Biological functions and clinical applications of exosomal non-coding RNAs in hepatocellular carcinoma.

Biological functions and clinical applications of exosomal non-coding RNAs in hepatocellular carcinoma. Cell Mol Life Sci. 2019 Jul 12;: Authors: Li C, Xu X Abstract Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide, with a high mortality rate. Its dismal prognosis is attributed to late diagnosis, high risk of recurrence and drug resistance. To improve the survival of patients with HCC, new approaches are required for early diagnosis, real-time monitoring and effective treatment. Exosomes are small membranous vesicles released by most cells that contain biological molecules and play a great role in intercellular communication under physiological or pathological conditions. In cancer, exosomes from tumor cells or non-tumor cells can be taken up by neighboring or distant target cells, and the cargoes in exosomes are functional to modulate the behaviors of tumors or reshape tumor microenvironment (TME). As essential components, non-coding RNAs (ncRNAs) are selectively enriched in exosomes, and exosomal ncRNAs participate in regulating specific aspects of tumor development, including tumorigenesis, tumor metastasis, angiogenesis, immunomodulation and drug resistance. Besides, dysregulated exosomal ncRNAs have emerged as potential biomarkers, and exosomes can serve as natural vehicles to deliver tumor-suppressed ncRNAs for treatment. In this review, we briefly summarize the biology of exosomes, the functions of exosomal ncRNAs in...

Authors: Song X, Du R, Gui H, Zhou M, Zhong W, Mao C, Ma J Abstract Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer‑related deaths among cancer patients. Genes correlated with the progression and prognosis of HCC are critically needed to be identified. In the present study, 3 Gene Expression Omnibus (GEO) datasets (GSE46408, GSE65372 and GSE84402) were used to analyze the differentially expressed genes (DEGs) between HCC and non‑tumor liver tissues. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted to clarify the functional roles of DEG...

LncRNA ROR1‑AS1 high expression and its prognostic significance in liver cancer. Oncol Rep. 2019 Nov 04;: Authors: Zhang Z, Wang S, Yang F, Meng Z, Liu Y Abstract Hepatocellular carcinoma (HCC) is a common disease of the digestive system with no curative treatments. Long noncoding RNA tyrosine protein kinase transmembrane receptor 1 antisense RNA 1 (lncRNA ROR1‑AS1) is an lncRNA whose functions have been predicted in human diseases; however, its important role in cancer has been probed only in mantle cell lymphoma, not in HCC. Therefore, the present study aimed to elucidate the prognostic...

Hypoxia‑inducible factors in hepatocellular carcinoma (Review). Oncol Rep. 2019 Nov 01;: Authors: Guo Y, Xiao Z, Yang L, Gao Y, Zhu Q, Hu L, Huang D, Xu Q Abstract Maintenance of an appropriate oxygen concentration is essential for the function of the liver. However, in many pathological conditions, and particularly in the tumor microenvironment, cells and tissues are frequently in a hypoxic state. In the presence of hypoxia, the cells adapt to the low oxygen levels through the hypoxia‑inducible factor (HIF) pathway. Overgrowth of tumor cells restricts the diffusion of oxygen in tumors, leading to ...

Authors: Zan Y, Dai Z, Liang L, Deng Y, Dong L Abstract Sorafenib (SOR) is a multi-kinase inhibitor that was approved as the first-line systematic treatment agent of hepatocellular carcinoma (HCC). However, the anti-cancerous effect of SOR is dramatically impaired by the drug resistance, insufficient accumulation at tumor tissues, and limited tumor inner penetration. To combat the above issues, the PLA-based nanoparticles were first fabricated and co-loaded with SOR and plantamajoside (PMS), natural herbal medicines that possess excellent anti-cancerous effect on many types of drug resistant cancers. Then, the poly...

In this study, we evaluate complete blood count based inflammatory markers in hepatocellular carcinoma (HCC) to predict overall and recurrence-free survival of patients after liver transplant. Between 2001 and 2017, all HCC indicated liver transplants were retrospectively reviewed. Inclusion criteria included presence of complete blood cell counts with differential within three months prior to transplantation. Exclusion criteria included retransplantation and inadequate posttransplant followup. A total of 160 patients with HCC were included in the study. Of those, 74.4% had hepatitis C virus as the underlying cause of HCC....

monte Buonaguro Cancer genome instability leads to accumulation of mutations which may result into tumor-specific mutated “neoantigens”, not be affected by central T-cell tolerance. Such neoantigens are considered the optimal target for the patient’s anti-tumor T cell immunity as well as for personalized cancer immunotherapy strategies. However, only a minor fraction of predicted neoantigens are relevant to the clinical outcome. In the present study, a prediction algorithm was applied using datasets of RNA sequencing from all 377 Hepatocellular carcinoma (HCC) patients available at The ...

ery Both non eco- and eco-friendly carriers were utilized for accelerating the dyeing rate of polyethylene terephthalate fabrics (PET) dyed with disperse dyes at 100 °C. Fastness properties of the dyed fabrics showed good and excellent results. Finally, the prepared disperse dyes 1 and 2 showed potent anti-tumor cytotoxic activity in vitro using MCF-7 cells (human breast cancer cell line), HepG-2 cells (human Hepatocellular carcinoma), HCT-116 (colon carcinoma), A-549 cells (Lung carcinoma cell line), and anti-oxidant activities.

CONCLUSIONS: Our studies demonstrated that GLO1 was highly expressed in glioma tissues and significantly correlated with the poor prognosis of glioma patients. It indicated that GLO1 might serve as a new prognostic predictor and therapeutic target for glioma treatment. PMID: 31738028 [PubMed - as supplied by publisher]
