Connector enhancer of kinase suppressor of ras 1 mRNA (CNKSR1 mRNA)

Connector enhancer of kinase suppressor of ras 1 (CNKSR1) mRNA is the transcript encoding the CNKSR1 scaffolding protein, which plays a critical role in mediating signal transduction within the RAS/MAPK and PI3K/AKT pathways [1][2]. CNKSR1 acts as a molecular bridge, facilitating the interaction between KRAS and its downstream effectors, making it an essential component for the growth and survival of KRAS-mutant cancer cells [3]. Because direct inhibition of KRAS has historically proven challenging, targeting the CNKSR1 mRNA using antisense oligonucleotides (ASOs) has emerged as a strategic approach to deplete the protein and disrupt oncogenic signaling [4]. Preclinical studies have demonstrated that reducing CNKSR1 mRNA levels leads to decreased tumor cell proliferation and increased apoptosis in aggressive malignancies such as pancreatic and non-small cell lung cancers [2][5]. By specifically targeting the mRNA transcript, these therapeutic strategies aim to bypass the difficulties of drugging protein-protein interaction sites on the scaffold itself [4].
