DKK1 as a chemoresistant protein modulates oxaliplatin responses in colorectal cancer.
Article in Oncogenesis, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Oxaliplatin is effective against colorectal cancer (CRC), but resistance hampers treatment. We found upregulated Dickkopf-1 (DKK1, a secreted protein) in oxaliplatin-resistant (OR) CRC cell lines and DKK1 levels increased by more than 2-fold in approximately 50% of oxaliplatin-resistant CRC tumors. DKK1 activates AKT via cytoskeleton-associated protein 4 (CKAP4, a DKK1 receptor), modulating oxaliplatin responses in vitro and in vivo. The leucine zipper (LZ) domain of CKAP4 and cysteine-rich domain 1 (CRD1) of secreted DKK1 are crucial for their interaction and AKT signaling. By utilizing the LZ protein, we disrupted DKK1 signaling, enhancing oxaliplatin sensitivity in OR CRC cells and xenograft tumors. This suggests that DKK1 as a chemoresistant factor in CRC via AKT activation. Targeting DKK1 with the LZ protein offers a promising therapeutic strategy for oxaliplatin-resistant CRC with high DKK1 levels. This study sheds light on oxaliplatin resistance mechanisms and proposes an innovative intervention for managing this challenge.
