An intratumor bacteria-targeted DNA nanocarrier for multifaceted tumor microenvironment intervention.

Intratumor bacteria, which are involved with complex tumor development mechanisms, can compromise the therapeutic efficiencies of cancer chemotherapeutics. Therefore, the development of anti-tumor agents targeting intratumor bacteria is crucial in overcoming the drug inactivation induced by bacteria colonization. In this study, a double-bundle DNA tetrahedron-based nanocarrier is developed for intratumor bacteria-targeted berberine (Ber) delivery.

FAM46A expression is elevated in glioblastoma and predicts poor prognosis of patients.

Objective: To study the expression of FAM46A in glioblastoma (GBM) and analyze its significance in predicting the prognosis of patients.

Materials And Methods: mRNA expression and clinical data of patients with GBM were retrieved from ONCOMINE databases and The Cancer Genome Atlas (TCGA) database. Immunohistochemistry was performed in a tissue microarray including 110 GBM cases and 12 normal controls to determine the expression of FAM46A protein.

Promotes Malignant Progression of Glioma by Targeting miR-140-5p and Regulating PI3K/AKT Pathway.

Purpose: To explore the regulatory mechanism of long non-coding RNA small nucleolar RNA host gene 1 (SNHG1) in glioma.

Materials And Methods: The expression of SNHG1 and miR-140-5p in glioma tissues and glioma cell lines (LN-18, KNS-81, and KALS-1) was determined, and the effect of the two on cell proliferation, invasion, and PI3K/AKT pathway was analyzed.

Results: SNHG1 was overexpressed in glioma tissues, while miR-140-5p was underexpressed in them, and there was a significant negative correlation between SNHG1 and miR-140-5p.

SLC34A2 promotes neuroblastoma cell stemness via enhancement of miR-25/Gsk3β-mediated activation of Wnt/β-catenin signaling.

Cancer stem cells contribute to cancer progression, but the mechanisms underlying neuroblastoma stem cell development are unclear. Here, we examined the roles of the transcription factor SLC34A2 in regulating the stemness of neuroblastoma cells. We found that SLC34A2 expression was negatively correlated with the overall survival and relapse-free survival probability of neuroblastoma patients.
