Neuregulin-induced HER3 activation drives migration in head and neck squamous cell carcinoma via HER2 and FAK signaling pathways.

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
purposeTo investigate the role of neuregulin (NRG) signaling in promoting head and neck squamous cell carcinoma (HNSCC) migration through HER3-dependent pathways and to assess the therapeutic potential of targeting the NRG/HER3 axis in mitigating perineural invasion.
methodsNRG-driven migration was studied using DRG co-culture, wound healing assays, and HER3 inhibition (shRNA, AV-203). The biological function and biochemical effects of the HER3/HER2/FAK axis in response to NRG were analyzed via phosphorylation assays, knockdown, western blotting, and cell staining for protein expression.
resultsNRG promoted directional migration of FaDu and TU138 HNSCC cells through HER3/HER2 and HER3/PI3K interactions. HER3 inhibition (shRNA or AV-203) abolished HER3 phosphorylation, disrupted HER3-HER2 interactions, and suppressed AKT and ERK signaling. Wound healing assays confirmed that NRG enhances migration via HER3 activation. NRG also induced HER3-dependent FAK phosphorylation, and FAK knockdown or inhibition with PF228 significantly reduced NRG-driven migration, highlighting the critical role of HER3-FAK signaling.
conclusionNRG promotes HNSCC cell migration by activating HER3, forming HER3-HER2 and HER3-FAK complexes, and driving downstream AKT, ERK, and FAK signaling. Targeting the NRG/HER3 axis holds potential as a therapeutic strategy to address perineural invasion and associated clinical challenges in HNC.
