Controlled Secretion of the Anticancer Protein MDA-7 from Engineered Mesenchymal Stem Cells.

Mesenchymal stem cells (MSCs) have been explored as a "live" carrier of cytokines for targeted cancer therapy, but, in earlier reports in the literature, the secretion process of therapeutic cytokines was not regulated. The purpose of this study was to generate MSCs to conditionally secrete the melanoma differentiation-associated gene-7 (MDA-7) tumor-suppressor protein. To control the secretion of MDA-7 from MSCs, a well-established tetracycline-controlled transcriptional activation system was incorporated into MDA-7 plasmid.

Endocan as a prognostic biomarker of triple-negative breast cancer.

Purpose: Triple-negative breast cancer (TNBC) has aggressive characteristics and fewer treatment options than other subtypes. The purpose of this study was to explore prognostic biomarkers for TNBC that can be easily detected from the blood samples.

Methods: MDA-MB-231 and MDA-MB-231BR, a brain metastatic variant of the human TNBC cell line MDA-MB-231, were used as less and more aggressive models of TNBC, respectively.

Multiple Infarcts Are Associated With Long-Term Stroke Recurrence and All-Cause Mortality in Cryptogenic Stroke Patients.

Background And Purpose: Brain infarct patterns that are observed via diffusion-weighted imaging are useful for classifying stroke subtypes. However, it is unclear whether infarct patterns can predict long-term outcomes in cryptogenic stroke patients. Herein, we investigated the association between acute brain infarct patterns and long-term stroke outcomes in cryptogenic stroke patients.
