To examine the mechanism regarding the inhibition of symptoms and associated inflammatory responses of BLM-induced pulmonary fibrosis by Aptamin C, changes in the expression of Sodium-dependent Vitamin C Transporter-1/2 (SVCT-1/2), the specific channel proteins involved in the absorption of vitamin C into cells or tissues, were examined. The gene discussed is SLC23A1; the disease is pulmonary fibrosis.
