Bufalin-Loaded CaP/DPPE-PEG-EGF Nanospheres: Preparation, Cellular Uptake, Distribution, and Anti-Tumor Effects.

Bufalin has significant antitumor effects on various kinds of tumors. However, bufalin's clinical utility is severely limited because of its side effects, toxicity, and fast metabolism. We made bufalin-loaded, targeted nanospheres with the aim of overcoming bufalin's limitations.

microRNA-497 inhibits invasion and metastasis of colorectal cancer cells by targeting vascular endothelial growth factor-A.

Objectives: microRNAs (miRNAs), are non-coding RNAs that regulate gene expression, and are involved in tumour development. The aim of this study was to investigate microRNA-497 (miR-497) expression and its role in development of colorectal cancer (CRC).

Materials And Methods: RT-PCR was performed to detect expression of miR-497 in CRC cell lines (HCT8, LOVO, Ls-174, HCT116 and HT29) and in clinical cancer specimens.

Effect of Auricular Acupressure on Uremic Pruritus in Patients Receiving Hemodialysis Treatment: A Randomized Controlled Trial.

Background. Uremic pruritus (UP) is a common symptom in patients undergoing maintenance hemodialysis for end-stage renal disease (ESRD). Objective.

Anti-angiogenic and anti-proliferative effects of inhibition of HIF-1α by p-HIF-1α RNAi in colorectal cancer.

The aim of this study was to construct an RNA-interference plasmid (p-HIF-1α RNAi) targeting the human HIF-1α gene and assess its effects on HIF-1α expression and its anti-tumour functions in vitro. p-HIF-1α RNAi was constructed and confirmed by polymerase chain reaction (PCR) and DNA sequencing. Reverse transcriptase PCR (RT-PCR) and western blot were performed to detect HIF-1α expression in HCT116 cells following transfection of p-HIF-1α RNAi and p-control.

Preparation of bufalin-loaded pluronic polyetherimide nanoparticles, cellular uptake, distribution, and effect on colorectal cancer.

A large number of studies have shown that bufalin can have a significant antitumor effect in a variety of tumors. However, because of toxicity, insolubility in water, fast metabolism, short half-life, and other shortcomings, its application is limited in cancer therapy. In this study, we explored the anti-metastatic role of bufalin-loaded pluronic polyetherimide nanoparticles on HCT116 colon cancer-bearing mice.

Golgi phosphoprotein 2 down-regulates the Th1 response in human gastric cancer cells by suppressing IL-12A.

Golgi phosphoprotein 2 (GOLPH2) is a very important biomarker in a variety of diseases. Its biological function is not clear, particularly in gastric cancer. To investigate the role of GOLPH2 in human gastric cancer, and determine its effect on the Th1 lymphocyte response, its expression and that of IL-12A were measured by real-time PCR and immunohistochemistry.

Mitochondrial translocation of cofilin-1 promotes apoptosis of gastric cancer BGC-823 cells induced by ursolic acid.

The pathogenesis of gastric cancer is characterized by excessive proliferation, abnormal differentiation, and reduced apoptosis. Ursolic acid, extracted from traditional Chinese medicine bearberry, inhibits cell growth and induces apoptosis in gastric cancer. However, the mechanism of the proapoptotic effect of ursolic acid on gastric cancer cells needs further investigation.
