UTHealth Houston BLMP6 Peptide Selectively Binds Fibulin-4 in Metastatic Triple-Negative Breast Cancer
Mikhail Kolonin's group at UTHealth Houston published preclinical data showing BLMP6, a peptide identified through AI-guided modeling, selectively binds fibulin-4 — a protein highly expressed on metastatic triple-negative breast cancer cells — and not on noninvasive breast cancer or normal breast tissue. A BLMP6 conjugate carrying monomethyl auristatin E suppressed metastasis and improved survival in mouse models, and BLMP6-based fluorescent imaging probes successfully detected metastatic lesions. The paper, published in Molecular Therapy Oncology, identifies fibulin-4 as a new theranostic target.
