Abstract
Retinopathy of prematurity (ROP) is a retinal vascular proliferative disease occurring in premature and low birth weight infants, which is the leading cause of blindness and low vision in children. Laser photocoagulation is still recognized as the gold standard of treatment in ROP. Recently, anti-vascular endothelial growth factor (VEGF) therapy has become a novel alternative approach in clinical practice for ROP. However, there are still many improper and deviations in identifying indications and selecting therapeutic modalities, resulting in generalization and abuse of anti-VEGF drugs in treatment of ROP. The aim of this article is to summarize and objectively evaluate the treatment indications and methods of ROP based on related research at home and abroad, in order to strictly control the theraputic indications and scientifically and rigorously select appropriate therapeutic modalities for the benefit of children with ROP.

Abstract
Ganoderic acids (GAs) are well recognized as important pharmacological components of the medicinal species belonging to the basidiomycete genus Ganoderma. However, transcription factors directly regulating the expression of GA biosynthesis genes remain poorly understood. Here, the genome of Ganoderma lingzhi is de novo sequenced. Using DNA affinity purification sequencing, we identify putative targets of the transcription factor sterol regulatory element-binding protein (SREBP), including the genes of triterpenoid synthesis and lipid metabolism. Interactions between SREBP and the targets are verified by electrophoretic mobility gel shift assay. RNA-seq shows that SREBP targets, mevalonate kinase and 3-hydroxy-3-methylglutaryl coenzyme A synthetase in mevalonate pathway, sterol isomerase and lanosterol 14-demethylase in ergosterol biosynthesis, are significantly upregulated in the SREBP overexpression (OE::SREBP) strain. In addition, 3 targets involved in glycerophospholipid/glycerolipid metabolism are upregulated. Then, the contents of mevalonic acid, lanosterol, ergosterol and 13 different GAs as well as a variety of lipids are significantly increased in this strain. Furthermore, the effects of SREBP overexpression on triterpenoid and lipid metabolisms are recovered when OE::SREBP strain are treated with exogenous fatostatin, a specific inhibitor of SREBP. Taken together, our genome-wide study clarify the role of SREBP in triterpenoid and lipid metabolisms of G. lingzhi.
