A prognostic model of idiopathic pulmonary fibrosis constructed based on macrophage and mitochondria-related genes.

Background: Studies have shown that mitochondrial function and macrophages may play a role in the development of idiopathic pulmonary fibrosis (IPF). However, the understanding of the interactions and specific mechanisms between mitochondrial function and macrophages in pulmonary fibrosis is still very limited.

Methods: To construct a prognostic model for IPF based on Macrophage- related genes (MaRGs) and Mitochondria-related genes (MitoRGs), differential analysis was performed to achieve differentially expressed genes (DEGs) between IPF and Control groups in the GSE28042 dataset.

Flavonoid accumulation in cell suspension cultures of Glycyrrhiza inflata Batal under optimizing conditions.

Cell growth and flavonoid production in cell suspension cultures of Glycyrrhiza inflata Batal were investigated under various initial inoculum densities, and sucrose and nitrogen concentrations to develop an optimization method for an improved flavonoid production. Both biomass accumulation and flavonoid production exhibited an "S" curve in one culture cycle, with the greatest value obtained on day 21, which showed that cell growth and flavonoid biosynthesis went along isochronously. Moreover, according to the biomass and flavonoid production, the appreciate inoculum density, and the sucrose and nitrogen concentrations were 50 g FW L(-1), 50 g L(-1) and 120 mmol L(-1), respectively.
