circRNA-disease information
Expression pattern:
DN
Associated gene: CCL5, INSC, SLC9A1, SLC34A1, EFNA5
Associated microRNA: hsa-miR-614, hsa-miR-645, hsa-miR-4689
Biological function: Potential tumor-suppressive circRNA reduced in colorectal cancer spheroids and metastatic lesions; predicted upstream regulator of oncogenic miRNAs and downstream tumor-suppressive genes involved in cancer stemness and CRC progression.
Molecular mechanism: Predicted circRNA-miRNA-mRNA regulatory network/ceRNA mechanism involving oncogenic miRNAs and downstream tumor-suppressive targets; hsa_circ_0039776 is proposed to regulate the hsa-miR-645-EFNA5 axis.
Biological pathway or process:

ceRNA regulation (other); apoptosis (promotes); proliferation (inhibits); stemness (inhibits); metastasis (inhibits); JAK/STAT (other); cell cycle (other); other pathway/process (other)

Detected method:
S
Validation methods:

RNase R Treatment; circRNA-seq; Bioinformatics Analysis; Clinical Sample Validation; Survival Analysis

Clinical significance:

Potential diagnostic biomarker and therapeutic target in colorectal cancer; stepwise loss from normal colon mucosa to primary CRC and hepatic metastases suggests relevance to tumor progression.

Description:

hsa_circ_0039776 was identified as a potential tumor-suppressive circRNA that is reduced in CRC spheroids and metastatic lesions, with stepwise loss from normal mucosa to primary CRC and hepatic metastases. The study proposes that it acts through a circRNA-miRNA-mRNA network, especially the hsa_circ_0039776-hsa-miR-645-EFNA5 axis, to modulate CRC progression and cancer stemness.

Confidence score:

0.5746
