Abstract
Hepatocellular carcinoma (HCC) poses a global health challenge. Effective biomarkers are required for early diagnosis to improve survival rates of patients with HCC. Spindle and kinetochore-associated complex subunits 1 (SKA1) is essential for proper chromosome segregation in the mitotic cell cycle. Previous studies have shown that overexpression of SKA1 is associated with a poor prognosis in various cancers. The expression, prognostic value, and clinical functions of SKA1 in HCC were evaluated with several bioinformatics web portals. Additionally, we identified target long non-coding RNAs (lncRNAs) and microRNAs by analyzing messenger RNA (mRNA)-miRNA and miRNA-lncRNA interaction data and elucidated the potential competing endogenous RNA (ceRNA) mechanism associated with SKA1. High SKA1 expression was associated with poor prognosis in patients with HCC. Furthermore, multivariate Cox regression analysis revealed that SKA1 expression was an independent prognostic factor for HCC. GO and KEGG analyses showed that SKA1 is related to the cell cycle checkpoints, DNA replication and repair, Rho GTPases signaling, mitotic prometaphase, and kinesins. Gene set enrichment analysis revealed that high levels of SKA1 are associated with cancer-promoting pathways. DNA methylation of SKA1 in HCC tissues was lower than that in normal tissues. Ultimately, the following 9 potential ceRNA-based pathways targeting SKA1 were identified: lncRNA: AC026401.3, Small Nucleolar RNA Host Gene 3 (SNHG3), and AC124798.1-miR-139-5p-SKA1; lncRNA: AC26356.1, Small Nucleolar RNA Host Gene 16 (SNHG16), and FGD5 Antisense RNA 1-miR-22-3p-SKA1; lncRNA: Cytoskeleton Regulator RNA (CYTOR), MIR4435-2 Host Gene, and differentiation antagonizing non-protein coding RNA-miR-125b-5p-SKA1. SKA1 expression levels significantly correlated with immune cell infiltration and immune checkpoint genes in the HCC tissues. SKA1 is a potential prognostic biomarker for HCC. This study provides a meaningful direction for research on SKA1-related mechanisms, which will be beneficial for future research on HCC-related molecular biological therapies and targeted immunotherapy.

Liu T, Ding D, Wang W, Wu Y, Ma D, Liu M, Tan Z, Yao J, Li X. The role and clinical significance of microRNA-29a-3p in the development of hypopharyngeal carcinoma. Braz J Otorhinolaryngol 2023; 89:401-409. [PMID: 37116374 PMCID: PMC10165196 DOI: 10.1016/j.bjorl.2023.03.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 02/24/2023] [Accepted: 03/01/2023] [Indexed: 03/12/2023] Open
Abstract
OBJECTIVE MicroRNA-29a-3p has been reported in a variety of cancers, but its role in hypopharyngeal cancer remains unclear. This study was to determine the role of microRNA-29a-3p in the occurrence and development of hypopharyngeal cancer. METHODS 40 patients with hypopharyngeal cancer who underwent surgery in the Affiliated Hospital of Jining Medical University from April 2013 to November 2017 were selected for this study. The cancer tissue samples of the patients were collected, and the patients were followed up for three years. The expression of microRNA-29a-3p in tissue samples was detected by in situ hybridization with fluorescent probe, and the relationships among microRNA-29a-3p and clinicopathological factors, postoperative recurrent-metastasis, survival time were studied. Immunohistochemical was used to detect the expression of Ki67 and E-cadherin in tissue samples. RESULTS Combined with HE staining results showed that microRNA-29a-3p expression was relatively high in non-cancer tissue cells (red blood cells and fibroblasts in tumor interstitial vessels), but was relatively low in cancer tissue and cells. According to the follow-up data of 40 patients with hypopharyngeal cancer, tumor size, T-stage, tumor differentiation, postoperative recurrent-metastasis of hypopharyngeal cancer patients were significantly negatively correlated with microRNA-29a-3p (p < 0.05). Immunohistochemica results further confirmed that microRNA-29a-3p was negatively correlated with the expression of Ki67 and E-cadherin. The survival time of patients positively related with microRNA-29a-3p expression (p < 0.05). Moreover, ROC curve analysis showed that the area under the curve of the combined detection of miRNA-29a-3p+Ki67+E-cadherin was larger than that of the single detection of the three indexes. CONCLUSIONS The expression of microRNA-29a-3p is closely related to the occurrence, development and prognosis of hypopharyngeal cancer, and it affects the proliferation and invasion. This indicates that microRNA-29a-3p serves as a therapeutic target for the occurrence and development of hypopharyngeal cancer. The evidence of study designs of this study is IV using "Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence".

