ABSTRACT
A variety of full 2ʹ-F/OMe-modified siRNAs were designed and synthesized, and the activity against hepatocellular carcinoma Huh-7 and HepG2 cells was evaluated. K&A DNA/RNA H-8 synthesizer was used to synthesize siRNAs, and neutral cytidinyl lipid DNCA mixed with cationic lipid CLD were used to transfect siRNA. By RT-qPCR and CCK-8 assay, the target gene silence and the proliferation of Huh-7 and HepG2 cells were detected. The siRNAs loading into Ago2 protein was detected by RNA-binding protein immunoprecipitation. Drug uptake and cell apoptosis were detected by flow cytometry, and the expression of PLK1 protein was detected by Western blot. Partial full 2ʹ-F/OMe modified siRNAs, especial siPLK1A3, increased the uptake of Huh-7 cells, enhanced their binding to Ago2 and gene silencing activity, down-regulated PLK1 protein, as well as induced more Huh-7 cell apoptosis and proliferation inhibition activity. It provides important data for the development of novel siRNA modification patterns and anti-HCC formulations.
ABSTRACT
Type II innate lymphoid cell (ILC2) is a newly identified innate immunological cell that belongs to the lymphocyte lineage in cell morphology, resides in the body's mucosal tissues, and has the dual functions of innate and adaptive immunity to promote tissue remodeling and repair after injury. Additionally, it is involved in the occurrence and development of a variety of liver diseases and plays an important role in maintaining the immunological homeostasis of the liver region. This article reviews the differentiation, development, and biological functions of ILC2, with particular attention to the research progress in liver diseases.
