HER2 as a molecular trojan horse in prostate cancer: mechanistic insights and therapeutic unlocks.
Review in Molecular biology reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Human epidermal growth factor receptor 2 (HER2/ERBB2) is a well-established therapeutic target in breast and gastric cancers, but its relevance in prostate cancer (PC) remains unresolved. Although HER2 gene amplification is relatively uncommon in PC, heterogeneous overexpression has been observed, particularly in advanced and castration-resistant PC (CRPC), where it is frequently associated with aggressive clinicopathological features. Experimental studies portray HER2 as a signaling hub, mediating crosstalk with androgen receptor (AR) signaling to sustain tumor growth under androgen-deprived conditions. Concurrent activation of the HER2-PI3K-AKT axis further promotes cell survival, proliferation, and therapeutic adaptation. Moreover, HER2 cooperates with epidermal growth factor receptor (EGFR) and NF-κB pathways, reinforcing tumor plasticity and resistance mechanisms. Despite these compelling biological insights, clinical translation has been disappointing. Early trials with Trastuzumab, Lapatinib, and Pertuzumab yielded minimal benefit, underscoring patient heterogeneity, pathway redundancy, and the lack of biomarker-guided stratification. Lessons from these failures highlight the need for precision oncology approaches that integrate molecular profiling and rational therapeutic combinations. Recent advances, including next-generation HER2-targeted antibody-drug conjugates, bispecific antibodies, and CAR-T cell therapies, as well as strategies combining HER2 inhibition with AR signaling blockade, PI3K/AKT inhibitors, or immunotherapy, offer renewed promise. HER2 in PC thus represents a paradox: biologically significant but clinically underexploited. Reframing HER2 within the AR-PI3K signaling network and leveraging biomarker-driven strategies may finally unlock its therapeutic potential. This review critically examines HER2 in PC, analyzing its mechanistic roles, therapeutic potential, and the challenges that shape its value as both a prognostic biomarker and actionable target.
