Since MG-132 has also been proven to induce ER stress in many cell types (e.g., rat alveolar macrophages, renal angiomyolipoma cells, and human squamous lingual carcinoma cells) [35–37], we further determined whether MCPIP-1 could modulate ER stress in neutrophils. Here, ZC3H12A is linked to kidney angiomyolipoma.
