, Foxo1 and Vimentin. In conclusion, the loss of 14-3-3γ may have causal effects on the growth of uterine leiomyoma, which may function through modifying multiple signaling pathways, including AKT-Foxo and/or MEK1/2-ERK1/2.

Abstract
Several studies have demonstrated that specific 14-3-3 isoforms are frequently elevated in cancer and that these proteins play a role in human tumorigenesis. 14-3-3γ, an isoform recently demonstrated to function as an oncoprotein, is overexpressed in a variety of human cancers; however, its role in promoting tumorigenesis remains unclear. We previously reported that overexpression of 14-3-3γ caused the appearance of polyploid cells, a phenotype demonstrated to have profound tumor promoting properties. Here we examined the mechanism driving 14-3-3γ-induced polyploidization and the effect this has on genomic stability. Using FUCCI probes we showed that these polyploid cells appeared when diploid cells failed to enter mitosis and subsequently underwent endoreduplication. We then demonstrated that 14-3-3γ-induced polyploid cells experience significant chromosomal segregation errors during mitosis and observed that some of these cells stably propagate as tetraploids when isolated cells were expanded into stable cultures. These data lead us to conclude that overexpression of the 14-3-3γ promotes endoreduplication. We further investigated the role of 14-3-3γ in human NSCLC samples and found that its expression is significantly elevated in polyploid tumors. Collectively, these results suggests that 14-3-3γ may promote tumorigenesis through the production of a genetically unstable polyploid intermediate.

Abstract
Accumulating evidence demonstrates that a series of differentially expressed lncRNAs is important in tumorigenesis. However, the function of many of the lncRNAs in lung cancer remains elusive. In the present study, we used microarray analysis to identify lncRNAs that are dysregulated in non-small-cell lung cancer (NSCLC) as compared with normal tissues. Among the dysregulated lncRNAs, we identified TFPI2AS1, an antisense transcript of the tumor suppressor TFPI2 (tissue factor pathway inhibitor 2). TFPI2AS1 was shown to be markedly upregulated in NSCLC patient tumors as compared to paired non-tumor samples. TFPI2AS1 knockdown increased NSCLC cell proliferation and migration, which was associated with enhanced G1/S transition and downregulation of cyclin D1 and cyclin-dependent kinases 2 (CDK2), while TFPI2AS1 overexpression had the opposite effect. Knockdown and overexpression experiments also suggested that TFPI2AS1 regulates NSCLC cell migration and AKT activation. Moreover, TFPI2AS1 is a positive regulator of TFPI2. Our findings bring new insights for understanding the role of TFPI2AS1 in mediating the proliferation and migration of NSCLC cells by regulating TFPI2 expression.

Wang R, Yan B, Li Z, Jiang Y, Mao C, Wang X, Zhou X. Long non-coding RNA HOX transcript antisense RNA promotes expression of 14-3-3σ in non-small cell lung cancer. Exp Ther Med 2017; 14:4503-4508. [PMID: 29067125 DOI: 10.3892/etm.2017.5041] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2015] [Accepted: 03/10/2017] [Indexed: 12/21/2022] Open
Abstract
Evidence suggests that both 14-3-3σ and long non-coding RNA HOX transcript antisense RNA (HOTAIR) are involved in the tumorigenesis and progression of lung cancer. In the present study, the potential association between 14-3-3σ and HOTAIR in non-small cell lung cancer (NSCLC) was investigated. In tissue samples collected from 54 patients with NSCLC, expression of HOTAIR and 14-3-3σ was analyzed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). After stable ectopic expression of HOTAIR and stable HOTAIR knockdown in PC9 cancer cells, the effect of HOTAIR on levels of mRNA and protein 14-3-3σ expression levels were detected using RT-qPCR and western blotting, respectively. Expression of HOTAIR and 14-3-3σ in NSCLC tissues was significantly higher than in adjacent non-cancerous lung tissue (P<0.05). Correlation analysis also identified a correlation between levels of HOTAIR and 14-3-3σ expression in NSCLC tissues (r=0.725, P=0.0005). In addition, overexpression and knockdown of HOTAIR in the human NSCLC cell line PC9 led to the upregulation and downregulation of 14-3-3σ, respectively, at both the mRNA and protein levels (all P<0.05). To the best of our knowledge, the present study provides the first in vivo and in vitro evidence to suggest that HOTAIR promotes the expression of 14-3-3σ in NSCLC. The potential association between HOTAIR and 14-3-3σ indicates that both biomolecules may be viable targets in anticancer therapy.