Abstract
Gap junctions (GJs), essential structures for cell-cell communication, are made of two hemichannels (commonly called connexons), one on each adjacent cell. Found in almost all cells, GJs play a pivotal role in many physiological and cellular processes, and have even been linked to the progression of diseases, such as cancer. Modulation of GJs is under investigation as a therapeutic strategy to kill tumor cells. Furthermore, GJs have also been studied for their key role in activating anti-cancer immunity and propagating radiation- and oxidative stress-induced cell death to neighboring cells, a process known as the bystander effect. While, gap junction (GJ)-based therapeutic strategies are being developed, one major challenge has been the paradoxical role of GJs in both tumor progression and suppression, based on GJ composition, cancer factors, and tumoral context. Therefore, understanding the mechanisms of action, regulation, and the dual characteristics of GJs in cancer is critical for developing effective therapeutics. In this review, we provide an overview of the current understanding of GJs structure, function, and paradoxical pro- and anti-tumoral role in cancer. We also discuss the treatment strategies to target these GJs properties for anti-cancer responses, via modulation of GJ function.

Abstract
The emerging roles of extracellular vesicles (EVs) in bladder cancer have recently been identified. This study aims to elucidate the role of microRNA-139-5p (miR-139-5p) shuttled by bone marrow mesenchymal stem cells (BMSCs)-derived EVs (BMSCs-EVs) in bladder cancer, with the possible mechanism explored. Expression of miR-139-5p and KIF3A was tested, followed by an analysis of their correlation. EVs were isolated from BMSCs and co-cultured with T24 or BOY-12E cells with miR-139-5p mimic/inhibitor, oe-KIF3A, and/or si-p21 transfected to study the roles of miR-139-5p/KIF3A/p21 in bladder cancer cell functions. A nude mouse model of subcutaneous xenograft tumor was constructed to detect the effect of miR-139-5p in BMSCs-EVs on the tumorigenesis and lung metastasis of bladder cancer cells in vivo. It was identified that miR-139-5p was highly expressed in BMSCs-EVs, but poorly expressed in bladder cancer. BMSCs-EVs transferred miR-139-5p into bladder cancer cells where miR-139-5p inhibited the malignant features of bladder cancer cells in vitro. miR-139-5p in BMSCs-EVs targeted KIF3A and inhibited the expression of KIF3A, thereby activating p21. miR-139-5p in BMSCs-EVs arrested the tumorigenesis and lung metastasis of bladder cancer cells in vivo by modulation of the KIF3A/p21 axis. Altogether, BMSCs-EVs carried miR-139-5p targeted KIF3A to activate p21, thus delaying the occurrence of bladder cancer.

Abstract
OBJECTIVE The overall aim is to study the effect of detailed nursing interventions on the safety and stress responses of tumor patients. METHODS A total of 100 patients who underwent tumor surgery between August 2017 and August 2019 were included and randomized into an experimental group (n=50) and a control group (n=50). Both groups were administered conventional nursing, and based on that, the experimental group was treated with detailed nursing. The two groups were compared in terms of their blood pressure changes, serum norepinephrine (NE), epinephrine (E), cortisol, nursing quality, and Self-Rating Depression/Anxiety Scale (SDS/SAS) scores. The incidences of adverse reactions and the nursing satisfaction were also compared. RESULTS After the nursing, the experimental group had better results in their blood pressure levels, stress indexes, nutritional status, and nursing quality (P<0.05). Compared with the control group, lower SDS/SAS scores, fewer accidents, and higher nursing satisfaction were observed in the experimental group (P<0.05). The progression-free survival rates at 6 and 12 months after the operations were significantly higher in the experimental group than that in the control group (P<0.05). CONCLUSION Detailed nursing interventions can substantially improve the psychological conditions of patients with tumors and diminish their adverse stress responses with a high safety profile, so it is worthy of clinical promotion and application.

Abstract
Background: The pathogenesis of osteosarcoma (OS) is still unclear, and it is still necessary to find new targets and drugs for anti-OS. This study aimed to investigate the role and mechanism of the anti-OS effects of miR-296-5p. Methods: We measured the expression of miR-296-5p in human OS cell lines and tissues. The effect of miR-296-5p and its target gene staphylococcal nuclease and tudor domain containing 1 on proliferation, migration, and invasion of human OS lines was examined. The Student's t test was used for statistical analysis. Results: We found that microRNA (miR)-296-5p was significantly downregulated in OS cell lines and tissues (control vs. OS, 1.802 ± 0.313 vs. 0.618 ± 0.235, t = 6.402, P < 0.01). Overexpression of miR-296-5p suppressed proliferation, migration, and invasion of OA cells. SND1 was identified as a target of miR-296-5p by bioinformatic analysis and dual-luciferase reporter assay. Overexpression of SND1 abrogated the effects induced by miR-296-5p upregulation (miRNA-296-5p vs. miRNA-296-5p + SND1, 0.294 ± 0.159 vs. 2.300 ± 0.277, t = 12.68, P = 0.003). Conclusion: Our study indicates that miR-296-5p may function as a tumor suppressor by targeting SND1 in OS.

