ANXA1 expression

The study demonstrated that a CAM subtype, CAM-A-induced formation of aberrant structures from HBV core protein aggregates in the nucleus leading to cell death by ANXA1-driven apoptosis. Thus, CAM-A treatment may lead to the specific elimination of HBV-infected cells by apoptosis, paving the way to novel therapeutic strategies for viral cure.

Taken together, ANXA11 mediates cisplatin resistance through sEV miRNA resorting. Mechanically, ANXA11 binds to miR-148a-3p in a sequence-specific manner to regulate its resorting and thus influences tumor proliferation and chemoresistance.

This research uncovers a novel role of macrophage ANXA1 in pancreatic cancer. ANXA1-mediated regulation of efferocytosis by tumor-associated macrophages promotes antitumor immune response via STING signaling, suggesting potential treatment strategies for pancreatic cancer.

MicroRNA-374a-5p (miR-374a-5p) and microRNA-374b-5p (miR-374b-5p) were identified as inhibitors of ANXA1 expression and PI3K/AKT pathway activity, thereby inhibiting macrophage M2 polarization. Furthermore, miR-374a-5p and miR-374b-5p were observed to suppress PTC cell proliferation through their regulatory action on ANXA1. Our study suggests that miR-374a/b-5p inhibits PTC cell growth by blocking the macrophage M2 polarization induced by exosomal ANXA1.

Furthermore, MDX-124 significantly inhibited tumour growth in both the 4T1-luc triple-negative breast and Pan02 pancreatic cancer syngeneic mouse models (p < 0.0001). These findings suggest ANXA1-targeted therapy is a viable and innovative approach to treat tumours which overexpress ANXA1.

Annexin-A1 gene silencing promoted cell proliferation and inhibited apoptosis, blocked cells in the S-phase, and increased cell migration, leading to an increase in the number of invaded cells. Above all, Annexin-A1 could reflect the differentiation degree and lymph node metastasis of ESCC cells to some extent and was involved in the invasion, metastasis, proliferation, and other biological behaviors of ESCC cells, indicating an experimental basis for Annexin-A1 as a molecular marker in the early diagnosis of ESCC and the prediction of cell metastasis, invasion, and differentiation degree.

Our findings highlighted that treatment with sericin and melatonin alleviated the testicular tissues in mice from oxidative stress and dysregulated spermatogenesis and steroidogenesis engendered by DEN.

Our findings suggest that RRM2 regulates docetaxel resistance in prostate cancer by stabilizing ANXA1-mediated activation of the PI3K/AKT pathway. Targeting RRM2 or ANXA1 may offer a promising therapeutic strategy to overcome docetaxel resistance in prostate cancer.

hrANXA1 promoted malignant growth and metastasis in mice by increasing the infiltration and M2 polarization of tumor-associated macrophages (TAMs), generating an immunosuppressive TME and suppressing the antitumor CD8+ T-cell response. Together, our findings reveal that ANXA1 may be an independent prognostic factor for HCC and demonstrate the clinical translational significance of ANXA1 for tumor immunotherapy in HCC.

Loss of ANXA1 leads to uncontrolled transformation of normal fibroblasts into cancer-associated fibroblasts (CAFs), which can be enhanced by secreted TGF-β from malignant epithelial cells. Given the role of CAFs in cancer, our study underscores ANXA1/FPR2 signaling as an important crosstalk mechanism between epithelial cells and fibroblasts in promoting ESCC.

ANXA1 may serve as an independent prognostic biomarker for ES patients and is associated with metastasis and the immunosuppressive microenvironment in ES, which needs to be validated in further studies.
