Oxidative Metabolism Drives Immortalization of Neural Stem Cells during Tumorigenesis

Researchers demonstrated that metabolic reprogramming induced by mitochondrial fusion was rate-limiting for immortalization of tumor-initiating cells and triggered their irreversible dedication to tumorigenesis.

Glioma-Initiating Cells at Tumor Edge Gain Signals from Tumor Core Cells to Promote Their Malignancy

Scientists established regionally derived models of glioblastoma edge and core that retained their spatial identity in a cell autonomous manner.

Cancer Immunotherapy via Targeting Cancer Stem Cells Using Vaccine Nanodiscs

Researchers presented a novel approach to target and reduce the frequency of aldehyde dehydrogenase (ALDH)high CSCs by vaccination against ALDH.

AbstractGraphical Abstract

Engineered Biomimetic Nanoparticle for Dual Targeting of the Cancer Stem-Like Cell Population in Sonic Hedgehog Medulloblastoma

Investigators demonstrated the dual-targeted delivery and enhanced therapeutic effect of eHNP-A1-CD15-LDE225 via scavenger receptor class B type 1 and CD15 on brain sonic hedgehog subtype of medulloblastoma cells in vitro, ex vivo, and in vivo.

The Stress-Like Cancer Cell State Is a Consistent Component of Tumorigenesis

Scientists found that the stress-like subpopulation of cancer cells was present from the early stages of tumorigenesis.

AbstractGraphical Abstract

Hypoxia Triggers the Intravasation of Clustered Circulating Tumor Cells

When dynamically labeling breast cancer cells along cancer progression, investigators observed that the majority of circulating tumor cells (CTCs) clusters undergone hypoxia, while single CTCs were largely normoxic.

Crosstalk between Hedgehog Pathway and the Glucocorticoid Receptor Pathway as a Basis for Combination Therapy in T-Cell Acute Lymphoblastic Leukemia

Researchers presented a therapeutically relevant crosstalk between Hedgehog signaling and the glucocorticoid receptor pathway acting at the level of GLI1 transcription factor.
[Oncogene]

Abstract

Upregulation of CPT1A Is Essential for the Tumor-Promoting Effect of Adipocytes in Colon Cancer

The authors demonstrated that carnitine palmitoyltransferase I (CPT1A), a key enzyme controlling fatty acid oxidation, was upregulated in colon cancer cells upon exposure to adipocytes or fatty acids.

Linc-RA1 Inhibits Autophagy and Promotes Radioresistance by Preventing H2Bub1/USP44 Combination in Glioma Cells

Scientists identified a mechanism of radioresistance mediated by linc-RA1 (radioresistance-associated long intergenic noncoding RNA 1). Linc-RA1 was upregulated in radioresistant glioma cells and glioma tissue samples, compared with radiosensitive cells and nontumor tissues.

Galectin-3 in Prostate Cancer Stem-Like Cells Is Immunosuppressive and Drives Early Metastasis

Investigators showed that prostate cancer stem-like cells also colonizing prostate-draining lymph nodes of transgenic adenocarcinoma of the mouse prostate mice overexpressed galectin 3.

A Mathematical Model of Average Dynamics in a Stem Cell Hierarchy Suggests the Combinatorial Targeting of Cancer Stem Cells and Progenitor Cells as a Potential Strategy against Tumor Growth

Researchers hypothesized that tumor relapse after the selective targeting of CSCs was due to intermediate progenitor cells that maintained the tumor volume. In order to support this hypothesis, they implemented a mathematical model derived using pseudo-reactions representing the events of each cell subpopulation within the tumor.

Long Non-Coding RNA SNHG3, Induced by IL-6/STAT3 Transactivation, Promotes Stem Cell-Like Properties of Gastric Cancer Cells by Regulating the miR-3619-5p/ARL2 Axis

Scientists clarified the potential involvement of long non-coding RNA SNGH3 in the acquisition of cisplatin resistance and stemness in gastric cancer.

Epigenomic Reprogramming as a Driver of Malignant Glioma

The authors describe key chromatin regulatory pathways disrupted in gliomas, delineating their physiological function and the current understanding of how their dysregulation may contribute to gliomagenesis.

Abstract

Co-Targeting of Lysosome and Mitophagy in Cancer Stem Cells with Chloroquine Analogues and Antibiotics

Investigators provide a sketch of the inhibiting roles of current chloroquine analogues and antibiotic combination in CSC autophagy process and discuss the possibility that pre‐clinical and clinical potential therapeutic strategy for anticancer therapy.

Dual Effects of Non-Coding RNAs (ncRNAs) in Cancer Stem Cell Biology

The authors discuss the multifaceted contribution of microRNAs, long non-coding RNAs, and circular RNAs, as representative ncRNA classes, in sustaining the CSC-like traits, as well as the underlying molecular mechanisms of their action in various CSC types.
