doi: 10.1038/s41419-022-05291-w

Figure Lengend Snippet: Left, CHKα mRNA is translated to protein, which promotes the activation of choline metabolism and AKT pathway, thereby promoting the growth and invasion of OC. Right, DHRS2 can directly bind to CHKα mRNA to accelerate its degradation. Correspondingly, CHKα protein expression is downregulated, resulting in the disruption of choline metabolism and AKT signaling. These effects lead to the inhibition of OC growth and metastasis. OC, ovarian cancer.
