Article Abstract
Background: Aurora kinase A (AURKA) and tumor-infiltrating lymphocytes (TILs) are both known to play an essential role in tumorigenesis. However, the expression and prognostic value of the AURKA and TILs in medullary thyroid carcinoma (MTC) have not yet been investigated.
Patients And Methods: Surgical specimens and clinical data of 137 patients diagnosed with MTC were collected. AURKA expression and TILs infiltration were quantified by immunohistochemistry and hematoxylin-eosin staining. Subsequently, the prognostic value of AURKA expression and TIL infiltration in MTC was evaluated.
Results: AURKA was highly expressed in patients with multifocal tumor, cervical lymph node metastasis, and an advanced TNM stage, indicating a high probability of recurrence. AURKA further exhibited a positive correlation with TILs (R = 0.44, < 0.001). High expression of AURKA combined with a low numbers of TILs (AURKA/TILs) was identified as an independent prognostic factor for biochemical recurrence (odds ratio: 4.57, 95% confidence interval: 1.54-14.66, < 0.01) and recurrence-free survival (hazard ratio: 3.64, 95% confidence interval: 1.52-8.71, < 0.001). The combination of AURKA and TILs apparently improves the prognostic value for biochemical recurrence (area under the curve: 0.751) and structural recurrence (area under the curve: 0.836) of MTC. Notably, AURKA/TILs demonstrated a high value for prediction of distant or unresectable locoregional recurrence, with an overall accuracy of 86.9%.
Conclusion: AURKA is associated with the MTC malignancy. The combination of AURKA/TILs was identified as novel independent prognostic marker in MTC, predicting incurable disease recurrence with high accuracy.

Aurora kinase A (AURKA) is a serine/threonine kinase that plays a critical role in cell cycle regulation, particularly during mitosis. Recent studies have identified AURKA as an oncogene overexpressed in various cancers, including gastric cancer (GC). This review summarizes the molecular mechanisms by which AURKA contributes to GC pathogenesis, including its roles in cell proliferation, apoptosis inhibition, epithelial-mesenchymal transition (EMT), and cancer stemness.

Innate immune cells can acquire a memory phenotype, termed trained immunity, but the mechanism underlying the regulation of trained immunity remains largely elusive. Here, we demonstrate that inhibition of Aurora kinase A (AurA) dampens trained immunity induced by β-glucan. ATAC-seq and RNA-seq analysis reveal that AurA inhibition restricts chromatin accessibility of genes associated with inflammatory pathways such as JAK-STAT, TNF, and NF-κB pathways.

Introduction: leaves (FSL), a traditional Chinese ethnomedicinal herbal material used to prepare health-promoting infusions and pharmacologically noted for their robust anti-inflammatory, antioxidant, and broad-spectrum antiviral activities, nevertheless have an as-yet-uncharacterized molecular mechanism of action against human adenovirus (HAdV).
Methods: Ultra-high-performance liquid chromatography coupled with Q-Exactive Orbitrap mass spectrometry (UHPLC-Q-Exactive-Orbitrap/MS) was employed to identification of FSL components. Publicly available GEO datasets were mined to identify HAdV-associated differentially expressed genes (DEGs).

Anti-epidermal growth factor receptor (EGFR) therapies are the most recommended first-line treatment for wild-type unresectable metastatic colorectal cancer (CRC) according to the European Society for Medical Oncology guidelines. However, primary resistance renders this treatment ineffective for almost 40% of patients. Our previous work identified Aurora kinase A (AURKA) as a key resistance driver through non-canonical, Hippo-independent Yes-associated protein 1 (YAP1) activation.

Background: Adenocarcinoma of Lung (LUAD) remains a leading cause of cancer-related deaths across the globe, and patients harboring epidermal growth factor receptor (EGFR) mutations frequently develop resistance to targeted therapies. While aurora kinase A (AURKA) has been implicated in tumorigenesis, its involvement in regulating ferroptosis via the kelch-like ECH-associated protein 1 (KEAP1)/NF-E2-related factor 2 (NRF2)/heme oxygenase 1 (HO‑1) signaling axis in EGFR-mutant LUAD remains poorly understood.
Methods: We analyzed RNA-seq and clinical data from 594 LUAD samples from The Cancer Genome Atlas (TCGA) to explore associations between AURKA expression, EGFR mutation status, and immune cell infiltration.
