hsa-mir-211: Hsa-mir-211 is one of the eight miRNAs (hsa-miR-26a, hsa-miR-26b, hsa-miR-199-5p, hsa-miR-190, hsa-miR-204, hsa-mir-211, hsa-miR-218 and hsa-miR-369-3p) that were selected in a study [PMC5520514]. The study aimed to identify miRNAs that may play a role in melanoma progression and metastasis. Hsa-mir-211 is a microRNA (miRNA) that regulates gene expression by binding to the messenger RNA (mRNA) of target genes [PMC5520514]. The study found that among the selected miRNAs, hsa-mir-211 was one of the potential regulators in melanoma progression and metastasis [PMC5520514]. However, it was found that another miRNA called hsa-miR181b had the most potential target genes and had a significant influence on melanoma progression and metastasis [PMC8728391]. Hsa-mir181b is also an miRNA that regulates gene expression by binding to mRNA [PMC8728391]. The study suggests that both hsa-mir211 and hsa-mir181b may play important roles in melanoma progression and metastasis. However, further research is needed to fully understand their mechanisms of action and potential therapeutic applications.