Connexins-Therapeutic Targets in Cancers. Int J Mol Sci 2020; 21:ijms21239119.

Abstract
Connexins (Cx) are members of a protein family that forms intercellular channels localised in gap junction (GJ) plaques and single transmembrane channels called hemichannels. They participate in intercellular communication or communication between the intracellular and extracellular environments. Connexins affect cell homeostasis, growth and differentiation by enabling the exchange of metabolites or by interfering with various signalling pathways. Alterations in the functionality and the expression of connexins have been linked to the occurrence of many diseases. Connexins have been already linked to cancers, cardiac and brain disorders, chronic lung and kidney conditions and wound healing processes. Connexins have been shown either to suppress cancer tumour growth or to increase tumorigenicity by promoting cancer cell growth, migration and invasiveness. A better understanding of the complexity of cancer biology related to connexins and intercellular communication could result in the design of novel therapeutic strategies. The modulation of connexin expression may be an effective therapeutic approach in some types of cancers. Therefore, one important challenge is the search for mechanisms and new drugs, selectively modulating the expression of various connexin isoforms. We performed a systematic literature search up to February 2020 in the electronic databases PubMed and EMBASE. Our search terms were as follows: connexins, hemichannels, cancer and cancer treatment. This review aims to provide information about the role of connexins and gap junctions in cancer, as well as to discuss possible therapeutic options that are currently being studied.

Serum LUCAT1 implicates the pathogenesis of muscle-invasive bladder cancer via targeting miR-199a-5p and miR-199b-5p. J Mol Histol 2020; 51:583-591. [PMID: 32844284 DOI: 10.1007/s10735-020-09907-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Accepted: 08/20/2020] [Indexed: 12/24/2022]
Abstract
Muscle-invasive bladder cancer (MIBC) is a common malignancy of urinary system cancers, accounting for about 1/3 of all newly diagnosed bladder cancer cases. Due to its strong metastasis, the 5-year survival of MIBC is less than 50%, and in serious cases, the overall survival of metastatic bladder cancer patients is about 1.3 years. LncRNAs, a type of non-coding RNAs defined as the transcripts exceeding 200 nucleotides in length, are frequently aberrant in multiple cancers including cervical, ovarian, breast and bladder cancers. Recently, LUCAT1 (short for lung cancer-associated transcript 1), a lncRNA first reported to be involved in smoking-related lung cancer, has been observed to exhibit crucial roles in the epithelial-to-mesenchymal transition (EMT), migration and invasion processes of clear cell renal cell carcinoma (ccRCC) and colorectal cancer. However, whether it involves in the pathogenesis of MIBC remains underexplored. In the present study, LUCAT1 was up-regulated in the serum samples of MIBC patients and bladder cancer cell lines, as assessed using real-time PCR. Our in vitro data (including wound healing and trans-well assays) showed that LUCAT1 was required for the proliferation, EMT, migration and invasion processes of T24 cells. Moreover, LUCAT1 directly targeted miR-199a-5p and miR-199b-5p, as affirmed using the luciferase reporter assay, and manipulation of LUCAT1 significantly suppressed miR-199a-5p and miR-199b-5p. Collectively, our findings highlight an axis of LUCAT1/miR-199a/b-5p in MIBC pathogenesis. Therefore, LUCAT1 may possibly be a promising candidate for diagnostic biomarker and therapeutic target of MIBC.

Abstract
miRNAs are a group of non-coding RNAs that have regulatory functions in post-transcriptional gene expression. These molecules play a fundamental role in cellular processes, for instance cell proliferation, apoptosis, migration, and invasion. Scientific investigations have previously established that miRNAs can either promote or suppress tumor development by mediating different signaling pathways. miR-139-5p, located on chromosome 11q13.4, has been examined extensively in cancers. Studies have demonstrated that miR-139-5p might be an attractive cancer biomarker. Herein, we will review how miR-139-5p acts in cancer diagnosis, prognosis, and therapy, as well as elucidating its major target genes and associated signaling pathways.
