Hsa_circ_0000092 up-regulates IL24 by SMC1A to induce macrophages M2 polarization.

ABSTRACT:

Introduction

Hepatocellular carcinoma (HCC) as the malignant cancers with high morbidity. The EMT of HCC has closely linked to the metastasis and recurrence. Moreover, tumor-associated macrophages (TAMs) can interact with HCC cells in the immune microenvironment; the M2 polarization of TAMs enhance the HCC cells EMT. The mechanism between HCC cells and TAMs is still unclear and our study was aimed to uncover it.

Methods

We performed RT-qPCR and western to detach the RNA and protein expression. The relationship among has_circ_0000092, U2AF2, SMC1A and IL24 were revealed through mechanism experiments. Rescue assays were implemented to determine how circ_0000092 modulates M2 polarization of TAMs.

Results

As detected by RT-qPCR, has_circ_0000092 was with high expression i
