Article Abstract
Interferon regulatory factor 2 (IRF-2) is known to play a pivotal role in the development and progression of several malignancies. As a crucial member of interferon regulatory factor family, the association between the expression of IRF-2 and clinical prognostic significance has not been fully explored in colorectal cancer (CRC). The purpose of our study was to investigate the expression profile of IRF-2 in CRC and to examine its association with clinical features. The expression levels of IRF-2 in 18 paired CRC and non-cancerous colorectal tissues were measured by quantitative real-time PCR (qRT-PCR) and those in 4 paired samples by Western blotting. The results showed a significant increase in IRF-2 mRNA expression and protein expression in CRC tissues compared to those in paired normal tissues. Besides, high expression of IRF-2 was significantly associated with distant metastasis (P = 0.041) and preoperative serum CEA level (P = 0.045). Kaplan-Meier survival analysis showed that patients with high expression of IRF-2 had a significantly worse overall survival than those with low expression of IRF-2 (P = 0.006). Further multivariate analysis indicated that IRF-2 and TNM stage were independent prognostic factors for overall survival in patients with CRC. Our study primarily suggests IRF-2 as a potential prognostic biomarker in CRC.

Acute myeloid leukemia (AML) presents significant treatment challenges due to its heterogeneity and resistance to conventional therapies. This study explored the role of 2'-5'-oligoadenylate synthetase 3 (OAS3) in AML progression and its potential as a prognostic and therapeutic biomarker. Through bioinformatics analysis, OAS3 was found to be significantly upregulated in AML patients and associated with poor clinical outcomes.

Two major macrophage populations in the steady-state liver, resident Kupffer cells (KCs) and monocyte-derived macrophages (MoMFs), contribute crucially to the unique physiological functions of the organ. Much remains to be learned, however, about how the differentiation and functions of these cell populations are regulated. We found here that Ly6C-MHCII+ MoMFs were severely reduced in mice lacking interferon (IFN) regulatory factor-2 (IRF-2) (Irf2-/- mice) but restored to the normal frequencies by introducing type I IFN receptor deficiency, indicating that IRF-2 supports MoMF differentiation through attenuating excess type I IFN signals.

OAS-RNase L is a double-stranded RNA-induced antiviral pathway triggered in response to diverse viral infections. Upon activation, OAS-RNase L suppresses virus replication by promoting the decay of host and viral RNAs and inducing translational shutdown. However, whether OASs and RNase L are the only factors involved in this pathway remains unclear.

Article Synopsis
- - Preeclampsia (PE) affects 4.6% of pregnancies and contributes to significant maternal and perinatal health issues; this study explores the role of circular RNA circPCNXL2 in PE progression.
- - Using various assays, the research found that silencing circPCNXL2 increased the proliferation and migration of trophoblast cells, while also raising levels of miR-487a-3p and lowering IRF2 levels, suggesting a regulatory interaction between these elements.
- - The study concludes that circPCNXL2 promotes PE by inhibiting trophoblast cell functions through the miR-487a-3p/IRF2 pathway, highlighting potential targets for future therapeutic strategies. *
