Int J Mol Sci 2022; 23:13181. [PMID: 36361971 PMCID: PMC9655098 DOI: 10.3390/ijms232113181] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 10/26/2022] [Accepted: 10/26/2022] [Indexed: 07/30/2023] Open
Abstract
Quinoline derivatives have been reported to possess a wide range of pharmaceutical activities. Our group previously synthesized a series of quinoline compounds, in which compound 91b1 showed a significant anticancer effect. The purpose of this study was to evaluate the anticancer activity of compound 91b1 in vitro and in vivo, and screen out its regulated target. A series of cancer cell lines and nontumor cell lines were treated with compound 91b1 by MTS cytotoxicity assay and cell-cycle assay. In vivo anticancer activity was evaluated by a xenografted model on nude mice. Target prediction of 91b1 was assessed by microarray assay and confirmed by pancancer analysis. Relative expression of the target gene Lumican was measured by qRT-PCR. 91b1 significantly reduced tumor size in the nude mice xenograft model. Lumican was downregulated after 91b1 treatment. Lumican was proven to increase tumorigenesis in vivo, as well as cancer cell migration, invasion, and proliferation in vitro. The results of this study suggest that the anticancer activity of compound 91b1 probably works through downregulating the gene Lumican.

Abstract
BACKGROUND Calpains (CAPNs) are intracellular calcium-activated neutral cysteine proteinases involved in cancer initiation, progression, and metastasis. However, its role in pancreatic cancer (PC) is still unclear. This study aims to identify the prognostic value and immune infiltration of CAPNs for PC patients using comprehensive bioinformatics analyzes. METHODS We analyzed the transcription levels of CAPNs in different cancers from Oncomine, differential gene expression in tumor/normal tissues and pathological stage through GEPIA database, the prognostic value of the mRNA expression of CAPNs by Kaplan-Meier plotter, the protein expression comparison of different CAPNs in human tumor/normal tissues from The Human Protein Atla, the CAPNs gene alterations through cBioPortal, the prediction of protein-protein interactions by STRING and GeneMANIA, the functional enrichment of discrepant CAPNs by GO and KEGG, and the immune infiltration of CAPNs by ssGSEA. RESULTS Our results showed that CAPN1, 2, 4, 5, 6, 8, 9, 10, and 12 were highly expressed in PC. CAPN1, 5, 8, and 12 expression levels were positively correlated with individual cancer stages. Furthermore, CAPN1, 2, 5, and 8 expression levels were negatively correlated with overall survival (OS) and recurrence-free survival (RFS), while CAPN10 was positively correlated with OS and RFS. We found that CAPN1, 2, 5, and 8 were correlated with tumor-infiltrating T follicular helper cells and CAPN10 with tumor-infiltrating T helper 2 cells. Functional enrichment analysis showed that differentially expressed CAPNs (CAPN1, 2, 5, 8, and 10) are involved in axonogenesis, cell-substrate adhesion, immune response-activating cell surface receptor signaling pathway, and cell junction organization in PC. CONCLUSIONS These results suggested that CAPN1, 2, 5, 8, and 10 could be used as prognostic biomarkers in PC and improve individualized treatment strategies.

Abstract
Researchers are developing new techniques and technologies to determine the characteristic features for cancer progression, thereby identifying potential targets and therapeutics to interfere these hallmark processes of cancer pathogenesis. The transformative researches using these in vitro methods have enable researchers to design precision treatments of patients with esophageal squamous cell carcinoma (ESCC). These in vitro methods mainly include analysis of cell proliferation, cytotoxicity, colony formation, invasion, and migration in ESCC cells for analyzing manipulations affecting the biological behavior of ESCC. Because of these studies, important information on molecular mechanisms of different genes and proteins as well as result of therapeutic interventions are confirmed in ESCC.

