CASC2 modulates glioma growth and resistance to temozolomide (TMZ), one of the most commonly used chemotherapeutic agents for glioma, by upregulating the expression of phosphatase and tensin homolog (PTEN), a known tumor suppressor involving in several cancers including gliomas and inhibits Akt signaling pathway and p-Akt pathway via direct inhibition of miR‐181a [27]. This evidence concerns the gene AKT1 and central nervous system cancer.
