Nanocomplexes loaded with miR-128-3p for enhancing chemotherapy effect of colorectal cancer through dual-targeting silence the activity of PI3K/AKT and MEK/ERK pathway.

Nanocomplexes loaded with miR-128-3p for enhancing chemotherapy effect of colorectal cancer through dual-targeting silence the activity of PI3K/AKT and MEK/ERK pathway. Drug Deliv. 2020 Dec;27(1):323-333 Authors: Liu X, Dong C, Ma S, Wang Y, Lin T, Li Y, Yang S, Zhang W, Zhang R, Zhao G Abstract Although microRNAs (miRNAs)-based cancer therapy strategies have been proved to be efficient and superior to chemotherapeutic agents in certain extent, the unstable properties of miRNAs significantly impaired the wide application. Therefore, how to safely deliver the miRNAs to the targeted site of action is the most pivotal step to achieve the ideal treatment effect. In the present work, the miR-128-3p, which is able of inducing chromosomal instability, was loaded into the nanocomplexes developed by the PEG-PDMAEMA (PDMAEMA-NP). By this way, the miR-128-3p was shielded from exposure to various degrading enzymes in bloodstream. Additionally, the PEGylation endowed the PDMAEMA-NP with long time of circulation as demonstrated in vivo by pharmacokinetics investigation. To target and deliver the miR-128-3p to the site of action, a tumor-homing peptide CPKSNNGVC, which specifically targets the monocarboxylate transporter 1 (MCT1), was decorated on the surface of PDMAEMA-NP. Both in vitro and in vivo experiments demonstrated that more efficient delivery of miR-128-3p to cells or tumor tissues was obtained by the PDMAEMA-NP than plasmid. Additionally, modif...

The role of granulocyte colony‑stimulating factor in breast cancer development: A review. Mol Med Rep. 2020 Mar 10;: Authors: Liu L, Liu Y, Yan X, Zhou C, Xiong X Abstract Granulocyte‑colony‑stimulating factor (G‑CSF) is a member of the hematopoietic growth factor family that primarily affects the neutrophil lineage. G‑CSF serves as a powerful mobilizer of peripheral blood stem cells and recombinant human G‑CSF (rhG‑CSF) has been used to treat granulocytopenia and neutropenia after chemotherapy for cancer patients. However, recent studies have found that G‑CSF plays an importa...

Conclusions: An increasing trend in the number of CRC patients mostly at stage III and IV was found. Our results emphasized that an improvement in CRC survival could be achieved through the adoption of advanced cancer therapies, as well as improved access to quality diagnosis and timely treatment.

ConclusionsThe occurrence of CRCI during the course of treatment in people with different types of cancer is frequent. Some risk factors have been identified, but CRCI is a complex phenomenon, with mediating factors related to cancer and treatment and moderating factors related with lifestyle and health.Implications for Cancer SurvivorsThis review highlights the importance of recognizing that this cognitive dysfunction is frequent, mild to moderate in nature but with great impact on quality of life.

etti Luisa Bracci The development of selective tumor targeting agents to deliver multiple units of chemotherapy drugs to cancer tissue would improve treatment efficacy and greatly advance progress in cancer therapy. Here we report a new drug delivery system based on a tetrabranched peptide known as NT4, which is a promising cancer theranostic by virtue of its high cancer selectivity. We developed NT4 directly conjugated with one, two, or three units of paclitaxel and an NT4-based nanosystem, using NIR-emitting quantum dots, loaded with the NT4 tumor-targeting agent and conjugated with paclitaxel, to obtain a NT4-QD-P...

Abstract Chemotherapy induces inevitable adverse effects, while complementary and alternative medicine employs many chemical substances. Herb pairs normally contain two herbal medicines, and they have satisfactory effects on cancer therapy. Zuojinwan, a well-known herb pair, is composed of Coptidis Rhizoma and Euodiae Fructus. Berberine and evodiamine are considered the most important compounds in the Zuojinwan herb pair. Previous reports have shown that combined use of evodiamine and berberine displays synergistic anticancer activities in various types of cancers, but this combination has not been tested in color...

CONCLUSION: Our data show that fluorouracil-based adjuvant chemotherapy does not work for dMMR cases, if not worse. Autophagy inhibition and/or immune checkpoint inhibition might be promising alternative strategies for gastric cancer treatment. IMPLICATIONS FOR PRACTICE: The use of microsatellite instability (MSI) and mismatch repair (MMR) as predictive biomarkers for adjuvant chemotherapy in colorectal cancer has caused a paradigm shift in cancer therapy, although its implications in gastric cancer are still questionable. The data obtained in the current study indicate that MSI-MMR is an independent prognostic factor...

AbstractThe previous reports have established a strong link between diet, lifestyle, and gut microbiota population with the onset of the colorectal cancer (CRC). Administration of probiotics has become a particular interest in prevention and treatment of CRC. As potential dietary complements, probiotics might be able to lower the risk of CRC and manage the safety of traditional cancer therapies such as surgery, radiation therapy, and chemotherapy.
