Physiological mechanical loading suppresses cancer cell proliferation in the heart through Nesprin-2-dependent nuclear mechanotransduction and epigenetic remodeling.

“Given that Nesprin-2 itself is unlikely to be directly druggable, targeting downstream epigenetic pathways or therapeutically mimicking mechanical load may represent promising anticancer strategies.”
“Increased mechanical load promoted Nesprin-2 signaling, which then led to changes in chromatin compaction and histone methylation, resulting in the suppression of cancer growth.”
Cardiac mechanical load acts as an endogenous tumor suppressor by remodeling the cancer epigenome via Nesprin-2, providing a mechanobiological explanation for the rarity of cardiac metastases.
In a recent study published in Science , Ciucci et al. show that physiological mechanical loading suppresses cancer cell proliferation in the heart through Nesprin-2-dependent nuclear mechanotransduction and epigenetic remodeling. 1 These findings identify cardiac mechanics as an endogenous barrier to cancer and suggest new mechanically and epigenetically informed therapeutic strategies.

Papavassiliou et al. (2026) conducted an editorial in Cancer (cardiac metastases). Mechanical loading vs. Mechanical unloading or static conditions was evaluated on Cancer cell proliferation and tumor growth. Physiological mechanical loading suppresses cancer cell proliferation in the heart through Nesprin-2-dependent nuclear mechanotransduction and epigenetic remodeling.
