KHOS-240S Cells

KHOS-240S is an osteosarcoma cell line that is derived from human bone sarcoma tissue. This cell line, along with its variants, has been extensively used in research focused on osteosarcoma, a primary malignant bone tumor that predominantly affects children and young adults. Osteosarcoma is characterized by the production of immature bone (osteoid) by malignant cells and is notorious for its aggressive behavior and potential for early metastasis, particularly to the lungs. The KHOS-240S cell line is resistant to several kinase inhibitors, including those targeting the PI3K-Akt-mTOR pathway. This resistance to common therapeutic targets makes KHOS-240S particularly valuable for studying the mechanisms of drug resistance in osteosarcoma and exploring alternative therapeutic strategies. Researchers have used this cell line to screen a variety of oncology drugs and investigational agents, which has led to the identification of compounds that could potentially overcome resistance mechanisms. The expression profile of genes associated with drug resistance and osteosarcoma biology, such as those involved in the mTOR signaling pathway, is of particular interest in studies utilizing KHOS-240S. Moreover, KHOS-240S has been utilized in the exploration of microRNA expression patterns, which may correlate with drug sensitivity or resistance. This cell line?s specific resistance to PI3K-Akt-mTOR pathway inhibitors provides an essential model for understanding how osteosarcomas may evade targeted therapies and offers a basis for the development of novel therapeutic approaches that could enhance treatment efficacy in resistant osteosarcoma subtypes.
