Emerin expression stratification across breast cancer subtypes.

ABSTRACT: Nuclear dysmorphism is a critical indicator of tumor aggressiveness, influencing cancer cell invasion and metastasis. Emerin, an integral nuclear envelope protein involved in nuclear architecture, is important for maintaining nuclear integrity. Our previous work demonstrated an inverse correlation between nuclear envelope-localized emerin expression and breast cancer aggressiveness. However, it failed to have the power to assess whether emerin loss correlates with cancer stage, grade, proliferation, or molecular phenotype. Here we analyzed emerin expression at the nuclear envelope across 243 breast cancer patient samples encompassing various tumor grades, stages, and molecular phenotypes. We found significantly reduced emerin expression in invasive ductal carcinoma (IDC), invasive lobular
