Gold nano-particles (AuNPs) carrying miR-326 targets PDK1/AKT/c-myc axis in hepatocellular carcinoma.

Gold nano-particles (AuNPs) carrying miR-326 targets PDK1/AKT/c-myc axis in hepatocellular carcinoma. Artif Cells Nanomed Biotechnol. 2019 Dec;47(1):2830-2837 Authors: Mo Y, He L, Lai Z, Wan Z, Chen Q, Pan S, Li L, Li D, Huang J, Xue F, Che S Abstract Abnormal expression of microRNAs (miRNAs) contributes to tumour growth and invasion. MiR-326 expression often down-regulates in several kinds of cancer and low expression of miR-326 is linked with poor prognosis in cancer patients. In the present study, we aimed to explore the modulatory mechanism of miR-326 in hepatocellular carcinoma (HCC). miR-326 expression was significantly decreased in HCC cell lines and tissues. miR-326 decreased HCC cell growth by affecting cell-cycle progression and by promoting apoptosis. In addition, miR-326 inhibited HCC cell invasion by decreasing the EMT phenotype. We found that miR-326 functioned as a tumour suppressor by repressing its down-stream target PDK1. C-myc contributed to miR-326 down-regulation through binding at its promoter and inhibited its expression. Based on these results, we conducted a therapeutic experiment by using gold nano-particles (AuNPs) carrying miR-326. Restoration of miR-326 reduced tumour growth in vivo. Our findings suggest that miR-326 may be a candidate prognostic biomarker and a target for new therapies in HCC patients. PMID: 31298047 [PubMed - in process]

Thus, national guidelines for the pertinent draft, and recommendations of PBT for cancer patients are utmost important. Saudi Particle Therapy Centre invited a panel of expert radiation oncologists practicing within KSA to formulate national clinical practice guidelines for the referral, absolute and relative indications and dose/fractionation for PBT. After identifying the key clinical...

However, the clinical use of zinc(II) complexes is hampered by hydrolytic insolubility and poor bioavailability and their anticancer mechanisms remain unclear. Here, we investigated the efficacy and mechanism of action of a polyvinylpyrrolidone (PVP-k30)-based solid dispersion of Zn(II)-curc...

LncRNA AWPPH participates in the metastasis of non-small cell lung cancer by upregulating TGF-β1 expression. Oncol Lett. 2019 Oct;18(4):4246-4252 Authors: Huo Y, Li A, Wang Z Abstract Long non-coding RNA (lncRNA) AWPPH is a characterized oncogenic lncRNA in hepatocellular carcinoma and bladder cancer. The aim of the present study was to investigate the potential involvement of AWPPH in non-small cell lung cancer (NSCLC). Expression of AWPPH in lung biopsy tissues and serum of both healthy controls and patients with NSCLC with different tumor sizes, and with and without distant tumor metastasis was...

Authors: Yu F, Wang L, Zhang B Abstract Long non-coding RNA (lncRNA) downregulated in hepatocellular carcinoma (DRHC) is a tumor suppressor in liver cancer. However, the role of this lncRNA in breast cancer has not been investigated. The present study revealed that lncRNA DRHC was downregulated and lncRNA Hox transcript antisense RNA (HOTAIR) was upregulated in tumor tissues compared with adjacent healthy tissues in patients with triple negative breast cancer (TNBC). Expression levels of lncRNA DRHC and lncRNA HOTAIR were negatively correlated in tumor tissues but not in adjacent healthy tissues. The lncRNA DRHC ex...

In the present study, gene expression was analyzed using qPCR and western blotting. Glucose uptake was analyzed using a glucose uptake assay and cell proliferation was analyzed using a cell counting kit-8 assay. LINC01638 lncRNA and glucose transporter 1 (GLUT1) were upregulated in tumor tissues compared with adjacent healthy tissues of patients with HCC. Expression levels of LINC01638 lncRNA and G...

In conclusion, the current results revealed a tumor suppressive role of miR-300 in HCC and indicated that the underlying mechanism was associated with a regulation of CREPT. The present study suggests that miR-300 and CREPT may serve as potential therapeutic targets for liver cancer. PMID: 31516587 [PubMed]

ConclusionsPembrolizumab and nivolumab are the only checkpoint inhibitors with data in HCC. Meta-analysis of their effectiveness discloses rates not dissimilar to other systemic therapies available for this disease. Of interest also are the observed long responses in a sub-set of responders. Further development is clearly warranted.