Abstract
Autophagy-related genes (ATGs) depress tumorigenesis. However, in tumor tissue, it promotes tumor progression. Here, we demonstrated that 63 ATGs were differentially expressed in normal tissues and tumor tissues of hepatocellular carcinoma (HCC), and seven prognostic-related genes were chosen to establish prognostic risk signatures. It is not just an independent prognostic factor for HCC, but also closely related to the degree of malignancy of HCC. Further, the hallmarks of PI3K–AKT–mTOR signaling was significantly enriched in the high-risk group. Moreover, AKT–pS473 and mTOR–pS2448 expression was down-regulated and correlated with patient prognosis in high-risk group. Finally, we demonstrate that the prognosis signature of ATGs is closely related to immune cell infiltration and PD-L1 expression. In conclusion, ATGs are a crucial factor in the malignant progression of HCC and will be a new prognostic marker for diagnosis and treatment. ATGs prognostic signatures are potentially useful for predicting PD-L1 therapeutic effects.

Abstract
Background Long non‐coding RNA (lncRNA) has been regarded as crucial regulator for cancer progression. Roles of KCNQ1 opposite strand/antisense transcript 1 (KCNQ1OT1) in cancers including osteosarcoma and colon cancer have been previously reported. However, its role in ovarian cancer (OC) remains unclear. Methods Expression level of KCNQ1OT1 on OC cells and normal cell was analyzed with quantitative real‐time PCR. Gain and loss‐of‐function experiments were performed to analyze the biological roles of KCNQ1OT1 in OC. Moreover, whether KCNQ1OT1 functions its role via mediating MICRORNA‐142‐5p (MIR‐142‐5p)/calpain 10 (CAPN10) axis was analyzed. In addition, effects of KCNQ1OT1, MIR‐142‐5p, and CAPN10 on overall survival of OC patients were analyzed at Kaplan–Meier plotter website. Results We showed KCNQ1OT1 was elevated expression in OC cells and indicated poorer overall survival of OC patients. Besides, we found KCNQ1OT1 could promote OC cell proliferation and migration in vitro. Moreover, MIR‐142‐5p was found reduced expression, while CAPN10 was found elevated expression in OC cells compared with normal cell. Kaplan–Meier curve analysis showed low MIR‐142‐5p or high CAPN10 expression were indicators for poorer overall survival of OC patients. At length, we showed KCNQ1OT1 could regulate OC development via MIR‐142‐5p/CAPN10 axis. Conclusions Taken together, KCNQ1OT1 upregulates CAPN10 expression via sponging MIR‐142‐5p, thus promoting the proliferation and migration of OC.

Abstract
Whole-slide imaging (WSI) contributes to medical education, collaboration, quality assurance, examination, and consultation in pathology. The images obtained from WSI are of high quality and could be stored indefinitely. In research involving esophageal squamous cell carcinoma, the combination of WSI and image processing program allows effective interpretations of expressions of various immunomarkers related to pathogenesis, prognosis, and response to therapy in tissue microarray sections. The operation and basic principles of whole-slide imaging of esophageal squamous cell carcinoma are also presented. Common use of WSI will occur with modifications of the whole-slide imaging scanners to adapt to the workflows in diagnostic and research laboratories.

Abstract
Immunohistochemistry is the identification of a cell protein by a specific antibody targeting that protein. It is the most common ancillary test to study the pathology of cancer. Immunohistochemical protein markers are used to differentiate poorly differentiated squamous cell carcinoma from poorly differentiated adenocarcinoma or neuroendocrine carcinomas. They could be used to identify and type the carcinoma in metastatic locations. Importantly, immunodetection of markers also helps in prediction of response to therapies as well as assessing the different biomarkers related to the pathogenesis and clinical behavior of esophageal squamous cell carcinoma. Successful application of the immunochemistry depends on understanding the mechanisms and principles as well as the limitations of the procedure. Automation of the procedure by different models of automatic stainers is widely used in diagnostic laboratories. The use of autostainers streamlines the workflows and certainly reduces the labor, time, and cost of using immunohistochemistry in clinical and research settings.

