GoKawiilNature Communications retracts CCR5 frameshifting study over splicing artefact
The editors have retracted a paper claiming that a CCR5 mRNA sequence drives programmed -1 ribosomal frameshifting regulated by miRNAs and nonsense-mediated decay. A re-investigation found the original dual luciferase reporter contained a cryptic splice site that produced artefactual splice variants mistaken for frameshifting activity. When tested with an improved reporter lacking that splice site, the CCR5 sequence showed no detectable frameshifting, a result independently replicated by at least two other research groups.
GoKawiil's interpretation of the reporting above, not reported fact.
The retraction removes support for a proposed regulatory mechanism linking CCR5 expression, a gene central to HIV co-receptor biology, to ribosomal frameshifting and RNA decay pathways. It illustrates how reporter vector design flaws, such as cryptic splice sites, can produce misleading molecular biology results that pass initial peer review. The episode may prompt other labs using similar dual luciferase systems to re-examine prior findings for comparable artefacts.
- The paper's central claim about CCR5 frameshifting has been retracted due to a reporter vector artefact.
- A cryptic splice site in the original construct generated misleading splice variants mistaken for frameshifting signal.
- Independent replication by at least two other groups failed to detect any frameshifting activity using an improved reporter.
