Aims: Sex-determining region of Y chromosome-related high-mobility-group box 15 (SOX15) has recently emerged as a candidate tumor-inhibitor in multiple types of human tumors. To date, the involvement of SOX15 in glioma is undetermined. The purpose of this study was to investigate the expression, function and potential molecular mechanism of SOX15 in glioma.
Main Methods: Relative mRNA expression was analyzed by real-time quantitative PCR. Protein expression was determined by Western blot. Cell proliferation was assessed by cell counting kit-8 and colony formation assay. Cell invasion was evaluated by Matrigel invasion assay. Wnt/β-catenin activation was monitored by luciferase reporter assay.
Key Findings: SOX15 expression was decreased in glioma tissues and cell lines compared with normal controls. Kaplan-Meier analysis revealed that patients with low expression of SOX15 had shorter survival than those who had high expression of SOX15. The upregulation of SOX15 markedly repressed the proliferation and invasion of glioma cells, whereas its depletion enhanced glioma cell proliferation and invasion. Research into the mechanism revealed that SOX15 exerted an inhibitory effect on Wnt/β-catenin signaling in glioma cells. Notably, overexpression of β-catenin partially reversed the SOX15 overexpression-mediated tumor-suppressive effect. In addition, SOX15 overexpression significantly impeded tumor formation by glioma cells in vivo in a mouse xenograft model associated with downregulation of active β-catenin expression.
Significance: These data demonstrate that SOX15 functions as a potential tumor-suppressor in glioma by inhibiting cell proliferation and invasion via the downregulation of Wnt/β-catenin signaling.

Objective: The objective of this study is to examine the impact of KW-2478 combined with DDP on colorectal cancer cells both in vitro and in vivo and to elucidate the molecular mechanism of KW-2478 in colorectal cancer.
Methods: qRT-PCR and Western blot were employed to assess HSP90 mRNA and protein expression in normal intestinal epithelial and colorectal cancer cells. DLD-1 and HCT116 were selected for the experiment.

Introduction/objective: Plants and their bioactive compounds play a crucial role in the pharmaceutical industry for treating cancer. To date, the cytotoxic and antiproliferative effects of Hypericum perforatum methanol extract on human thyroid cancer cell lines have not been thoroughly explored. The present study aimed to assess the potential anti-cancer effects of HPME on human thyroid cancer and investigate its potential therapeutic benefits.

-acetyltransferase 10 (NAT10) is a nucleolar acetyltransferase with an acetylation catalytic function and can bind various protein and RNA molecules. As the N4-acetylcytidine (ac4C) "writer" enzyme, NAT10 is reportedly involved in a variety of physiological and pathological activities. Currently, the NAT10-related molecular mechanisms in various cancers are not fully understood.

Flatworms depend on stem cells for continued tissue growth and renewal during their life cycles, making these cells valuable drug targets. While neoblasts are extensively characterized in the free-living planarian , and similar stem cells have been characterized in the trematode , their identification and characterization in cestodes is just emerging. Since stem cells are generally affected by irradiation, in this work we used this experimental approach to study the stem cells of the model cestode .

Introduction: Schistosomiasis has for many years relied on a single drug, praziquantel (PZQ) for treatment of the disease. Immense efforts have been invested in the discovery of protein kinase (PK) inhibitors; however, given that the majority of PKs are still not targeted by an inhibitor with a useful level of selectivity, there is a compelling need to expand the chemical space available for synthesizing new, potent, and selective PK inhibitors. Small-molecule inhibitors targeting the ATP pocket of the catalytic domain of PKs have the potential to become drugs devoid of (major) side effects, particularly if they bind selectively.
