Increased CSN5 expression enhances the sensitivity to lenalidomide in multiple myeloma cells.

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
Lenalidomide (LEN) is commonly used as an effective therapeutic agent for multiple myeloma (MM). However, in some patients, primary resistance to LEN is observed, the mechanisms of which remain poorly understood. In this study, we combined a LEN sensitivity assay with proteomics data from 15 MM cell lines to identify protein expression profiles associated with primary LEN resistance. Our findings revealed that CSN5 expression is lower in LEN-resistant cell lines than in LEN-sensitive lines. Moreover, we established that CSN5 is degraded via the cullin-RING ubiquitin ligase (CRL)-mediated ubiquitin-proteasome pathway through ubiquitination at lysine 194. Our data suggest that reduced CSN5 expression leads to abnormalities in the ubiquitination cycle of CRL4A, resulting in the inhibition of LEN-mediated degradation of IKZF1 and IKZF3. These findings delineate an additional mechanism of LEN resistance in MM cells and may contribute to the development of alternative therapeutic strategies to overcome LEN resistance.
