Glioblastoma multiforme is the most malignant primary intrinsic brain tumor. Glioma stem cells (GSCs) are associated with chemoradiotherapy resistance and the recurrence of glioblastomas after conventional therapy. The targeting of GSCs is potentially an effective treatment for the long-term survival of glioblastoma patients. Licochalcone A, a natural chalconoid from licorice root, exerts anticancer effects; however, its effect on GSCs remains unknown. We found that Licochalcone A induced massive caspase-dependent death in GSCs but not in differentiated GSCs nor normal somatic and neural stem cells. Prior to cell death, Licochalcone A caused mitochondrial fragmentation and reduced the membrane potential and ATP production in GSCs. Thus, Licochalcone A induces mitochondrial dysfunction and shows promise as an anticancer stem cell drug.

Intravenous administration of mitochondria improves ovarian function by anti-apoptosis in the premature ovarian insufficiency model.

Objective: For patients with contraindications to hormone therapy, the absence of effective treatments for ovarian dysfunction post chemotherapy represents a critical issue requiring resolution. Local administration of mitochondria may enhance ovarian function in premature ovarian insufficiency (POI) by ameliorating diminished mitochondrial activity. Nevertheless, there is a paucity of literature on the efficacy of mitochondrial transplantation through intravenous injection, a less invasive and more convenient method than local injection, for the improvement of ovarian function in POI following chemotherapy.

Purpose: Our aim was to examine the expression of PAX6 and keratocyte-specific markers in human limbal stromal cells (LSCs) in congenital aniridia (AN) and in healthy corneas, .
Methods: Primary human LSCs were extracted from individuals with aniridia (AN-LSCs) ( = 8) and from healthy corneas (LSCs) ( = 8). The cells were cultured in either normal-glucose serum-containing cell culture medium (NGSC-medium) or low-glucose serum-free cell culture medium (LGSF-medium).
Tribbles pseudokinase 3 drives cancer stemness in oral squamous cell carcinoma cells by supporting the expression levels of SOX2 and EGFR.

Oral squamous cell carcinoma (OSCC) is a type of head and neck cancer (HNC) with a high recurrence rate, which has been reported to be associated with the presence of cancer stem cells (CSCs). Tribbles pseudokinase 3 (TRIB3) is involved in intracellular signaling and the aim of the present study was to investigate the role of TRIB3 in the maintenance of CSCs. Analysis of The Cancer Genome Atlas database samples demonstrated a positive correlation between TRIB3 expression levels and shorter overall survival rates in patients with HNC.

Many oncoproteins are important therapeutic targets because of their critical role in inducing rapid cell proliferation, which represents one of the salient hallmarks of cancer. Chronic Myeloid Leukemia (CML) is a cancer of hematopoietic stem cells that is caused by the oncogene BCR-ABL1. BCR-ABL1 encodes a constitutively active tyrosine kinase protein that leads to the uncontrolled proliferation of myeloid cells, which is a hallmark of CML.

Background: Gastric cancer has become one of the major diseases threatening human health. This study aimed to investigate the mechanism of an anticancer bioactive peptide (ACBP) combined with oxaliplatin (OXA) on MKN-45, SGC7901, and NCI-N87 differentiated human gastric cancer cells and GES-1 immortalized human gastric mucosal epithelial cells. The therapeutic effect and action mechanism of short-term intermittent ACBP combined with OXA on nude mice with human gastric cancer were also investigated.