Abstract
The 14-3-3 family proteins are phosphoserine/phosphothreonine binding proteins constituting a conserved class of proteins which are detected in all eukaryotic cells. In mammalians, 14-3-3 proteins have seven distinct isoforms (β, γ, ε, η, ζ, σ and τ/θ) which are involved in various cellular processes including signal transduction, cell cycle, cell proliferation, apoptosis, differentiation and survival. 14-3-3 proteins do not have a distinct catalytic activity and often regulate the activity, stability, subcellular localization and interactions of other proteins. The 14-3-3 family proteins function through interacting with their client proteins or facilitating the interaction of other proteins likely as adaptor proteins. The versatile functions of these proteins in the regulation of cell growth, cell division, cell death and cell migration make them candidate proteins for which an important role in cancer development could be envisioned. Indeed, analysis of cancer cell lines and tumor-derived tissues have indicated the differential abundance or post-translational modification of some 14-3-3 isoforms. In this review, we aimed to show how deregulation of 14-3-3 proteins contributes to initiation, establishment and progression of cancers with a particular emphasis on lung cancer. The role of these proteins in cancer-relevant processes including cell cycle, cell migration, cell-cell communication and programmed cell death will be discussed in detail.

Abstract
The treatment of advanced or refractory non-small cell lung cancer has been historically difficult owing to the lack of studies on effective systemic cure. The progress in lung cancer treatment has plateaued, necessitating new options for additional benefits. Immune checkpoint proteins are co-inhibitory factors that can diminish the antigen-specific immune responses by attenuating the regulatory role of cytotoxic T-lymphocyte-associated protein 4, programmed cell death-1, lymphocyte-activation gene 3, and T-cell immunoglobulin mucin-3. The therapeutic strategies targeting immune checkpoints mainly focus on the monoclonal antibody of these regulatory factors, which may facilitate clinical decision making. An enhanced understanding of the drug-resistance mechanisms and the therapeutic efficacy regulation will provide opportunities to improve the clinical outcomes of non-small cell lung cancer patients. Preclinical and clinical trials on these key immune-regulatory agents, which has heralded a new era in immuno-oncology in non-small cell lung cancer treatment, are currently in development.

The KDM5 family is required for activation of pro-proliferative cell cycle genes during adipocyte differentiation. Nucleic Acids Res 2017; 45:1743-1759.

Abstract
The KDM5 family of histone demethylases removes the H3K4 tri-methylation (H3K4me3) mark frequently found at promoter regions of actively transcribed genes and is therefore generally considered to contribute to corepression. In this study, we show that knockdown (KD) of all expressed members of the KDM5 family in white and brown preadipocytes leads to deregulated gene expression and blocks differentiation to mature adipocytes. KDM5 KD leads to a considerable increase in H3K4me3 at promoter regions; however, these changes in H3K4me3 have a limited effect on gene expression per se. By contrast, genome-wide analyses demonstrate that KDM5A is strongly enriched at KDM5-activated promoters, which generally have high levels of H3K4me3 and are associated with highly expressed genes. We show that KDM5-activated genes include a large set of cell cycle regulators and that the KDM5s are necessary for mitotic clonal expansion in 3T3-L1 cells, indicating that KDM5 KD may interfere with differentiation in part by impairing proliferation. Notably, the demethylase activity of KDM5A is required for activation of at least a subset of pro-proliferative cell cycle genes. In conclusion, the KDM5 family acts as dual modulators of gene expression in preadipocytes and is required for early stage differentiation and activation of pro-proliferative cell cycle genes.

Abstract
AIM CHIP (c-terminal Hsp70-interacting protein) is an E3 ligase playing vital roles in various cancers. The VEGF pathway has become an important therapeutic target in non-small cell lung cancer (NSCLC). However, little is known about the role of CHIP and the relationship between CHIP and VEGF-VEGFR2 (VEGF receptor 2) pathway in NSCLC. In this study we aimed to investigate the clinical function of CHIP in NSCLC and explore the relevant regulatory mechanism. METHODS QRT-PCR was performed to detect CHIP expression in NSCLC tissues. The association of CHIP expression and clinical parameters was analyzed using the Chi-square test. Kaplan- Meier and Cox analyses were performed to identify the role of CHIP in the prognosis of NSCLC patients. ELISA test was used to detect the VEGF secretion of NSCLC cells and western blot were used to detected the protein expression of VEGFR2 in NSCLC cells. RESULTS and the results revealed that CHIP expression was decreased in NSCLC tissues and significantly correlated with clinical stages, lymph node metastasis and distant metastasis (P<0.05). Moreover, Kaplan-Meier and Cox regression analyses showed that patients with negative expression of CHIP had a shorter survival time and CHIP could be an independent prognostic biomarker. In addition, ELISA tests showed that CHIP negatively regulated the secretion level of VEGF. Furthermore, western blot assay indicated that the VEGFR2 protein level was reduced after CHIP over-expression. CONCLUSIONS Taken together, our findings demonstrate for the first time that CHIP may serve as a promising prognostic biomarker for NSCLC patients and it may be involved in NSCLC angiogenesis through regulating VEGF secretion and expression of VEGFR2.

