Abstract:

Bortezomib (BTZ) can inhibit the proliferation of many kinds of cell. Studies have shown promising evidence of BTZ in the treatment of multiple myeloma and tumor. To date, researchers have believed the proliferation and migration of pulmonary artery smooth muscle cells (PASMC) play as the two major causes that induce the excessive thickening and remodeling of the distal pulmonary arteries (PA), which drives the disease pathogenesis of pulmonary hypertension (PH). Lately, a number of recent studies have indicated that BTZ can effectively suppress the PH development in multiple commonly used PH rat models via inhibiting the distal PA remodeling and PASMC proliferation. However, neither the underlying molecular mechanism nor the related clinical relevance are fully understood and remain future dissection. Therefore, in this review, we briefly summarize the recent published literature, which provide mechanistic evidence to guide the utilization of BTZ as a potential novel treatment option in PH and other pulmonary vascular diseases.

Key words: bortezomib, pulmonary hypertension
