The latent expression pattern of Epstein-Barr Virus (EBV) genes in nasopharyngeal carcinoma (NPC) has been extensively investigated, and the expression of several lytic genes in NPC has been reported. However, comprehensive information through EBV transcriptome analysis in NPC is limited. We performed paired-end RNA-seq to systematically and comprehensively characterize the expression of EBV genes in NPC tissue and C666-1 NPC cell line, which consistently carries EBV. In addition to the transcripts restricted to type II latency infection, the type III latency EBNA3s genes and a substantial number of lytic genes, such as BZLF1, BRLF1, and BMRF1, were detected through RNA-seq and were further verified in C666-1 cells and NPC tissue through real-time PCR. We also performed clustering analysis to classify NPC patient groups in terms of EBV gene expression, which presented two subtypes of NPC samples. Results revealed interesting patterns of EBV gene expression in NPC patients. This clustering was correlated with many signaling pathways, such as those related to heterotrimeric G-protein signaling, inflammation mediated by chemokine and cytokine signaling, ribosomes, protein metabolism, influenza infection, and ECM-receptor interaction. Our combined findings suggested that the expression of EBV genes in NPC is restricted not only to type II latency genes but also to type III latency and lytic genes. This study provided further insights into the potential role of EBV in the development of NPC.

癌细胞分离是癌症诊断和治疗的理想手段。除了生化方法,工程化平台是根据癌细胞响应周围微环境物理变化的独特特性将癌细胞与正常细胞分离的有效选择。本研究根据精确控制的设计参数(包括刚度、层数和结构布局),开发了三维(3D)仿生支架平台,用于分离鼻咽癌(NPC43)细胞与永生化鼻咽上皮(NP460)细胞。支架平台上NPC43细胞和NP460细胞的迁移特征表明,NPC43细胞可以挤进10 µm宽、15 µm深的沟槽,而NP460细胞不能。迁移行为的不同主要是由细胞与周围微环境的交互作用不同所导致。NPC43细胞具有丝状伪足样突触,而NP460细胞呈片状形态。使用这些3D仿生平台进行研究发现,在较硬的双层支架平台[顶层为40/10 μm沟脊/沟槽(R/T)栅格,底层为20/10 μm R/T网格]上,NPC43细胞与NP460细胞的分离效率可达89%。此外,通过添加活性条件培养基(ACM)可使细胞具有更高的运动性和变形性,从而将分离效率进一步提高到93%。这些结果表明,研究人员可以利用设计适当的仿生工程化平台分离癌细胞和正常细胞,从而辅助实现癌症诊断和治疗。

Hypoxia is a common phenomenon in hepatocellular carcinoma (HCC). Hypoxia stabilizes transcription factor, hypoxia-inducible factor (HIF), to activate gene transcription. Expression of HIF is closely associated with metastasis and poor prognosis in HCC. HIF mediates expression of genes that are involved in every step of HCC metastasis including epithelial-mesenchymal transition, invasion of the extracellular matrix, intravasation, extravasation, and secondar y growth of the metastases. Because HIF is the central regulator of HCC metastasis, HIF inhibitors are attractive tools when used alone or as combined treatment to curb HCC metastasis. This review will summarize the current findings on the impact of hypoxia/HIF in HCC, with a particular focus on cancer metastasis.

In this review, we summarize the novel findings from our series of studies on the leading metastasis-related gene, osteopontin (OPN). In our previous gene expression profiling study, OPN was identified as one of the leading genes associated with the metastasis of hepatocellular carcinoma (HCC). We focused on OPN to evaluate its prognostic values and important roles in HCC metastasis. A retrospective study of large cohorts of HCC patients demonstrated that plasma OPN level was one of the leading independent prognostic factors for HCC patients, even in the early stage of HCC, and could serve as a surrogate serologic biomarker for monitoring the treatment response and tumor recurrence after HCC resection. Using both in vitro and in vivoinvestigations, we found that OPN has an important role in metastasis and tumor growth of HCC and is an attractive potential therapeutic target for combating HCC metastasis. We also found that OPN+ HCC cells have much more amplifications at chromosomal regions, and promoter polymorphisms are important in the regulation of OPN expression and tumor growth and lung metastasis of HCC.