Abstract
Background Recent studies indicate that long noncoding RNAs (lncRNAs) play a key role in the control of cellular processes such as proliferation, metastasis, and differentiation. The lncRNA dysregulation has been identified in all types of cancer. We previously found that lncRNA AK126698 suppresses cisplatin resistance in A549 cells through the Wnt/β-catenin signaling pathway. However, the clinical significance of lncRNA AK126698 and the molecular mechanisms through which it regulates cancer cell proliferation and migration are largely unknown. Methods We examined the expression of lncRNA AK126698 in 56 non-small cell lung cancer (NSCLC) tissue samples and three NSCLC cell lines using quantitative real-time polymerase chain reaction. Gain and loss of function approaches were used to evaluate the biological function of AK126698 in NSCLC cells. The effects of lncRNA AK126698 on cell proliferation were investigated using cell counting kit-8 and 5-ethynyl-2′-deoxyuridine assays, and apoptosis was measured by flow cytometry. Protein levels of AK126698 targets were evaluated by Western blotting. Results Our results showed that lncRNA AK126698 was significantly downregulated in NSCLC tissues, compared with paired adjacent nontumor tissue samples. Furthermore, lower AK126698 expression was associated with larger tumor size and advanced tumor stage. Ectopic AK126698 expression inhibited cell proliferation and migration and induced apoptosis. Conversely, decreased AK126698 expression promoted cell proliferation and migration and inhibited cell apoptosis. Importantly, we demonstrated that Frizzled-8, a receptor of Wnt/β-catenin pathway, was a target of AK126698. Furthermore, AK126698 could inhibit the activation of Wnt/β-catenin pathway, which was demonstrated by measuring the expression levels of Axin1, β-catenin, c-myc, cyclin D1, and E-cadherin. Conclusion It was found in the study that lncRNA AK126698 inhibits the proliferation and migration of NSCLC cells by targeting Frizzled-8 to suppress the Wnt/β-catenin signaling pathway. It may provide a new target for therapeutic intervention in NSCLC.

Abstract
Anoctamin-1 (ANO1) acts as a Ca2+-activated Cl− channel in various normal tissues, and its expression is increased in several different types of cancer. Therefore, understanding the regulation of ANO1 surface expression is important for determining its physiological and pathophysiological functions. However, the trafficking mechanism of ANO1 remains elusive. Here, we report that segment a (N-terminal 116 amino acids) of ANO1 is crucial for its surface expression, and we identified 14-3-3γ as a binding partner for anterograde trafficking using yeast two-hybrid screening. The surface expression of ANO1 was enhanced by 14-3-3γ, and the Thr9 residue of ANO1 was critical for its interaction with 14-3-3γ. Gene silencing of 14-3-3γ and/or ANO1 demonstrated that suppression of ANO1 surface expression inhibited migration and invasion of glioblastoma cells. These findings provide novel therapeutic implications for glioblastomas, which are associated with poor prognosis.

Abstract
The 14-3-3 protein family is among the most extensively studied, yet still largely mysterious protein families in mammals to date. As they are well recognized for their roles in apoptosis, cell cycle regulation, and proliferation in healthy cells, aberrant 14-3-3 expression has unsurprisingly emerged as instrumental in the development of many cancers and in prognosis. Interestingly, while the seven known 14-3-3 isoforms in humans have many similar functions across cell types, evidence of isoform-specific functions and localization has been observed in both healthy and diseased cells. The strikingly high similarity among 14-3-3 isoforms has made it difficult to delineate isoform-specific functions and for isoform-specific targeting. Here, we review our knowledge of 14-3-3 interactome(s) generated by high-throughput techniques, bioinformatics, structural genomics and chemical genomics and point out that integrating the information with molecular dynamics (MD) simulations may bring us new opportunity to the design of isoform-specific inhibitors, which can not only be used as powerful research tools for delineating distinct interactomes of individual 14-3-3 isoforms, but also can serve as potential new anti-cancer drugs that selectively target aberrant 14-3-3 isoform.

Abstract
Long non-coding RNA (lncRNA) is actively transcribed from human genome and has been considered to participate in many processes of various cancers. The purpose of this study was to investigate the expression of LncRNA AFAP1-AS1 and its prognostic value in NSCLC. LncRNA AFAP1-AS1 expression was detected by qRT-PCR which demonstrated that the expression was significantly increased in tumor tissues compared with the adjacent non-cancerous tissues and healthy tissues. The clinical stage, smoking history, infiltration degree, lymph node metastasis and distant metastasis were all proved to impact the expression of LncRNA AFAP1-AS1 (P<0.05). Kaplan-Meier analysis was performed to evaluate the overall survival of NSCLC patients with different expression level of LncRNA AFAP1-AS1, and results showed that patients with high LncRNA AFAP1-AS1 expression lived shorter than those with low LncRNA AFAP1-AS1 expression (Log rank test, P<0.001). Besides, the prognostic value of LncRNA AFAP1-AS1 as well as the clinical features was assessed by Cox regression analysis. The outcome revealed that LncRNA AFAP1-AS1 was closely related to the prognosis of NSCLC. Taken together, LncRNA AFAP1-AS1 was up-regulated in NSCLC tissues and it could be an independent prognostic indicator for NSCLC patients.
