Enhancing the therapeutic effect via elimination of hepatocellular carcinoma stem cells using Bmi1 siRNA delivered by cationic cisplatin Nanocapsules
Resistance of hepatocellular carcinoma (HCC) to systemic chemotherapy is partially due to presence of drug-resistant cancer stem cells. Bmi1 protein is essential for survival and proliferation of HCC cancer stem cells (CSCs). Here, we report that Bmi1 siRNA (Bmi1siR) loaded in cationic nanocapsules of cisplatin (NPC) eliminated stem cells in situ HCC in mice. NPC/Bmi1siR was fabricated via electrostatic complexation of Bmi1 siRNA to NPCs, which had cores composed of cisplatin and were coated with cationic lipids.

Poor expression of long-chain noncoding RNA GAPLINC inhibits epithelial–mesenchymal transition, and invasion and migration of hepatocellular carcinoma cells
This study suggests that the high expression of GAPLINC in HCC is an independent risk factor for the prognosis of HCC. Additionally, downregulation of GAPLINC can inhibit the EMT, proliferation, invasion and migration of HCC cells.

SiRNA-targeted carboxypeptidase D inhibits hepatocellular carcinoma growth.
Abstract Carboxypeptidase D (CPD), a membrane-bound metallocarboxypeptidase that functions as a docking receptor for duck hepatitis B virus, is frequently overexpressed in human cancers. We have explored its expression pattern, clinical significance, and biological function of CPD in hepatocellular carcinoma (HCC). CPD expression was markedly elevated in HCCs relative to adjacent non-tumor liver tissues, as determined by quantitative real-time polymerase chain reaction and Western blot analysis. Immunohistochemistry showed that 164 of 400 (41%) HCCs had high expression of CPD. CPD overexpression was significantly ...

The long noncoding RNA, EGFR-AS1, a target of GHR, increases the expression of EGFR in hepatocellular carcinoma
Abstract LncRNA has provided an important new perspective regarding gene regulation. Both the expression and activation of EGFR have been proven to be under the tight control of the GHR pathway. EGFR-AS1 has been found to inhibit the expression of EGFR. GHR-siRNA and EGFR-AS1-siRNA were transfected into HCC cell lines, and a series of WB, q-PCR, and IF experiments was conducted to evaluate whether EGFR-AS1 participated in the regulation of GHR and EGFR. We found that impeded expression of GHR decreased the expression of EGFR and EGFR-AS1 in vivo and in vitro. Then, it was verified that EGFR and EGFR-AS1 were relat...

Targeted silencing of CXCL1 by siRNA inhibits tumor growth and apoptosis in hepatocellular carcinoma.
In conclusion, these findings suggest that CXCL1 plays critical roles in the growth and apoptosis of HCC. RNAi of CXCL1 inhibits the growth and apoptosis of tumor cells, which indicates that CXCL1 may be a potential molecular target for use in HCC therapy.

CD-PLLD co-delivering docetaxel and MMP-9 siRNA plasmid for nasopharyngeal carcinoma therapy in  vivo.
CD-PLLD co-delivering docetaxel and MMP-9 siRNA plasmid for nasopharyngeal carcinoma therapy in vivo. Mol Med Rep. 2017 Jun 07;: Authors: Liu T, Wu X, Wang Y, Hou X, Jiang G, Wu T, Xie H, Xie M Abstract The co-delivery of a drug and a target gene has become a primary strategy in cancer therapy. Based on our previous study, a synthesized star‑shaped co‑polymer consisting of β‑cyclodextrin (CD) and a poly(L‑lysine) dendron (PLLD) was used to co-deliver docetaxel (DOC) and matrix metalloproteinase 9 (MMP‑9) small interfering RNA, via CD‑PLLD/DOC/MMP‑9 complexes, into mice implanted with HN...

Antitumor activity of kinetochore-associated protein 2 siRNA against lung cancer patient-derived tumor xenografts.
Authors: Makita Y, Teratani M, Murata S, Hoashi Y, Matsumoto S, Kawamata Y Abstract It has been widely reported that patient-derived tumor xenografts (PDXs) are more similar to tumor tissues than conventional cancer cell lines. Kinetochore-associated protein 2 (KNTC2) is known to be upregulated specifically in tumor tissues of cancer patients and is recognized as a potential target for cancer therapy. Previously, in vivo antitumor activities of KNTC2 short interfering RNA encapsulated into a lipid nanoparticle (KNTC2-LNP) were reported in orthotopic hepatocellular carcinoma mouse models. However, it remains unclear...

Long non-coding RNA PVT1 regulates the migration of hepatocellular carcinoma HepG2 cells via miR-3619-5p/MKL1 axis.
In this study, we investigated the relationship between PVT1 and MKL1 as a novel regulatory mechanism underlying HCC progression. We used HepG2 and Cos‑7 cell lines. Transfection experiments with miR-3619-5p mimics/inhibitor, PVT1, siRNA-PVT1, MKL1, or siRNA-MKL1 were performed. RNA and protein levels were analyzed by quantitative reverse transcription PCR and Western blot, respectively. Cell migration was assessed by Transwell assay. Luciferase assays, RNA-FISH, RNA immunoprecipitation, and chromatin immunoprecipitation assays were performed to confirm the interaction between PVT1, miR-3619-5p, and MKL1 in HCC cells. Ov...

The Prognostic and Clinical Value of CD44 in Colorectal Cancer: A Meta-Analysis
Conclusions: This meta-analysis demonstrated that CD44 overexpression might be an unfavorable prognostic factor for CRC patients and could be used to predict poor differentiation, lymph node metastasis and distant metastasis. Introduction Although therapies for colorectal cancer (CRC) has improved in recent years, colorectal cancer is still the third most common cause of cancer related death worldwide (1). Metastasis are observed in 25% of patients at initial diagnosis and approximately 50% of patients will develop metastasis (2). Presently, the outcome prediction and the therapy schedule determination of CRC patie...
