SP1 and colorectal carcinoma: A 9‐gene prognostic model based on the ELK4‐SP1/3 complex‐regulated gene set showed robust prognostic accuracy. The results demonstrate that ELK4 cooperates with SP1 and SP3 to transcriptionally regulate LRG1 to promote CRC tumorigenesis in an SRF‐independent manner, identifying the ELK4‐SP1/SP3 complex as a potential target for rational combination therapy.
