Circular RNAs (circRNAs) are emerging as crucial regulators in the complex biology of cancer, yet their specific roles in ICC metastasis remain poorly defined. In this study, circRNA sequencing of paired primary and recurrent ICC tissues revealed that elevated expression of circRNA PICALM (circPICALM) is strongly linked to ICC metastasis and patient prognosis.2026/04/15GSE291554GSM8837541GSM8837540GSM8837542GSM8837538GSM8837537GSM883753924676291554Homo sapiens[41776633]
