ALKBH5 Suppresses Tumor Progression via an m6A-Dependent Epigenetic Silencing of Pre-miR-181b-1/Yap Signaling Axis in Osteosarcoma

The authors explored the potential involvement of ALKBH5 in osteosarcoma and deciphered the underlying cellular/molecular mechanisms. They discovered downregulated levels of demethylase ALKBH5 were correlated with increased m6A methylation in osteosarcoma cells/tissues compared with normal osteoblasts cells/tissues.

Chitinase-3 Like-Protein-1 Function and Its Role in Diseases

Non-enzymatic chitinase-3 like-protein-1 (CHI3L1) binds to chitin, heparin, and hyaluronic acid, and is regulated by ECM changes, cytokines, growth factors, drugs, and stress. This review summarizes the potential roles and mechanisms of CHI3L1 in oncogenesis and disease pathogenesis, then posits investigational strategies for targeted therapies.

Role of HSP70 in Response to (Thermo)Radiotherapy: Analysis of Gene Expression in Canine Osteosarcoma Cells by RNA-seq

Researchers investigated up- and down-regulated genes in response to (thermo)radiotherapy in HSP70 proficient and deficient canine osteosarcoma cell line, and functional role of HSP70 in the mechanism of thermoradiosensitization.
