Insufficient information to provide a gene function summary for SCAI (suppressor of cancer cell invasion). The provided PubMed abstracts exclusively concern clinical practice guidelines and cardiogenic shock classification systems published by the Society for Cardiovascular Angiography and Interventions (also abbreviated SCAI), a medical professional organization. These documents address the management of acute coronary syndromes, peripheral artery disease, pulmonary embolism, chr9 coronary disease, and cardiogenic shock in adult patients. None of the abstracts contain molecular or biological information relevant to the SCAI gene located on chromosome 9, its tumor suppressor function, mechanism of action through MRTFA/SRF transcriptional regulation, or its role in cell migration and Rho signaling pathways. To provide an accurate gene function summary grounded in peer-reviewed evidence, abstracts from studies investigating SCAI gene biology, protein interactions, transcriptional mechanisms, or cancer-related phenotypes would be required.