Abstract
Although tenascin-C (TNC), an extracellular matrix protein, has been shown to be widely expressed in stromal fibroblasts in various cancers, the role of its expression in esophageal squamous cell carcinoma (ESCC) cells remains unclear. Using immunohistochemistry, we investigated the expression of cancer stem-like cell (CSC) markers, epithelial-to-mesenchymal transition (EMT)-related genes, and the Akt/hypoxia-inducible factor-1α (HIF1α) signal pathway in ESCC tissue specimens from 154 patients. We further addressed the effects of TNC on the Akt/HIF1α axis and its putative association with cancer stemness in several ESCC cell lines by immunofluorescence imaging and western blot analysis. Our data suggest that TNC expression was positively correlated with the expression of the CSC marker SOX2 (p = .002), and TNC-expressing cancer cells expressed SOX2 in ESCC tissues. Moreover, TNC expression was strongly associated with EMT-related gene Snail (p = .022) and positively correlated with pAkt-Ser473 (p = .004) and HIF1α (p = .003). Furthermore, TNC-silencing down-regulated the expression of CSC marker SOX2 (p < .001) and EMT-related marker Snail (p < .001). The Akt inhibitor Perifosine inhibited the protein expression of pAkt-Ser473, Akt, HIF1α, and TNC in TE10 (an ESCC cell line) cells. Short-term exposure of TE10 cells to cobalt chloride caused an increase in protein expression of HIF1α, TNC, and SOX2 in a time-dependent manner. Taken together, these results suggest that TNC may enhance the cancer stem-like properties and promote EMT-like changes via the Akt/HIF1α axis.

Abstract
Family with sequence similarity 134, member B (FAM134B) is an autophagy regulator of endoplasmic reticulum first discovered to be involved in the pathogenesis of esophageal squamous cell carcinoma (ESCC). The present study examined the functional behavior of FAM134B in cancer cells and the association of FAM134B expression with clinicopathologic factors in patients with ESCC. Expression at both the mRNA and protein levels was investigated using real-time polymerase chain reaction and immunohistochemistry. The results were correlated with the clinical and pathological features of the patients. In addition, in vitro functional assays were used to investigate the roles of FAM134B in ESCC cells in response to gene silencing with shRNA lentiviral particles. Overexpression of FAM134B mRNA and protein was present in 31.2% (n = 29/93) and 36.6% (n = 41/112), respectively, in tumors, whereas downregulation occurred in 39.8% (n = 37/93) and 63.4% (n = 71/112), respectively. Expression of FAM134B protein in ESCC correlated with histologic grade (P = .002) and pathologic stage (P = .012). In vitro suppression of FAM134B in ESCC induced significant reductions of cell proliferation and colony formation (P < .05). In addition, suppression of FAM134B caused reduction of wound healing, migration, and invasion capacities of ESCC. To conclude, FAM134B could play crucial roles in the initiation and progression of ESCC, and FAM134B protein expression has potential predictive value. Therefore, development of strategies targeting FAM134B could have therapeutic value in the management of patients with ESCC.

