Global functional genomics reveals GRK5 as a cystic fibrosis therapeutic target synergistic with current modulators.
Article in iScience, 2025. 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
Cystic fibrosis (CF) is a life-shortening disease affecting >160,000 individuals worldwide predominantly with respiratory symptoms. About 80% of individuals with CF have the p.Phe508del variant that causes the CF transmembrane conductance regulator (CFTR) protein to misfold and be targeted for premature degradation by the endoplasmic reticulum (ER) quality control (ERQC), thus preventing its plasma membrane (PM) traffic. Despite the recent approval of a "highly effective" drug rescuing p.Phe508del-CFTR, maximal lung function improvement is ∼14%. To identify global modulators of p.Phe508del traffic, we performed a high-content small interfering RNA (siRNA) microscopy-based screen of >9,000 genes and monitored p.Phe508del-CFTR PM rescue in human airway cells. This primary screen identified 227 p.Phe508del-CFTR traffic regulators, of which 35 could be validated by additional siRNAs. Subsequent mechanistic studies established GRK5 as a robust regulator whose inhibition rescues p.Phe508del-CFTR PM traffic and function in primary and immortalized cells, thus emerging as a novel potential drug target for CF.
