BLM-treated mice lung tissue homogenates showed a significant increase in phospholipid levels as compared to saline-treated control mice. with VEGF-inhibitor (CBO-P11), not only showed recovery of lung tissue as observed by histopathology, but also showed downregulation of proteins and pathways driving fibrosis [23]. Here, we report that correction of fibrotic tissue and protein dysregulation with CBO-P11 co-treatment was accompanied by a decrease in total lipid content and specific downregulation of lipids, which was reversed in response to BLM treatment. Dysregulated lipids identified in this study hold the potential of being future biomarkers for IPF. More importantly, this study broadens the treatment options for a disease beset by limited options by identifying potential therapeutic targets in the form of metabolic and biochemical processes which leave behind these lipids as a cellular fingerprint. Materials and Methods: Materials: VEGF-inhibitor CBO-P11 was obtained from Calbiochem (San Diego, CA). BLM sulfate was obtained from Sigma-Aldrich (St. Louis, MO). Antibodies against Acetyl-CoA carboxylase (ACC), phospho-Acetyl-CoA carboxylase (Ser79) (pACC), Fatty Acid Synthase (FASN), AMP-activated protein kinase (AMPK), phosphor-AMP-activated protein kinase (pAMPK), alpha-smooth muscle actin (-SMA), HRP-conjugated anti-rabbit IgG antibody and HRP-conjugated anti-mouse IgG antibody were obtained from Cell Signaling Technology (Danvers, MA).

Mice were housed in a barrier facility with specific pathogen-free conditions, and all experiments were performed using protocols authorized by the Old Dominion University or college (ODU) animal facility. Briefly, mice were anesthetized with isoflurane. In the 1st set of experiments, either BLM sulfate or equivalent quantities of saline as control was given intranasally. In a separate arranged, BLM-treated mice were co-treated every other day time by intraperitoneal injection of CBO-P11 (0.3 mg/kg) starting at day 0 and continuing until the mice were euthanized at day-28. Bronchoalveolar lavage (BAL) fluid was collected after the trachea was revealed and cannulated having a 20-gauge catheter. After instillation of 1 1 ml of chilly sterile phosphate buffered saline (PBS) three times through the trachea into the lung, BAL fluid was recovered at 90% of the original volume. The BAL fluid was centrifuged for 10 min at 1500 rpm and the cell-free supernatant was stored at ?80C. The lungs were perfused with 5 ml of chilly saline through the remaining ventricle and surgically eliminated. The remaining lungs were used to evaluate the fibrotic score by histological exam, and the right lungs were homogenized to analyze protein and lipid levels. Preparation of Lipid Draw out from Lung Samples: The dissected lung cells was slice into 2 mm2 and utilized for lipid/cholesterol extraction. Cells was suspended with 610 L M-PER mammalian protein extraction reagent with Halt proteases inhibitors (Thermo Scientific) to make tissue lysates. Cells lysates were then transferred to Matrix A fast-prep tubes (MP Biomedical) and ruptured 20 mere seconds at a rate of (4.0 m/s) twice without break. Cells lysates were later on centrifuged at 10,000g for 10 min at 4C and then the supernatant (500 L) was transferred from each tube to labeled glass tubes on ice.