Cells 2018; 7:cells7100143. [PMID: 30241323 PMCID: PMC6210716 DOI: 10.3390/cells7100143] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2018] [Revised: 09/16/2018] [Accepted: 09/16/2018] [Indexed: 01/18/2023] Open
Abstract
Cisplatin (CDDP) is one of the front-line chemotherapeutic drugs used in the treatment of esophageal squamous cell carcinoma (ESCC). Occurrence of resistance to CDDP has become one of the main challenges in cancer therapy. In this study, the gene expression profile of CDDP-resistant ESCC cells was investigated and molecular approaches were explored in an attempt to reverse the CDDP resistance. A CDDP-resistant SLMT-1/CDDP1R cell line was established from SLMT-1 cells by subculturing in the medium containing an increasing concentration of CDDP (0.1–1μg/mL). Mitochondrial (MTS) cytotoxicity assay, cell proliferation assay and cell morphology were used to assess the acquisition of cisplatin-resistance. The most differentially expressed gene in SLMT-1/CDDP1R cells was identified by cDNA microarray analysis compared with the parental SLMT-1 cells and validated by quantitative real-time polymerase chain reaction (qPCR). Association between expression of the most differentially expressed target gene to cisplatin-resistance was verified by RNA interference. An attempt to reversecisplatin-resistance phenotypes was made by using the vector expressing the most downregulated target gene in the CDDP-resistant cells. A CDDP-resistant ESCC cell line, SLMT-1/CDDP1R, was established with 2.8-fold increase CDDP-resistance (MTS50 = 25.8 μg/mL) compared with the parental SLMT-1 cells. cDNA microarray analysis revealed that IGFBP5 showed the highest level of downregulation in SLMT-1/CDDP1R cells compared with the parental SLMT-1 cells. Suppression of IGFBP5 mediated by IGFBP5-targeting siRNA in parental SLMT-1 cells confirmed that IGFBP5 suppression in ESCC cells would induce CDDP-resistance. More importantly, upregulation of IGFBP5 using IGFBP5 expression vector reduced cisplatin-resistance in SLMT-1/CDDP1R cells by 41%. Thus, our results demonstrated that IGFBP5 suppression is one of the mechanisms for the acquisition of cisplatin-resistance in ESCC cells. Cisplatin-resistance phenotype can be reversed by increasing the expression level of IGFBP5. The overall findings of this study thus offered a new direction for reversing the CDDP resistance in ESCC and possibly in other cancer types with further investigations in future.

Abstract
GAEC1 (gene amplified in oesophageal cancer 1) is a transforming oncogene with tumorigenic potential observed in both oesophageal squamous cell carcinoma and colorectal cancer. Nonetheless, there has been a lack of study done on this gene to understand how this gene exert its oncogenic properties in cancer. This study aims to identify novel mutation sites in GAEC1. To do so, seventy-nine matched colorectal cancers were tested for GAEC1 mutation via Sanger sequencing. The mutations noted were investigated for the correlations with the clinicopathological parameters of the patients with the cancer. Additionally, GAEC1 copy number aberration (CNA), mRNA and protein expression were determined with the use of droplet digital (dd) polymerase chain reaction (PCR), real-time PCR and Western blot (confirmed with immunofluorescence analysis). GAEC1 mutation was noted in 8.8% (n = 7/79) of the cancer tissues including one missense mutation, four loss of heterozygosity (LOH) and two substitutions. These mutations were significantly associated with cancer perforation (p = 0.021). GAEC1 mutation is frequently associated with increased GAEC1 protein expression. Nevertheless, GAEC1 mRNA and protein are only weakly associated. Taken together, GAEC1 mutation affects GAEC1 expression and is associated with poorer clinical outcomes. This further strengthens the role of GAEC1 as an oncogene.

