Associated gene: -
Associated microRNA: -
Biological function: Potential liquid biopsy biomarker for detecting GC and differentiating GC from controls/gastritis; higher levels associate with more aggressive clinicopathological features.
Molecular mechanism: Not specified; study focuses on diagnostic performance and stability/secretory characteristics rather than mechanistic targets.
Biological pathway or process:

not specified

Detected method:
Q
S
Validation methods:

RNA-seq; RT-qPCR; Clinical Sample Validation; ROC Analysis; Cohort Study; Bioinformatics Analysis; Back-Splice Junction PCR / divergent primers PCR; Sanger Sequencing; RNase R Treatment; Actinomycin D / DRB Stability Assay; Transfection; Agarose Gel Electrophoresis

Clinical significance:

Upregulated in serum of GC patients; discriminates GC from controls (AUC 0.909) and contributes to a diagnostic model (GC-DM). Elevated expression correlates with multiple clinicopathological parameters (e.g., lymph node metastasis, TNM stage).

Description:

hsa_circ_0001185 is significantly up-regulated in the serum of gastric cancer patients (also elevated in gastritis vs healthy controls) and shows strong diagnostic performance (AUC 0.909). It is included with hsa_circ_0005265 in a multicenter logistic-regression diagnostic model (GC-DM) and its higher expression correlates with more aggressive clinicopathological features such as lymph node metastasis and advanced TNM stage.

Confidence score:

0.7734
