PKA inhibition kills L-asparaginase-resistant leukemic cells from relapsed acute lymphoblastic leukemia patients.
Article in Cell death discovery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Despite the success in treating newly diagnosed pediatric acute lymphoblastic leukemia (aLL), the long-term cure rate for the 20% of children who relapse is poor, making relapsed aLL the primary cause of cancer death in children. By unbiased genome-wide retroviral RNAi screening and knockdown studies, we previously discovered opioid receptor mu 1 (OPRM1) as a new aLL cell resistance biomarker for the aLL chemotherapeutic drug, L-asparaginase, i.e., OPRM1 loss triggers L-asparaginase resistance. Indeed, aLL cell OPRM1 level is inversely proportional to L-asparaginase IC50: the lower the OPRM1 level, the higher the L-asparaginase IC50, indicating that aLL cells expressing reduced OPRM1 levels show resistance to L-asparaginase. In the current study, we utilized OPRM1-expressing and -knockdown aLL cells as well as relapsed patient aLL cells to identify candidate targeted therapy for L-asparaginase-resistant aLL. In OPRM1-expressing cells, L-asparaginase induces apoptosis via a cascade of events that include OPRM1-mediated decline in [cAMP]