Muhanhali D, Zhai T, Jiang J, Ai Z, Zhu W, Ling Y. Long Non-coding Antisense RNA TNRC6C-AS1 Is Activated in Papillary Thyroid Cancer and Promotes Cancer Progression by Suppressing TNRC6C Expression. Front Endocrinol (Lausanne) 2018; 9:360. [PMID: 30038597 PMCID: PMC6046411 DOI: 10.3389/fendo.2018.00360] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2018] [Accepted: 06/18/2018] [Indexed: 01/08/2023] Open
Abstract
Context: Evidences have shown the important role of long non-coding antisense RNAs in regulating its cognate sense gene in cancer biology. Objective: Investigate the regulatory role of a long non-coding antisense RNA TNRC6C-AS1 on its sense partner TNRC6C, and their effects on the aggressiveness and iodine-uptake ability of papillary thyroid cancer (PTC). Design: TNRC6C-AS1 was identified as the target long non-coding RNA in PTC by using microarray analysis and computational analysis. In vitro gain/loss-of-function experiments were performed to investigate the effects of TNRC6C-AS1 and TNRC6C on proliferation, apoptosis, migration, invasion and iodine-uptake ability of TPC1 cells. Expression levels of TNRC6C-AS1 and TNRC6C of 30 cases of PTC tissues and its adjacent normal thyroid tissues were determined. Results: Downregulation of TNRC6C-AS1 or overexpression of TNRC6C inhibited proliferation, migration and invasion of TPC1 cells, while apoptosis and iodine uptake was promoted in TPC1 cells. Suppression of TNRC6C-AS1 significantly increased the expression of TNRC6C in TPC1 cells. The inhibitory effect of TNRC6C-AS1 knockdown on cell proliferation, migration and invasion was attenuated when the expression of TNRC6C was suppressed simultaneously, indicating TNRC6C is a functional target of TNRC6C-AS1. The expression of TNRC6C-AS1 was significantly higher, while the TNRC6C mRNA and protein were significantly lower in PTC tissues than normal adjacent tissues. There was a significant inverse correlation between TNRC6C-AS1 and TNRC6C mRNA in PTC tissue samples. Conclusions: TNRC6C-AS1 promotes the progression of PTC and inhibits its ability of iodine accumulation by suppressing the expression of TNRC6C. Targeting TNRC6C-AS1 - TNRC6C axis may be a new promising treatment for PTC.

Abstract
GAEC1 (Gene amplified in esophageal cancer 1) alterations have oncogenic properties in oesophageal squamous cell carcinomas and frequent amplifications of the gene were noted in colorectal adenocarcinomas. However, the subcellular localization and expression of GAEC1 at the protein level have never been reported in human cancer cells. The present study aimed to investigate whether GAEC1 is differentially expressed in different stages of colon cancer and to elucidate its underlying cellular and molecular mechanism in colon cancer progression. We found differential expression of GAEC1 protein and mRNA in different pathological stages of colon cancer cells (SW480-Stage II, SW48-Stage III and HCT116-Stage IV) when compared to non-neoplastic colon cells (FHC cells) by immunocytochemistry, immunofluorescence, western blot analysis and real-time polymerase chain reaction. GAEC1 protein was predominantly expressed in the cytoplasm of colon cancer cells (SW480, SW48, and HCT116) and in the nucleus of non-neoplastic colon epithelial cells (FHC cells). The transient knockdown of GAEC1 using siRNA induced apoptosis in SW480 and SW48 cells, which was associated with G2/M phase arrest and decreased expression of bcl-2 and K-ras proteins and increased expression of p53. In addition, down-regulation of GAEC1 significantly inhibited (p<0.05) cell proliferation, reduced migration capacity and decreased clonogenic potentiality of colon cancer cells (SW480 and SW48 cells). Furthermore, a xenotransplantation model showed that stable knockdown of GAEC1 using shRNA constructs in colon cancer cells fully suppressed xenograft tumour growth in mice. Collectively, the expression analysis, in vitro and in vivo data indicated that GAEC1 is differentially expressed in cancer cells and act as an oncogene in colon cancer progression.

Abstract
Previous study found that higher Capn4 mRNA level is observed in patients with more advanced pathological stage of ccRCC and is also associated with decreased overall survival of patients with ccRCC. However, the mechanism by which Capn4 promotes progression of RCC is not understood. In the present study, we found that over-expression of Capn4 in RCC cells enhances tumor cell growth and down-regulation of Capn4 in RCC cells decreases tumor cell growth in vitro. Interestingly, Capn4 was found to increase phosphorylation of specific tyrosine residues of FAK and subsequent activate NF-κB p65 phosphorylation. Furthermore, Capn4-mediated cell proliferation of RCC cells required up-regulation of NF-κB p65 phosphorylation through activation of FAK signaling pathway. Taken together, our data showed that Capn4 can contribute to RCC growth via activation of the FAK and the downstream signaling pathways leading to the activation of NF-κB.

