Abstract
BACKGROUND Leguminous Sophora moorcroftiana (SM) is a genuine medicinal material in Tibet. Many research results have reveal the Sophora moorcroftiana alkaloids (SMA), as the main active substance, have a wide range of effects, such as antibacterial, antitumor and antiparasitic effects. However, there are few reports on the inhibition of lung cancer (LC) and its inhibitory mechanism, and the pharmacological mechanism of SMA is still unclear, Therefore, exploring its mechanism of action is of great significance. METHODS The SMA active components were obtained from the literature database. Whereas the corresponding targets were screened from the PubChem and PharmMapper database, UniProt database were conducted the correction and transformation of UniProt ID on the obtained targets. The GeneCards and OMIM databases identified targets associated with LC. Venny tools obtained the intersection targets of SMA and LC. R language and Cytoscape software constructed the visual of SMA - intersection targets - LC disease network. The intersection targets protein-protein interaction (PPI) network were built by the STRING database. The functions and pathways of the common targets of SMA and LC were enriched by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). Subsequently, molecular docking And A549 cells vitro experiment were performed to further validate our finding. RESULTS We obtained six kinds of alkaloids in SM, 635 potential targets for these compounds, and 1,303 genes related to LC. SMA and LC intersection targets was 33, including ALB, CCND1, ESR1, NOTCH1 and AR. GO enrichment indicated that biological process of SMA was mainly involved in the positive regulation of transcription and nitric oxide biosynthetic process, and DNA-templated, etc. Biological functions were mainly involved in transcription factor binding and enzyme binding, etc. Cell components were mainly involved in protein complexes, extracellular exosome, cytoplasm and nuclear chromatin, etc., Which may be associated with its anti-LC effects. KEGG enrichment analysis showed that main pathways involved in the anti-LC effects of SMA, including pathway in cancer, non small-cell lung cancer, p53, PI3K-Akt and FOXO signaling pathways. Molecular docking analyses revealed that the six active compounds had a good binding activity with the main therapeutic targets 2W96, 2CCH and 1O96. Experiments in vitro proved that SMA inhibited the proliferation of LC A549 cells. CONCLUSIONS Results of the present study, we have successfully revealed the SMA compounds had a multi-target and multi-channel regulatory mechanism in treatment LC, These findings provided a solid theoretical reference of SMA in the clinical treatment of LC.

Cancer-associated fibroblast-derived exosomal miR-18b promotes breast cancer invasion and metastasis by regulating TCEAL7. Cell Death Dis 2021; 12:1120. [PMID: 34853307 PMCID: PMC8636636 DOI: 10.1038/s41419-021-04409-w] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 11/06/2021] [Accepted: 11/15/2021] [Indexed: 11/09/2022]
Abstract
Studies have shown that cancer-associated fibroblasts (CAFs) play an irreplaceable role in the occurrence and development of tumors. Therefore, exploring the action and mechanism of CAFs on tumor cells is particularly important. In this study, we compared the effects of CAFs-derived exosomes and normal fibroblasts (NFs)-derived exosomes on breast cancer cells migration and invasion. The results showed that exosomes from both CAFs and NFs could enter into breast cancer cells and CAFs-derived exosomes had a more enhancing effect on breast cancer cells migration and invasion than NFs-derived exosomes. Furthermore, microRNA (miR)-18b was upregulated in CAFs-derived exosomes, and CAFs-derived exosomes miR-18b can promote breast cancer cell migration and metastasis by specifically binding to the 3'UTR of Transcription Elongation Factor A Like 7 (TCEAL7). The miR-18b-TCEAL7 pathway promotes nuclear Snail ectopic activation by activating nuclear factor-kappa B (NF-κB), thereby inducing epithelial-mesenchymal transition (EMT) and promoting cell invasion and metastasis. Moreover, CAFs-derived exosomes miR-18b could promote mouse xenograft model tumor metastasis. Overall, our findings suggest that CAFs-derived exosomes miR-18b promote nuclear Snail ectopic by targeting TCEAL7 to activate the NF-κB pathway, thereby inducing EMT, invasion, and metastasis of breast cancer. Targeting CAFs-derived exosome miR-18b may be a potential treatment option to overcome breast cancer progression.

Abstract
Colon carcinoma is one of the most common cancers worldwide. Epidemiological studies have revealed that colon cancer is the third leading cause of cancer-related deaths, which is due to the increased incidence and mortality rates. However, the treatment strategies for colon cancer remain unsatisfactory for patients, especially for those with advanced or recurrent colon cancer. Dysregulated microRNAs (miRNAs) are considered to influence tumor development and metastasis. However, the molecular mechanism through which miRNAs affect cancer progression is not yet completely understood. The aim of the present study was to investigate the expression levels of has-miR-15a-5p and its molecular mechanism in colon cell carcinoma. In the present study, the expression levels of hsa-miR-15a-5p were found to be decreased in colon tumor tissues and cancer cell lines. Hsa-miR-15a-5p overexpression inhibited colon cell proliferation and migration. Mechanistically, the G1/S-specific cyclin-D1 (CCND1) gene was predicted as a target of hsa-miR-15a-5p, as evidenced by bioinformatics and dual-luciferase reporter assay analyses. CCND1 overexpression significantly increased the progression of colon cancer. Furthermore, CCND1 was demonstrated to mediate the effects of hsa-miR-15a-5p on colon cancer cells. The present study demonstrated that hsa-miR-15a-5p alleviated the proliferation, migration and invasion of colon cancer by targeting the CCND1 gene, which represents a potential molecular target for the diagnosis and treatment of colon cancer.

