Background: Tongue squamous cell carcinoma (SCC) contains a cell subpopulation referred to as cancer stem cells (CSCs), which are responsible for tumor growth, metastasis, and resistance to chemotherapy and radiotherapy. The CSC markers have been used to isolate these cells and as biomarkers to predict overall survival.
Methods: The CSC markers CD44, NANOG, OCT4, and BMI1 were investigated using reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR) and immunohistochemistry and correlated with clinicopathological parameters.
Results: The CD44 overexpression was associated with disease-related death (P = 0.02) and worst prognosis. NANOG was upregulated in nontumoral margins and associated with T1/T2 classification, lymph node metastasis, and worst prognosis. OCT4 was associated with lymph node metastasis and worst overall survival. BMI1 and CD44v3 were overexpressed in tongue SCC. Coexpression of CD44 /NANOG was associated with worst overall survival when compared with patients with CD44 /NANOG .
Conclusion: The CSC markers might play an important role not only in CSC trait acquisition but also in tongue SCC development and progression.

Lymphangioleiomyomatosis (LAM) is a rare lung disease caused by hyperactivation of the mechanistic/mammalian target of rapamycin 1 (mTORC1) growth pathway in a subset of mesenchymal lung cells. Histopathologically, LAM lesions have been described as immature smooth muscle-like cells positive for the immature melanocytic marker HMB45/PMEL/gp100 and phosphorylated ribosomal protein S6 (pS6). Advances in single cell sequencing (scRNA-seq) technology allowed us to group LAM cells according to their expression of cancer stem cell (CSC) genes and identify three clusters: a high CSC-like state (SLS), an intermediate state, and a low CSC-like inflammatory state (IS).

Cancer stem cells (CSCs) are central to tumour initiation, progression, and relapse, yet their dynamic and adaptive nature hampers therapeutic targeting. Once viewed as a fixed subpopulation, CSCs are now recognised as a fluid functional state that tumour cells can enter or exit, driven by intrinsic programs, epigenetic reprogramming, and microenvironmental cues. This plasticity complicates identification due to inconsistent marker expression and enables resistance, dormancy, and metastasis.

Introduction: Fatty acid synthase (FASN) is a key regulator of lipid metabolism, but its role in colorectal cancer (CRC) stemness and ferroptosis remains unclear.
Methods: FASN expression in CRC was analyzed using TCGA data and validated in CRC cell lines (CACO-2, HCT116, SW480) and normal HIEC-6 cells via qRT-PCR and Western blot. HCT116 cells (highest FASN expression) were used for experiments.

Background: Cerebrospinal fluid (CSF) serves an essential role in biomarker research. New Parkinson's disease (PD) classifications incorporate CSF α-synuclein status into trial design. This study evaluated the safety and feasibility of serial CSF collection in participants enrolled in the Parkinson's Progression Markers Initiative (PPMI).

Background: Ovarian cancer (OC) is a highly lethal gynecological malignancy, mainly due to chemoresistance and tumor recurrence. Cancer stem cells (CSCs) may be responsible for chemoresistance, and CSC has become a new target for treatment. In this study, we aimed to develop a three-dimensional (3D) OC model with well-recapitulated stemness in the tumor microenvironment (TME).