Abstract
Mutation of FAM134B (Family with Sequence Similarity 134, Member B) leading to loss of function of its encoded Golgi protein and has been reported induce apoptosis in neurological disorders. FAM134B mutation is still unexplored in cancer. Herein, we studied the DNA copy number variation and novel mutation sites of FAM134B in a large cohort of freshly collected oesophageal squamous cell carcinoma (ESCC) tissue samples. In ESCC tissues, 37% (38/102) showed increased FAM134B DNA copies whereas 35% (36/102) showed loss of FAM134B copies relative to matched non-cancer tissues. Novel mutations were detected in exons 4, 5, 7, 9 as well as introns 2, 4-8 of FAM134B via HRM (High-Resolution Melt) and Sanger sequencing analysis. Overall, thirty-seven FAM134B mutations were noted in which most (31/37) mutations were homozygous. FAM134B mutations were detected in all the cases with metastatic ESCC in the lymph node tested and in 14% (8/57) of the primary ESCC. Genetic alteration of FAM134B is a frequent event in the progression of ESCCs. These findings imply that mutation might be the major driving source of FAM134B genetic modulation in ESCCs.

Abstract
Cancer stem cells (CSCs) are a vital subpopulation of cells to target for the treatment of cancers. In oesophageal squamous cell carcinoma (ESCC), there are several markers such as CD44, ALDH, Pygo2, MAML1, Twist1, Musashi1, Side population (SP), CD271 and CD90 that have been proposed to identify the cancer stem cells in individual cancer masses. It has also been demonstrated that stem cell markers like ALDH1, HIWI, Oct3/4, ABCG2, SOX2, SALL4, BMI-1, NANOG, CD133 and podoplanin are associated with patient's prognosis, pathological stages, cancer recurrence and therapy resistance. Finding new cancer stem cell targets or designing drugs to manipulate the known molecular targets in CSCs could be useful for improvements in clinical outcomes of the disease. To conclude, data suggest that CSCs in oesophageal squamous cell carcinoma are related to resistance to therapy and poor prognosis of patients with ESCC. Therefore, innovative insights into CSC biology and CSC-targeted therapies will help to achieve more effective management of patients with oesophageal squamous cell carcinoma.

Abstract
Aberrant expressions of micro-ribonucleic acids (miRs) are closely associated with the pathogenesis in many human cancers. In oesophageal adenocarcinomas, altered expressions of different sets of miRs are noted to be associated with the development of adenocarcinoma from Barrett's oesophagus. In different studies, miRs such as miR-192, miR-196 and miR-21 were frequently noted to up-regulated whereas miR-203, miR-205 and miR-let-7 were commonly down-regulated during the development of Barrett's oesophagus to oesophageal adenocarcinoma. In addition, changes in the expression of miRs are associated with the predication of metastasis, prognosis and response to chemo-radiation in the patients with oesophageal adenocarcinoma. Experimental studies in manipulating the miRs in cancer cell lines could provide hints for therapeutics for the cancer. However, the number of studies reported on these aspects of oesophageal adenocarcinoma was limited and the miRs noted needed to be confirmed by additional studies. Overall, the mechanisms of involvements of miRs in pathogenesis and progression of oesophageal adenocarcinoma are complex. Although miRs have the potential to act as prognostic and clinical biomarkers for cancer therapy in oesophageal adenocarcinoma, more works in larger populations and clinical trials are needed to validate these clinical implications.

Abstract
Calpain activity has been implicated in several cellular processes such as cell signaling, apoptosis, exocytosis, mitochondrial metabolism and cytoskeletal remodeling. Evidence has indicated that the impairment of calpain expression and the activity of different calpain family members are involved in diverse pathologies. Calpain-10 has been implicated in the development of type 2 diabetes, and polymorphisms in the CAPN10 gene have been associated with an increased risk of developing this disease. The present work focused on the molecular biology of calpain-10, supporting its key participation in glucose metabolism. Current knowledge regarding the role of calpain-10 in the development of type 2 diabetes mellitus and diabetes-related diseases is additionally reviewed.