Hepatocellular carcinoma (HCC) is currently the fifth most common malignancy and the third leading cause of cancer-related mortalities worldwide. In the last few years, treatments for HCC have significantly improved from a mere surgical resection to a series of minimally invasive therapies and targeted drugs. However, recurrence frequently occurs even upon curative therapeutics, and drug therapies generally produce disappointing results, with the overall prognosis dismal. This challenging clinical scenario warrants new effective and life-prolonging strategies for patients with HCC. Compelling evidence suggests that NK cells play a critical role in the immune function of the liver and in the immune defenses against HCC, indicating that HCC might be an ideal target for NK cell-based immunotherapies. To obtain comprehensive insights into the putative influence of NK cells on HCC, this paper summarizes current knowledge on NK cells in HCC and discusses the usefulness and prospects of NK cell-based immunotherapies. Critical issues that require consideration for the successful clinical translation of NK cell-based therapies are also addressed. If appropriately used and further optimized, NK cell-based therapies could dominate important roles in the future immunotherapeutic market of HCC.

Primary hepatic carcinoma (PHC) is a common malignant tumor in China. Cancer is comprehensively treated with various therapeutic regimes, including traditional Chinese medicine (TCM). TCM has been widely used to improve the quality of life, delay the time of cancer progression, and prolong the median survival time. This systematic review with meta-analysis aimed to assess the effect of TCM combined with Western therapy on primary hepatic carcinoma. A comprehensive literature search was conducted in six databases, including CNKI, VIP, Wan-Fang Database, CBM, PubMed, and Cochrane library. A total of 44 randomized controlled trials (RCTs) involving 3429 participants suffering from PHC were selected. Meta-analysis results indicated that the overall effect of TCM and Western integrative treatment on PHC was higher than that of Western intervention alone, which can postpone tumor recurrence and metastasis and prolong the overall survival time of patients with PHC. Although the obtained evidence remained weak because of the poor methodological quality of the included studies, this review provided relevant data supporting the efficacy and safety of TCM combined with Western therapies. In future research, individual RCT studies should incorporate accepted standards for trial design and reporting, proper outcome indicators according to international standards, blinding in allocation concealment, and valid follow-up periods.

We performed weighted gene coexpression network analysis (WGCNA) to gain insights into the molecular aspects of hepatocellular carcinoma (HCC). Raw microarray datasets (including 488 samples) were downloaded from the Gene Expression Omnibus (GEO) website. Data were normalized using the RMA algorithm. We utilized the WGCNA to identify the coexpressed genes (modules) after non-specific filtering. Correlation and survival analyses were conducted using the modules, and gene ontology (GO) enrichment was applied to explore the possible mechanisms. Eight distinct modules were identified by the WGCNA. Pink and red modules were associated with liver function, whereas turquoise and black modules were inversely correlated with tumor staging. Poor outcomes were found in the low expression group in the turquoise module and in the high expression group in the red module. In addition, GO enrichment analysis suggested that inflammation, immune, virus-related, and interferon-mediated pathways were enriched in the turquoise module. Several potential biomarkers, such as cyclin-dependent kinase 1 (CDK1), topoisomerase 2α (TOP2A), and serpin peptidase inhibitor clade C (antithrombin) member 1 (SERPINC1), were also identified. In conclusion, gene signatures identified from the genome-based assays could contribute to HCC stratification. WGCNA was able to identify significant groups of genes associated with cancer prognosis.

Primary neuroendocrine breast carcinoma (NEBC) is a very rare type of breast cancer. Two characteristic biomarkers, namely, CgA and Syn, should be immunohistochemically detected to diagnose NEBC. In this study, a 43-year-old woman with a large mass of 8.3 cm × 2.9 cm in her right breast was reported. The patient was pathologically diagnosed with NEBC after specific markers, including CgA and Syn, as well as few differential markers, such as CK7, ER, PR, C-erbB-2, NSE, and E-cadherin, were immunohistochemically detected. The patient showed a remarkable response to four cycles of neo-adjuvant chemotherapy (partial response based on RECIST criteria) and sequentially underwent modified radical mastectomy. Moreover, the diagnosis and treatment of NEBC based on this case and available related literature were discussed.d literature were discussed.
