Neovascularization (NV), as a cardinal complication of several ocular diseases, has been intensively studied, and research has shown its close association with inflammation and immune cells. In the present study, the role of interleukin-17A (IL-17A) in angiogenesis in the process of ocular NV both in vivo and in vitro was investigated. Also, a paracrine(More)
Interleukin-23 (IL-23) is a heterodimeric cytokine that consists of p19, a novel subunit, and p40, which is shared by IL-12. IL-23 has been demonstrated to play an important role in autoimmunity and tumor growth. However, the role of IL-23 in ocular neovascularization (NV) diseases remains unclear. In this study, we explored the role of IL-23 in the(More)
An efficient one-pot synthesis of trisubstituted allenes from readily available terminal alkynes and ketones is realized. A wide range of trisubstituted allenes may be synthesized efficiently via this method. Preliminary mechanistic studies revealed that CuI and Ti(OEt)4 are in charge of the formation of propargylic amine, while ZnBr2 is responsible for the(More)

The S-adenosylmethionine synthetase gene (metK) from Streptomyces avermitilis was cloned into multi-copy vector pIJ653 and integrative vector pSET152 yielding two metK expression plasmids pYJ02 and pYJ03, respectively. When wild-type strain ATCC31267 was transformed with these two plasmids, avermectin production was increased about 2.0-fold and 5.5-fold,(More)
The aim of the present study was to characterize the phenotypic shift, quantity and role changes in different subgroups of retinal macrophages in a mouse model of oxygen-induced retinopathy (OIR). The mRNA expression levels of macrophage M1 and M2 subgroup marker genes and polarization-associated genes were analyzed by RT-qPCR. The number of M1 and M2(More)
The well-established A(3) coupling reaction of terminal alkynes, aldehydes, and amines provides the most straightforward approach to propargylic amines. However, the related reaction of ketones, especially aromatic ketones, is still a significant challenge. A highly efficient catalytic protocol has been developed for the coupling of aromatic ketones with(More)
GyrI-like proteins are widely distributed in prokaryotes and eukaryotes, and recognized as small-molecule binding proteins. Here, we identify a subfamily of these proteins as cyclopropanoid cyclopropyl hydrolases (CCHs) that can catalyze the hydrolysis of the potent DNA-alkylating agents yatakemycin (YTM) and CC-1065. Co-crystallography and molecular(More)