Abstract
Recently, circular RNAs (circRNAs/circs) have attracted increased attention due to their regulatory role in a variety of cancer types. However, the role and molecular mechanisms of circRNAs in cervical cancer (CC) remain unknown. The present study aimed to investigate the function of hsa_ circ_0101119 on CC and its potential mechanisms. The differentially expressed circRNAs associated with CC were screened out using R software, according to the database of Gene Expression Omnibus (GEO). The expression levels of hsa_circ_0101119, eukaryotic initiation factor 4A‑3 (EIF4A3) and transcription elongation factor A‑like 6 (TCEAL6) in CC cells were detected via reverse transcription‑quantitative (RT‑q)PCR, and their expression levels in CC tissues were analyzed based on the database of GEO and the Cancer Genome Atlas. Moreover, the accurate functions of hsa_circ_0101119 and TCEAL6 on the proliferation, apoptosis, migration and invasion of SiHa and HeLa cells was examined using colony formation assay, 5‑ethynyl‑20‑deoxyuridine incorporation assay, flow cytometry and Transwell assay. Next, the underlying mechanisms of hsa_circ_0101119 on CC progression were determined via bioinformatics analysis, RNA immunoprecipitation assay, RNA pull down assay, RT‑qPCR and western blotting. It was found that hsa_circ_0101119 was highly expressed in CC tissues and cells, while TCEAL6 was lowly expressed. Knockdown of hsa_circ_0101119 or TCEAL6 overexpression significantly inhibited the proliferation, migration and invasion of SiHa and HeLa cells, but facilitated apoptosis. It was also demonstrated that hsa_circ_0101119 could recruit EIF4A3 to inhibit TCEAL6 expression in CC. Furthermore, knockdown of TCEAL6 could reverse the effects of silencing hsa_circ_0101119 on the proliferation, apoptosis, migration and invasion of HeLa cells. In conclusion, the present study revealed that hsa_circ_0101119 could facilitate cell proliferation, migration and invasion, and suppress apoptosis in CC via an interaction with EIF4A3 to inhibit TCEAL6 expression, which may provide a potential therapeutic target for CC treatment.

Abstract
BACKGROUND To explore the expression of microribonucleic acid-340 (miR-340) and cyclin D1 (CCND1) in lung cancer (LC) tissues and its relationship with the clinicopathological characteristics and prognosis of LC. METHODS Cancer tissues and paracancerous normal lung tissues of 65 patients with LC admitted to our hospital from January 2014 to March 2015 were included as the LC group, and the paracancerous group, respectively. RESULTS The relative expression levels of miR-340 mRNA and miR-340 protein in the LC group were lower than those in the paracancerous group, while the relative expression levels of CCND1 mRNA and CCND1 protein in the LC group were higher than those in the paracancerous group (P < 0.05). Pearson correlation analysis results showed that the mRNA and protein expression of both miR-340 and CCND1 in LC tissues was negatively correlated (r < 0, P < 0.05).The high expression rate (HER) of miR-340 and high expression rate (PER) of CCND1 were related to the tumor size, lymph node metastasis, TNM staging, and degree of differentiation (P < 0.05). The patients with high expression (HE) of miR-340 showed increased 5-year SR compared with the patients with low expression of miR-340, and that of patients positive for CCND1 was lower than that of the patients negative for CCND1 (P < 0.05). CONCLUSION miR-340 was downregulated, whereas CCND1 was upregulated in LC tissues, and the expression levels of the two genes were closely related to the prognosis and clinicopathological characteristics of LC.

Abstract
Increasing evidence showed that Heart and Neural Crest Derivatives Expressed 2 antisense RNA 1 (HAND2-AS1) was involved in the progression of several cancers, but its expression and function in gastric cancer (GC) was rarely reported. HAND2-AS1 expression in GC tissues and cells was detected at first. Cell function assays were performed to investigate the biological roles of HAND2-AS1 in GC cells. Moreover, the genes regulated by HAND2-AS1 in GC were investigated. Downregulation of HAND2-AS1 was found in GC tissues and cell lines. HAND2-AS1 overexpression inhibited GC cell proliferation, invasion, and arrested cell cycle at G0/G1 phase, whereas HADN2-AS1 knockdown significantly promoted cell proliferation and invasion. Bioinformatic analysis showed there is a potential HADN2-AS1/microRNA-769-5p (miR-769-5p)/transcription elongation factor A like 7 (TCEAL7) axis in GC. Luciferase activity reporter system was used to confirm this link. Taken together, our study showed that HAND2-AS1 exerts its tumor suppressive role in GC via regulating miR-769-5p/TCEAL7.

Abstract
Background Ectopic expression of transcription elongation factor A (SII)-like 7 (TCEAL7) has been observed in several kinds of cancers, but its role in melanoma is still unclear. This study was carried out to investigate TCEAL7 role in melanoma progression, and uncover the underlying mechanisms. Methods TCEAL7 expression levels in melanoma tissues and cells were determined by using real-time quantitative PCR (RT-PCR) and western blotting. CCK-8, transwell chambers, flow cytometry, starch assay and tumorigenesis assay were applied to detect cell growth, invasion, apoptosis, migration and tumorigenesis, respectively. Results A low expression level of TCEAL7 was observed in melanoma tissues and cells, which was associated with malignant clinical process and poor prognosis. TCEAL7 negatively modulated AKT1, AKT2, c-Myc, N-cadherin and PCNA expression and inhibited cancer progression via decreasing AKT1 and c-Myc levels. In addition, TCEAL7 was negatively modulated by miR-758-3p which promoted melanoma progression. Moreover, overexpression of TCEAL7 abolished miR-758-3p role in promoting melanoma progression. Conclusion This study demonstrated that TCEAL7, regulated by miR-758-3p inhibited melanoma progression through decreasing the expression levels of c-Myc and AKT1.
