hsa-mir-376c: Hsa-mir-376c is a microRNA that has been found to be up-regulated in tumors of long-survivors [PMC2804711]. In a study by Song et al, 16 microRNAs were identified as being overexpressed in the sera of patients with gastric cancer (GC), but further investigation suggested that only hsa-miR-221, hsa-miR-744, and hsa-mir-376c were potential biomarkers [PMC5431292]. The study by Song et al focused on the identification of microRNAs as potential biomarkers for GC [PMC5431292]. Hsa-mir-376c was found to be overexpressed in the sera of GC patients and was suggested as a potential biomarker for this disease [PMC5431292]. Additionally, ALK tyrosine kinase receptor precursor mRNA was identified as a putative target of hsa-mir-376c [PMC2804711]. The up-regulation of ALK tyrosine kinase receptor precursor mRNA in tumors of long-survivors suggests that it may play a role in tumor progression and survival [PMC2804711]. These findings highlight the potential importance of hsa-mir-376c and its target ALK tyrosine kinase receptor precursor mRNA in GC and tumor progression. Further research is needed to fully understand their roles and potential clinical applications.
