Pretreatment of the unstimulated and TGF-β1 stimulated IPF HLFs with GB0139 reduced the level of galectin-3 and β1 integrin colocalization in a concentration-dependent manner (panels B1, B3, B5, B7 for unstimulated cells and panels B2, B4, B6, B8 for cells stimulated with TGF-β1). The gene discussed is TGFB1; the disease is idiopathic pulmonary fibrosis.
